Advanced Driver Assistance Systems & Current Vehicle Systems

For vehicles featuring ADAS systems, you must address both static and dynamic calibration to ensure precise system diagnostics for cameras and radar units.

Keep track of newest software updates and programming to preserve the accuracy of vehicle safety features and comply with warranty requirements.

Detailed recording of calibration steps remains critical for warranty compliance and reliable verification of safety systems.

Comparing Static and Dynamic Calibration Methods

A crucial aspect of ADAS technology is maintaining precise calibration, which is achieved through two main methods.

Static calibration is performed with the vehicle at rest, often in a controlled environment like a workshop. You'll need a level floor, regulated lighting, and specialized calibration tools. This technique provides high precision, but it requires a designated area and can be time-consuming. It's less flexible and incurs higher facility costs but ensures consistent results, independent of weather.

Alternatively, the dynamic method, or on-road calibration, is performed while the vehicle is moving. This approach demands clear weather, well-defined lane markers, and particular vehicle velocities. The advantage lies in its flexibility, as it evaluates the system in actual driving situations and demands less specific hardware. However, it is greatly influenced by weather and road conditions, and the outcomes may fluctuate.

Selecting from these methods depends on specific vehicle needs, OEM guidelines, and your service center's capacity. Frequently, both calibrations are required to ensure ideal ADAS performance, particularly after services like windscreen changes or alignment services.
