Static vs Dynamic Calibration Methods

An essential element of driver assistance systems is maintaining precise calibration, which is achieved through both static and dynamic methods.

Static calibration procedures is conducted with the vehicle stationary, usually in a controlled environment like a workshop. The process demands a flat surface, controlled lighting, and professional calibration instruments. This method provides high precision, but it necessitates a designated area and is often time-consuming. It's less flexible and involves greater facility costs but delivers consistent results, independent of weather.

Alternatively, the dynamic method, also known as mobile calibration, is performed while the vehicle is being driven. This approach needs clear weather, well-defined lane markers, and particular vehicle velocities. You'll benefit from its flexibility, as it tests the system in practical scenarios and requires less dedicated tools. However, it is greatly influenced by weather and road conditions, and the results can vary.

Deciding between these methods is based on automotive specifications, manufacturer requirements, and your workshop's resources. Frequently, both calibrations are required to maintain ideal ADAS performance, especially after services like glass installations or wheel alignments.

Each approach demands professional expertise and should be approached with precision to preserve system integrity.

Camera and Radar System Diagnostics

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

Start by conducting checking all sensors to identify any blockages or damage. Be sure to check for system error codes that may indicate system malfunctions or misalignment. Confirm each component's positioning according to manufacturer specifications.
