摘要： Method in which the current is measured inside an integrated PWM control circuit using at least one A/D converter which is likewise integrated in the circuit, wherein the PWM controller is provided for the purpose of driving inductive loads and is arranged, in particular, in an electronic circuit of an electronic controller for a motor vehicle braking system, in which, before determining the actual current of the PWM controller, which is determined using the at least one A/D converter, the current is smoothed using a low-pass filter. The invention also describes a circuit arrangement for carrying out the above method and its use in electronic motor vehicle control systems.

摘要： The invention relates to a method for the calibration or mechanical adjustment, or calculation of a drive current for a solenoid-powered actuator for adjustment of the pressure-differential dependent flow of a fluid. The scale of the pressure effect generated by the actuator can be determined in advance by means of the strength of the electrical drive for the actuator, even without the use of pressure sensors, whereby one or more actuator-specific calibration curves or constants KGind for the actuator are derived, such that a set flow (G) can be specifically achieved using said constants by adjustment with the strength of the current (I). The actuator-specific constants are automatically determined without the use of pressurising the actuator. The method can be used to control solenoid valves for ABS vehicle braking systems. Said solenoid valves are intrinsically configured to fully open and close, but can be given corresponding regulatory functions by means of the control system.

摘要： The invention relates to a method and circuit for determining the magnetic flux in at least one inductive component (1), which can be electrically driven with a drive signal (6) via an electronic drive or a driver stage (3), by evaluating and setting a measurement signal, induced by the magnetic flux of the inductive component, by means of an electronic measuring device (4). According to said invention, the measurement signal (5), which is measured at the inductive component and depends on the magnetic flux thereof, is actively maintained at a substantially constant value by the measuring device or electronic drive or driver stage (3) and the time (t1, tc) is determined, during which the drive signal, acting upon the inductive component with production of the measurement signal, is triggered.

摘要： The invention relates to a method and a device for producing and/or adjusting an electromagnetically controllable actuator that is suitable for regulating the flow of a fluid, said actuator comprising an electromechanical arrangement that can be controlled by means of an excitation coil (9) and has a mobile armature (6). The electromechanical arrangement acts mechanically on a valve actuation device for opening and closing the actuator. Said valve actuation device comprises at least one closing element (5), a resetting element (27) for opening or closing the closing element when the excitation coil is not excited, and a valve seat (4) in which the closing element for opening or closing the actuator engages. According to the invention, at least one electromagnetic characteristic of the actuator is measured, and the measured electromagnetic characteristic itself or a variable derived therefrom is used as an actual value for the regulation of an adjustment variable. Said adjustment variable is directly used to produce or adjust the actuator.

摘要： The invention relates to an electronic motor vehicle control system having at least one valve actuating circuit (2a, 2b) which controls a load current by means of pulse width modulation, and having at least one electronic current measuring circuit which has at least one measurement path (1, 3) with at least one analog/digital converter (13, 33) which converts an analog measurement signal of the load current into a digital measurement signal of the load current and which is actuated or designed in such a way as to carry out a plurality of current measurements per PWM period, wherein the at least one measurement path (1, 3) of the current measurement circuit has a signal conservation circuit (12, 32) 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 (t
off->on , t
on->off ).
