ABSTRACT:
A method for establishing malfunctions of components of a motor vehicle power train as well as the reaction to the same. The power train has a drive motor and an automatic transmission with respectively allocated control devices, setting apparatus and sensors, and the transmission input shaft is allocated a torque sensor for recording the transmission input shaft. During operation of the motor vehicle, the functions of the control devices, the operating elements, the sensors and their data transmission apparatus as well as the measured values of the transmission input torque are recorded and checked for signs of malfunction. After recognizing such a malfunction, operations are conducted by means of which the motor vehicle can be further operated in an emergency type of operation or with the aid of which the driving operation can be safely ended.
