Abstract:
1. A drive train of a motor vehicle, comprising: a drive machine; a transmission; and a control device for actuating the drive machine, the control device adapted for limiting an output torque (M wherein the control device has a signal transmitting connection to a roadway information device which supplies information relating to a profile of the roadway in the direction of travel of the motor vehicle, and the control device is adapted for carrying out a changeover from the first maximum value (M and wherein the transmission is embodied as an automatic transmission and is actuated by the control device, such that when a request for an increased torque (M the requested increased torque test, which tests whether the requested torque (M a roadway profile test, which tests whether owing to the information relating to the profile of the roadway it is to be expected that a necessary torque of the drive machine will remain lower than the second maximum value (M in the case of the result of both tests being positive:
