Abstract
A running resistance control apparatus of a chassis dynamometer comprises a target vehicle speed calculating section where a target vehicle speed is calculated on the basis of a control torque of a dynamometer, a running resistance torque, a mechanical loss torque, a detected vehicle speed, a vehicle weight and a mechanical weight of roller and a dynamometer. An electric inertia torque is compensated according to a difference between the detected vehicle speed and a target vehicle speed to adjust the detected vehicle speed at the target vehicle speed.
