What is Advanced Driver Assistance Systems (ADAS)?


The Advanced Driver Assistance System (ADAS) uses image processing cameras, radar, light detection and ranging and other sensors to monitor vehicle surroundings and detect potentially dangerous situations to enhance safety through advanced situational awareness and reduce collision possibilities. Sensors used in ADAS include cameras, radars, lasers and ultrasound. They can detect light, heat, pressure and other variables used to monitor the state of vehicle. Usually they locate in the front and rear bumpers, side mirrors, vehicle cab and wind shield glasses.




What are the applications of Advanced Driver Assistance Systems (ADAS)?


ADAS typically includes Traffic Message Channel (TMC), Intelligent Speed Adaptation (ISA), Vehicular Communication Systems and other driver assistant systems. The systems are as follows | Vehicle Cab | (i) Lane Departure Warning System (ii) Lane Keeping Assist (iii) Traffic Sign/Signal Recognition (iv) Night Vision System (v) Driver Status Monitor (vi) Electric Vehicle Warning (vii) Hill Descent Control Front | (i) Parking Assist (ii) Adaptive Front/Lighting System (iii) Adaptive Cruise Control (iv) Pedestrian Detection (v) Emergency Brake Rear | (i) Reverse Image (ii) Parking Assist (iii) Rear Collision Warning Side | (i) Surround View (ii) Blind Spot Detection




When should I use the ADAS Calibration service?


Under normal circumstances and to ensure the integrity of the system is maintained we would advise conducting an ADAS calibration after general repair to suspension components, geometry adjustments, windscreen replacement, bodywork replacement or repair following an accident. When disassembling or reinstalling monitoring components such as cameras, radars, and sensors, replacing the vehicle ECU, or the vehicle height has been changed, auxiliary and other systems need to be calibrated. To provide an example the Adaptive Cruise Control (ACC) calibration needs to be performed in the following cases | (i) Repair or replace the Adaptive Cruise Control (ACC) radar sensor control unit (ii) ACC radar sensor deviation angle out of normal range (iii) Adjust position of the ACC radar sensor on the vehicle body (iv) Repair or replace bumper or radiator grill (v) Adjust chassis Our technicians are certified professionals who will provide you with the necessary safety advice to ensure the intergrity of your vehicles operating systems are managed and maintained following any works that you may have done at our workshop.




What does the ADAS front view camera do?


The front-view camera captures what is in front of the vehicle. It is used in a number of ADAS systems, including Lane Departure Warning (LDW), Lane Keeping Assist (LKA) and Traffic Sign/Signal Recognition (TSR) systems, often in conjunction with other sensors, cameras or sensing systems to provide input data.




What does the ADAS 360° camera do?


The 360° or Surround View Camera System uses multiple camera views to create one 360° top-down (bird’s eye) view surrounding the vehicle. This system is used in both passive (displayed instructions) and active (autonomous) vehicle parking assist systems.




What does the ADAS radar sensor do?


ADAS radar sensors detect fixed and moving objects at different distances around the perimeter of a vehicle. Different Radar types and frequencies are used in various ADAS systems. Ultra short-range radar (USRR) and short-range radar (SRR) provide data for blind-spot detection (BSD) and lane-change assist (LCA), while systems including adaptive cruise control (ACC) use longer range radar.




Why do I need to calibrate the ADAS system?


Your vehicle relies on the cameras/radars/lasers used by the ADAS being in the correct alignment to function properly. As the system is not automatically self adjusting it is important to ensure the ADAS is calibrated to maintain the integrity of the vehicle's safety system. The consequences could be devastating if not.




How many different types of ADAS calibrations are there?


There are two types of calibration available: static and dynamic calibration. Depending on the vehicle make and model, either static or dynamic calibration is required. However, some vehicles will require both static and dynamic calibration to properly calibrate the system. Static calibrations require specific targets or patterns unique to each vehicle manufacturer. These types of calibrations must be performed indoors with the vehicle stationary throughout the calibration process. Dynamic calibrations are performed by driving the vehicle on public road under specific parameters such as vehicle speed, road condition, weather, and duration of time.




After collision repair, the vehicle did not have any MIL or DTC codes related to ADAS, do I still need to perform ADAS calibrations?


Depending on the repairs that were done, ADAS calibrations are highly recommended in the interests of safety. Some vehicle manufacturers require ADAS calibrations when certain parts (sensors, cameras, brackets, bumpers, etc) have been removed and installed regardless of any active MIL or DTC codes. The force from the collision could have bumped the ADAS sensors out of alignment. Performing the ADAS calibration will ensure the vehicle is returned to its pre-collision condition.




How is the ADAS calibration verified as being successful?


Once the calibration process is complete, a post-calibration diagnostic scan is performed to confirm any existing diagnostic trouble code has been cleared and a calibration certificate is issued along with any other necessary documentation following the workshop appointment. If the calibration was not successful, this would be investigated, communicated and addressed as necessary.




Are pre / post diagnostic scans performed?


Yes, a pre-calibration diagnostic scan is performed before any calibration. This verifies the vehicle’s equipped ADAS system and checks for any stored diagnostic trouble codes. After a successful ADAS calibration, a post-calibration diagnostic scan is also performed to verify all diagnostic trouble codes have been cleared.




How long does an ADAS calibration take?


ADAS calibrations can take up to 4 hours, depending on the vehicle make, model, and ADAS system to be calibrated.




Are your technicians certified to carry out an ADAS calibration?


Yes! We have invested in training, certification and equipment to provide this service.




Are you Insurance Industry Requirements (IIR) Compliant?


Yes! We meet requirements and are compliant with industry regulations.
