ADAS & Modern Vehicle Technologies

When servicing vehicles fitted with ADAS, technicians need to complete both dynamic and static calibration to ensure exact camera and radar system diagnostics.

Maintain awareness of newest programming and software updates to ensure precision of safety systems and adhere to warranty requirements.

Detailed recording of these procedures is crucial for meeting warranty requirements and proper safety system verification.

Comparing Static and Dynamic Calibration Methods

A crucial aspect of driver assistance systems is ensuring precise calibration, which is achieved through both static and dynamic methods.

The static calibration process takes place with the vehicle immobile, often in a controlled setting like a workshop. This requires a flat surface, regulated lighting, and specific calibration equipment. This method offers high precision, but it demands a designated area and can be time-consuming. It's less adaptable and incurs higher facility costs but ensures predictable performance, unaffected by weather.

On the other hand, the dynamic method, or on-road calibration, occurs while the vehicle is moving. This process demands clear weather, visible road markings, and particular vehicle velocities. The advantage lies in its flexibility, as it evaluates the system in real-world conditions and demands less dedicated tools. However, it relies significantly on weather and road conditions, and the results can vary.

Deciding between these methods depends on vehicle requirements, manufacturer specifications, and your facility's capabilities. Often, both calibrations are essential to ensure ideal ADAS performance, particularly after services like windscreen changes or wheel balancing.

Each method needs technical knowledge and should be executed precisely to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems

Modern ADAS vehicles require a meticulous approach to diagnosing vision and radar components for optimal performance.
