ADAS and Modern Vehicle Systems

When repairing vehicles fitted with ADAS, technicians need to complete both dynamic and static calibration for ensuring exact system diagnostics for cameras and radar units.

Keep track of most recent software updates and programming to ensure proper functioning of vehicle safety features and meet warranty specifications.

Detailed recording of calibration steps remains critical for meeting warranty requirements and effective verification of safety systems.

Dynamic vs Static Calibration Methods

A crucial aspect of driver assistance systems is maintaining precise calibration, which can be accomplished through two main methods.

Static calibration procedures is conducted with the vehicle at rest, usually in a specialized workspace like a workshop. This requires a level surface, regulated lighting, and specialized calibration tools. This method provides high precision, but it necessitates a dedicated workspace and is often time-consuming. It's more rigid and incurs higher facility costs but delivers reliable outcomes, independent of weather.

In contrast, the dynamic method, or on-road calibration, is performed while the vehicle is moving. This method demands clear weather, visible road markings, and specific driving speeds. The advantage lies in its flexibility, as it evaluates the system in actual driving situations and demands less specialized equipment. However, it relies significantly on weather and road conditions, and the outcomes may fluctuate.

Selecting from these methods depends on automotive specifications, manufacturer requirements, and your workshop's resources. Frequently, both calibrations are essential to ensure ideal ADAS performance, specifically after services like windscreen changes or wheel balancing.

Each method demands professional expertise and should be approached with precision to preserve system integrity.

Camera and Radar System Diagnostics

Today's ADAS-equipped vehicles need thorough assessment of camera and radar systems to ensure reliable functionality.
