Dynamic vs Static Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is ensuring precise calibration, which is achieved through both static and dynamic methods.

Static calibration procedures takes place with the vehicle immobile, usually in a controlled setting like a workshop. This requires a level floor, proper illumination, and professional calibration instruments. This method offers high precision, but it requires a designated area and is often time-consuming. It's less adaptable and requires substantial facility costs but guarantees predictable performance, not influenced by weather.

On the other hand, dynamic calibration, or on-road calibration, is performed while the vehicle is being driven. This approach needs clear weather, visible road markings, and particular vehicle velocities. The advantage lies in its flexibility, as it tests the system in actual driving situations and requires less specialized equipment. However, it is greatly influenced by weather and road conditions, and the results can vary.

Deciding between these methods depends on vehicle requirements, OEM guidelines, and your workshop's resources. In many cases, both calibrations are necessary to maintain ideal ADAS performance, particularly after services like windshield replacements or wheel balancing.

Each approach needs professional expertise and must be executed precisely to preserve system integrity.

ADAS Camera and Radar Diagnostics

Today's ADAS-equipped vehicles need a meticulous approach to diagnosing camera and radar systems to ensure flawless operation.

Start by conducting a visual inspection of sensors to identify any blockages or damage. Be sure to scan for diagnostic trouble codes that may indicate component issues or positioning problems. Check the placement of all components according to manufacturer specifications.
