ABSTRACT:
A method and a device for dynamometer testing of a motor vehicle, having a front end and a rear end and a right side and a left side, as seen in a driving direction, and/or vehicle components, by measuring torque and rotational speed on drive shafts of the vehicle. A braking torque is applied to each one of the shafts by individual hydraulic dynamometer test units by throttling hydraulic fluid flows. The braking torque is adjustable for each individual one of the drive shafts such that a resulting individual rotational speed for that shaft corresponds to a virtual vehicle speed when driving the motor vehicle on a road, compensated with a slip value.
