Comprehensive logging of these processes is crucial for warranty compliance and proper safety system verification.

Static vs Dynamic Calibration Methods

An essential element of driver assistance systems is maintaining precise calibration, which can be accomplished through two main methods.

Static calibration takes place with the vehicle at rest, often in a specialized workspace like a workshop. This requires a flat surface, proper illumination, and specific calibration equipment. This approach provides high precision, but it requires a dedicated workspace and can be time-consuming. It's more rigid and incurs higher facility costs but ensures consistent results, unaffected by weather.

Alternatively, dynamic calibration, or on-road calibration, takes place while the vehicle is moving. This process requires clear weather, clear road lines, and particular vehicle velocities. You'll benefit from its flexibility, as it evaluates the system in actual driving situations and needs less dedicated tools. However, it is greatly influenced by weather and road conditions, and the results can vary.

Deciding between these methods depends on vehicle requirements, OEM guidelines, and your service center's capacity. Often, both calibrations are necessary to ensure ideal ADAS performance, especially after services like windscreen changes or alignment services.

Each method demands technical knowledge and needs to be approached with precision to ensure system integrity.

ADAS Camera and Radar Diagnostics

Modern ADAS vehicles require a meticulous approach to diagnosing sensing systems to guarantee optimal performance.

Initiate diagnostics with examining sensors visually for obstructions and physical damage. Be sure to retrieve any stored fault codes that may indicate operational issues or alignment concerns. Confirm the placement of all components according to manufacturer specifications.
