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.

Abstract: The invention relates to a method for operating a driving simulator having the following steps: detecting a braking request in the driving simulator, in particular on the basis of actuation of a brake actuator; converting the detected braking request into at least one braking signal suitable for characterising the braking request; transmitting the at least one braking signal from the driving stimulator to a test bench on which are mounted at least part of a drivetrain with at least one axle section of a vehicle, in particular an axle half, and at least one brake associated with the at least one axle section; rotating the at least one axle section at a wheel speed which corresponds to a predefined speed of the vehicle; actuating the at least one brake of the vehicle on the basis of the at least one braking signal; setting a predefined torque or a predefined wheel speed of at least one axle section of the at least one dynamometer on the basis of properties of at least one component of the vehicle, in particular of the drivetrain, of the vehicle and/or of the entire vehicle, wherein the properties are at least partially simulated; detecting the actual wheel speed at a predefined torque or the actual torque at a predefined wheel speed; and outputting the actual wheel speed or the actual torque to the driving simulator.
