摘要： A monitoring device for an electronic accelerator pedal (1) in a motor vehicle has an accelerator pedal position sensor (2) mechanically connected to the accelerator pedal (1), a butterfly valve (7), a servo-motor (5) for the butterfly valve (7) and a butterfly valve position sensor (6) mechanically connected thereto. A regulator (3) receives a desired value (.alpha.D) from the accelerator pedal position sensor (2) and an actual value (.alpha.A) from the butterfly valve position sensor (6) and controls an output stage (4) for the servo-motor (5) in response to the comparison. A subtractor (14) in a slave circuit (12) forms the difference (.alpha.E) between the desired (.alpha.D) and actual (.alpha.A) values of the butterfly valve opening angle. An integrator (16) integrates the control difference (.alpha.E) and is re-set to zero when the control difference (.alpha.E) is zero or changes sign, whereupon integration of the control difference (.alpha.E) is resumed. A limit device (18) indicates to a master circuit ( 10)the presence of a fault condition when the integrator output exceeds a predetermined limiting value.

摘要： A headlamp for a power vehicle comprises a reflector having an apex, a light source arranged in the apex of the reflector, and a dimming device which is formed so that in a position for high beam it allows light from the light source to reach a lower reflector region or allows the light to exit the same, and in a position for low beam it keeps away light from said light source from the lower reflector region or blocks light reflected from the lower reflector region. The light source is formed as a gas discharge lamp with an axial light arc, an upper reflector region is formed for producing a light distribution for low beam while the lower reflector region is formed for producing a light distribution for high beam.

摘要： A method is proposed for monitoring a computer network having at least two subscribers connected via a databus comprising at least two lines, said subscribers having in each case one receiving component and/or one transmitting component. The method is characterized by the fact that the functioning of the databus and/or the functioning of the subscriber is monitored with the aid of error detection signals (watch-dog signals, CEI) of at least one subscriber, and emergency operation measures (M1; M2), matched to the respective error case, for setting defined emergency modes of operation (single-wire mode, special emergency mode) are taken. After taking the first emergency operation measure (M1), it is tested whether the computer network is functioning free of errors. If this is the case, the first emergency operation measure is maintained and thus also the emergency mode of operation (single-wire emergency mode) adopted. If further errors should arise in the computer network after the first emergency operation measure has been taken, the first emergency operation measure is cancelled and the second emergency operation measure (M2) is taken. If, from now on, no further errors arise, the emergency operation mode, the special emergency mode, set by this measure is maintained. Only if further errors continue to arise are the affected subscribers or the entire computer network switched off (bus-off).

摘要： A system for transferring a control position of a set-point value transducer between the gas pedal and the throttle valve. The system includes an electromechanical device which can adjust a throttle valve out of its position of reponse in opposite directions. This is attained by an intermediate element, which is capable of coming to rest on a repose-position stop. The system is particularly well suited to motor vehicles having traction and/or cruise control.

摘要： A method is proposed for influencing the electrical power of a load with the assistance of a pulse-width modulated signal, the latter including the requirement of a continuous turn-on signal. The method provides that the continuous turn-on signal is terminated by an interrupt signal and that the continuous turn-on signal is followed by a clock-pulse phase having at least one fundamental period duration of the pulse-width modulated signal, the period including a turn-off time. The occasional interruption of the pulse-width modulated signal, which is present as the continuous turn-on signal, makes it possible to detect an operational quantity of the load that only arises during a power change in the load.

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 clocked power supply is proposed which contains a fault current detection means (32) which evaluates a voltage drop occurring at an ohmic measuring resistor (25), and emits a switch-off signal (40) to a clocked voltage converter (5). The ohmic measuring resistor (25) is arranged in a line (24) of the clocked voltage converter (5) in which the alternating operating current of the clocked voltage converter (5) flows, the frequency of which alternating operating current is equal to the frequency of a switching signal (23) with which a circuit breaker (16) is operated. In order to suppress the portion of the voltage drop which can be tapped at the ohmic measuring resistor (25) and whose frequency corresponds to that of the switching signal (23), means, for example a low pass filter (33) and/or a parallel capacitor (26) which bridges the ohmic measuring resistor (25) are provided. The clocked power supply according to the invention is particularly suitable for operating gas discharge lamps (7) which are installed for example in motor vehicles, an effective protection of persons (30) against inadvertent contact with live components being provided.
