Patent ID: 7758467

Claim:
A hybrid vehicle control apparatus comprising: an engine; a transmission including at least one torque transmitting path that transmits power through a one-way clutch; a motor/generator arranged between the engine and the transmission; a first clutch with a variable torque transmission capacity being disposed between the engine and the motor/generator; a second clutch with a variable torque transmission capacity being disposed in a power train that spans from the motor/generator to a drive wheel via the transmission; and a controller configured to disengage the first clutch and engage the second clutch to select an electric drive mode in which the engine is stopped and the drive wheel is driven solely with power from the motor/generator, and to engage both the first and second clutches to select a hybrid drive mode in which the drive wheel is driven with power from both the engine and the motor/generator, the controller being further configured to execute a rotational speed control of the motor/generator while in a coasting state with the transmission in the torque transmitting path that transmits power through the one-way clutch such that the rotational speed control increases a rotational speed of an input side of the one-way clutch to a value closer to a rotational speed of an output side of the one-way clutch with a difference between the rotational speeds of the input and output sides of the one-way clutch becoming equal to a target value.
