Abstract
A combined engine and transmission control unit for a motor vehicle uses the position of the accelerator pedal to calculate setpoint values for the engine and the transmission of the motor vehicle. The control unit has a drive-train controller, which, when the engine is not in traction mode, controls the driving mode of the motor vehicle. The driving mode is adapted to the surroundings of the motor vehicle and the driving style of the driver. The drive-train controller activates an engine torque control when brake slip is detected, and the transmission controller prescribes a lower gear than is provided for the unbraked mode of the motor vehicle by a characteristic diagram.
