Abstract
A drive train of a motor vehicle, with a drive engine, a torque converter, an additional brake, a retarder, a manual actuator device for a power control element, a manually operated preselector element for an operating range of the torque converter, a manually operated preselector element for selecting braking resistance of the additional brake, a manual control element for actuating a brake that decelerates the motor vehicle and an electronic control unit for exchanging and processing signals and data of the drive train and/or of the motor vehicle. The preselector element for the additional brake is connected to the electronic control unit such that starting from a zero position '0', it can be actuated in a direction 'I' for signaling the selection of a braking resistance of the additional brake, and also in another direction “II” for signaling the activation of a drive-power-off rolling or coasting operation mode.
