Detailed recording of calibration steps remains critical for meeting warranty requirements and effective verification of safety systems.

Dynamic vs Static Calibration Methods

A key component of driver assistance systems is guaranteeing precise calibration, which is achieved through both static and dynamic methods.

The static calibration process is conducted with the vehicle stationary, usually in a specialized workspace like a workshop. You'll need a level surface, proper illumination, and specialized calibration tools. This technique offers high precision, but it necessitates a specialized facility and can be time-consuming. It's less flexible and involves greater facility costs but guarantees reliable outcomes, not influenced by weather.

In contrast, the dynamic method, or on-road calibration, takes place while the vehicle is in motion. This process demands clear weather, well-defined lane markers, and controlled driving speeds. You'll benefit from its flexibility, as it assesses the system in practical scenarios and needs less dedicated tools. However, it is greatly influenced by weather and road conditions, and the results can vary.

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

Each technique needs specialized skills and must be approached with precision to preserve system integrity.

ADAS Camera and Radar Diagnostics

Today's ADAS-equipped vehicles need careful diagnostic procedures for camera and radar systems to ensure optimal performance.

Start by conducting examining sensors visually for obstructions and physical damage. You must check for system error codes pointing to component issues or positioning problems. Verify sensor positioning following factory guidelines.
