ABSTRACT:
A load adjustment device has a control element (8) for action on at least two setting members (9a, 9b) which determine the output power of an internal combustion engine. The control element is spring-coupled with a driver (3) which can be actuated via an accelerator pedal (1) and, in addition, can be moved by means of an electric setting drive (10). A desired-value detection element (5) is associated with the driver and an actual-value detection element (22) which acts on the electric setting drive and cooperates with the desired-value detection element is provided. The electric setting drive is adapted to be controlled as a function of the values detected by an electronic control device (6). The setting members are developed, in particular, as throttle valves, the driver being adapted to be brought into functional relationship with all setting members, and the electric setting drive being adapted to be brought into functional relationship with at least one of the setting members.
