ADAS & Contemporary Vehicle Technologies

For vehicles featuring ADAS systems, technicians need to complete both static and dynamic calibration to ensure precise camera and radar system diagnostics.

Maintain awareness of most recent programming and software updates to ensure precision of vehicle safety features and meet warranty specifications.

Comprehensive logging of these procedures remains critical for meeting warranty requirements and effective verification of safety systems.

Comparing Static and Dynamic Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is guaranteeing precise calibration, which can be accomplished through two main methods.

Static calibration procedures is conducted with the vehicle stationary, often in a controlled environment like a workshop. You'll need a level floor, regulated lighting, and specific calibration equipment. This approach offers high precision, but it requires a designated area and is often time-consuming. It's more rigid and incurs higher facility costs but guarantees predictable performance, unaffected by weather.

On the other hand, dynamic calibration procedures, or mobile calibration, is performed while the vehicle is in motion. This process demands clear weather, clear road lines, and controlled driving speeds. This method offers its flexibility, as it tests the system in actual driving situations and needs less specific hardware. However, it relies significantly on weather and road conditions, and the results can vary.

Selecting from these methods hinges on vehicle requirements, manufacturer specifications, and your workshop's resources. Frequently, both calibrations are necessary to ensure ideal ADAS performance, especially after services like glass installations or wheel alignments.

Each approach needs professional expertise and must be approached with precision to preserve system integrity.

ADAS Camera and Radar Diagnostics
