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. Purpose: to increase 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.
ADAS usually includes Traffic Message Channel (TMC), Intelligent Speed Adaptation (ISA), Vehicular Communication Systems and other driver assistant systems. The specific systems are as follows:
1) Lane Departure Warning System
2) Lane Keeping Assist
3) Traffic Sign/Signal Recognition
4) Night Vision System
5) Driver Status Monitor
6) Electric Vehicle Warning
7) Hill Descent Control
1) Parking Assist
2) Adaptive Front/Lighting System
3) Adaptive Cruise Control
4) Pedestrian Detection
5) Emergency Brake
1) Reverse Image
2) Parking Assist
3) Rear Collision Warning
1) Surround View
2) Blind Spot Detection
Under normal circumstances, after repair in an accident, calibration of the relevant auxiliary systems need to be performed. 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.
For example: ACC calibration needs to be performed in the following cases.
1. Repair or replace the Adaptive Cruise Control (ACC) radar sensor control unit
2. ACC radar sensor deviation angle out of normal range
3. Adjust position of the ACC radar sensor on the vehicle body
4. Repair or replace bumper or radiator grill
5. Adjust chassis
Perform the following steps prior to setting-up calibration toolset.
① Park the vehicle on a flat and level surface with its front wheels pointing straight and ensure there are no objects
in front of the vehicle.
② The vehicle’s coolants and engine oil should be at recommended levels and the gas tank full. The vehicle should
not be carrying any load (passengers or cargo).
③ Attach the VCI to the vehicle and connect the diagnostic tool to the vehicle (if connected through cable, please
pass cable through window).
④ Close the vehicle doors.
⑤ Adjust the tire pressure to the recommended value.
⑥ The preparation measures vary by vehicle and system. Please follow the instructions on the MaxiSys ADAS
tablet to ensure accurate calibration.
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.
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.
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.
To get the valuable ADAS calibration software, you can purchase the MaxiSys ADAS tablet or purchase the ADAS calibration software upgrade for your existing MaxiSys tablet.
Cameras, sensors, ultrasound, radar and LIDAR are some of the systems used to capture the driving environment data, including travelling or static vehicles position, pedestrian location, road sign, driving lane and intersection detection, road (curves) and driving conditions (poor visibility or evening driving), use that information to instruct the vehicle to take its predetermined action. Cameras, sensors and sensing systems are typically location in front and rear bumpers, windshield, front grill and side and rear view mirrors.
ADAS calibration procedures should be performed on a level floor. If an alignment lift is used for leveling, the Autel calibration software can provide adjustment information and the calibration frame can be easily raised or lowered to be level with the vehicle.
