Detailed recording of these procedures is essential for warranty compliance and reliable verification of safety systems.

Static vs Dynamic Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is ensuring precise calibration, which can be accomplished through either static or dynamic methods.

Static calibration is conducted with the vehicle at rest, usually in a specialized workspace like a workshop. You'll need a flat surface, proper illumination, and specialized calibration tools. This technique provides high precision, but it demands a designated area and can be time-consuming. It's less flexible and involves greater facility costs but ensures predictable performance, unaffected by weather.

On the other hand, the dynamic method, also known as mobile calibration, is performed while the vehicle is in motion. This method needs clear weather, well-defined lane markers, and controlled driving speeds. The advantage lies in its flexibility, as it assesses the system in practical scenarios and needs less specific hardware. However, it relies significantly on weather and road conditions, and the outcomes may fluctuate.

Choosing between these methods depends on vehicle requirements, manufacturer specifications, and your facility's capabilities. Often, both calibrations are essential to guarantee ideal ADAS performance, particularly after services like windscreen changes or wheel alignments.

Each technique needs professional expertise and must be handled carefully to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems

Advanced driver assistance systems demand thorough assessment of vision and radar components for reliable functionality.
