Abstract
A system for a motor vehicle has a motor vehicle gearbox by means of which a reversal of the direction of travel can be initiated, a vehicle brake unit which is separate from the motor vehicle gearbox, and a control unit. When there is a reversal of the direction of travel from at least one first direction into a second direction when there is still a positive vehicle velocity in the first direction, the control unit generates a braking torque which reduces the vehicle velocity, by means of an actuation unit and by means of the vehicle brake unit. The actual direction of travel of the motor vehicle is determined here by means of a sensor unit.

System for a motor vehicle having a motor vehicle gearbox by means of which a reversal of the direction of travel can be initiated, having a vehicle brake unit which is separate from the motor vehicle gearbox, and having a control unit, wherein, when there is a reversal of the direction of travel from at least a first direction into a second direction when there is still a positive vehicle velocity (v) in the first direction, the control unit generating a braking torque (M) which reduces the vehicle velocity (v) by means of an actuator unit and by means of the vehicle brake unit, the direction of travel being sensed by means of a sensor unit.
Method for controlling a system having a motor vehicle gearbox by means of which a reversal of the direction of travel can be initiated, and having a vehicle brake unit which is separate from the motor vehicle gearbox, when there is a reversal of the direction of travel from at least a first direction to a second direction when there is still a positive vehicle velocity (v) in the first direction, a braking torque (M) being generated by means of an actuator unit and by means of the vehicle brake unit, the execution of the method being dependent on a sensed direction of travel of the motor vehicle.
