ADAS & Modern Vehicle Technologies

When repairing vehicles fitted with ADAS, it's necessary to complete both dynamic and static calibration for ensuring exact system diagnostics for cameras and radar units.

Maintain awareness of newest programming and software updates to maintain the accuracy of vehicle safety features and meet warranty requirements.

Detailed recording of these procedures is essential for warranty compliance and reliable verification of safety systems.

Comparing Static and Dynamic 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 conducted with the vehicle immobile, usually in a controlled environment like a workshop. This requires a level surface, controlled lighting, and specialized calibration tools. This approach delivers high precision, but it demands a dedicated workspace and can be time-consuming. It's less flexible and involves greater facility costs but ensures consistent results, not influenced by weather.

Alternatively, the dynamic method, also known as mobile calibration, occurs while the vehicle is moving. This approach needs clear weather, clear road lines, and specific driving speeds. This method offers its flexibility, as it tests the system in practical scenarios and demands less specialized equipment. However, it relies significantly on weather and road conditions, and the outcomes may fluctuate.

Deciding between these methods hinges on automotive specifications, manufacturer specifications, and your facility's capabilities. In many cases, both calibrations are necessary to ensure ideal ADAS performance, especially after services like windshield replacements or alignment services.

Each technique needs technical knowledge and needs to be handled carefully to preserve system integrity.

ADAS Camera and Radar Diagnostics

Advanced driver assistance systems demand careful diagnostic procedures for vision and radar components for flawless operation.
