ADAS & Contemporary Vehicle Technologies

For vehicles featuring ADAS systems, it's necessary to address both static and dynamic calibration to ensure precise system diagnostics for cameras and radar units.

Stay informed on newest software updates and programming to ensure the accuracy of safety systems and comply with warranty requirements.

Comprehensive logging of these procedures remains critical for meeting warranty requirements and proper safety system verification.

Dynamic vs Static Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is guaranteeing precise calibration, which is achieved through either static or dynamic methods.

Static calibration procedures is performed with the vehicle at rest, usually in a controlled setting like a workshop. This requires a flat surface, controlled lighting, and specific calibration equipment. This technique offers high precision, but it requires a dedicated workspace and can be time-consuming. It's more rigid and incurs higher facility costs but delivers consistent results, unaffected by weather.

Alternatively, dynamic calibration procedures, or on-road calibration, is performed while the vehicle is moving. This process needs clear weather, clear road lines, and specific driving speeds. This method offers its flexibility, as it evaluates the system in practical scenarios and needs less dedicated tools. However, it relies significantly on weather and road conditions, and the results can vary.

Deciding between these methods depends on specific vehicle needs, manufacturer specifications, and your workshop's resources. Frequently, both calibrations are essential to maintain ideal ADAS performance, particularly after services like windscreen changes or wheel balancing.

Each method needs professional expertise and needs to be handled carefully to ensure system integrity.

Camera and Radar System Diagnostics

Today's ADAS-equipped vehicles need a meticulous approach to diagnosing vision and radar components for reliable functionality.

Initiate diagnostics with checking all sensors for obstructions and physical damage. It's crucial to retrieve any stored fault codes that may indicate component issues or positioning problems. Confirm the placement of all components based on OEM requirements.
