摘要： An internal combustion engine control apparatus can reliably detect abnormality in a crank angle position signal to ensure a fail safe function upon occurrence of the abnormally. A fuel injection signal and an ignition signal is generated based on the result of cylinder identification performed by a cylinder identification part and the crank angle position of the crank angle position signal. An abnormality determination part determines whether the crank angle position signal is abnormal. The cylinder identification part includes a cylinder identification resetting part for resetting the current content of the cylinder identification performed by the cylinder identification part upon determination of abnormality. The cylinder identification resetting part includes a fuel injection and ignition signal stopping part for stopping the fuel injection signal and the ignition signal, and a cylinder identification information clearing part for clearing previous cylinder identification information earlier than the last crank angle position signal upon determination of abnormality.

A second DC/DC converter is of a constant current control type and is controlled so as to keep input current or output current at predetermined target current. A control circuit determines an optimum target value of electric generation bus voltage, based on different algorithms, in accordance with all or some of modes A to C which are classified by the charging/discharging condition of a second electric storage device, and controls the first DC/DC converter so that the electric generation bus voltage becomes the determined target value.

摘要： When an estimated charging rate of an electric storage device is lower than a target rate, and a regenerative power generation controller performs power-generation control of an electric power generator when the speed of a vehicle is being reduced and fuel supply to an engine is stopped, a regenerative charging amount predictor predicts a regenerative charging rate in accordance with vehicle speed, as the vehicle speed is being reduced, and the target charging rate of the electric storage device is decreased as the regenerative predicted charging amount increases. The regenerative power generation controller limits a power-generation amount toward reduction in such a way that in the electric power generator, a difference between torque required for power generation when the electric storage device is charged and torque required for power generation when the electric storage device is not charged falls within a predetermined torque difference.

摘要： The fuel supply system of an internal combustion engine includes an electronic control unit (ECU) for transferring the engine from a state in which a high-pressure fuel pump does not deliver any pressurized fuel to a state in which the high-pressure fuel pump begins to deliver the pressurized fuel by gradually varying an output period of a drive signal for controlling opening/closing behavior of a solenoid valve while monitoring changes in fuel pressure detected by a pressure sensor, and for estimating a mounting error between angular mounting positions of the high-pressure fuel pump and a pump actuating cam with reference to a rotation signal from a state of the solenoid valve drive signal when a change in the fuel pressure has been detected. The solenoid valve drive signal is corrected based on the value of the mounting error estimated by the ECU.
