    摘要： In an automotive engine control apparatus used for a multi-cylinder engine where both an injection coil and an ignition coil are employed with each of multiple cylinders, abnormal states are systematically detected, while an injection system is mutually interconnected with an ignition system as to these abnormal states. The injection coils are driven via a first switch element by a microprocessor, and injection operations of these injection coils are monitored by a first detection circuit. The ignition primary coils are driven via a second switch element by the microprocessor, and ignition operations of these ignition coils are monitored by a second detection circuit. The microprocessor controls drive stopping means to perform a turn-out drive operation such that this drive stopping means stops both a fuel injection operation and an ignition operation of an abnormal-operated cylinder with respect to an abnormal state occurred in either the injection system or the ignition system. Also, abnormal-state storage operation by abnormal state storage means separatedly provided for the injection system/ignition system/cylinder system, which is derived from stopping of the drive operations, is prohibited by storage prohibiting means.

    摘要： A controller for cylinder injection type injectors is constructed so that current detection element for detecting currents flowing through injector coils are inserted between a connection point of first switching element and the nodes of reverse current blocking diodes and current commutation diodes, respectively, and over-current detection element do not include circuits for temporarily interrupting over-current detection operations based on output signals of over-excitation signal generation element. That is, the current detection element are arranged at paths not admitting the flow of over-excitation currents, so that power dissipations at the current detection element can be reduced. Further, the circuits for temporarily interrupting the operations of the over-current detection element while over-excitation currents are being supplied are dispensed with. As a result of these arrangements, the present invention can provide a small-sized, lightweight and inexpensive controller capable of detecting over-currents in a wide range.

    摘要： An inexpensive and small-scale fuel injector control system having a number of fuel injector driving circuits smaller than the corresponding number of driven fuel injectors, in a cylinder injection type internal combustion engine having cylinders that are distanced by two strokes with respect to fuel injection timing and where no overlap occurs in the fuel injection timing. One of the ends of each of the coils of plural injectors, for the cylinders that are distanced from each other by two strokes in the fuel injection timing without overlapping each other, are simultaneously connected to an output terminal of a driving circuit, while the other ends of the coils are connected, respectively, to switching means that are turned on or off at energization/deenergization timings of coils of the fuel injectors.

    摘要： An electrical load is supplied with power from a driving power source, and a microprocessor (CPU) controls the opening/closing current supply rate (duty factor) of an opening/closing element in accordance with target current and driving power source voltage so that open loop control is carried out to achieve predetermined target current. The voltage between both the ends of a current detecting resistor connected to the ground side of the opening/closing element is input as a monitoring voltage from a current detecting amplifying circuit portion through a multichannel AD converter to CPU. When the error between the comparison target voltage corresponding to the target current and the monitoring voltage is above a first permissible error, CPU judges that there is an abnormality sign, and if the error is above a larger second permissible error, CPU judges that there is appearing abnormality. Accordingly, an abnormality sign of a semi-wire-breaking/semi-short-circuit state of the electrical load can be sensed, and abnormality notification can be carried out.

    摘要： A signal voltage, which a variable analog signal source generates, is inputted to a microprocessor via a gain adjustment circuit, a switched capacitor filter circuit, and an analog comparison circuit. The microprocessor that cooperates with a program memory generates a control signal pulse train of a variable period and a variable duty. Filter characteristics are adjusted with a period of the control signal pulse trains CNTa and CNTb, and gain is adjusted with a pulse duty. Even if a comparison reference voltage of the analog adjustment circuit is a fixed value, it is possible to make virtual change and adjustment of a comparison reference voltage by adjusting a gain of the gain adjustment circuit. As a result, it is possible to provide an analog input signal processing circuit capable of individually adjusting input filter characteristics and input gain.
