In electronic systems for power adjustment in motor vehicles, conventional mechanical linkages or Bowden cables are replaced or supplemented by the transmission of electric signals. Such an electronic power adjustment device contains a control unit (6) which acts on the power adjustor (9) via an electric actuator (8). In order to influence the engine power, an accelerator pedal (5) is provided as a setpoint generator. In a converter (7), the accelerator pedal position is converted into an electric signal which is supplied to the control unit (6). During the starting of the vehicle, a driving authorization control is carried out. The vehicle engine can already be started during the driving authorization control, but accelerator pedal position is taken into account by the control unit (6) only when the driving authorization control is concluded positively. This ensures both a reliable control of driving authorization and comfortable and reliable starting of the vehicle engine by an authorized driver.
A method for controlling a power adjustment means of a vehicle engine, in which the vehicle engine is started by the actuation of an ignition starter lock system, the position of an accelerator pedal is converted into an electric signal and the signal proportional to the position of the accelerator pedal is supplied to a control unit which, from the electric signal of the accelerator pedal position and from further measurement signals, generates an output signal for controlling the power adjustment means, wherein
A device for controlling the power of a vehicle engine (4), said device containing an accelerator pedal (5), a converter (7) for converting the accelerator pedal position into an electric signal and a control unit (6) for converting the electric signal of the accelerator pedal position and further measurement signals into an output signal for controlling a power adjustment device (9) of the vehicle engine (4), wherein there are, furthermore, means (1, 2, 3) for carrying out driving authorization control, which are connected to the control unit (6) in such a way that, during the driving authorization control, the output signal from the control unit (6) is formed solely from the further measurement signals, without the signal of the accelerator pedal position being taken into account wherein the vehicle engine is able to be started prior to carrying out driving authorization control.
