When repairing vehicles equipped with ADAS, it's necessary to complete both dynamic and static calibration to ensure precise system diagnostics for cameras and radar units.

Keep track of newest programming and software updates to maintain proper functioning of safety systems and comply with warranty requirements.

Thorough documentation of calibration steps is crucial for warranty compliance and proper safety system verification.

Dynamic vs Static Calibration Methods

An essential element of ADAS technology is ensuring 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. You'll need a level surface, regulated lighting, and professional calibration instruments. This approach provides high precision, but it demands a designated area and tends to be time-consuming. It's less adaptable and involves greater facility costs but delivers reliable outcomes, independent of weather.

In contrast, dynamic calibration procedures, or on-road calibration, is performed while the vehicle is moving. This process needs clear weather, well-defined lane markers, and particular vehicle velocities. This method offers its flexibility, as it tests the system in real-world conditions and requires less specific hardware. However, it is greatly influenced by weather and road conditions, and the outcomes may fluctuate.

Deciding between these methods hinges on specific vehicle needs, manufacturer specifications, and your service center's capacity. Often, both calibrations are required to maintain ideal ADAS performance, especially after services like windscreen changes or wheel alignments.

Each approach needs technical knowledge and needs to be executed precisely to maintain system integrity.

ADAS Camera and Radar Diagnostics

Advanced driver assistance systems demand careful diagnostic procedures for vision and radar components for flawless operation.
