The Difference Between Static and Dynamic ADAS Calibration

ADAS or Advanced Driver Assistance System is a wide-ranging set of features found in many modern cars. You might not be familiar with the term, but you are sure to be familiar with some of the features that make up ADAS. The purpose of many of these features is to improve road safety, and as such it is important to periodically check on the health and accuracy of the system. This involves having ADAS recalibrated by trained professionals using specialised equipment; it must happen whenever you have your windscreen replaced, but depending on your vehicle manufacturer’s recommendations, it could also be necessary whenever you change or replace tyres, have your wheels realigned, and whenever you have any work done affecting your vehicle’s suspension.

There are two types of ADAS calibration: dynamic (or mobile) and static. Before we look at the difference between dynamic and static ADAS calibration, let’s first look at some of the features that make up ADAS.

ADAS Features

As noted earlier, ADAS consists of a wide-ranging set of features that will vary from one vehicle model to another, with some models only having basic features, and others including state-of-the-art features. Common features include:

  • Adaptive cruise control (ACC)
  • Adaptive head lights
  • Adaptive light control
  • Autonomous emergency braking (AEB)
  • Automatic braking systems (ABS)
  • Blind spot monitoring
  • Collision avoidance systems
  • Forward collision warning
  • Intelligent speed assist (ISA)
  • Proximity monitoring
  • Lane departure warning (LDW)
  • Lane change assist (LCA)
  • Rear view cameras

Whether your vehicle only has one of these features or many, ADAS calibration is still necessary as per your vehicle’s user-manual.

Dynamic ADAS Calibration

Also referred to as mobile ADAS calibration, dynamic ADAS calibration uses a hand-held device that is plugged into the vehicle’s systems. The vehicle is then driven a specific distance at a specific speed, and in optimal weather conditions. The vehicle’s manufacturer will specify the distance and speed in order for the system to adapt to regular road conditions.

Static ADAS Calibration

As suggested by the name, static ADAS calibration happens on a stationary vehicle; no driving necessary. But instead of using a hand-held device, everything happens in a specialised workshop using an array of highly sensitive equipment to test each module or feature and to then return each to optimal functionality.

Static and dynamic ADAS calibration are not interchangeable. Your vehicle manufacturer will indicate which method should be used, along with specific parameters to be used during testing and calibration. It is not something you can do yourself but should only ever be performed by trained professionals with the proper equipment. And unfortunately, it does make tasks such as windscreen replacement longer, with calibration taking anywhere from 30 minutes to more than 3 hours to be completed properly. But the benefits in the form of improved safety for you and other road users are more than worth the extra time.
