Detailed recording of these procedures remains critical for meeting warranty requirements and proper safety system verification.

Dynamic vs Static Calibration Methods

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

The static calibration process is performed with the vehicle at rest, typically in a controlled setting like a workshop. This requires a level surface, controlled lighting, and specific calibration equipment. This method delivers high precision, but it necessitates a specialized facility and is often time-consuming. It's less adaptable and involves greater facility costs but delivers consistent results, unaffected by weather.

In contrast, the dynamic method, also known as mobile calibration, occurs while the vehicle is being driven. This process demands clear weather, visible road markings, and particular vehicle velocities. This method offers its flexibility, as it tests the system in actual driving situations and requires less specific hardware. However, it relies significantly on weather and road conditions, and the results can vary.

Selecting from these methods depends on automotive specifications, OEM guidelines, and your workshop's resources. Often, both calibrations are necessary to maintain ideal ADAS performance, especially after services like windscreen changes or wheel balancing.

Each technique needs professional expertise and must be approached with precision to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems

Modern ADAS vehicles require a meticulous approach to diagnosing sensing systems to guarantee flawless operation.
