Advanced Driver Assistance Systems and Contemporary Vehicle Systems

For vehicles featuring ADAS systems, it's necessary to perform both dynamic and static calibration for ensuring accurate camera and radar system diagnostics.

Keep track of newest software updates and programming to ensure proper functioning of vehicle safety features and adhere to warranty requirements.

Detailed recording of calibration steps remains critical for warranty compliance and reliable safety system verification.

Dynamic vs Static Calibration Methods

A crucial aspect of Advanced Driver Assistance Systems (ADAS) is maintaining precise calibration, which is achieved through two main methods.

The static calibration process is performed with the vehicle immobile, usually in a controlled setting like a workshop. The process demands a level surface, proper illumination, and specialized calibration tools. This approach provides high precision, but it demands a dedicated workspace and can be time-consuming. It's less flexible and requires substantial facility costs but ensures reliable outcomes, not influenced by weather.

On the other hand, dynamic calibration, or on-road calibration, is performed while the vehicle is being driven. This process requires clear weather, visible road markings, and controlled driving speeds. The advantage lies in its flexibility, as it evaluates the system in actual driving situations and requires less dedicated tools. However, it is greatly influenced by weather and road conditions, and the results can vary.

Deciding between these methods depends on specific vehicle needs, manufacturer specifications, and your facility's capabilities. In many cases, both calibrations are required to maintain ideal ADAS performance, especially after services like windscreen changes or wheel balancing.

Each approach needs professional expertise and must be executed precisely to maintain system integrity.

ADAS Camera and Radar Diagnostics
