  • Patent number: 5975059
    Abstract: A method and a device for the closed-loop control of a control element having integral action, particularly an injection-timing device of a high-pressure fuel pump. Using a system deviation as a baseline, a controller preselects a driving signal to be applied to the control element. In the event of an error in the area of actual-value ascertanment, an emergency travel operation is initiated. A signal is applied to the control element, such that at least short-term, it assumes a defined position.

  • Patent number: 5880920
    Abstract: A method and an apparatus for controlling an electromagnetic switching member having an excitation winding and a movable armature.

  • Patent number: 5757085
    Abstract: A motor vehicle immobilization system having an anti-theft control device (13) and a function control device (10, 11) which is released by a regular unlocking communication with the anti-theft control device (13). To permit simple maintenance of individual engine function units, the function control device (10, 11) has bypass means (204 through 220) which permit an atypical unlocking of the function control device (10, 11) by the external device (19). The bypass means (204 through 220) include a time-delay device (206, 218) which, during atypical unlocking, only releases the function control device (10, 11) after the passage of a predetermined delay time (T.sub.F).

  • Patent number: 5755209
    Abstract: A system is provided for controlling a fuel-metering device, for a diesel engine. First means generate a first signal for triggering a first actuating means (115) for establishing the start of pump delivery and the end of delivery. Second means generate a second signal for triggering a second actuating means (125) for establishing the delivery rate. In this case, a signal characterizing the start of pump delivery is taken into consideration by the second means.

  • Patent number: 5653210
    Abstract: 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.

  • Patent number: 5583383
    Abstract: A vehicle security system with an anti-theft controller which conducts a data exchange with at least one function controller, particularly an engine controller, in order to control its operational readiness, wherein the data exchange is conducted via a data line connecting at least the anti-theft controller and the function controller. Alternatively, an external device (4) can be connected to the data line (1), with the device being configured for the exchange of data with at least one of the controllers (2, 3, 3', 3") The data line is a line which is already in existence in the vehicle, particularly a K-diagnostics line and/or an L-diagnostics line in accordance with ISO standard 9141. For the control of the data exchange, one of the controllers (2, 3) connected via the data line (1) exercises the functions of the control unit.

  • Patent number: 5444381
    Abstract: 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.
