Abstract: An actuator operation amount setting unit prepares the rotational speed command value for an electric motor such that the phase of an intake valve changes in accordance with the target phase. An electric-motor EDU controls the motor supply electric power such that the electric motor operates in accordance with the rotational speed command value. An overheating determination unit determines whether at least one of the electric motor and the electric-motor EDU needs to be restricted from heating up based on a result of comparison between the information indicating the motor supply electric power and the reference value. A rotational speed command value restriction unit restricts the rotational speed command value provided to the electric-motor EDU to a value within a predetermined range, when it is determined that the at least one of the electric motor and the electric-motor EDU needs to be restricted from heating up. A reference value setting unit variably sets the reference value based on the rotational speed of the electric motor.

Abstract: An intake valve phase setting unit sets the target valve phase used in the variable valve timing control based on the engine operating state, and a control target value setting unit sets the control target value based on the target valve phase. An actuator operation amount setting unit prepares the rotational speed command value for an electric motor that serves as an actuator of a variable valve timing system based on the deviation of the current value from the control target value. A phase change rate control unit sets the rate of change in the valve phase to a lower value when the variable valve timing control moves the valve phase away from the reference phase (the phase when the engine is idling) at which combustion takes place stably in engine than when the variable valve timing control causes the valve phase to the reference phase.

Abstract: A current value of an intake valve phase calculated based on a sensor output is smoothed along the direction of time axis in accordance with a smoothing factor, whereby a phase detection value is detected. At the time of reference position learning, the smoothing factor is set to a value larger than at the time of normal control, so that the degree of smoothing in the smoothing process of phase detection value becomes smaller. Therefore, it is possible to detect more quickly that the intake valve timing has reached the reference timing at the time of reference position learning based on the phase detection value, than when a common smoothing factor is set both for the normal control and for the reference position learning.

Abstract: A high-pressure fuel supply system is suitable for an internal combustion engine having an in-cylinder injector for injecting a fuel into a cylinder. The high-pressure fuel supply system includes a high-pressure fuel pump driven by an engine, a high-pressure delivery pipe supplying the fuel from the high-pressure fuel pump to the in-cylinder injector, and an actuation valve provided with a leakage function provided between the high-pressure fuel pump and the high-pressure delivery pipe. An amount of leakage in the actuation valve provided with the leakage function is set to an amount not smaller than a discharge amount of the high-pressure fuel pump.
