Dynamic vs Static Calibration Methods

A key component of ADAS technology is guaranteeing precise calibration, which is performed through two main methods.

Static calibration takes place with the vehicle stationary, typically in a controlled setting like a workshop. This requires a level surface, proper illumination, and specific calibration equipment. This technique offers high precision, but it necessitates a specialized facility and can be time-consuming. It's less adaptable and incurs higher facility costs but delivers predictable performance, not influenced by weather.

In contrast, dynamic calibration procedures, also known as mobile calibration, occurs while the vehicle is moving. This process needs clear weather, visible road markings, and particular vehicle velocities. The advantage lies in its flexibility, as it evaluates the system in real-world conditions and requires less specific hardware. However, it depends heavily on weather and road conditions, and the results can vary.

Choosing between these methods depends on vehicle requirements, OEM guidelines, and your service center's capacity. Often, both calibrations are necessary to ensure ideal ADAS performance, specifically after services like windscreen changes or wheel alignments.

Each approach requires specialized skills and must be executed precisely to preserve system integrity.

Diagnostic Procedures for Camera and Radar Systems

Advanced driver assistance systems demand a meticulous approach to diagnosing vision and radar components for flawless operation.

Start by conducting checking all sensors for damage or obstruction. It's crucial to check for system error codes pointing to system malfunctions or misalignment. Verify sensor positioning according to manufacturer specifications.
