    Abstract: A system and method for controlling switching between driving modes of a hybrid electric vehicle are provided. In particular, driving mode switching is performed from an electric vehicle (EV) mode to a hybrid electric vehicle (HEV) mode under a condition in which the fuel injection compensation amount when an engine is first started is minimized The driving mode switching from an EV mode to an HEV mode is performed before gear shift from a lower gear to a higher gear is completed (e.g., before the speed of a motor is reduced) during accelerated driving of the vehicle to minimize the fuel injection compensation amount when an engine is first started, thereby improving fuel efficiency.

    Abstract: A target air amount for achieving a requested torque is back-calculated from the requested torque using a virtual air-fuel ratio. The virtual air-fuel ratio is changed from a first air-fuel ratio to a second air-fuel ratio in response to a condition for switching an operation mode from operation in the first air-fuel ratio to operation in the second air-fuel ratio being satisfied. After the virtual air-fuel ratio is changed from the first air-fuel ratio to the second air-fuel ratio, an interval of time passes and the target air-fuel ratio is then switched from the first air-fuel ratio to a third air-fuel ratio that is an intermediate air-fuel ratio between the first air-fuel ratio and the second air-fuel ratio. The target air-fuel ratio is temporarily held at the third air-fuel ratio, and is thereafter switched from the third air-fuel ratio to the second air-fuel ratio.

    Abstract: A combustion mode transition control for controlling a transition between a homogeneous-charge compression-ignition (HCCI) combustion mode and a spark-ignition (SI) combustion mode includes slowly transitioning intake and exhaust camshafts from initial phase settings corresponding to one of the HCCI and SI combustion modes to target phase settings corresponding to the other of the HCCI and SI combustion modes. An ignition spark timing and an injected fuel mass are coordinated with the transitioning of the intake and exhaust camshaft phase settings to substantially maintain engine load continuity during the transitioning of the intake and exhaust camshaft phase settings.

    Abstract: A control device for an internal combustion engine including a camshaft of the internal combustion engine; a plurality of plane cam shape portions; at least one transitional shape portion; a cam switching mechanism; a cam position sensor; and a control section. The plane cam shape portions, at the camshaft, have valve lift characteristics different from each other, have respective cam faces parallel to a rotation axis of the camshaft, and are spaced apart from each other. The transitional shape portion is between two adjacent ones of the plane cam shape portions and has a curved cam face which connects the cam faces of the two plane cam shape portions. The cam switching mechanism switches between the valve lift characteristics for an intake valve by selecting one of the plane cam shape portions via the transitional shape portion.
