Abstract:
1. A steering test stand for testing a steering control unit comprising: a first steering device comprising: a measurement device configured to measure a first value of a steering torque on the first steering device and an actual steering angle on the first steering device; a first drive motor coupled to the steering gear for applying a force or a torque to the steering gear; and a second drive motor coupled to the first steering device, configured for setting a first steering angle on the first steering device according to a target steering angle; a control unit coupled to the first drive motor and the second drive motor; a first computer unit coupled to the control unit including a program for simulating static and/or dynamic properties of a motor vehicle, wherein the first computer unit is configured to receive the actual steering angle measured by the measurement device and to transmit simulated target values for the first drive motor and/or the second drive motor to the control unit; and wherein a test driver unit includes a second steering device in the form of a force feedback steering wheel; and wherein a first coupling is provided between the test driver unit and the control unit, and is configured to transmit a second steering angle, which is set on the force feedback steering wheel as the target steering angle and/or a steering angular velocity occurring on the force feedback steering wheel to the control unit; and wherein a second coupling is provided between the test driver unit and the measurement device, which is configured to transmit the first value of the steering torque measured on the first steering device to the test driver unit; and wherein the second steering device in the test driver unit is configured to set a second value of the steering torque as a function of the first value of the steering torque.
