Comparing Static and Dynamic Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is guaranteeing precise calibration, which is achieved through either static or dynamic methods.

Static calibration procedures is performed with the vehicle immobile, typically in a specialized workspace like a workshop. This requires a flat surface, regulated lighting, and professional calibration instruments. This approach delivers high precision, but it demands a dedicated workspace and is often time-consuming. It's less adaptable and incurs higher facility costs but guarantees predictable performance, not influenced by weather.

Alternatively, the dynamic method, also known as mobile calibration, is performed while the vehicle is in motion. This process requires clear weather, clear road lines, and controlled driving speeds. The advantage lies in its flexibility, as it tests the system in real-world conditions and requires less specific hardware. However, it relies significantly on weather and road conditions, and the performance can differ.

Choosing between these methods is based on automotive specifications, manufacturer specifications, and your service center's capacity. Frequently, both calibrations are required to ensure ideal ADAS performance, especially after services like windscreen changes or alignment services.

Each technique requires technical knowledge and should be approached with precision to ensure system integrity.

Diagnostic Procedures for Camera and Radar Systems

Modern ADAS vehicles require careful diagnostic procedures for camera and radar systems to ensure reliable functionality.

Begin with a visual inspection of sensors for obstructions and physical damage. It's crucial to check for system error codes that may indicate system malfunctions or misalignment. Confirm the placement of all components according to manufacturer specifications.
