ADAS & Contemporary Vehicle Technologies

When working on vehicles fitted with ADAS, it's necessary to complete both static and dynamic calibration to guarantee precise camera and radar system diagnostics.

Maintain awareness of the latest programming and software updates to maintain precision of vehicle safety features and comply with warranty guidelines.

Detailed recording of calibration steps is crucial for meeting warranty requirements and reliable verification of safety systems.

Comparing Static and Dynamic Calibration Methods

An essential element of driver assistance systems is maintaining precise calibration, which is performed through two main methods.

Static calibration procedures takes place with the vehicle at rest, typically in a controlled environment like a workshop. The process demands a flat surface, controlled lighting, and professional calibration instruments. This technique delivers high precision, but it demands a designated area and tends to be time-consuming. It's less flexible and requires substantial facility costs but delivers consistent results, independent of weather.

In contrast, the dynamic method, or on-road calibration, occurs while the vehicle is being driven. This method demands clear weather, visible road markings, and particular vehicle velocities. This method offers its flexibility, as it evaluates the system in actual driving situations and requires 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, manufacturer specifications, and your service center's capacity. Frequently, both calibrations are essential to ensure ideal ADAS performance, particularly after services like windscreen changes or alignment services.

Each method needs technical knowledge and needs to be handled carefully to preserve system integrity.

Camera and Radar System Diagnostics

Modern ADAS vehicles require thorough assessment of vision and radar components for reliable functionality.

Begin with checking all sensors for obstructions and physical damage. You must check for system error codes that may indicate system malfunctions or misalignment. Verify each component's positioning based on OEM requirements.
