    • 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.

    • 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).

    • 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.

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.
