Dynamic vs Static Calibration Methods

An essential element of driver assistance systems is ensuring precise calibration, which is achieved through both static and dynamic methods.

The static calibration process is performed with the vehicle at rest, typically in a specialized workspace like a workshop. This requires a flat surface, regulated lighting, and professional calibration instruments. This method provides high precision, but it necessitates a designated area and can be time-consuming. It's less flexible and involves greater facility costs but guarantees predictable performance, not influenced by weather.

In contrast, dynamic calibration, or on-road calibration, occurs while the vehicle is in motion. This method demands clear weather, clear road lines, and particular vehicle velocities. This method offers its flexibility, as it assesses the system in real-world conditions and needs less specialized equipment. However, it is greatly influenced by weather and road conditions, and the performance can differ.

Selecting from these methods depends on automotive specifications, OEM guidelines, and your service center's capacity. In many cases, both calibrations are necessary to ensure ideal ADAS performance, especially after services like windscreen changes or alignment services.

Each method demands professional expertise and should be handled carefully to maintain system integrity.

Diagnostic Procedures for Camera and Radar Systems

Today's ADAS-equipped vehicles need a meticulous approach to diagnosing camera and radar systems to ensure optimal performance.
