Dynamic vs Static Calibration Methods

An essential element of Advanced Driver Assistance Systems (ADAS) is guaranteeing precise calibration, which can be accomplished through both static and dynamic methods.

Static calibration procedures takes place with the vehicle at rest, often in a controlled setting like a workshop. This requires a level floor, controlled lighting, and specialized calibration tools. This method provides high precision, but it requires a specialized facility and tends to be time-consuming. It's less flexible and incurs higher facility costs but delivers reliable outcomes, unaffected by weather.

On the other hand, the dynamic method, or on-road calibration, takes place while the vehicle is moving. This method demands clear weather, well-defined lane markers, and specific driving speeds. You'll benefit from its flexibility, as it evaluates the system in practical scenarios and demands less dedicated tools. However, it is greatly influenced by weather and road conditions, and the results can vary.

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

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

ADAS Camera and Radar Diagnostics

Today's ADAS-equipped vehicles need careful diagnostic procedures for vision and radar components for reliable functionality.

Start by conducting examining sensors visually for damage or obstruction. You must scan for diagnostic trouble codes which could reveal component issues or positioning problems. Confirm each component's positioning based on OEM requirements.
