Detailed recording of these procedures is essential for warranty compliance and proper safety system verification.
Dynamic vs Static Calibration Methods
A key component of Advanced Driver Assistance Systems (ADAS) is guaranteeing 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 environment like a workshop. This requires a level surface, controlled lighting, and professional calibration instruments. This method provides high precision, but it demands a designated area and tends to be time-consuming. It's less flexible and requires substantial facility costs but guarantees consistent results, independent of weather.
In contrast, the dynamic method, or on-road calibration, takes place while the vehicle is being driven. This method needs clear weather, visible road markings, and controlled driving speeds. You'll benefit from its flexibility, as it evaluates the system in practical scenarios and needs less dedicated tools. However, it relies significantly on weather and road conditions, and the performance can differ.
Deciding between these methods is based on specific vehicle needs, manufacturer requirements, and your facility's capabilities. Frequently, both calibrations are essential to ensure ideal ADAS performance, especially after services like glass installations or alignment services.
Each approach needs professional expertise and must be approached with precision to preserve system integrity.
Diagnostic Procedures for Camera and Radar Systems
Modern ADAS vehicles require careful diagnostic procedures for sensing systems to guarantee reliable functionality.
