ADAS & Current Vehicle Technologies

For vehicles featuring ADAS systems, it's necessary to perform both static and dynamic calibration to ensure accurate camera and radar system diagnostics.

Maintain awareness of the latest software updates and programming to ensure the accuracy of vehicle safety features and adhere to warranty specifications.

Thorough documentation of these procedures remains critical for warranty compliance and reliable safety system verification.

Dynamic vs Static Calibration Methods

A key component of Advanced Driver Assistance Systems (ADAS) is guaranteeing precise calibration, which is performed through two main methods.

Static calibration procedures is performed with the vehicle stationary, often in a controlled setting like a workshop. You'll need a flat surface, regulated lighting, and specific calibration equipment. This method delivers high precision, but it demands a designated area and is often time-consuming. It's less adaptable and involves greater facility costs but delivers reliable outcomes, independent of weather.

On the other hand, dynamic calibration, or mobile calibration, occurs while the vehicle is moving. This process demands clear weather, well-defined lane markers, and specific driving speeds. This method offers its flexibility, as it tests the system in real-world conditions and needs less dedicated tools. However, it relies significantly on weather and road conditions, and the performance can differ.

Selecting from these methods is based on vehicle requirements, manufacturer requirements, and your facility's capabilities. Often, both calibrations are essential to ensure ideal ADAS performance, particularly after services like windscreen changes or alignment services.

Each technique needs professional expertise and must be handled carefully to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems

Advanced driver assistance systems demand thorough assessment of sensing systems to guarantee optimal performance.
