Comprehensive logging of calibration steps is essential for warranty compliance and proper safety system verification.

Static vs Dynamic Calibration Methods

An essential element of Advanced Driver Assistance Systems (ADAS) is ensuring precise calibration, which can be accomplished through both static and dynamic methods.

The static calibration process is conducted with the vehicle at rest, often in a controlled setting like a workshop. The process demands a flat surface, controlled lighting, and professional calibration instruments. This technique offers high precision, but it necessitates a specialized facility and tends to be time-consuming. It's less flexible and incurs higher facility costs but guarantees reliable outcomes, independent of weather.

Alternatively, the dynamic method, also known as mobile calibration, occurs while the vehicle is in motion. This approach demands clear weather, well-defined lane markers, and particular vehicle velocities. The advantage lies in its flexibility, as it assesses the system in practical scenarios and demands less specific hardware. However, it relies significantly on weather and road conditions, and the performance can differ.

Deciding between these methods depends on automotive specifications, OEM guidelines, and your service center's capacity. Often, both calibrations are necessary to guarantee ideal ADAS performance, particularly after services like windscreen changes or wheel alignments.

Each technique needs technical knowledge and needs to be handled carefully to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems
