Abstract: A vehicle control apparatus uses a travel mode selection unit to select between an EV travel mode, an engine travel mode, and an engine generation mode depending on comparisons between an engine generated power cost, an EV effect, and a surplus electric energy. In such manner, according to a travel condition of a vehicle, an appropriate travel mode is selected for an improvement of fuel consumption efficiency. The vehicle control apparatus also computes a fuel consumption decrease or a fuel consumption increase for each of a plurality of travel modes based on an engine efficiency and an MG-INV efficiency. In such manner, fuel consumption increase/decrease for every travel mode may be computed.

Abstract: A vehicle control apparatus computes a fuel consumption decrease or a fuel consumption increase for each of a plurality of travel modes. The vehicle control apparatus includes a control section that calculates an engine efficiency of an engine and an MG-INV efficiency which is a combined efficiency of a motor generator and an inverter. The engine efficiency is calculated based on an engine power and an ideal fuel consumption line. The MG-INV efficiency is calculated based on an MG power. As such, based on the engine efficiency and the MG-INV efficiency, the control section computes the per-unit-electric-power fuel consumption decrease or the per-unit-electric-power fuel consumption increase.

Abstract: A vehicle controller performs a throttle-valve-late-close control in which the throttle valve is held open until a delay time has passed after the fuel cut is started, and an EGR-valve-open-close control in which the EGR valve is repeatedly opened and closed. Then, the throttle valve is closed and the EGR valve is opened. In a period from a latter period of an exhaust stroke to a preceding period of an intake stroke, a valve-overlap control is executed so that a variable valve timing controller is controlled to make both an intake valve and an exhaust valve opened. A pumping loss of an engine is sufficiently reduced and an energy-regenerate efficiency can be effectively improved.
