ABSTRACT:
For simulating a road test of an automotive vehicle having an engine driving a traction wheel through a semi-automatic change-speed transmission, there is provided an anchor for holding the automobile stationary and with the traction wheel in engagement with a roller coupled to a hydraulic pump-motor. There is a hydraulic loop interconnecting the pump-motor and a reservoir and in the loop there is a flow control valve variable to control flow resistance. There is also an accumulator joined to the loop and various valves for controlling and changing the operation of the hydraulic circuitry. Data are taken at various points and displayed and graphed at an accompanying console.
