Comparing Static and Dynamic Calibration Methods
A crucial aspect of Advanced Driver Assistance Systems (ADAS) is guaranteeing precise calibration, which can be accomplished through two main methods.
Static calibration procedures takes place with the vehicle stationary, usually in a controlled environment like a workshop. This requires a level floor, controlled lighting, and professional calibration instruments. This technique provides high precision, but it demands a dedicated workspace and can be time-consuming. It's more rigid and requires substantial facility costs but ensures reliable outcomes, not influenced by weather.
In contrast, dynamic calibration procedures, or on-road calibration, takes place while the vehicle is moving. This approach demands clear weather, visible road markings, and controlled driving speeds. The advantage lies in its flexibility, as it assesses the system in real-world conditions and requires less dedicated tools. However, it depends heavily on weather and road conditions, and the performance can differ.
Deciding between these methods is based on automotive specifications, manufacturer specifications, and your workshop's resources. In many cases, both calibrations are essential to guarantee ideal ADAS performance, especially after services like glass installations or wheel balancing.
Each technique requires professional expertise and must be handled carefully to ensure system integrity.
Camera and Radar System Diagnostics
Today's ADAS-equipped vehicles need thorough assessment of sensing systems to guarantee optimal performance.
