Comprehensive logging of these processes remains critical for meeting warranty requirements and effective safety system verification.

Dynamic vs Static Calibration Methods

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

The static calibration process is performed with the vehicle stationary, typically in a controlled setting like a workshop. This requires a flat surface, regulated lighting, and specialized calibration tools. This approach provides high precision, but it demands a dedicated workspace and is often time-consuming. It's more rigid and involves greater facility costs but guarantees predictable performance, unaffected by weather.

On the other hand, dynamic calibration procedures, or mobile calibration, is performed while the vehicle is in motion. This approach requires clear weather, visible road markings, and controlled driving speeds. This method offers its flexibility, as it evaluates the system in practical scenarios and demands less specific hardware. However, it relies significantly on weather and road conditions, and the performance can differ.

Deciding between these methods depends on specific vehicle needs, manufacturer requirements, and your workshop's resources. In many cases, both calibrations are required to ensure ideal ADAS performance, particularly after services like glass installations or alignment services.

Each method demands technical knowledge and needs to be handled carefully to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems

Today's ADAS-equipped vehicles need a meticulous approach to diagnosing sensing systems to guarantee reliable functionality.

Start by conducting a visual inspection of sensors for obstructions and physical damage. It's crucial to retrieve any stored fault codes pointing to system malfunctions or misalignment. Check the placement of all components following factory guidelines.
