Abstract
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.
