ADAS & Current Vehicle Systems
For vehicles featuring ADAS systems, technicians need to perform both static and dynamic calibration to guarantee precise camera and radar system diagnostics.
Stay current on most recent programming and software updates to ensure precision of safety systems and adhere to warranty requirements.
Comprehensive logging of calibration steps is essential for warranty compliance and effective safety system verification.
Static vs Dynamic Calibration Methods
A crucial aspect of ADAS technology is guaranteeing precise calibration, which is achieved through two main methods.
Static calibration procedures is performed with the vehicle at rest, often in a specialized workspace like a workshop. This requires a level surface, regulated lighting, and professional calibration instruments. This approach delivers high precision, but it requires a specialized facility and is often time-consuming. It's less adaptable and incurs higher facility costs but delivers predictable performance, unaffected by weather.
Alternatively, dynamic calibration procedures, also known as mobile calibration, takes place while the vehicle is in motion. This approach requires clear weather, well-defined lane markers, and controlled driving speeds. The advantage lies in its flexibility, as it tests the system in practical scenarios and requires less specialized equipment. However, it is greatly influenced by weather and road conditions, and the outcomes may fluctuate.
Choosing between these methods is based on vehicle requirements, manufacturer specifications, and your service center's capacity. Frequently, both calibrations are essential to maintain ideal ADAS performance, especially after services like windscreen changes or wheel alignments.
Each technique requires specialized skills and needs to be executed precisely to ensure system integrity.
ADAS Camera and Radar Diagnostics
Today's ADAS-equipped vehicles need careful diagnostic procedures for camera and radar systems to ensure flawless operation.
Start by conducting a visual inspection of sensors to identify any blockages or damage. You must check for system error codes pointing to component issues or positioning problems. Check sensor positioning based on OEM requirements.
