Abstract: In an apparatus operable with an injection pump of a diesel motor whereby the injection pump has an output setting element and a shut-off element, the output setting element is controllable by a digital control device. Also, the shut-off element is pulsatingly controllable by the digital control device such that a predetermined rotational speed of the diesel motor is achieved.

Abstract: In a device for transmitting the position of a control element (1) which is actuatable by the driver of a vehicle between an idling position and a full-gas position via an electric set-value transmitter (2) which is displaceable by the control element and via electric transmission means, particularly a regulator (3), to a setting member (6) which is displaceable in corresponding manner between the idling position and the full-gas position, which member is coupled by coupling means (12, 13) to a actuating member which controls the fuel/air mixture of an internal combustion engine, an emergency-operation capability is to be obtained by a mechanical safety transmission element. For this purpose, the position of the control element is to be transmitted by the mechanical safety transmission element to the actuating member.

Abstract: 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.

Abstract: 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.

Abstract: In a system for controlling a drive unit, particularly a boat drive unit, which comprises an internal combustion engine and a reversible gearing, with an operating member for adjusting the power and the direction of rotation, the operating member (1) feeds electric signals corresponding to the power and the direction of turning to a control device (5) which contains a microcomputer (6). Actuators (11, 12) for the power of the internal combustion engine and the switching of the reversible gearing respectively are connected to the control device (5). The control device (5) is developed in such a manner that switching of the reversible gearing is only possible when the speed of rotation of the internal combustion engine lies below a predetermined value.

Abstract: The invention relates to an electric gas pedal for automotive vehicles having a desired-value transmitter 1 from which a desired-value signal can be fed to an electronic controller unit 3. The controller unit 3 controls by means of electric signals a setting member 4 which controls the motor power via a displacement device. In order to make optimum adjustment of this electric gas pedal possible in a simple and economical manner, the actual setting range possible for the displacement device is determined and stored as effective desired setting range of the controller unit 3 in the latter.

Abstract: A device for electrically controlling the speed of travel of an automotive vehicle, having a desired-value transmitter 2 which can be displaced by a gas pedal and whose output signal can act on a setting member 5 of a throttle valve 7. A pedal contact 14 can be acted on by the gas pedal 1 in such a manner that when the gas pedal 1 is moved out of the idling position, energy can be supplied to a unit which controls the speed of rotation of the engine. In series with the pedal contact 14 there is arranged a safety contact 15 which can be closed by mechanical actuation of the gas pedal 1 out of its idling position.

Abstract: A device for controlling the speed of travel of an automotive vehicle, having a desired-value transmitter 2 which is adjustable by a gas pedal 1 and the output signal of which can act on a setting member 5 of an element which controls the fuel/air mixture. The device has a setting-member transmitter 29, which produces a signal corresponding to the position of the setting member 5, as well as an alarm circuit 6, 7 via which an alarm signal can be fed to an alarm device when, the desired-value transmitter 2 not being actuated, the setting member 5 is in a gas position. The alarm circuit 6, 7 is developed in such a manner that an error in the alarm circuit 6, 7 can also be indicated.

Abstract: The present invention relates to a device for controlling the position of an element of an automobile internal combustion engine which controls the fuel-air mixture, comprising a desired-value transmitter 2 for producing an electric desired-value signal which can be fed to a electronic control unit 14. A setting member 19 for displacing a throttle valve 20 into a position corresponding to the position of the desired-value transmitter 2 can be controlled by the electronic control unit 14. In order to make smooth starting possible, a controller unit 15, by which the control of the setting member 19 is regulated upon the starting, is arranged between the desired-value transmitter 2 and the electronic control unit 14.

Abstract: A system for controlling the vehicle speed of travel as well as for regulating the idling speed of automotive vehicles having an Otto engine, comprising an actuator which adjusts the position of a regulating element for control of the vehicle speed as a function of the position of a desired-value transmitter. A closure element, as well, which determines the through-put passage cross section of a by-pass, the latter connecting a region in front of the regulating element with a region behind the regulating element, the closure element being displaceable by an automatically controlled actuator. The first-mentioned actuator and the automatically controlled actuator constitute a single actuator means common both for controlling the vehicle speed of travel and for regulating the idling speed. The single actuator actuates the closure element for regulating the idling speed, in a first operating range and operates the regulating member for controlling the vehicle speed of travel in a second operating range.
