Claim One:
1. A control device for a chassis dynamometer system including a torque sensing means and a rotational speed sensing means which outputs a control signal for controlling a dynamometer on the basis of a control equation having parameters including a sensed torque and a sensed rotational speed of said dynamometer and an inertia of a vehicle to be tested and a mechanical inertia of said dynamometer system and including control coefficients, said control signal controlling said dynamometer so as to control a mechanical force to be absorbed therein when said dynamometer is connected to a rotating roller on which a driving wheel of said vehicle to be tested is place via a shaft which is provided with a flywheel, said control device comprising a means for automatically adjusting said control coefficients of said control equation utilized in said control device in accordance with changes in said mechanical inertia of said dynamometer system.
