ADAS & Contemporary Vehicle Technologies

For vehicles featuring ADAS systems, technicians need to address both dynamic and static calibration for ensuring accurate system diagnostics for cameras and radar units.

Keep track of the latest programming and software updates to ensure precision of vehicle safety features and comply with warranty specifications.

Comprehensive logging of calibration steps is crucial for meeting warranty requirements and reliable safety system verification.

Static vs Dynamic Calibration Methods

A crucial aspect of driver assistance systems is ensuring precise calibration, which can be accomplished through two main methods.

Static calibration takes place with the vehicle at rest, typically in a controlled environment like a workshop. The process demands a level floor, regulated lighting, and specialized calibration tools. This approach delivers high precision, but it requires a dedicated workspace and is often time-consuming. It's less adaptable and involves greater facility costs but ensures reliable outcomes, independent of weather.

Alternatively, the dynamic method, or mobile calibration, occurs while the vehicle is being driven. This method needs clear weather, well-defined lane markers, and controlled driving speeds. This method offers its flexibility, as it tests the system in practical scenarios and demands less specialized equipment. However, it is greatly influenced by weather and road conditions, and the performance can differ.

Selecting from these methods is based on specific vehicle needs, manufacturer specifications, and your service center's capacity. In many cases, both calibrations are required to maintain ideal ADAS performance, particularly after services like windscreen changes or wheel balancing.

Each approach demands technical knowledge and should be approached with precision to preserve system integrity.

Camera and Radar System Diagnostics

Modern ADAS vehicles require a meticulous approach to diagnosing vision and radar components for flawless operation.

Start by conducting a visual inspection of sensors for obstructions and physical damage. You must retrieve any stored fault codes that may indicate operational issues or alignment concerns. Verify sensor positioning according to manufacturer specifications.
