  • Patent number: 10760533
    Abstract: A detecting unit that detects a specific pressure difference between a pressure of gas that has passed throuch a canister and a pump and a pressure of the gas before passing through the canister and the pump. A gas flow rate from the pump may be higher with a smaller pressure difference between upstream and downstream sides relative to the pump, and higher with a higher purge gas density. A gas flow rate from the canister may be lower with a smaller pressure difference between upstream and downstream sides relative to the canister, and lower with a higher purge gas density. An estimating unit may estimate a flow rate of the purge gas while the specific pressure difference is an unchanged pressure difference being a pressure at which the flow rate of the gas is not chanced by the density of the purge gas.

  • Publication number: 20200173382
    Abstract: An evaporated fuel processing device includes a canister; a purge passage connecting the canister and an intake pipe of an engine; a purge control valve on the purge passage; and a controller that controls switching timings for the purge control valve and a fuel injection valve that supplies fuel to the engine. The controller estimates whether a catalyst temperature would exceed a criteria temperature if the purge gas is supplied to the engine while the engine is in operation and a fuel supply from the fuel tank to the engine is stopped, and in a case where the catalyst temperature is estimated to exceed the criteria temperature, the controller reduces the purge gas amount before the fuel supply to the engine is stopped such that the catalyst temperature becomes equal to or lower than the criteria temperature when the fuel supply to the engine is stopped.

  • Patent number: 9505398
    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.

  • Patent number: 9499159
    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.

  • Patent number: 9151233
    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.
