ADAS and Contemporary Vehicle Systems

When working on vehicles fitted with ADAS, technicians need to perform both dynamic and static calibration to guarantee accurate system diagnostics for cameras and radar units.

Maintain awareness of newest software updates and programming to ensure proper functioning of vehicle safety features and comply with warranty guidelines.

Comprehensive logging of calibration steps remains critical for meeting warranty requirements and reliable verification of safety systems.

Static vs Dynamic Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is maintaining precise calibration, which is performed through two main methods.

The static calibration process takes place with the vehicle at rest, typically in a specialized workspace like a workshop. The process demands a level surface, proper illumination, and specialized calibration tools. This approach delivers high precision, but it requires a specialized facility and is often time-consuming. It's less adaptable and incurs higher facility costs but ensures reliable outcomes, not influenced by weather.

On the other hand, the dynamic method, or on-road calibration, occurs while the vehicle is being driven. This process requires clear weather, clear road lines, and specific driving speeds. This method offers its flexibility, as it evaluates the system in actual driving situations and needs less specialized equipment. However, it is greatly influenced by weather and road conditions, and the outcomes may fluctuate.

Deciding between these methods is based on vehicle requirements, manufacturer specifications, and your service center's capacity. Often, both calibrations are necessary to maintain ideal ADAS performance, especially after services like glass installations or alignment services.
