Advanced Driver Assistance Systems (ADAS) – The Complete Guide

What are Advanced Driver Assistance Systems (ADAS)?

Advanced driver assistance systems is a technology that assists drivers. Its primary role is to prevent deaths and injuries by reducing the number of accidents and negating human error. It uses sensors and cameras to perceive the environment around the vehicle. Then it processes this data and either warn the driver or takes automatic action based on what it perceives. 

What ADAS applications include:

  • Pedestrian Detection/avoidance
  • Lane departure warning/correction
  • Traffic sign recognition 
  • Automatic emergency braking 
  • Blind spot detection 

ADAS is incredibly effective at preventing accidents. The Insurance Institute for Highway Safety found that it was 50% more likely to avoid front to rear crashes and 78% more likely to avoid backing crashes. 

Human error is unavoidable but ADAS is here to help!

How do Advanced Driver Assistance Systems Work? 

ADAS works by alerting drivers to potential dangers or taking automatic actions to avoid an accident. It gathers data from sensors and cameras to process its environment and quickly process the information into a warning or automatic response. 

ADAS is so useful as it’s able to aid humans and augment their current sensors. For instance, we can’t see in the dark very well, but RADAR can. We can’t see in all directions at once, but LIDAR sensors can. We can’t echolocate objects or people, but SONAR sensors can. 

This is why ADAS is amazing at reducing accidents, as it neutralizes human error and our inadequacies. The ADAS system consists of powerful processors and sensors to quickly integrate lots of data and make quick real-time decisions. Eventually, the technology will reach a point where we have fully autonomous car driving. 

Active vs Passive ADAS Systems

There are two types of ADAS systems:

Passive Advanced Driver Assistance Systems  – a passive ADAS system can have all the sensors of an active system but it merely just warns the driver of a potentially unsafe incident. Therefore, the driver must take action themselves to counteract the potential accident. This doesn’t completely remove the human error but does aid. These warnings come in the form of vibrations, warning sounds, flashing lights etc. 

Active Advanced Driver Assistance Systems  – an active ADAS system will contain all the necessary sensors but instead of just pre-warning the driver, it will autonomously make a decision to stop a potential accident from happening. Driving when there is no perceived warning the driver will still be able to engage in normal driving functions. 

What features do Passive ADAS Systems have?

A list of common features of Passive ADAS:

  • ABS – Anti-Lock Braking System: This stops the car from skidding when an emergency brake is used 

  • ESC – Electronic Stability Control: Assist in under or over steering, especially under difficult conditions.

  • TCS – Traction Control System: Uses a mixture of ABS and ESC to maintain traction control when turning corners. 

  • Back-up Camera : This provides the driver with a view behind the car when the car is being reversed. 

  • LDW – Lane Departure Warning : This simply alerts the driver if the car is not within its lane

  • FCW – Forward Collision Warning: This warns the driver when to brake in order to avoid an accident ahead

  • Blind Spot Detection: Warns the driver if there is someone or something in their blind spot 

  • Parking Assistance: This pre warns the driver when their front or back of the car is approaching an object, like a wall or lamp post. This would be used when parking your car. 

What features do Active ADAS Systems have? 

A list of common features of Active ADAS: 

  • Automatic Emergency Braking : Automatic brakes will be used when the ADAS sensors pick up an object, pedestrian, animal or anything that the car may collide with.

  • Emergency Steering : This will steer the car to avoid a collision with an object, pedestrian or animal the sensors may pick up.

  • Adaptive Cruise Control : This is cruise control that adapts to the speed of cars in front

  • Lane Assistance : Steers the car to make sure it stays within the lane

  • Traffic Jam Assist : This combines lane assistance and adaptive cruise control to help the driver through traffic

  • Self Parking : Maneuvers the car into a parking space

Benefits of Advanced Driver Assistance Systems 

There are many benefits to having ADAS installed on your car, and not just for safety reasons. 

  • Saves Fuel Consumption – ADAS improves the way people drive. It forces drivers to drive using efficient habits (eco friendly), and optimise EMS (Energy Management Strategy). The earlier and less harsh braking, controlled and constant speed etc. Research has found this has led to a 15% decrease in fuel consumption.

  • Helps to drive down costs (fewer accidents = less money spent) – ADAS is very effective at stopping accidents from happening. Both minor and major accidents, and in the long term this will mean less money spent on repairing the car after accidents, or finding replacements. Plus some insurers offer cheaper insurance if a car is fitted with ADAS.

Loss of Power in my Car: A Helpful Guide

There are lots of reasons there may be a loss of power in your car. It’s most noticeable when your foot is fully down on the accelerator and your car is not speeding up or is gradually losing power. A loss of power in your car can be frustrating, but not to worry Walker Cutting are here to help you with this helpful guide. After reading this you will be able to identify the common signs for a loss of power in a car, and be well on your way to fixing the loss of power in your car engine.

Technician fixing car

What Can Cause a Loss Power in a Car?

Your car may be losing power for many reasons but these reasons can be categorized into 3 general areas:

A Mechanical Issue – the loss of power in a car may be due a clogged fuel filter or low compression

A Malfunction of Actuators – the loss of power in a car is because of a bad spark plug, or bad fuel pump

A Malfunction of Sensors – the loss of power in a car due to any malfunction of sensors related to the EFI system 

Examples of Common Causes for a Loss in Power in a Car 

Fuel Filter Clogging

A clogged or dirty fuel filter means that impurities that should be being filtered are reaching the main engine and causing problems. This can lead to a loss of power in your car and even have lasting damage. 

Clogged Exhaust 

Over time your exhaust can begin to clog. It wise to check that there is no debris blocking the exhaust or get it cleaned every so often. If your exhaust is not performing to its best, this likely leads to a power loss in your car.

MAS (Mass Airflow Sensor) Problem 

If your MAS system is malfunctioning, its not able to communicate with the engine how much air flow is coming in and out. This could be a contributing factor to a loss of power in your car. 

Spark Plug Problems 

The spark plugs ignite the combustion in your engine and if there are issues with the spark plug your engine will suffer and lose power. A replacement is essential to stop the loss of power in a car.

Compressions Issues

This is an essential part of a car’s power. If your car’s cylinder compression is too low the loss of power in your car will be great. Get this checked over by an expert ASAP. 

Problems with the Fuel Pump 

The fuel pump supplies the engine with fuel, and is a vital part of the car’s performance. If there are problems with the fuel pump this may mean not enough fuel is reaching the engine causing a loss in power, as it won’t be able to reach full power without the necessary fuel. 

Issues with the Air Filter

The air filter will make sure no impurities are mixed into the engine, ensuring the car works to its maximum power potential. As any impurities getting through can impact the engine negatively. 

As you can see there are lots of reasons that your car may have a loss in power. It may be hard to identify which of the reasons it may be without professional help. Thankfully, a lot of these issues can be fixed by a simple cleaning service to get rid of the dirt, by a professional. After a cleaning service a car will be back to full power, as good as new. 

If you believe your car has lost its power for any of the reasons above. Contact us Here for a quick fix and leave with your car powered back up on the same day.

Loss of Power in my Car FAQs

Why is my car not accelerating when I press down on the gas?

All the reasons explained above could be contributing towards the loss of power in your car. In most cases it’s due to clogged exhaust or fuel pump, that requires a quick clean by a professional. Or usually a bad spark plug that is stopping your engine working to full power. 

Either way you should get the car checked out by a professional to fix the loss of power. 

Contact Us Here to get your car powered back up on the same day!

Signs of a bad fuel pump

An inefficient fuel pump is a contributing factor to a loss of power in a car. Here are a few signs to look out for to check if you have a bad fuel pump that may be affecting the power of your car.

Inconsistent acceleration

Car dies when under a heavy load

Sputtering – where the car starts but its performance while driving is questionable 

Contact us here to get your fuel pump fixed and your car back to its full power. 

Why would my car suddenly lose power while driving? 

The most likely issue is that a component is clogged. A clogged fuel filter is the most common reason, although a loss of power in your car could also indicate problems with the fuel pump or fuel line. Impurities or debris may be blocking the system, which causes the loss of power in a car.

    How to tell if your wheel alignment is off

    Your wheels may have become unaligned if you’ve been driving down bad roads, over potholes, or hit a curb. The alignment of your wheels can be negatively impacted by this. If your wheels are not properly aligned you risk wearing down your tyres significantly. It can also damage suspension and steering parts. This can create potentially dangerous driving conditions. Plus it means that your wallet may take a big hit if you need to replace tyres and car parts.


    This blog will help you identify the early warning signs. So that you can get it sorted by professionals asap to minimise the negative impacts that could be caused.


    How can I tell my wheel alignment is off? 


    There are a few signs that may indicate your car’s wheel alignment is off. However, the signs can be subtle and not always noticeable without professional equipment.  Here are some of the common signs:


    The car is veering to one side – This can easily be noticed by driving on a straight road. The car should drive straight on the road with very little effort on the steering wheel. If the car is pulling to either side that’s a sure sign the wheels need re-aligning. 


    Rapid or uneven tyre wear– tyre wear can speak volumes about the condition of a car. Wear on just the inside or outside of the tyre indicates a problem with camber adjustment. Feathering on tyre indicates toe adjustment. Any of these tyre wear or abnormalities in the tyre wear you should get your car checked out immediately. 


    Crooked steering wheel– If the steering wheel is off centre when driving on a flat straight road this is a clear sign. The steering wheel should be close to perfectly straight. Even if the wheel is out by a few degrees it’s important the wheels are realigned.  


    Screeching Tyres– Tyres shouldn’t make a noise during normal driving conditions. The screeching that you may hear is because the tyre comes into contact with the road in a way it wasn’t designed to. This could be due to wheel alignment. 


    Notice any of these alignment issues? Talk to our professionals here or call us at 01709 828220. 




    Car tyre care tips & maintenance

    As Autumn and Winter approach it’s important to make sure that you have carried out the proper checks on how to prepare your car for winter.

    One important aspect of your car that you need to make sure it is properly up to scratch is the condition of your tyres. 

    Your tyres see constant use and the most wear and tear out of all the consumables on your car. They’re also one of the most vital parts for your car’s safety.

    Why it’s important to properly care for your tyres

    You tyre tread is important for road safety as it gives your tyres grip on the road surface. During heavy or extended periods of rainfall, there will be a layer of water which your tyre treads will be used to push water out of the way.

    If your tyre treads wear down too much you could end up skidding or aquaplaning on the road at high speeds as your car fails to grip the road’s surface. 

    How to check your tyre tread depth

    The DVLA rules state that the minimum tread depth is 1.6mm, or about the size of the rim of a 20p coin. If any part of the tyre tread goes below the threshold, the tyres should be replaced immediately.

    Many modern tyres come with ways that let you quickly check the tread depth of your tyres. Usually this takes the form of a bump inside the tread groove which indicates where the minimum tread should be.

    Besides worn tyre treads, there are a few other signs to look out for that mean that your tyres may be unsafe and require assessment by a professional technician. These could be:

    • Cracks
    • Bulges
    • Knots

    You should check the condition of your tyres at least once a month in order to ensure that there are no issues that could compromise the safety of your vehicle.

    Checking your tyre pressure

    Making sure that you maintain properly inflated tyres is important for maintaining vehicle safety and a good fuel economy. 

    Your car’s manufacturer should specify the desired pressure for your tyres. If your tyres are under inflated, this will cause your engine to need to work harder and lead to increased fuel consumption over time. However, over inflated tyres have a smaller contact area with the road

    Wheel alignment and balancing car care guide

    It will come as no surprise that your vehicle’s wheels are incredibly important. They see the highest amounts of wear and tear when it comes to your car’s consumable parts. 

    However, many motorists often take their wheels, tyres and braking systems for granted and don’t think about how they can take care of them in order to preserve their longevity.

    In this blog we’ll break down wheel alignment, balancing and their effect on your car’s brakes and tyres and talk about the signs to look out for that means you need to take it to a garage to be realigned.

    What is wheel alignment and balancing?

    Wheel alignment refers to the angles of your cars wheels in relation to the road. In order to ensure that your tyres have equal contact with the road surface, these mechanisms are carefully calibrated to ensure that the tyres have equal pressure when driving.

    Balancing refers to the weight distribution on your wheels as they make contact on the road surface. 

    If your vehicle’s wheel alignment is skewed or if the wheels are slightly out of balance, this will cause some sizable issues with your vehicle. 

    The first issue is that uneven wheel alignment or unbalanced wheels will cause your tyres to wear unevenly. This could cause one of your tyres to wear past the UK road legal tyre tread depth of 1.6 mm which can be dangerous on roads when it rains. This also creates and issue with replacing your tyres, as you ideally want to replace 2 or 4 at once.

    The most hazardous issue created by misaligned wheels is that of fuel consumption. If one of your wheels has more of your vehicle’s weight bearing down on it, it will mean your engine needs to work hard to turn that wheel which will lead to increased consumption and higher fuel costs.

    Similarly to your tyres wearing unevenly, more weight on one wheel can also cause your brake pads to wear unevenly. While your brake pads are designed to wear down over time and be replaced, if one brake pad wears down more than the other you could end up damaging your car’s brake disk, which is a much more expensive repair.

    What causes your car’s wheels to become misaligned?

    Like many things with your car, general use can cause wear and tear on its consumables and mechanisms. 

    However, your wheel alignment and balance can be especially susceptible to being affected by things on the road. Driving your vehicle over things like pot-holes, curbs and rough roads frequently can cause wheel alignment to become skewed over time.

    Signs your car’s wheels are misaligned or unbalanced

    Without the high precision equipment, it can be difficult to tell if your wheels are misaligned or unbalanced. However, there are a few things that you can look for that will indicate that there might be an issue.

    • Feeling vibrations in your steering wheel which gets worse at higher speeds (this is a sign that your front wheels are misaligned)
    • Feeling vibrations in the driving seat which gets worse at higher speeds (this is a sign that your rear wheels may be misaligned)

    If you are experiencing any of these symptoms with your car, you should contact a garage to help fix your wheel alignment and balancing.

    How to fix wheel alignment and balancing

    Whether your car is 2-wheel or 4-wheel drive, keeping its wheel alignment in check will help prevent uneven wear on your tyres and reset your steering wheel for a more comfortable drive.

    Unfortunately, it’s almost impossible to fix your car’s wheel alignment at home using tools from your garage. You will need specialist equipment to detect the imbalances in your car’s wheels and then special equipment to fix them.

    Wheel alignment repair and wheel balancing services

    Readdressing your vehicle’s wheel alignment should be done regularly every one-to-two years alongside your regular service. 

    If you’re looking to carry out a routine wheel alignment and balancing check, or if you’re looking to fix some more developed issues. Contact us for our specialist wheel alignment service. As a Bosch accredited garage, we have access to high-end specialist equipment with expert technicians who strive to provide the best possible service to you.

    What Is A Full Car Service and How Important Is It For Your Car?

    UK law currently requires every motor vehicle to have an MOT test every year to ensure that the car is safe and roadworthy. An MOT test looks at the essential safety features and test for major faults that would make your car not roadworthy.  

    However, the test does not cover the condition of the engine, clutch or gearbox so in order to check the condition of these, you need a technician to take a more comprehensive look at your vehicle.

    This is where a full car service comes in. While passing an MOT test is mandatory, a full car service is optional. 

    What happens in a full car service?

    While a little more expensive than a traditional MOT, a car service involves a technician looking more in depth at your car into the systems that make it tick. A full car service is performed as a service at most MOT garages and includes, but is not limited to:

    • Changing the oil in the engine
    • Replacing the oil filter 
    • Replacing the air filter
    • Checking the wear on the car’s brake pads
    • Top ups of brake fluid, engine coolant and anti-freeze
    • Lubricating moving parts
    • Checking the condition of your engine’s spark plugs
    • Inspection of the engine
    • Inspecting the condition of the wheel bearings
    • Checking the condition of your tyres

    What are the advantages of a full car service?

    By keeping on top of the maintenance of your car, you’re helping to improve the longevity of the health of your car’s parts, which in the longer term can save you money from having to make big repairs. 

    For instance, as you use oil in your car and as it passes through your car’s oil filter, the oil will become thicker and dirtier over time. As a result, the oil becomes less efficient at lubricating your car’s engine and can lead to internal engine damage. 

    There are also a number of other components that if they have problems that are left unchecked, the impact on the long term health of your car and longevity of its parts could be costly. 

    Servicing your car is also a sign that it has been looked after while under your ownership. When you carry out a full service, you get to add a stamp to your car’s log book, which pays dividends when you come to sell your car.

      MOT Testing, Car Repairs, And Coronavirus: Everything You Need To Know

      Technician fixing car

      Are garages still open during the UK Lockdown?

      Following the UK Government’s advice on the 23rd of March that non-essential businesses should close, a list of services that are exempt from closing down was later published.

      Included in that list of essential businesses that were allowed to stay open were MOT test centres and garages. 

      What should you do if your MOT is due?

      As part of the overall effort to prevent the spread of Coronavirus, the Driver and Vehicle Standards Agency announced that MOT due dates for cars, vans, and motorcycles are to be extended by 6 months.

      The extension applies to MOTs due on and after 30th March 2020. However, if your MOT due date is before then, you must still take your car in for its MOT test in order for it to be roadworthy, unless you are self-isolating.

      So for example, if your MOT is due on the 10th April, your extended due date will be 10th October. You must get your MOT by then.

      You can see if your MOT has been exempted by checking your car’s MOT History online.

      Are Walker Cutting and Garages in Rotherham, and South Yorkshire Still Open?

      As garages are listed as an essential service, Walker Cutting will still remain open for all essential car repairs. That means if your car is showing signs of being unsafe, we would recommend that you speak to one of our technicians on 01709 828220. 

      We can talk through your car trouble over the phone and let you know what the best action is for you to take.

      From 30 March 2020, MOT due dates for cars, motorcycles and light vans will be extended by 6 months. This is being done to help prevent the spread of coronavirus.

      Why Should You Change Your Engine Oil?

      Maintaining your vehicle’s oil is an important aspect of your car’s maintenance. Due to the crucial part your engine oil plays in keeping your engine running. The job of the oil is to keep lubricating moving parts in the engine, preventing any wear to key engine components. Engine oil also helps regulate engine temperature, keeping the temperature consistent preventing overheating components.

      Oil changes in Rotherham

      We recommend checking your vehicle manufacturer manual to check how often you should change your oil. The normal recommendation is between 3,000 to 5,000 miles, depending on the average distances your car travels. With short distances and heavy traffic meaning, you may have to change your oil more often than someone who travels long distances with little traffic.

      If you decide to neglect oil changes you could be creating more problems that will be costly in the long run. As engine parts will wear out quickly causing them to warp, which can be costly to replace.

      An oil change can be performed by a professional technician, or you can do it by yourself if you have the know-how how to do it so. Walker Cutting offer low-cost vehicle services for your car, with your oil being changed in no time at all. Keeping your car running smoothly and efficiently as possible.

      What is Engine Flushing?

      Engine flushing is a method of cleaning your engine using a chemical additive. This additive flushes your engine of carbon deposits that may have built up over time. The additive is then left in the engine for several minutes while it idles, allowing the chemical to pass thoroughly through the entire engine system. These carbon deposits are a natural by-product of burning fuel, and are commonly found within your intake valves, combustion chambers, injector nozzles and engine pistons. These build ups can hinder your engine, causing it to lose out on power and general performance. Carbon deposits are quite common, especially in older cars, but if left untreated can cause serious damage to your engine. Engine flushing is often performed on older vehicles that have built up a large number of carbon deposits throughout its’ life. However, many manufacturers advise against performing an engine flush service on their modern cars, due to the improved self-sufficiency of modern engine systems. 

      Benefits of Engine FlushingEngine Oil | Walker Cutting

      Removing carbon deposits via engine flushing has numerous benefits for your vehicle. Not only is it essential in order to maintain a healthy engine system, this process also:

      Keeps your engine oil clean – Simply changing your engine oil does not remove all traces of your old oil from the engine. These residuals mix and dirty your new oil. Completing an engine flush before changing your oil will remove all traces of your old engine oil. 

      Cleans components inside your engine – Engine parts such as piston rings and valves can be significantly hindered by carbon deposits, and will affect the overall performance of your car. Flushing your engine will clean these components and restore efficiency.

      Helps prolong engine life – Keeping your engine free of potentially harmful carbon deposits will help your engine to stay healthy and maintain maximum efficiency and performance. The longer your engine stays clean, the healthier it is, and the longer it lasts.

      Does My Engine Need Flushing?

      When your car has gone a long time without an oil change, it is probably in need of an engine flush. This is because the older the oil, the less capable it is of removing carbon, therefore more carbon is allowed to stay in the engine and forms deposits. 

      If you have an older car, your mileage is likely higher and therefore your engine has had longer to build up deposits of soot and carbon. Older cars are prime candidates for engine flushing, while newer cars are sometimes advised not to flush their engine. If you drive a newer car, we advise that you check with your manufacturer before taking your car for an engine flush service.

      If you primarily drive in the city, or commonly drive for short amounts of time, your engine oil does not have enough to heat up and do its job properly. This leads to more carbon deposits forming over time, and your engine suffering because of it. Many drivers feel obliged to perform an engine flush when they don’t have much reliable maintenance history for their car. Cleaning their engine via flushing can give you more confidence in your engine system and stop you worrying about the engine’s history.

      Sometimes when internal work has been performed on the engine, this can lead to leftover particles being left in the engine, or external substances gaining access. This is more common when services are not performed in a sufficiently clean environment. If any of these points apply to you, considering an engine flush service for your car can prolong engine life and improve performance.

        Driving Tips For Pothole Safety

        Potholed in on the UK roads have become an underlying issue to UK motorists, especially with the damage potholes can cause to your vehicle. This has caused us to simply drive around them to avoid any damages, however some potholes are unavoidable. The recent weather in the UK has seen a rise in potholes up and down the UK roads, according to a study by AA customer’s nearly 39% of members claimed their cars have been damaged by potholes.

        What causes potholes?

        Potholes are created by groundwater that has gone into the crevices of the road, the water freezes and expands. When temperatures warm the water melts leaving holes within the layers of the asphalt creating the layers to collapse, creating big enough divots to cause vehicle damage.


        Pothole driving safety tips:

        Drivers can take measures to make sure their vehicle and passengers are safe from potholes. Driving more sensibly by slowing down before a pothole will help reduce the impact a pothole may make, however braking directly on a pothole can create more damage to your car tyres. A goPothole safety driving tipsod habit is also to create a little more space between you and the driver in front, this will help you to see the road ahead quicker, giving you the time to react to a pothole.

        Keeping a firmer grip on your steering wheel will benefit your handling of the vehicle. When driving over larger potholes can sometimes take charge of the direction of the car, so by having a firmer grip you are able to handle the car over the pothole.

        Making sure your tyres are in good condition is a good precaution to take when starting any journey, as poor quality damaged tyres will be affected more by potholes. It is recommended to have good quality tyres in good condition are better suited to dealing with potholes. Potholes can create tyre damage and even punctures, which creates problems and disrupt your journey.
