  • Patent number: 9682695
    Abstract: A vehicle control apparatus controls a vehicle including an internal combustion engine, a power generation unit that converts at least one of an engine output of the internal combustion engine and a kinetic energy of the vehicle into electric power, and a power storage unit that stores the electric power. The vehicle control apparatus includes: a first control unit configured to control the vehicle to alternate repeatedly between acceleration travel, in which the vehicle accelerates using the engine output, and coasting travel, in which the vehicle coasts without using the engine output, such that a vehicle speed is maintained within a predetermined speed region; and a second control unit configured to control the power generation unit to convert at least one of the engine output and the kinetic energy into electric power during a coasting period in which the vehicle performs the coasting travel.

  • Publication number: 20160101681
    Abstract: A driving device includes: a power distribution mechanism configured such that a ring gear is connected to an internal combustion engine, a sun gear is connected to a first MG, and a carrier is connected to a counter shaft in a power transmittable manner; and a clutch mechanism that is able to connect the sun gear to the ring gear. The internal combustion engine, the first MG, the power distribution mechanism, and the clutch mechanism are placed on the same axis. The clutch mechanism is placed on an opposite side to the internal combustion engine across the first MG and the power distribution mechanism.
