Patent ID: 8123659

Claim:
In a motor vehicle, a method for preventing an uncontrolled rollback of a motor vehicle, said motor vehicle comprising: a motor; a transmission that is selected as one of an automated shift transmission and a dual clutch transmission; at least one controllable clutch transmitting a clutch torque from the motor into the transmission; and a control controlling the clutch torque, said method comprising the method steps: controlling the engagement of the at least one controllable clutch for controlling the clutch torque; controlling the clutch torque such that in case a rollback is detected, said rollback being a movement in opposite direction as a predetermined direction of movement of the motor vehicle having disengaged brakes, a clutch torque is transmitted via the clutch, said clutch torque acting against the rollback direction; increasing the clutch torque with increasing rollback speed when a first rollback speed is exceeded up to a maximum clutch torque at a second rollback speed that is higher than the first rollback speed; limiting the clutch torque to the maximum clutch torque for any rollback speeds exceeding the second rollback speed; and regulating down the clutch torque such that a predetermined creeping speed in the predetermined direction of movement is not exceeded as long as no starting mode has been chosen.
