Method and device for performing a test run on a test stand

A device for controlling a test bench for performing a test run, comprising:

• a test specimen constructed on the test bench and the test specimen is connected to a load machine,
• a drive control unit provided to set a target dyno value on the load machine,
• a first simulation unit with a first simulation model and a second simulation unit with a second simulation model, separate from the first simulation model,
• wherein the first simulation model calculates at least one longitudinal velocity of a tire and provides it to the second simulation unit, the at least one longitudinal velocity of the tire is a speed of a wheel contact point, and
• the second simulation unit calculates a longitudinal force and/or a rolling resistance torque of the tire based on the longitudinal velocity calculated by the first simulation unit, and determines at least one target dyno value for the drive control unit from that information.
