Detailed recording of these processes is essential for meeting warranty requirements and reliable verification of safety systems.

Comparing Static and Dynamic Calibration Methods

An essential element of driver assistance systems is maintaining precise calibration, which is performed through either static or dynamic methods.

The static calibration process takes place with the vehicle stationary, usually in a controlled environment like a workshop. You'll need a level floor, controlled lighting, and specialized calibration tools. This method offers high precision, but it necessitates a dedicated workspace and can be time-consuming. It's less adaptable and requires substantial facility costs but delivers predictable performance, not influenced by weather.

On the other hand, the dynamic method, or mobile calibration, is performed while the vehicle is being driven. This process requires clear weather, visible road markings, and particular vehicle velocities. The advantage lies in its flexibility, as it assesses the system in actual driving situations and requires less dedicated tools. However, it is greatly influenced by weather and road conditions, and the performance can differ.

Deciding between these methods is based on specific vehicle needs, OEM guidelines, and your facility's capabilities. In many cases, both calibrations are necessary to maintain ideal ADAS performance, especially after services like glass installations or wheel balancing.

Each method needs specialized skills and should be handled carefully to ensure system integrity.

Camera and Radar System Diagnostics

Modern ADAS vehicles require a meticulous approach to diagnosing camera and radar systems to ensure optimal performance.

Initiate diagnostics with checking all sensors for damage or obstruction. You must retrieve any stored fault codes which could reveal component issues or positioning problems. Confirm the placement of all components based on OEM requirements.
