ADAS & Modern Vehicle Technologies

For vehicles featuring ADAS systems, you must perform both static and dynamic calibration to guarantee precise camera and radar system diagnostics.

Maintain awareness of the latest programming and software updates to preserve precision of safety systems and adhere to warranty requirements.

Thorough documentation of these processes is crucial for warranty compliance and reliable safety system verification.

Static vs Dynamic Calibration Methods

A crucial aspect of driver assistance systems is guaranteeing precise calibration, which is achieved through two main methods.

Static calibration is performed with the vehicle immobile, usually in a specialized workspace like a workshop. You'll need a level floor, controlled lighting, and professional calibration instruments. This technique delivers high precision, but it demands a specialized facility and tends to be time-consuming. It's more rigid and requires substantial facility costs but guarantees predictable performance, unaffected by weather.

On the other hand, dynamic calibration, or on-road calibration, occurs while the vehicle is being driven. This process requires clear weather, well-defined lane markers, and specific driving speeds. You'll benefit from its flexibility, as it assesses the system in practical scenarios and requires less specific hardware. However, it relies significantly on weather and road conditions, and the results can vary.

Selecting from these methods is based on automotive specifications, manufacturer specifications, and your service center's capacity. Often, both calibrations are necessary to ensure ideal ADAS performance, specifically after services like windscreen changes or alignment services.

Each approach demands professional expertise and must be executed precisely to maintain system integrity.

Camera and Radar System Diagnostics
