ABSTRACT:
A displacement device (1) for the actuation of a displacement member (4) of a control of an internal combustion engine is disclosed having an accelerator pedal (2) and a linkage (3) which forms a mechanical connection between pedal and adjustment member, the pedal (2) and the linkage (3) together forming a force-transmission path. In such a displacement device, the plausibility verification for the relationship between the position of the pedal (2) and the position of the adjustment member (4) is to be improved. For this purpose, a force sensor (8) is arranged within the force transmission path. A memory (15) stores relationships of force to displacement of the linkage. A signal processor 10 uses data of the memory to direct a motor (13) to correct a position of a throttle valve (12) to provide a desired amount of fuel to an engine in event of a failure of the linkage.
