摘要： There is proposed a control unit for an internal combustion engine, which comprises a boost circuit, a switching element, a current detecting resistor and a controller and is designed to be actuated such that the boost circuit is used to boost a power source voltage to create a boosted voltage and the controller is used to control the switching element so as to enable the boosted voltage to flow to the injector solenoid coil. This control unit is designed such that, when the boost circuit goes out of order, the injector solenoid coil is excited by making use of the power source voltage without using the boosted voltage and without creating a peak current to thereby generate a first holding current required for opening the injector and a second holding current required for retaining the opened state of the injector, the second holding current being lower in intensity than the first holding current.

摘要： According to the present invention, the operation of a diagnostic circuit within a load drive circuit, which has been built into an electronic control device, is checked without modifying the electronic control device or the like. The load drive circuit, which drives a load such as a solenoid using a DC power supply as a power supply, includes a drive circuit and a diagnostic circuit which is independently provided within the drive circuit. Upon input of a drive-stop signal from a control circuit that controls the drive circuit, the operation of at least the drive circuit stops, so that whether the diagnostic circuit, which diagnoses the condition of the load, is normally operating or not is checked in a condition in which the load drive circuit has been built into the electronic control device.

摘要： An internal combustion engine controller comprises a booster coil connected to a battery and a booster capacitor. A switch element is connected to the booster coil to control the passage of current through the booster coil and an interruption of the current. The booster capacitor accumulates electrical energy generated with an inductance of the booster coil at the time of the interruption of the passage of the current. A booster control circuit carries out control in a constant boost switching cycle so as to pass the current through the booster coil and the switch element until the current reaches a preset switching stop threshold value and then interrupt the current to charge the energy generated with the inductance of the booster coil into the booster capacitor. The booster control circuit is configured to ensure a minimum time period for the booster capacitor-charging of the energy within the boost switching cycle.
