ADAS & Current Vehicle Systems

When repairing vehicles equipped with ADAS, you must perform both dynamic and static calibration to guarantee accurate system diagnostics for cameras and radar units.

Keep track of most recent programming and software updates to preserve the accuracy of safety systems and adhere to warranty requirements.

Thorough documentation of calibration steps is crucial for warranty compliance and reliable verification of safety systems.

Dynamic vs Static Calibration Methods

A key component of driver assistance systems is guaranteeing precise calibration, which is achieved through two main methods.

The static calibration process is performed with the vehicle at rest, typically in a specialized workspace like a workshop. This requires a level surface, controlled lighting, and specialized calibration tools. This method offers high precision, but it necessitates a specialized facility and is often time-consuming. It's more rigid and involves greater facility costs but guarantees reliable outcomes, not influenced by weather.

In contrast, dynamic calibration, also known as mobile calibration, is performed while the vehicle is in motion. This approach needs clear weather, clear road lines, and specific driving speeds. This method offers its flexibility, as it tests the system in practical scenarios and needs less specialized equipment. However, it is greatly influenced by weather and road conditions, and the results can vary.

Choosing between these methods is based on automotive specifications, manufacturer specifications, and your service center's capacity. In many cases, both calibrations are required to maintain ideal ADAS performance, specifically after services like glass installations or wheel alignments.

Each technique demands specialized skills and needs to be handled carefully to ensure system integrity.

ADAS Camera and Radar Diagnostics

Modern ADAS vehicles require a meticulous approach to diagnosing vision and radar components for flawless operation.

Begin with a visual inspection of sensors for obstructions and physical damage. You must retrieve any stored fault codes that may indicate component issues or positioning problems. Confirm the placement of all components based on OEM requirements.

Vision systems are essential for identifying road elements and markings, despite having some restrictions. Challenging environmental conditions may reduce effectiveness, and compromised visibility conditions can hinder operation. Manage these challenges with systematic cleaning procedures.
