Detailed recording of these processes is crucial for meeting warranty requirements and proper verification of safety systems.

Dynamic vs Static Calibration Methods

A key component of ADAS technology is ensuring precise calibration, which is achieved through both static and dynamic methods.

Static calibration is performed with the vehicle at rest, often in a controlled setting like a workshop. The process demands a level surface, regulated lighting, and specialized calibration tools. This approach offers high precision, but it demands a specialized facility and can be time-consuming. It's less adaptable and requires substantial facility costs but ensures consistent results, independent of weather.

On the other hand, the dynamic method, or on-road calibration, takes place while the vehicle is in motion. This method demands clear weather, visible road markings, and specific driving speeds. This method offers its flexibility, as it tests the system in practical scenarios and requires less dedicated tools. However, it relies significantly on weather and road conditions, and the results can vary.

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

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 sensing systems to guarantee optimal performance.

Initiate diagnostics with checking all sensors to identify any blockages or damage. Be sure to check for system error codes which could reveal system malfunctions or misalignment. Check each component's positioning based on OEM requirements.
