ADAS Calibration and Alignment - Mansfield and Ashfield

Audi A5 in for ADAS camera calibration after windscreen replacement.

When the windscreen is replaced, it is vital the camera alignment is carried out. On this car it highlighted the fact that the windscreen fitters hadn’t actually located the camera in its bracket correctly, so deactivating several safety features such as lane assist and automatic cruise control.

The alignment board has to be set at an exact measured position from the car, then the camera uses the position of the dots to confirm it’s angle of view.

I thought I’d do a small write up on how systems in cars are now totally integrated, and how a seemingly simple job can escalate quickly.

A four year old Mercedes was presented for mot, it passed but with an advise for the rear tyres wearing on the edge and near the tread limit.

Now this should be a simple repair, replace tyres and carry out a four wheel alignment to ensure the new tyres wear correctly.

However, in the centre of the windscreen are the cameras for lane departure and traffic sign recognition systems, and behind the front grill badge is a radar for automatic cruise control and emergency brake assist.

Adjusting the wheel alignment will change the angle of view for these systems, and at worst, render them useless.

So now a straight forward tyre replacement has become a full ADAS calibration.

But does it need to be done?

Lane assist systems can be turned off, however emergency braking cannot, and how would the insurance company react if the car was in an accident with one or more systems faulty or uncalibrated.

From next year emergency braking is required to be fitted on all new cars, that’s how important it is considered to be.

But don’t worry, we’re trained and equipped to deal with these systems.

This VW Passat was presented to us with the radar cruise control not working.

We quickly diagnosed that the system was unhappy with the horizontal alignment of the radar head.

On removing the grill we found one of the mounting brackets had broken, causing the alignment error.

On fitting a new mounting bracket, we then had to carry out an ADAS system alignment, to ensure the radar beam was parallel to the car, and also a four wheel alignment to make sure the car actually drove in a straight line down the road.

If the wheel alignment was not correct, and the car was even slightly “crabbing” as it was driven, the radar beam would not be pointing directly ahead, giving the possibility of false readings.

All carried out in-house, on our state of the art alignment and ADAS equipment.

Beautiful mk7 Golf gti in today, receiving ADAS radar calibration after a repair in the airbag/srs system highlighted faults in the collision avoidance system.

Correct alignment of the radar is critical for the correct operation of these systems. Take the diagram below, if the alignment was out, even by a couple of degrees, the red car wouldn’t see the blue car until the last moment, or would react unnecessarily to the presence of the green car.

What is ADAS?

Advanced driver-assistance systems (ADAS) are electronic systems that assist drivers in driving and parking functions. Through a safe human-machine interface, ADAS increase car and road safety. ADAS systems use automated technology, such as sensors and cameras, to detect nearby obstacles or driver errors, and respond accordingly.

Most road accidents occur due to human error. Advanced driver-assistance systems are systems developed to automate, adapt, and enhance vehicle systems for safety and better driving. ADAS’s automated systems are proven to reduce road fatalities by minimizing human error. Safety features are designed to avoid accidents and collisions by offering technologies that alert the driver to problems, implementing safeguards, and taking control of the vehicle if necessary. Adaptive features may automate lighting, provide adaptive cruise control, assist in avoiding collisions, incorporate satnav/traffic warnings, alert drivers to possible obstacles, assist in lane departure and lane centering, provide navigational assistance through smartphones, and provide many more features.

When does my ADAS need calibrating?

ADAS sensor calibration is required whenever a sensor’s aiming is disturbed in any way. This can occur in a collision, even a minor fender bender, or be a byproduct of common service work such as windshield replacement, suspension repairs or wheel alignment. Calibration is also called for whenever a sensor or its mounting bracket is removed and replaced, there is a change in tire size, a front airbag deploys and deflects off the windshield, or repairs are made to a car roof that has a sensor bracket mounted to it. Finally, sensor calibration is necessary when there is a related DTC in the car’s computer memory, or an automaker releases a technical service bulletin with instructions that calibration be done as part of another repair.
