x-road cuve actual driving situations

x-road curve dynamically tests autonomous cars

x-road curve creates previously impossible options for testing semi-autonomous or autonomous vehicles

In addition to the conventional tests carried out on a roller test stand with roll/brake/ABS testing, dynamic function tests for autonomous vehicles as for example the driving behaviour in typical traffic situations are to be performed in the future on the x-road curve.

illustration autonomously driving car

Perfectly calibrated for autonomous driving

The multi-function test stand x-road curve enables the dynamic testing of autonomous vehicles in the final assembly.

autonomous driving dynamic roll brake test

Dynamic roll/brake test stand with steering function

Finally, the scope of the x-road curve is completed through integration of a simulation environment for integrated vehicle test via typical driving situations.

x-road curve at high speeds

Steering function at high speeds

In addition to the conventional tests carried out on a roller test stand, vehicles can be tested on the x-road curve at high speed taking the vehicle steering into account.

x-road cuve actual driving situations

Close to actual driving situations

No other test bed gets so close to actual driving situations.

The revolutionary idea

On conventional roll test stands, vehicles can only drive straight ahead. In order to avoid a sidedrift of the vehicle and to not create the risk of it being ejected from the test stand, the driver has to constantly ensure that the vehicle remains in the centre of the test stand.

Thanks to the revolutionary test stand concept of x-road curve, it is possible to keep the vehicle in the centre of the test stand fully automatically - thus enabling a driverless vehicle testing - and to automatically carry out tests with steering functions.

  • Testing speed with steering angle
    130km/h
  • Max. steering angle at the front axle
    +/-10°
  • Testing speed without steering possibility
    170km/h
