摘要： A short-circuit-resistant trigger circuit layout is proposed for an electrical consumer for motor vehicles. The trigger circuit layout is located in series with a switching transistor, which is preceded in turn by an operational amplifier whose negative input is coupled with the junction point of two resistors parallel to the transistor and whose positive input receives both an average constant potential and a dynamic switching signal. In case of error, that is, in case of a short-circuit consumer, the transistor, which has initially been switched on, switches back into its blocked state after a predetermined time constant has elapsed. The short-circuit current flowing during this open phase can be limited by means of a resistor in series with the transistor.

摘要： The Schmitt trigger threshold switch which produces rectangular waves in response to the output of a rotary ignition timing generator has a variable bias applied to its switch-in threshold which is proportional to the amplitude of the generator output, while the switch-out threshold remains fixed at or near zero voltage. The bias, which may be developed by a peak detector, prevents inherent ignition timing shift as the generator turns faster. The Schmitt trigger utilizes an inverting comparator so that a "lowest-wins" circuit can be used for applying stabilizing negative feedback or bias to the comparator. The bias provides immunity to disturbing voltages which increase with signal amplitude.

摘要： A method and a device for the open-loop and/or closed-loop control of a final controlling element, in particular for influencing the fuel injected into an internal combustion engine, are described. A system deviation is defined starting from a setpoint and an actual value. On the basis of the system deviation, a loop controller specifies a manipulated variable to be received by the final controlling element. If the system deviation lies outside of a range defined by at least two values, a maximum value is specified for the manipulated variable.

摘要： The invention is directed to a measuring arrangement for detecting injection-begin in an internal combustion engine equipped with fuel injection valves. The measuring arrangement includes an inductive position transducer controlled by a current source. The current source is regulated against changes in the level of the supply voltage and elements for stabilization against noise impulses on the supply voltage are provided. The operating point of the output transistor of the current source is regulated in response to sharp drops in the level of the supply voltage thereby obtaining an improved signal-to-noise ratio. The output current of the current source is stabilized with respect to noise by elements of a coupling connected between the base of the output transistor and the supply voltage. By controlling the output current of the current source in dependence upon the rotational speed and/or the amplitude of the output signal of the measuring arrangement, it is possible to obtain an injection-begin signal of constant amplitude over the entire range of the rotational speed, temperature, and fabrication tolerances of the sensors.

摘要： An emergency control apparatus is proposed for a fuel metering system in a Diesel engine, where the signal processing unit (microcomputer) and/or a regulator can be bypassed. In the case of the failure of the signal processing unit, the position signal of the driving pedal is switched more or less directly to the regulator for triggering the control unit for the quantity-determining member, and if there is a failure of the regulator, a purely proportional regulator comes into action. It is thus assured that even in the case of failure emergency operation is guaranteed, the course of which emergency operation can essentially be influenced only by the driver of the vehicle.

摘要： The inductance of a variable inductor is put in series with a resistor to provide a delay circuit at the output of an amplifying path and the delayed voltage is fed-back to produce square waves having a period representative of the induct. The amplifying path includes a first amplifier and a final stage that includes a transistor. A second transistor is connected to a voltage supply line feeding the final stage and the delay network and is also connected to the final stage in such a way that the second transistor conducts when the first transistor of the final stage is blocked and so that the second transistor is automatically blocked when the output of the final stage is at a low potential. The base of the second transistor is connected through a resistance to a battery voltage line at a somewhat higher potential than that of the voltage supply line for the final stage. It is useful to provide an additional amplifier to operate the second transistor with its input coming from the feed back line supplied by the variable inductor and its network resistor, preferably through a low-pass filter. For adjustments that may be necessary when the inductor of a system is replaced, the characteristic curve of the evaluation circuit can be additively shifted by interposing a resistance-capacitance delay followed by an amplifying comparator in the amplifying path, preferably between the preliminary amplifier and the final stage.

摘要： A control apparatus for a fuel metering system including a fuel pump is proposed, where in the case of a Diesel engine with insufficient voltage during starting, the final control element for the governor rod of the fuel pump is uncoupled from the signal processing unit and connected directly to a supply voltage line. It is thereby possible to prevent indefinite output signals of the signal processing unit, which appear in case of insufficient voltage, from having any effect, and simultaneously it is possible to attain reliable starting of the engine.

摘要： A measuring circuit (MS) for measuring the value of an impedance in an impedance network includes an oscillator device (OSZ1), a second oscillator device (OSZ2), a phase-controlled rectifier (PG), a reference/actual value comparison point (AG) and an integrator.The first oscillator device feeds a first alternating voltage of constant amplitude and constant frequency to a first output connection (A1). The second oscillator device feeds a second alternating voltage of the same frequency, but with adjustable amplitude and with phase shifted by 180.degree., to a second output connection (A2). The amplitude of the second alternating voltage depends on the phase of the signal which is transmitted to the phase-controlled rectifier via an input connection (E). If the input signal is in phase with the second output signal, the amplitude of the second output signal is reduced. However, if the input signal oscillates in opposite phase to the second output signal, the amplitude of the second output signal is increased. This change of amplitude is effected by the integrator which integrates the signal, which is rectified and compared with a reference value, and transmits the integration value as amplitude adjusting value.

摘要： An evaluating circuit for linearizing the output signal of a differential-choke displacement transmitter has two inductive coils each supplied with an alternating voltage with constant frequency produced by an oscillator, wherein the amplitude is adjustable and the second alternating voltage is phase-displaced relative to the first alternating voltage by 180.degree.. The signal which is picked up between the inductive coils at the input is compared, after a phase-controlled rectification, with a reference value and the deviation is integrated. With the aid of the integrated signal the regulation of the amplitude adjustment of the alternating voltages is performed. As a result a measuring signal without residual ripple is obtained, which changes proportionally to an adjustment path for example of an adjustment rod.
