Thorough documentation of calibration steps is crucial for warranty compliance and reliable verification of safety systems.

Dynamic vs Static Calibration Methods

A key component of driver assistance systems is guaranteeing precise calibration, which can be accomplished through either static or dynamic methods.

The static calibration process is conducted with the vehicle immobile, typically in a controlled setting like a workshop. The process demands a level floor, regulated lighting, and specific calibration equipment. This technique offers high precision, but it necessitates a designated area and is often time-consuming. It's less flexible and incurs higher facility costs but delivers reliable outcomes, independent of weather.

In contrast, dynamic calibration procedures, or mobile calibration, is performed while the vehicle is in motion. This method demands clear weather, visible road markings, and specific driving speeds. The advantage lies in its flexibility, as it evaluates the system in actual driving situations and demands less dedicated tools. However, it is greatly influenced by weather and road conditions, and the results can vary.

Selecting from these methods is based on specific vehicle needs, manufacturer requirements, and your service center's capacity. Often, both calibrations are required to maintain ideal ADAS performance, especially after services like windscreen changes or wheel balancing.

Each approach requires specialized skills and should be handled carefully to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems

Modern ADAS vehicles require careful diagnostic procedures for vision and radar components for flawless operation.
