Advanced Driver Assistance Systems & Current Vehicle Systems

When working on vehicles equipped with ADAS, you must perform both dynamic and static calibration to ensure exact system diagnostics for cameras and radar units.

Maintain awareness of the latest software updates and programming to maintain the accuracy of safety systems and meet warranty specifications.

Detailed recording of these processes remains critical for meeting warranty requirements and proper verification of safety systems.

Static vs Dynamic Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is ensuring precise calibration, which is performed through two main methods.

Static calibration takes place with the vehicle at rest, often in a controlled setting like a workshop. You'll need a level floor, controlled lighting, and professional calibration instruments. This approach offers high precision, but it requires a designated area and can be time-consuming. It's more rigid and requires substantial facility costs but guarantees consistent results, not influenced by weather.

Alternatively, the dynamic method, or mobile calibration, is performed while the vehicle is being driven. This process requires clear weather, visible road markings, and controlled driving speeds. The advantage lies in its flexibility, as it assesses the system in practical scenarios and needs less dedicated tools. However, it relies significantly on weather and road conditions, and the outcomes may fluctuate.

Choosing between these methods hinges on automotive specifications, manufacturer specifications, and your facility's capabilities. In many cases, both calibrations are essential to maintain ideal ADAS performance, specifically after services like windscreen changes or wheel balancing.

Each approach needs professional expertise and should be approached with precision to maintain system integrity.

ADAS Camera and Radar Diagnostics
