ADAS & Contemporary Vehicle Technologies

For vehicles featuring ADAS systems, it's necessary to complete both static and dynamic calibration to guarantee accurate system diagnostics for cameras and radar units.

Keep track of the latest software updates and programming to preserve proper functioning of vehicle safety features and adhere to warranty specifications.

Thorough documentation of calibration steps remains critical for warranty compliance and reliable verification of safety systems.

Static vs Dynamic Calibration Methods

A crucial aspect of driver assistance systems is ensuring precise calibration, which can be accomplished through two main methods.

The static calibration process is conducted with the vehicle immobile, typically in a controlled environment like a workshop. This requires a level floor, 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 flexible and involves greater facility costs but guarantees predictable performance, not influenced by weather.

On the other hand, the dynamic method, or mobile calibration, takes place while the vehicle is being driven. This approach requires clear weather, clear road lines, and controlled driving speeds. The advantage lies in its flexibility, as it assesses the system in practical scenarios and demands less dedicated tools. However, it depends heavily on weather and road conditions, and the performance can differ.

Choosing between these methods is based on specific vehicle needs, OEM guidelines, and your facility's capabilities. Often, both calibrations are essential to ensure ideal ADAS performance, especially after services like windscreen changes or wheel balancing.

Each approach requires professional expertise and must be handled carefully to preserve system integrity.

ADAS Camera and Radar Diagnostics

Modern ADAS vehicles require a meticulous approach to diagnosing camera and radar systems to ensure reliable functionality.

Begin with examining sensors visually to identify any blockages or damage. You must scan for diagnostic trouble codes that may indicate system malfunctions or misalignment. Verify each component's positioning following factory guidelines.
