| 摘要 |
The invention relates to a drive train (12) for a motor vehicle (10), comprising at least one friction coupling (22, 24) and a stepped transmission (26, 28), that is connected to an output member of the friction clutch (22, 24). Said friction clutch (22, 24) is open in the base state and can be offset by means of an associated actuator (38, 40) in a slip or closed state. An electronic control unit (32) is connected to an associated power level (34, 36) that changes the control signals of the control unit (32) into power signals in order to operate the actuator (38, 40). An electronic safety circuit (50) is separate from the control unit (32), that is designed in order to allow the actuator (38, 40) to be supplied with power signals in the event of the control unit (32) being reset. |
