<p>A transmission/engine control (1) for a motor vehicle with an automatic transmission (2) having a warning apparatus (3) for a disturbance of a signal transmission from an electrical position recognition apparatus (4) of a selection lever (5) which acts on the regulating device of the automatic transmission, via an electronic transmission control. The warning apparatus (3) has the purpose of notifying the driver that no further change in the direction of travel can be executed and the warning apparatus (3) coacts with a program module of a transmission independent processing unit (6) which, upon occurrence of the disturbance of the signal transmission, initiates an emergency operating mode of the automatic transmission (2) and determines a vehicle speed which is less than a specified threshold value. The processing unit (6) communicates a maximum allowable motor torque and/or a maximal allowable motor speed of rotation to a program module of a motor control (7). Alternatively, the warning apparatus (3) can provide a signal to a control apparatus (10) of a vehicle brake system for the activation of the brake system or signal to a locking apparatus (12) to lock the selection lever in its existing position, or the warning apparatus can provide the driver with an optical or an acoustic advisory indication.</p> |
