Abstract: The invention relates to a test bed and a method for testing a real test object in driving operation, wherein the test object has at least one real component of a vehicle which is capable of applying torque to a wheel hub. The test bed comprises a load machine configured to be connected to the wheel hub so as to transmit torque, an actuator configured to generate a relative movement between the wheel hub on the one hand and a vehicle frame supporting the wheel hub on the other, simulation means for simulating the driving operation, wherein the simulation means is configured to simulate a virtual wheel and dynamics of the virtual wheel as if it were arranged on the wheel hub, and control means configured to operate the real test object in consideration of the simulated dynamics of the virtual wheel on the test bed.
