Advanced Driver Assistance Systems & Current Vehicle Systems

For vehicles featuring ADAS systems, it's necessary to complete both dynamic and static calibration to guarantee exact camera and radar system diagnostics.

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

Comprehensive logging of calibration steps remains critical for warranty compliance and reliable verification of safety systems.

Static vs Dynamic Calibration Methods

A key component of ADAS technology is maintaining precise calibration, which can be accomplished through two main methods.

Static calibration procedures takes place with the vehicle at rest, typically in a controlled environment like a workshop. This requires a flat surface, proper illumination, and specialized calibration tools. This approach delivers high precision, but it demands a designated area and can be time-consuming. It's more rigid and involves greater facility costs but ensures consistent results, unaffected by weather.

Alternatively, dynamic calibration procedures, or on-road calibration, is performed while the vehicle is being driven. This approach requires clear weather, clear road lines, and specific driving speeds. This method offers its flexibility, as it assesses 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.

Choosing between these methods depends on automotive specifications, manufacturer requirements, and your service center's capacity. In many cases, both calibrations are necessary to ensure ideal ADAS performance, specifically after services like glass installations or wheel balancing.

Each approach requires technical knowledge and needs to be approached with precision to preserve system integrity.

ADAS Camera and Radar Diagnostics

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

Initiate diagnostics with checking all sensors for damage or obstruction. You must check for system error codes which could reveal operational issues or alignment concerns. Confirm each component's positioning based on OEM requirements.
