Under normal circumstances, after the accident is repaired, the relevant auxiliary systems need to be calibrated. When removing or reinstalling monitoring components, such as cameras, radars, sensors, replacing vehicle ECU. Or when the height of the vehicle changes, the auxiliary system and other systems need to be calibrated.
For example: ACC calibration needs to be carried out under the following circumstances:
1. Repair or replace the adaptive cruise control (ACC) radar sensor control unit
2. The deviation angle of the ACC radar sensor is beyond the normal range
3. Adjust the position of the ACC radar sensor on the body
4. Repair or replace the bumper or the parts that fix the front radar
5. Adjust the chassis
According to different vehicle types, calibration is divided into static calibration and dynamic calibration, or both are required.
1. Static calibration: Static calibration is generally completed in the workshop environment. It needs to use the calibration main frame and the target corresponding to the vehicle, and complete the calibration through the diagnostic software prompt.
2. Dynamic calibration: Dynamic calibration requires the vehicle to drive at a certain speed for a period of time under good road conditions, and to calibrate by identifying road signs or vehicles.
