摘要： An electronic control unit that calculates an injection standby period, which is a period from an energization start point of the solenoid to a point at which the fuel injection valve opens, and adjusts an energization period of the solenoid in accordance with the calculated injection standby period. The electronic control unit of the control apparatus for a fuel injection valve then measures a reference fall detection period, which is a period from the energization start point to a reference fall detection point, and sets the injection standby period to be longer as the reference fall detection period is longer. Here, the reference fall detection point is a point at which the excitation current detected by the current detection circuit falls below a reference current value, which is smaller than a peak current value, while the excitation current decreases after reaching the peak current value.

摘要： During a catalyst rapid warm-up at a time of a cold start of an engine, a fuel is injected by a required injection quantity through a multi-stage injection consisting of a fuel injection by a full lift injection during an intake stroke and a fuel injection by a partial lift injection during a compression stroke. In a case where a deterioration of a combustion state is confirmed, a correction for increasing the required injection quantity, which is to enrich an air-fuel ratio, is performed. At a time of the enriching quantity increase, a sum of injection quantities of the multi-stage injection is increased by the amount of the correction for increasing the required injection quantity without the injection quantity and an injection timing of the fuel injection by the partial lift injection being changed from a base time.

摘要： A controller for a vehicle includes a controlling unit. In a case in which the target engine torque is less than or equal to a threshold, the controlling unit controls the engine such that the torque of the engine becomes equal to the target engine torque, and controls a motor-generator such that the torque of the motor-generator becomes equal to the target motor torque. Also, in a case in which the target engine torque is greater than the threshold, the controlling unit controls the engine such that the torque of the engine becomes less than or equal to the threshold, and controls the motor-generator such that the torque of the motor-generator increases.

摘要： A fuel injection control device divides an amount of fuel corresponding to an injection amount required for a single combustion into portions corresponding to multiple fuel injections, causes the direct injector to inject the fuel in the multiple times, and causes the direct injector to execute a partial-lift injection as a final fuel injection. The device includes a total injection amount calculation section, an individual injection amount calculation section, and an injection amount changing section. The injection amount changing section executes, as a first changing process, a process for increasing the injection amount at the final fuel injection to a value between a partial-lift injection lower limit value and a partial-lift injection upper limit value and reducing the injection amount at a fuel injection other than the final fuel injection by the increased amount of the injection amount at the final fuel injection.
