  • Publication number: 20180195449
    Abstract: An internal combustion engine comprises a port injection injector for injecting fuel into an intake port and a direct injection injector for injecting fuel into a combustion chamber. A controller causes the port injection injector and the direct injection injector to inject fuel on the basis of a running condition of the internal combustion engine. Further, the controller increases an injection amount of the direct injection injector above a normal injection amount of the direct injection injector when the internal combustion engine decelerates, thereby reducing the fuel pressure of the direct injection injector rapidly.

  • Publication number: 20180175669
    Abstract: When a vehicle approaches a parking space, a ground controller excites a power transmission coil using an excitation pattern signal containing identification data, and a vehicle controller acquires the identification data from the excitation pattern signal received by at least one of subcoils. Then, a communication unit transmits the acquired identification data to the ground unit. The ground controller pairs the power transmission coil and the power reception coil with each other when the identification data contained in the excitation pattern signal and the identification data transmitted from the vehicle controller match each other. Also, the pairing is canceled if the identification data received by the subcoil provided on the front side and the identification data received by the subcoil provided on the rear side are different from each other.

  • Patent number: 10000205
    Abstract: A fail-safe control device is provided for hybrid vehicles which allows a travel distance of a vehicle to be extended in an event of an ON-failure of a second clutch. An integrated controller switches between an HEV mode and an EV mode by controlling a first clutch between an engine and a motor, and a second clutch between the motor and a continuously variable transmission. The integrated controller prohibits the transition from the HEV mode to the EV mode when a clutch failure determination unit detects an ON-failure of the second clutch while the vehicle is traveling in the HEV mode.
