Chassis Dynamometer Programming-A New Level of Realism Achieved 741004

This paper describes a new, closed-loop programming system which faithfully transfers road operation to the chassis dynamometer. The system provides stable, rapid, accurate response to programmed speed and throttle position changes. Using a derivative of a torque-related signal, changes in power train performance are compensated realistically by electronic modification of either throttle or speed signals as a function of part or wide open throttle command. Under conditions of minor power loss, part throttle compensation is found to restore such uncontrolled parameters as engine speed and driveline torque to the values measured without engine degradation.
