ADAS and Modern Vehicle Systems

For vehicles featuring ADAS systems, technicians need to complete both static and dynamic calibration for ensuring precise system diagnostics for cameras and radar units.

Maintain awareness of the latest programming and software updates to preserve proper functioning of safety systems and adhere to warranty requirements.

Detailed recording of calibration steps is crucial for warranty compliance and proper verification of safety systems.

Comparing Static and Dynamic Calibration Methods

A key component of ADAS technology is maintaining precise calibration, which can be accomplished through either static or dynamic methods.

Static calibration procedures is conducted with the vehicle immobile, often in a specialized workspace like a workshop. This requires a level floor, controlled lighting, and professional calibration instruments. This technique offers high precision, but it demands a specialized facility and can be time-consuming. It's more rigid and requires substantial facility costs but delivers predictable performance, unaffected by weather.

On the other hand, dynamic calibration procedures, or on-road calibration, is performed while the vehicle is being driven. This approach needs clear weather, well-defined lane markers, and particular vehicle velocities. The advantage lies in its flexibility, as it assesses the system in real-world conditions and requires less dedicated tools. However, it is greatly influenced by weather and road conditions, and the results can vary.

Choosing between these methods hinges on vehicle requirements, OEM guidelines, and your facility's capabilities. In many cases, both calibrations are required to maintain ideal ADAS performance, particularly after services like glass installations or alignment services.

Each technique demands specialized skills and needs to be handled carefully to preserve system integrity.

Diagnostic Procedures for Camera and Radar Systems

Modern ADAS vehicles require a meticulous approach to diagnosing sensing systems to guarantee optimal performance.

Begin with checking all sensors to identify any blockages or damage. It's crucial to check for system error codes pointing to operational issues or alignment concerns. Verify sensor positioning based on OEM requirements.
