Advanced Driver Assistance Systems and Modern Vehicle Technologies

When working on vehicles fitted with ADAS, you must complete both static and dynamic calibration for ensuring accurate camera and radar system diagnostics.

Stay informed on the latest programming and software updates to maintain proper functioning of vehicle safety features and comply with warranty guidelines.

Detailed recording of these processes remains critical 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 takes place with the vehicle at rest, often in a controlled setting like a workshop. You'll need a level surface, controlled lighting, and specific calibration equipment. This method provides high precision, but it requires a designated area and is often time-consuming. It's more rigid and requires substantial facility costs but guarantees consistent results, unaffected by weather.

Alternatively, dynamic calibration procedures, or on-road calibration, is performed while the vehicle is moving. This method requires clear weather, clear road lines, and controlled driving speeds. The advantage lies in its flexibility, as it assesses the system in actual driving situations and needs less specialized equipment. However, it relies significantly on weather and road conditions, and the outcomes may fluctuate.

Selecting from these methods depends on vehicle requirements, manufacturer specifications, and your workshop's resources. In many cases, both calibrations are essential to maintain ideal ADAS performance, especially after services like windscreen changes or wheel alignments.
