  • Patent number: 9156461
    Abstract: A control unit for a vehicle, which comprises an engine, a driving motor, an engaging/disengaging device, and a voltage raising device, includes a switching control unit and a voltage raising control unit controlling the voltage raising device. The switching control unit switches between a first driving mode in which the vehicle is driven by a driving force of the driving motor with the engaging/disengaging device released and a second driving mode in which the vehicle is driven by the driving force of the engine with the engaging/disengaging device engaged. In a case where a driving mode is switched from the first driving mode to the second driving mode, the switching control unit starts an engagement of the engaging/disengaging device and switches the driving mode to the second driving mode, after the voltage raising control unit starts the voltage raising control in the first driving mode.

  • Patent number: 8862376
    Abstract: A cruising distance calculation apparatus for a hybrid vehicle that includes a motor and an engine for driving a generator is disclosed. The cruising distance calculation apparatus includes a traveling mode decision unit that decides in which one of traveling modes the vehicle is traveling, the traveling modes including at least EV traveling mode and series traveling mode, an electricity consumption calculation unit that calculates, when the traveling mode is the EV traveling mode, an electric power consumption amount Ec of the battery based on electric power consumption of the battery whereas the electricity consumption unit calculates, when the traveling mode is the series traveling mode, the electric power consumption amount Ec based on output power of the motor, an electric mileage calculation unit that calculates an electric mileage Eef, and a cruising distance calculation unit that estimates a first cruising distance Dp1.
