1. A test system for testing vehicle systems comprising at least one sensor, the test system comprising:
- a test stand for accommodating a vehicle,a sensor support for accommodating the at least one sensor,an object which is movable relative to the at least one sensor,a track, the object being movable relative to the at least one sensor along the trackat least one deceleration member at an end of the track capable of absorbing kinetic energy of the object,a speed measurement unit for detecting a virtual speed of the vehicle; and
a control unit for controlling a relative movement of the object towards the at least one sensor along the track in dependence on said virtual speed detected by the speed measurement unit.

Abstract
A test system (1) is arranged for testing vehicle systems which comprise at least one sensor (20). The test system comprises a test stand (11) for accommodating a vehicle (2), an object (12) which is movable relative to the test stand, and a control unit (13) for controlling the movement of the object. The test stand (11) is provided with a speed measurement unit (14) for detecting the virtual speed (v) of the vehicle, while the control unit (13) is arranged for controlling the movement of the object in dependence on said virtual speed. The object (12) preferably is a dummy vehicle which may be pulled along a track (16).

13. A method of testing vehicle systems comprising at least one sensor, the method comprising the steps of:
-
accommodating a vehicle on a test stand, detecting a virtual speed of the vehicle, controlling a movement of an object, on a track, relative to the at least one sensor, wherein at least one deceleration member is positioned at an end of the track, the deceleration member being positioned to absorb kinetic energy from the object, and the relative movement of the object along the track being controlled in dependence on said virtual speed until the object is brought to a halt by the at least one deceleration member. - View Dependent Claims (14, 15)
