Static vs. Dynamic ADAS Calibration

Whenever an ADAS (advanced driver-assistance system) sensor is damaged, moved or disrupted in any way, it needs to be calibrated. Every manufacturer has different requirements and repair processes, but they all require a proper calibration to ensure that driver-assistance features will function correctly and safely after disruption. There are two basic types of calibration you can perform: static or dynamic. The type you choose will depend on the recommended OEM repair procedures for that make and model.

What is static calibration?
Static calibration happens inside a shop while the vehicle is parked in place. The first step is finding the thrust line and setting up the vehicle in front of the ADAS tool you’ll use to complete the calibration. All ADAS tools use a series of targets (specific to OEM standards) that the sensors must be able to read in order to accurately recalibrate. It’s important that the vehicle is the correct distance away from the targets and that the targets are at the proper height, among other things. Different ADAS tools will have their own setup methods, but it’s important that this step is done correctly every time in order to ensure an accurate result.

What is dynamic calibration?
Dynamic calibration is also referred to as on-road calibration because the bulk of the work is done while driving the vehicle. Just like the static calibration process, dynamic calibration starts in the shop using a diagnostic tool to uncover which ADAS features have been disrupted. Then, depending on whether you’re calibrating a camera, radar or other sensor type, you would move to dynamic calibration to complete the process. This is because only certain types of sensors require the vehicle to be in motion in order to accurately reset the feature. Cameras typically require driving on a straight road between five and 30 minutes at certain speeds. The road should have visible and clear lane markings to help the cameras detect the vehicle’s position in the lane. Some systems actually calibrate better when surrounded by traffic, while others work best on an empty road.

With any ADAS repair procedure, the first step is checking your process against OEM recommendations. It helps to have an ADAS calibration tool that makes outlining the repair process automated and easy to follow.
