Advanced Driver Assistance Systems and Modern Vehicle Technologies

When servicing vehicles equipped with ADAS, it's necessary to address both static and dynamic calibration for ensuring precise camera and radar system diagnostics.

Maintain awareness of most recent software updates and programming to preserve the accuracy of safety systems and comply with warranty requirements.

Detailed recording of calibration steps is essential for meeting warranty requirements and effective verification of safety systems.

Static vs Dynamic Calibration Methods

An essential element of ADAS technology is guaranteeing precise calibration, which is achieved through two main methods.

Static calibration procedures is performed with the vehicle immobile, usually in a controlled setting like a workshop. You'll need a flat surface, regulated lighting, and professional calibration instruments. This technique provides high precision, but it requires a dedicated workspace and can be time-consuming. It's less adaptable and requires substantial facility costs but delivers consistent results, unaffected by weather.

Alternatively, dynamic calibration procedures, also known as mobile calibration, is performed while the vehicle is moving. This approach requires clear weather, clear road lines, and controlled driving speeds. The advantage lies in its flexibility, as it tests the system in practical scenarios and demands less specific hardware. However, it depends heavily on weather and road conditions, and the performance can differ.

Selecting from these methods is based on vehicle requirements, manufacturer specifications, and your workshop's resources. Often, both calibrations are required to maintain ideal ADAS performance, especially after services like windshield replacements or wheel alignments.
