Advanced Driver Assistance Systems (ADAS) use vehicle sensors, such as radar, cameras, light detection (LIDAR), night vision and Ultrasound, to perceive the world around them. The vehicle then uses the information for passive and active driver support, also known as driver aids. Simple ADAS regulates speed through cruise control, where more complex processing will lead to full vehicle automation. However, ADAS primary purpose is to prevent accidents and save lives.
Optical Image Sensors or cameras represent the world in the colour spectrum RGB, much like the human eye. They allow cars to respond to the same prompts intended for Human drivers, traffic lights, signs by the road and pedestrians. Reduced light and visibility decrease the effectiveness of cameras dramatically.
RADAR works well in all conditions with short and long-range detection, which is why it is suited to provide constant feedback for
driving at speed and preventing collisions. Other ADAS can be more precise but less consistent.
LiDAR uses lasers and therefore is well suited to working in the dark and makes detailed representations of the surrounding area. LiDAR can detect tiny objects, but particulates degrade their performance in the atmosphere.
GPS / GNSS is used for navigation and communicating with satellites. GPS provides
accurate location information coupled with an up-to-date map database.
SONAR sensors are excellent at proximity range-finding, such as parking manoeuvres and are accurate over limited space. They are only practical for tasks within a few feet of distance. Variations in the environment can interfere with readings, making them unreliable at speed.
ADAS systems are either passive or active. Passive ADAS use the sensors to inform the driver of potentially unsafe feedback for the driver to act upon. In an ACTIVE ADAS system, the vehicle takes direct action.
Lane departure warning (LDW) systems warn the driver if they leave a marked lane without using the indicator, or if the vehicle is drifting out of its lane.
A forward-collision warning system uses sensors in the vehicle to scan the road ahead of for obstacles such as other vehicles, fixed objects, and even pedestrians. While driving, FCW measures the speed and distance of the vehicle and nearby objects.
This technology uses parking sensors fitted to the front, back and sides of the car, which detect spaces and obstacles. Basic versions will control the steering - turning the wheel automatically - while the driver stays in charge of the accelerator, brake and gear changes.
Electronic stability control (ESC) helps prevent the vehicle losing control by stabilising when it begins to veer off its intended path.
Anti-lock braking systems (ABS) help steering in emergencies by restoring traction to the tyres. This helps prevent wheels from locking up – possibly allowing the driver to steer to safety. What It does not do is shorten stopping distance and it is normal for the pedal to vibrate or push back.
Traction Control (TC) helps reduce slippage or wheel-spin on slippery roads. It is always ON except when you push the button on your dash to manually switch it off.
Modern vehicles now feature advanced driver assistance systems (ADAS) for improved safety, but this has also increased repair costs due to sophisticated sensors and cameras. Technicians require proper training and tools to recalibrate these components. Vehicles are becoming more like computers, with connected info-tainment systems and over-the-air software updates, raising concerns about cybersecurity and changing risk profiles.
The UK government recently approved its first automated driving system, the Automated Lane Keeping System (ALKS), which can control steering, acceleration, and braking under specific conditions. Under the Automated and Electric Vehicles Act 2018, insurers will be liable for accidents during automated driving mode but can seek compensation from other liable parties.
of all traffic deaths could be prevented by ADAS systems.
Incorrect calibration could lead to sudden braking.
Towards the end of 2022, over half of all claims included a scan.
62%
Precision of calibration needs to be down to milimetres.
There is at least 1 sleep related death every day in the UK.
It is estimated that ADAS-equipped vehicles are significantly more expensive to repair
ADAS sensor calibration is dictated by OE methodology but is usually required when working in the area of any ADAS related components. Damage to these components can occur in a collision, even a minor bump, or by-product of common service work such as windscreen replacement, suspension repairs or wheel alignment.
When ADAS systems are incorrectly calibrated, or not calibrated at all, sensors may feedback false information to the ECU which can lead to issues such as not acting or alerting the driver when there is an obstacle. The liability ultimately will fall to the repairer who according to Thatcham’s IIR are responsible for the complete repair of the vehicle. Any collision resulting from incorrectly calibrated ADAS systems can lead to costly legal battles.
We as an industry have to be better at servicing the technology of the future that is assisting us in maintaining safe driving conditions.
Every death and serious injury on the road is a preventable tragedy and yet, on average, five people die every day on the road in the UK and 84 are seriously injured.
Thatcham Research was established by the motor insurance industry in 1969, with the specific aim of containing or reducing the cost of motor insurance claims while maintaining safety standards.
This insurer funded research centre has involvement and engagement with vehicle manufacturers, regulators, law enforcement organisations, automotive bodies and insurers.

Identify the presence of ADAS on the vehicle and ensure it is recorded.
Then, ensure repair procedures clearly identified if inspection, realignment and calibration are required and why.
Complete all relevant inspection, realignment and calibration activities as retained within the repair procedures.
Inspection, calibration, realignment and road tests are carried out by a currently competent person.
Ensure the calibration results confirm that the sensors are functioning within the vehicle manufacturer’s technical specification.
Produce fully verifiable and auditable records and provide a copy to the asset owner/work provider.
The increasing amount of automotive electronic hardware and software requires significant changes in today’s automobile repair process to service the complexity of the modern car parc.
The trend is shifting from distributed ADAS electronic controller units (ECUs) to a more integrated ADAS domain controller with centralised ECUs. This means that we are currently at what SAE International designates as Level 2 (Partial Driving Automation), where the vehicle can control both steering and accelerating/decelerating but falls short of self-driving because a human sits in the driver’s seat and can take control of the car at any time.
As cutting edge vehicles drive the innovation of ADAS within the car parc we expect to see greater varients in the levels of automation available and the complexity of the ADAS within the vehicles. This means that the level of complexity needed in providing repair will increase. As it currently stands, the industry is experiencing an enormous skills gap which will only increase unless repairers are able to keep up with the relevant training and equipment needs.
