ABSTRACT:
A load-shifting device having a regulating element (11) which can act on a setting member (16) which determines the power of an internal combustion engine, which regulating element is connected to a driver (4) coupled with an accelerator pedal (1). In addition, the regulating element can be moved by means of an electric setting drive (9), having a desired-value detection element (7) associated with the driver (4), and an actual-value detection element (12) cooperating with the driver and acting on the electric setting drive (9). The electric setting drive (9) is adjustable as a function of the detected values by an electronic control device (22). Between the driver (4) and the regulating element (11), a space-monitoring device (15) is provided which, upon a deviation of driver (4) and regulating element (11) from a predetermined spacing established by the control device (22), feeds a signal for the purpose of plausibility testing. The control device (22), in the absence of defined plausibility conditions, uncouples or disconnects the electric setting drive (9), and the driver (4) and control element (11) are mechanically positively guided.
