Detailed recording of calibration steps remains critical for warranty compliance and effective verification of safety systems.

Static vs Dynamic Calibration Methods

An essential element of Advanced Driver Assistance Systems (ADAS) is ensuring precise calibration, which is achieved through either static or dynamic methods.

Static calibration takes place with the vehicle stationary, usually in a controlled setting like a workshop. This requires a flat surface, regulated lighting, and professional calibration instruments. This method delivers high precision, but it necessitates a dedicated workspace and is often time-consuming. It's less adaptable and requires substantial facility costs but ensures predictable performance, independent of weather.

On the other hand, dynamic calibration, also known as mobile calibration, takes place while the vehicle is moving. This process needs clear weather, visible road markings, and particular vehicle velocities. You'll benefit from its flexibility, as it assesses the system in actual driving situations and requires less specialized equipment. However, it relies significantly on weather and road conditions, and the results can vary.

Deciding between these methods depends on automotive specifications, manufacturer requirements, and your facility's capabilities. Often, both calibrations are essential to ensure ideal ADAS performance, particularly after services like glass installations or wheel alignments.

Each approach requires technical knowledge and must be executed precisely to ensure system integrity.

Diagnostic Procedures for Camera and Radar Systems

Today's ADAS-equipped vehicles need thorough assessment of sensing systems to guarantee optimal performance.
