Abstract

A steering test stand has a first steering device with a measurement unit measuring the steering device torque value and applies forces to the steering device and control unit and has a control unit connected to a computer for controlling actuators. The computer simulates static and/or dynamic properties of a motor vehicle and transmits simulated target values to the control unit. A test driver unit comprises a second steering device as a force feedback steering wheel and a connection between the test driver unit and the computer, transmits a second steering angle set on the force feedback steering wheel. A second connection between the test driver unit and computer transmits steering torque measured on the first steering device to the test unit, such that the second steering device sets a second steering torque value on the force feedback steering wheel as a function of the first value.
