Abstract: A displacement device (1) for the actuation of a displacement member (4) of a control of an internal combustion engine is disclosed having an accelerator pedal (2) and a linkage (3) which forms a mechanical connection between pedal and adjustment member, the pedal (2) and the linkage (3) together forming a force-transmission path. In such a displacement device, the plausibility verification for the relationship between the position of the pedal (2) and the position of the adjustment member (4) is to be improved. For this purpose, a force sensor (8) is arranged within the force transmission path. A memory (15) stores relationships of force to displacement of the linkage. A signal processor 10 uses data of the memory to direct a motor (13) to correct a position of a throttle valve (12) to provide a desired amount of fuel to an engine in event of a failure of the linkage.

Abstract: The method for monitoring the end positions of a controlling element having a servomotor (1) comprises the recognition of the end position, for instance by interruption of the flow of current to the servomotor by limit switches (4, 5), and the subsequent action of a control pulse of opposite direction on the servomotor in order to brake the servomotor.

Abstract: In the method for adjusting a controlling element, a marking point which can be recognized by the controller unit which controls the controlling element and is at a given distance from the adjustment point is selected in the vicinity of the desired adjustment point, said distance corresponding to a given number of control pulses which are necessary in order to adjust the controlling element with close tolerances to the desired adjustment point. When a switch is used as the marking point, the distance should be so great that after movement beyond this marking point the switch passes into a precisely defined switch condition.

Abstract: A pump for a coolant circuit of an internal combustion engine of a motor vehicle includes a temperature sensor integrated into the pump for detecting the temperature of the fluid flowing into a pump chamber. The temperature sensor is inserted into a recess of a pump casing of the pump. The recess produces a reduced wall thickness (d) in the region proximate the temperature sensor. The reduced wall thickness improves the heat transition through the pump casing from the fluid to the temperature sensor and reduces the outlay in terms of production. Furthermore, the temperature sensor is arranged on a carrier material common to a control of the pump so that the susceptibility of the contacting of the temperature sensor to faults is reduced.

Abstract: 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.
