Abstract
The invention is directed to an arrangement for controlling the output power of the drive unit of a motor vehicle. The drive unit includes a drive motor for generating an output torque, a transmission unit and a power transmitting device including a torque converter interconnecting the drive motor and transmission unit for transmitting torque therebetween with the power transmitting device having an output torque, the transmission unit having a transmission ratio and the torque converter having an amplification. The arrangement includes a circuit for supplying a signal indicative of a driver command and a control apparatus. The control apparatus determines a desired value for the output torque of the drive motor occurring at the output end of the power transmitting device and determines a desired value for a drive motor torque from the desired value of the output torque and from variables representing the transmission ratio of the transmission unit and the amplification of the torque converter. A desired value is provided for the drive motor torque to adjust the desired value of the output torque. The apparatus controls the drive motor torque in accordance with the desired value.
