摘要： A control system for an internal combustion engine comprises an electronic controller unit (3) which evaluates signals of a speed transmitter (8) and, upon reaching a predetermined maximum speed, displaces, via a controlling element (4), a displacement device (7) which is provided for the regulating of the engine output. In order to make the intermediate giving of gas possible even upon reaching the maximum speed and thus upon the downward regulation of the engine output, there is provided a neutral position recognition switch (10) which in the neutral position of the transmission (9) feeds a signal to the controller unit (3), which signal is so processed in a recognition circuit of said controller unit that the speed limitation is placed out of operation. At the same time, a position limitation of the controlling element is established in order to permit a load-free speeding up of the internal combustion engine in order to reach the shift speed of rotation, and at the same time, however, prevent exceeding of the speed limitation.

摘要： A system for the actuation of a setting element with a digital actuation device, particularly for a motor vehicle, wherein the digital actuation device is connected with a monitoring circuit which, upon failure of the digital actuation device, switches a by-pass of the digital actuation device. Preferably the digital actuation device comprises a microcomputer, from an output of which uniform signals are supplied during the course of the program, which signals are evaluated by the monitoring circuit.

摘要： An apparatus for actuation of a setting element has a desired value transmitter and an actual value transmitter for the deflection of the setting element from a rest position. The apparatus includes an electronic controller, particularly for a motor vehicle, wherein the deflection of the setting element is proportional to an electric current fed to the element by the controller. An operating mode of the controller is provided by which a signal emanating from the desired value transmitter is converted into a current proportional to a desired value.

摘要： The safety monitoring of an electrical gas-pedal system having a desired-value transmitter (2), a controller unit (3), a controlling element (4) and safety contacts (8 and 9 respectively) associated with the desired-value transmitter and the controlling element includes the possibility of checking the safety contact (9) of the controlling element even if, as a result of an increased idling-speed-of-rotation control position or a mechanical limitation, the control position of the controlling element lies above the switch point of the safety contact. For this purpose, when the engine speed of rotation exceeds a given threshold value (ns) which results from the increased idling speed of rotation plus a safety margin, in the absence of a corresponding signal from the desired-value transmitter push operation is recognized by the controller unit (3), and the controlling element (3) is moved back to such an extent that the safety contact (9) must have switched. If a switching of the safety contact (9) does not take place then an error response is brought about.
