  • Patent number: 8664936
    Abstract: The invention relates to an electronic motor vehicle control system having at least one valve actuating circuit which controls a load current by means of pulse width modulation. The actuating circuit has at least one electronic current measuring circuit which has at least one measurement path with at least one analog/digital converter. The analog/digital converts an analog measurement signal of the load current into a digital measurement signal of the load current and is actuated or designed in such a way as to carry out a plurality of current measurements per PWM period. The at least one measurement path of the current measurement circuit has a signal conservation circuit which provides the analog measurement signal of the load current substantially unchanged, and independent of the actual load current, for at least a defined hold time (toff->on, ton->off).

  • Patent number: 8578258
    Abstract: Disclosed is a method of improving the immunity to interference of an integrated circuit (16) having error signals transferred between a microprocessor chip or multiple processor ?C (1) and an additional component (2). For the transfer, a minimum pulse length that is independent of the clock frequency of the microprocessor or the microprocessors is defined, starting from which a signal on an error line having a defined pulse length is interpreted as an error. Also disclosed is an integrated circuit, which is designed so that the above method is implemented. The circuit has a microprocessor chip or multiple processor microcontroller (1) or microprocessor module and an additional component (2) having separately arranged power elements. The circuit also has pulse extending devices and/or signal delaying devices for the output of error pulses (6, 6?) one after the other through at least one error line (3, 4).

  • Publication number: 20070158607
    Abstract: Disclosed is a method for calibrating, mechanically adjusting, or calculating a drive current of an electromagnetically operable actuator. The actuator controls the flow of a fluid responsive to the differential pressure. The indicator of the influencing of the pressure caused by the actuator can be determined in advance by the intensity of the electric actuation of the actuator even without the use of pressure sensors, with one or more actuator-related characteristic curves, characteristic fields, or parameters KGind for the actuator being taken into account so that via these parameters a nominal flow G can be adjusted in a defined fashion in dependence on the current intensity I, and the actuator-related parameters are established automatically without using pressurizations of the actuator.

  • Publication number: 20070030618
    Abstract: In a method for producing and/or adjusting an electromagnetically controllable actuator which is appropriate to control the flow of a fluid, at least one electromagnetic property of the actuator is measured, and the measured electromagnetic property itself or a quantity derived therefrom is used as an actual value for a control of a correcting variable. This correcting variable is taken into account directly to produce or adjust the actuator. A suitable device for this calibration comprises a control circuit and a mounting location, where the actuator can be mounted into the device, and is designed to adjust at least one mechanical property of the actuator by way of the correcting variable.
