摘要:
A device for the electric control of the speed of an automotive vehicle having a guide signal transmitter developed as settable memory, having a comparison element fed with the guide signal and a vehicle-speed signal, having a control amplifier which is arranged behind the comparison element and gives off a set signal to a setting drive for the displacement of a throttle valve which controls the air-fuel mixture of an internal combustion engine, having a position indicator coupled with the throttle valve apparatus and having a guide signal transmitter developed as settable memory. A comparator for comparing the set signal with a feedback signal given off by the position indicator is provided, the output value of which sets the guide signal transmitter at such a large guide signal that the position of the throttle valve at an end of the setting process, which has been determined during the setting by a driver, is established by the set signal.
摘要:
A setting device for the controlled displacement of a stop connected with a setting member, particularly an idling stop of an internal combustion engine.The idling stop of the internal combustion engine should not be actuated by such a setting device when the internal combustion engine is intentionally operated at a speed of rotation above the idling speed. If it were, then the idling stop would be so displaced by a control electronic system during the intentional giving of gas that the internal combustion engine would run too slowly or die out upon the following idling. In order to avoid such displacement of the idling stop when the internal combustion engine is operating at travel speed without expensive interruption of the signal flow paths from and/or to the control electronic system, a clutch (3) is arranged between the stop pin and an electric motor as drive member. The clutch is connected with the stop pin (8) by a self-locking gearing (15). The clutch is capable of transmitting force only when the stop pin is to be displaced by the idle or control electronic system since in this case the spring connected with the throttle valve strikes, via the stop (14), against the stop pin (8) and presses the two clutch parts (4, 5) together.
摘要:
A device for the control of the traveling speed of a motor vehicle with a control member actuatable by the vehicle driver, particularly a gas pedal, which is coupled with a first position encoder or indicator, with an electric controller for the transmission of the adjustment movement of the control member to an element, which element influences the fuel-air mixture, particularly to a dosing member of a fuel injection pump, by means of an electric motor, the electric motor being in operative connection with the dosing member and acting against the force of a return spring, which electric motor is supplied with a motor current which current is formed in the controller, as well as with a second position encoder which second position encoder is coupled with the dosing member, the second position encoder being arranged in a feedback circuit with inclusion of the controller. The construction and sizing of the feedback circuit is such that the motor current variation which is formed by the feedback circuit is limited to or by an amount sufficient for the correction of the greatest possible position error of the regulating unit.
摘要:
A device for the control of the traveling speed of a motor vehicle with a regulating unit which is actuatable by the vehicle driver, particularly with a gas pedal, with electrical means for the transmission of the movement of the same to an element which influences the fuel-air mixture, particularly a throttle valve, with an electrical controller, the element which influences the fuel-air mixture being in operative connection with the output of the electrical controller, and with at least one comparator, one of the inputs of the comparator being applied with a voltage which is proportional to the rotational speed of the motor and its other input being applied with an adjustable constant voltage value for the rotational speed limitation. As a controller a PI controller is connected in parallel with a P-controller of great amplification.
摘要:
An electrical regulating device, particularly for a speed control device for motor vehicles, with a servomotor, a rotatably mounted setting element which actuates the position or adjustment actuator, the setting element being in operative connection with the servomotor via an electro-magnetic coupling, and a monitoring stage for the mechanical functioning of the coupling. The monitoring stage contains a unit for recognizing the restoring speed of the setting element or the adjustment actuator, a unit for comparison of the actual resetting speed with a pregiven reference value and a unit for production of a signal upon an unsafe deviation of the actual resetting speed from the reference value.
摘要:
Device for controlling of the traveling speed of a motor vehicle with an electrical controller, which controller, by an electrical adjusting device in dependency on a desired value which is fed-in or stored by the driver via one or more manually actuatable first actuating elements, acts on an element which influences the ratio of the fuel-air mixture fed to the motor vehicle, particularly the throttle valve, and its adjusting device is switchable inoperatively off by second actuating elements. Elements are provided by which the controller can be turned off if at least one first actuating element and at least one second actuating element are in their active position or condition.
摘要:
A speed regulating device for motor vehicles, wherein a setting element is arranged to affect the fuel/air mixture supplied to the engine of the vehicle in response to a control signal, and including an electrical regulator and a variable resistor associated with the setting element and the electrical regulator for signalling to the electrical regulator the actual position of the setting element, the feedback means including a lost motion connection whereby a predetermined movement of the setting element is required before an indication of change or reversal of movement of the setting element is communicated to the electrical regulator, thereby eliminating hunting of the speed regulating device caused by looseness or play in mechanical linkage between the setting drive and throttle valve.
