ABSTRACT:
An arrangement controls the torque to be supplied by a drive unit of a motor vehicle especially a motor vehicle at standstill or a rolling motor vehicle. Apparatus are provided which compute the adjustment of the power parameters of the drive unit which is necessary for making this torque available. A correction is provided at least in dependence upon the torque requirement of a transmission unit of the motor vehicle in idle or near-idle range outside of driving operation. In addition, corrective devices with respect to engine torque loss as well as torque requirements of ancillary equipment of the motor vehicle are provided. These characteristic fields are adaptatively determined in a further embodiment and can be adapted to deterioration.
