Advanced Driver Assistance Systems & Current Vehicle Systems

When servicing vehicles fitted with ADAS, technicians need to complete both static and dynamic calibration to ensure exact camera and radar system diagnostics.

Keep track of the latest programming and software updates to ensure proper functioning of vehicle safety features and comply with warranty requirements.

Detailed recording of these processes is crucial for warranty compliance and effective verification of safety systems.

Comparing Static and Dynamic Calibration Methods

A crucial aspect of driver assistance systems is ensuring precise calibration, which is performed through two main methods.

Static calibration procedures takes place with the vehicle at rest, typically in a specialized workspace like a workshop. This requires a level floor, controlled lighting, and specific calibration equipment. This approach provides high precision, but it requires a designated area and is often time-consuming. It's less flexible and requires substantial facility costs but delivers reliable outcomes, not influenced by weather.

On the other hand, dynamic calibration, or on-road calibration, takes place while the vehicle is in motion. This approach demands clear weather, visible road markings, and specific driving speeds. This method offers its flexibility, as it evaluates the system in real-world conditions and needs less specific hardware. However, it relies significantly on weather and road conditions, and the outcomes may fluctuate.

Selecting from these methods depends on vehicle requirements, manufacturer specifications, and your workshop's resources. Often, both calibrations are required to ensure ideal ADAS performance, specifically after services like windshield replacements or wheel alignments.

Each technique needs specialized skills and needs to be handled carefully to preserve system integrity.

Diagnostic Procedures for Camera and Radar Systems

Modern ADAS vehicles require a meticulous approach to diagnosing camera and radar systems to ensure reliable functionality.
