ADAS & Contemporary Vehicle Systems

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

Stay current on most recent software updates and programming to ensure proper functioning of safety systems and adhere to warranty requirements.

Thorough documentation of these procedures is essential for meeting warranty requirements and effective safety system verification.

Static vs Dynamic Calibration Methods

An essential element of Advanced Driver Assistance Systems (ADAS) is guaranteeing precise calibration, which is achieved through either static or dynamic methods.

Static calibration is conducted with the vehicle immobile, typically in a specialized workspace like a workshop. The process demands a level surface, proper illumination, and specific calibration equipment. This method delivers high precision, but it requires a specialized facility and tends to be time-consuming. It's less adaptable and CloudBased Diagnostic Systems incurs higher facility costs but guarantees predictable performance, unaffected by weather.

On the other hand, dynamic calibration, or on-road calibration, occurs while the vehicle is being driven. This process requires clear weather, clear road lines, and controlled driving speeds. The advantage lies in its flexibility, as it tests the system in practical scenarios and demands less dedicated tools. However, it relies significantly on weather and road conditions, and the performance can differ.

Deciding between these methods is based on automotive specifications, manufacturer specifications, and your workshop's resources. Often, both calibrations are necessary to maintain ideal ADAS performance, specifically after services like windscreen changes or wheel alignments.

Each method requires technical knowledge and must be handled carefully to ensure system integrity.

ADAS Camera and Radar Diagnostics

Advanced driver assistance systems demand a meticulous approach to diagnosing sensing systems to guarantee optimal performance.

Initiate diagnostics with a visual inspection of sensors for obstructions and physical damage. You must retrieve any stored fault codes pointing to operational issues or alignment concerns. Confirm the placement of all components based on OEM requirements.
