Thorough documentation of these processes is crucial for meeting warranty requirements and effective verification of safety systems.
Dynamic vs Static Calibration Methods
A key component of Advanced Driver Assistance Systems (ADAS) is maintaining precise calibration, which is performed through both static and dynamic methods.
Static calibration procedures takes place with the vehicle immobile, usually in a controlled environment like a workshop. This requires a level floor, regulated lighting, and specialized calibration tools. This method provides high precision, but it demands a specialized facility and tends to be time-consuming. It's more rigid and requires substantial facility costs but guarantees consistent results, independent of weather.
In contrast, the dynamic method, or on-road calibration, is performed while the vehicle is being driven. This approach requires clear weather, visible road markings, and controlled driving speeds. This method offers its flexibility, as it assesses the system in practical scenarios and requires less specific hardware. However, it is greatly influenced by weather and road conditions, and the outcomes may fluctuate.
Selecting from these methods is based on vehicle requirements, manufacturer requirements, and your workshop's resources. Often, both calibrations are required to maintain ideal ADAS performance, especially after services like glass installations or wheel balancing.
Each approach demands professional expertise and needs to be handled carefully to preserve system integrity.
Camera and Radar System Diagnostics
Today's ADAS-equipped vehicles need careful diagnostic procedures for vision and radar components for flawless operation.
