ADAS & Current Vehicle Technologies

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

Maintain awareness of newest software updates and programming to maintain precision of vehicle safety features and meet warranty guidelines.

Thorough documentation of calibration steps remains critical for warranty compliance and effective safety system verification.

Dynamic vs Static Calibration Methods

A key component of ADAS technology is maintaining precise calibration, which is performed through two main methods.

Static calibration takes place with the vehicle at rest, usually in a controlled setting like a workshop. You'll need a flat surface, regulated lighting, and professional calibration instruments. This approach offers high precision, but it requires a specialized facility and is often time-consuming. It's less adaptable and requires substantial facility costs but ensures predictable performance, independent of weather.

Alternatively, dynamic calibration, or on-road calibration, is performed while the vehicle is moving. This process needs clear weather, visible road markings, and controlled driving speeds. This method offers its flexibility, as it tests the system in real-world conditions and requires less specialized equipment. However, it is greatly influenced by weather and road conditions, and the outcomes may fluctuate.

Selecting from these methods hinges on vehicle requirements, manufacturer requirements, and your facility's capabilities. In many cases, both calibrations are essential to maintain ideal ADAS performance, particularly after services like glass installations or alignment services.

Each method needs specialized skills and must be executed precisely to maintain system integrity.

ADAS Camera and Radar Diagnostics

Today's ADAS-equipped vehicles need a meticulous approach to diagnosing sensing systems to guarantee reliable functionality.

Initiate diagnostics with examining sensors visually to identify any blockages or damage. You must retrieve any stored fault codes which could reveal system malfunctions or misalignment. Check the placement of all components following factory guidelines.
