ABSTRACT:
A load adjustment device has a control element (9) which acts on a setting member (10). The setting member 10 determines the output of an internal combustion engine and is spring-coupled with a driver (3) which can be actuated via an accelerator pedal (1) and is furthermore moveable by means of an electric setting drive (11). A desired-value detection element (6) is associated with the driver. An actual value detection element (19) cooperates with the desired value detection element and is associated with the control element and acts on the electric setting drive. The electric setting drive is adapted to be controlled as a function of the detected values by an electronic control device (7). The control element has a first control-element part (9a) associated with the setting member and a second control-element part (9b) associated with the setting drive. An idle-path coupling element (17) permits relative mobility, limited by stop at least in one direction of control, of the control-element parts, at least over a partial adjustment range of the control element. The development of the load adjustment device permits control of the setting member from the accelerator-pedal side, independently of the setting-drive-side when the setting drive is not activated. When the setting drive is activated, a control process can be effected in at least one direction of control.
