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

Maintain awareness of most recent software updates and programming to ensure proper functioning of vehicle safety features and comply with warranty guidelines.

Thorough documentation of these processes is essential for warranty compliance and proper verification of safety systems.

Static vs Dynamic Calibration Methods

A crucial aspect of ADAS technology is guaranteeing precise calibration, which can be accomplished through either static or dynamic methods.

Static calibration is conducted with the vehicle immobile, typically in a controlled setting like a workshop. The process demands a level floor, controlled lighting, and professional calibration instruments. This technique delivers high precision, but it requires a designated area and can be time-consuming. It's more rigid and involves greater facility costs but delivers consistent results, not influenced by weather.

In contrast, dynamic calibration procedures, also known as mobile calibration, takes place while the vehicle is in motion. This method needs clear weather, clear road lines, and particular vehicle velocities. The advantage lies in its flexibility, as it assesses the system in real-world conditions and needs less specialized equipment. However, it relies significantly on weather and road conditions, and the outcomes may fluctuate.

Selecting from these methods hinges on specific vehicle needs, OEM guidelines, and your facility's capabilities. Often, both calibrations are essential to guarantee ideal ADAS performance, especially after services like windshield replacements or wheel balancing.

Each approach needs technical knowledge and needs to be handled carefully to maintain system integrity.
