    摘要: A circuit arrangement for converting a DC voltage into another DC voltage, with simultaneous regulation of the emittable voltage (U.sub.A) at a predetermined value. The circuit arrangement includes a combination of an upward and a downward transformer having at least one switching transistor (3) connected in series with a common memory coil (1) to a circuit output terminal, and a smoothing capacitor (5) connected in parallel to the output load (6), i.e., across the output terminals. The coil (1) is connected for a specific time to the supply voltage source (U.sub.Bat) by a time function circuit (9, 10). The coil (1) is connected directly to the positive pole (+) of the supply-voltage source (U.sub.Bat), and a current limiter circuit is provided in the long or forward branch of the circuit arrangement in front of the output of the circuit arrangement, with the current limiter circuit comprising a resistor (4) and a transistor (15) and influencing the switching transistor (3) disposed in the long branch. In addition to a first voltage limiting circuit formed of a series connection of a resistor and a Zener diode (16, 17), a further voltage limiter circuit (18, 19) is provided in parallel with the first voltage limiting circuit as short-circuit protection, with the further limiter likewise comprising the series connection of a resistor (18) and a Zener diode (19) which, however, has a different breakdown voltage than the first Zener diode (17).

    摘要: A vehicle security arrangement includes at least one functional control unit, which provides a first code word; a theft protection control unit, which is coupled via a bus to the at least one functional control unit; and at least one input unit, which transmits to the theft protection control unit a second code word which the theft protection control unit forwards to the at least one function control unit. The theft protection control unit may initiate the provision of the first code word and the second code word. In the at least one functional control unit, a comparison of the first code word of the at least one functional control unit with the second code word takes place. In case of agreement between the first code word and the second code word, the at least one functional control unit enables itself.

    摘要: A control system is provided for an internal combustion engine in a motor vehicle in which a potentiometer (11) responsive to the position of an accelerator pedal (12) provides a desired position signal to a comparator (15) controlling actuating signals to a servo motor (17) actuating a butterfly valve (18) and a second potentiometer (20) responsive to the position of the butterfly valve (18) provides a feedback signal to the comparator (15). The control system includes a safety device (24) controlling the fuel supply and/or ignition system, a third potentiometer (25) responsive to the position of the accelerator pedal (12), a fourth potentiometer (29) responsive to the position of the butterfly valve (18), and two threshold value switches (TS1,TS2) responsive respectively to the signals from the third and fourth potentiometers (25, 29) and providing output signals when such signals are respectively at or above a first predetermined voltage (V.sub.1), and below a second predetermined voltage (V.sub.2). The safety device (24) becomes operative in the absence of output signals from both the threshold value switches (TS1, TS2).

    摘要: The invention is directed to a system for electronically open-loop controlling or closed-loop controlling the power of an internal combustion engine of a motor vehicle with an electrically actuable actuator influencing the engine power. The adjustment of this actuator is undertaken in dependence on a predetermined and an actual value for producing a match between pregiven and actual values. With the disappearance of a previously detected electrical disturbance of the system, the function is again taken up in a delayed manner.
