Technical Service Bulletin (TSB) Integration

Advanced Driver Assistance Systems & Contemporary Vehicle Technologies

When servicing vehicles fitted with ADAS, you must address both dynamic and static calibration to ensure accurate system diagnostics for cameras and radar units.

Keep track of newest programming and software updates to maintain precision of vehicle safety features and adhere to warranty guidelines.

Comprehensive logging of these processes is crucial for warranty compliance and reliable verification of safety systems.

Static vs Dynamic Calibration Methods

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

The static calibration process is conducted with the vehicle immobile, typically in a specialized workspace like a workshop. This requires a level floor, proper illumination, and specialized calibration tools. This method offers high precision, but it requires a designated area and can be time-consuming. It's less adaptable and involves greater facility costs but delivers consistent results, not influenced by weather.

In contrast, dynamic calibration, also known as mobile calibration, takes place while the vehicle is moving. This method requires clear weather, well-defined lane markers, and specific driving speeds. The advantage lies in its flexibility, as it tests the system in real-world conditions and requires less specific hardware. However, it depends heavily on weather and road conditions, and the outcomes may fluctuate.

Selecting from these methods hinges on automotive specifications, OEM guidelines, and your facility's capabilities. Often, both calibrations are essential to maintain ideal ADAS performance, especially after services like glass installations or wheel balancing.

Each method needs technical knowledge and must be handled carefully to maintain system integrity.
