ADAS and Modern Vehicle Systems

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

Stay informed on the latest programming and software updates to maintain the accuracy of safety systems and comply with warranty specifications.

Detailed recording of these procedures is essential for meeting warranty requirements and reliable verification of safety systems.

Dynamic vs Static Calibration Methods

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

Static calibration is conducted with the vehicle at rest, often in a controlled environment like a workshop. The process demands a level floor, controlled lighting, and specialized calibration tools. This approach offers high precision, but it necessitates a dedicated workspace and tends to be time-consuming. It's more rigid and requires substantial facility costs but delivers consistent results, not influenced by weather.

Alternatively, the dynamic method, also known as mobile calibration, occurs while the vehicle is moving. This approach requires clear weather, visible road markings, and particular vehicle velocities. This method offers its flexibility, as it assesses the system in real-world conditions and requires less specialized equipment. However, it depends heavily on weather and road conditions, and the performance can differ.

Choosing between these methods is based on automotive specifications, manufacturer requirements, and your workshop's resources. Often, both calibrations are essential to ensure ideal ADAS performance, especially after services like glass installations or wheel balancing.
