During these tests, the following manoeuvres are performed:
- Drive forward at a sufficiently high speed and then brake 'hard'. An acceleration of 8m/s² should be measured, and this for a longer period of time.
- Drive backwards and then brake. Here, the acceleration must be 5m/s².
- Take a roundabout at sufficiently high speed. A transverse acceleration of 5m/s² should then be noted.
- Make an S-shape and brake at the end. Measure 5m/s² of transverse acceleration in both directions. During braking also 5m/s² acceleration.
To ensure the safety of the driver and the truck, support wheels are added. These support wheels prevent the truck from tipping over. This is because an acceleration of 0.5g or 5m/s² brings the truck close to its tipping point.
In addition, accelerometers are also mounted on the truck. In this way, one can monitor whether the intended acceleration is achieved.
