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 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.

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 management server performs a process including: when there is a request to partially replace a battery, obtaining a usage history of the battery; obtaining each cell's full charge capacity; determining a cell having a smallest full charge capacity as a cell to be replaced; calculating an average value of the full charge capacities of the plurality of cells excluding the cell to be replaced; extracting a selectable cell from inventory information; selecting a replacement cell; setting a replacement fee corresponding to partial replacement; and when entire replacement is requested, setting a replacement fee corresponding to entire replacement.

Abstract: When it is determined that a negative pressure is insufficient, an EGR-close control is executed so that an EGR valve is driven toward a close position to increase the negative pressure in an intake passage. After that, it is determined whether the negative pressure detected by a pressure sensor is restored to a specified target negative pressure. When the negative pressure is not restored to the target negative pressure even when a specified time period has elapsed after it is determined that the negative pressure is insufficient, an automatic brake unit executes a braking-force assist control to assist a braking force of a brake. A shortage of the braking force due to an insufficient negative pressure is compensated by the braking force generated by the automatic brake unit.
