ADAS and Contemporary Vehicle Technologies

When repairing vehicles fitted with ADAS, technicians need to complete both dynamic and static calibration to guarantee precise camera and radar system diagnostics.

Stay current on most recent software updates and programming to preserve precision of safety systems and adhere to warranty guidelines.

Detailed recording of these procedures is essential for warranty compliance and proper safety system verification.

Static vs Dynamic Calibration Methods

A key component of driver assistance systems is maintaining precise calibration, which can be accomplished through two main methods.

Static calibration procedures is performed with the vehicle stationary, typically in a controlled setting like a workshop. The process demands a level surface, proper illumination, and specialized calibration tools. This technique offers high precision, but it necessitates a designated area and tends to be time-consuming. It's less adaptable and involves greater facility costs but ensures reliable outcomes, unaffected by weather.

In contrast, dynamic calibration procedures, also known as mobile calibration, is performed while the vehicle is being driven. This process demands clear weather, clear road lines, and specific driving speeds. The advantage lies in its flexibility, as it evaluates the system in practical scenarios and requires less dedicated tools. However, it relies significantly on weather and road conditions, and the results can vary.

Choosing between these methods hinges on automotive specifications, manufacturer specifications, and your facility's capabilities. In many cases, both calibrations are essential to ensure ideal ADAS performance, specifically after services like windscreen changes or alignment services.

Each technique demands specialized skills and needs to be executed precisely to maintain system integrity.

Camera and Radar System Diagnostics

Modern ADAS vehicles require careful diagnostic procedures for vision and radar components for optimal performance.
