Dynamic vs Static Calibration Methods

A key component of driver assistance systems is ensuring precise calibration, which is performed through either static or dynamic methods.

Static calibration procedures is performed with the vehicle at rest, often in a controlled setting like a workshop. This requires a level surface, controlled lighting, and professional calibration instruments. This technique provides high precision, but it necessitates a dedicated workspace and can be time-consuming. It's less adaptable and incurs higher facility costs but delivers consistent results, independent of weather.

In contrast, dynamic calibration procedures, also known as mobile calibration, is performed while the vehicle is being driven. This approach needs clear weather, visible road markings, and specific driving speeds. The advantage lies in its flexibility, as it assesses the system in practical scenarios and needs less dedicated tools. However, it relies significantly on weather and road conditions, and the performance can differ.

Deciding between these methods is based on automotive specifications, OEM guidelines, and your facility's capabilities. Often, both calibrations are essential to maintain ideal ADAS performance, particularly after services like glass installations or wheel balancing.

Each approach needs professional expertise and should be approached with precision to preserve system integrity.

Diagnostic Procedures for Camera and Radar Systems

Advanced driver assistance systems demand a meticulous approach to diagnosing camera and radar systems to ensure reliable functionality.

Begin with a visual inspection of sensors for damage or obstruction. It's crucial to retrieve any stored fault codes which could reveal component issues or positioning problems. Check the placement of all components following factory guidelines.
