Detailed recording of these processes is essential for meeting warranty requirements and effective verification of safety systems.

Comparing Static and Dynamic Calibration Methods

A crucial aspect of ADAS technology is ensuring precise calibration, which is performed through two main methods.

Static calibration procedures is performed with the vehicle stationary, usually in a specialized workspace like a workshop. You'll need a level surface, regulated lighting, and specialized calibration tools. This technique provides high precision, but it requires a specialized facility and tends to be time-consuming. It's more rigid and involves greater facility costs but delivers consistent results, not influenced by weather.

On the other hand, dynamic calibration procedures, also known as mobile calibration, is performed while the vehicle is moving. This approach requires clear weather, visible road markings, and particular vehicle velocities. The advantage lies in its flexibility, as it tests the system in real-world conditions and requires less dedicated tools. However, it is greatly influenced by weather and road conditions, and the performance can differ.

Choosing between these methods is based on vehicle requirements, manufacturer requirements, and your facility's capabilities. In many cases, both calibrations are essential to guarantee ideal ADAS performance, especially after services like windscreen changes or wheel balancing.

Each approach needs professional expertise and must be approached with precision to ensure system integrity.

ADAS Camera and Radar Diagnostics

Advanced driver assistance systems demand careful diagnostic procedures for camera and radar systems to ensure optimal performance.

Start by conducting a visual inspection of sensors to identify any blockages or damage. Be sure to scan for diagnostic trouble codes which could reveal system malfunctions or misalignment. Confirm sensor positioning based on OEM requirements.
