Patent abstract

The invention is based on a drive train (10) of a motor vehicle in which a control device (16) limits an output torque of a drive machine (14) to a first maximum value or a second, higher maximum value. The object of the invention is to propose a drive train which permits low fuel consumption. According to the invention, the control device (16) has a signal transmitting connection to a roadway information device (camera 53) which supplies information relating to a profile of the roadway in front of the motor vehicle. The control device (16) can thus predictively change from the first maximum value to the second maximum value or carry out shifting back in the transmission (19).
