Thorough documentation of calibration steps is crucial for meeting warranty requirements and effective verification of safety systems.

Static vs Dynamic Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is ensuring precise calibration, which can be accomplished through both static and dynamic methods.

Static calibration procedures takes place with the vehicle stationary, usually in a specialized workspace like a workshop. You'll need a flat surface, regulated lighting, and specific calibration equipment. This technique provides high precision, but it demands a dedicated workspace and is often time-consuming. It's less adaptable and involves greater facility costs but delivers predictable performance, not influenced by weather.

On the other hand, dynamic calibration, or mobile calibration, is performed while the vehicle is being driven. This approach demands clear weather, well-defined lane markers, and controlled driving speeds. The advantage lies in its flexibility, as it tests the system in practical scenarios and needs less dedicated tools. However, it relies significantly on weather and road conditions, and the performance can differ.

Choosing between these methods hinges on vehicle requirements, manufacturer specifications, and your workshop's resources. Often, both calibrations are essential to maintain ideal ADAS performance, especially after services like windscreen changes or wheel balancing.

Each approach demands technical knowledge and should be approached with precision to preserve system integrity.

Camera and Radar System Diagnostics

Modern ADAS vehicles require a meticulous approach to diagnosing vision and radar components for optimal performance.
