Increasing numbers of new cars are equipped with
Advanced Driver Assistance Systems (ADAS). Some of the more common ones include
forward collision warning, automatic emergency braking, adaptive cruise
control, lane departure warning, lane keeping assist, blind spot monitoring,
rear cross traffic alert, parking assist/self-parking, adaptive headlights that
steer with the vehicle, and automatic headlight high-beam activation and
To do their jobs, ADAS rely on inputs from a
variety of sensors that allow the systems to “see” what is happening around the
vehicle. The most common are camera, radar and ultrasonic sensors. Steering
sensors are also used to help determine the direction of vehicle travel. Some
systems use information from a single type of sensor, but others combine
information from multiple sensors – a process called sensor fusion – to obtain
a more accurate “view” of the situation.
Most ADAS sensors are very precisely aimed and
require calibration if their positions are disturbed in any way. Consider that
a sensor out of alignment by a fraction of an inch or even one degree on the
vehicle will be aimed at an area significantly off axis 50 or more feet down
the road. Misaimed sensors often result from collisions – even a minor fender
bender can knock ADAS sensors out of alignment. However, calibration can also
be required as a by-product of common vehicle service work such as windshield
replacement, suspension repair or wheel alignment.
Instant Windscreens has invested
in providing Calibration equipment for all our major capital city stores. Our staff
at these stores, have been trained to perform calibration on most vehicles.
Our selected branches which have
the Calibration equipment have designated areas where the calibration is
performed. In each of these areas, our technicians can set up specific target
boards for each vehicle which allows the car computer to be re-calibrated.
Once the targets are set up
according to the vehicle manufactures specifications, one of our technicians
will then connect to the car computer by a hand held device. The device then
goes through a number of procedural steps to initiate the car’s computer to re-calibrate.
Calibrations can take up to 2 hours to do on specific cars.
There are two forms of ADAS
calibration, static and dynamic. General descriptions of these processes can be
provided, but the exact procedures vary significantly from one vehicle
make/model to the next. In all cases, the automaker’s specified procedures and
instructions are precisely followed by Instant Windscreens.
Car manufacturers are increasingly
adding new technology to vehicles which will provide Instant Windscreens a
unique opportunity to provide that one stop shopping option for customers that
have cars with ADAS.
Call 132 444 to talk to one of our
dedicated ADAS branches when you have a glass that needs to be replaced and
calibrated. There may also be a need to get a car recalibrated after an event like a
small accident, tyre changes, wheel alignment or suspension impacts so call us
to get advice if Instant Windscreens can to the recalibration. We recommend
recalibrating your vehicle at least once a year to ensure that it functions
