Dynamic vs Static Calibration Methods

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

Static calibration is conducted with the vehicle immobile, often in a controlled environment like a workshop. The process demands a level surface, controlled lighting, and specialized calibration tools. This approach provides high precision, but it necessitates a dedicated workspace and tends to be time-consuming. It's more rigid and incurs higher facility costs but ensures consistent results, independent of weather.

In contrast, dynamic calibration procedures, or on-road calibration, is performed while the vehicle is being driven. This method needs clear weather, well-defined lane markers, and particular vehicle velocities. You'll benefit from its flexibility, as it assesses the system in real-world conditions and demands less specialized equipment. However, it depends heavily on weather and road conditions, and the performance can differ.

Deciding between these methods depends on specific vehicle needs, manufacturer requirements, and your facility's capabilities. In many cases, both calibrations are necessary to ensure ideal ADAS performance, particularly after services like glass installations or wheel balancing.

Each method requires professional expertise and must be handled carefully to ensure system integrity.

Camera and Radar System Diagnostics

Today's ADAS-equipped vehicles need careful diagnostic procedures for camera and radar systems to ensure reliable functionality.
