Patent ID: 8016724

Claim:
A drive train of a motor vehicle comprising: a drive engine, a torque converter, an additional brake, a manually operated actuator device for a power control element of the drive engine, a manually operated first pre-selector element for an operating range of the torque converter, a manually operated second pre-selector element ( 1 ) for selecting a defined braking resistance of the additional brake, a manually operated control element for actuating an other brake that decelerates a driving speed of the motor vehicle, and an electronic control unit for receiving, processing and emitting signals and data of at least one of the drive train and the motor vehicle, wherein the second pre-selector element ( 1 ) of the additional brake is connected by control technology means to the electronic control unit such that the second pre-selector element ( 1 ) is manually actuatable, from a zero position (“0”), in a first direction (“I”) for selecting the defined braking resistance of the additional brake, and in a second direction (“II”) for actuating one of a drive-power-off rolling and coasting operation mode of the motor vehicle such that a drive torque delivered by the drive engine is disconnected.
