Patent ID: 8682544

Claim:
A vehicle, comprising: an internal combustion engine configured to output power via a clutch to a driveshaft linked to driving wheels; a motor configured to input and output power from and to the driveshaft; a transmission that has an input shaft connected via the clutch to an output shaft of the internal combustion engine and connected with a rotating shaft of the motor and transmits power between the input shaft and the driveshaft with a speed change between different speeds; an accumulator configured to transmit electric power to and from the motor; and a controller configured to, in a case of a predetermined stop request time that is when operation stop of the internal combustion engine is requested while the internal combustion engine is in operation with the clutch engaged at a higher rotation speed than a resonance rotation speed band that is a rotation speed range of the internal combustion engine where resonance occurs in the vehicle, control the internal combustion engine, the motor, and the clutch so that the clutch is disengaged and the vehicle is driven with a driving force demand required for driving the vehicle while keeping a rotation speed higher than the resonance rotation speed band in the internal combustion engine, and subsequently control the internal combustion engine, the motor, and the clutch so that the rotation speed of the internal combustion engine is lowered below the rotation speed band by partially engaging the clutch and stopping fuel injection into the internal combustion engine and the vehicle is driven with the driving force demand after a rotation speed of the motor reaches less than or equal to a predetermined rotation speed as a rotation speed lower than the resonance rotation speed band, wherein the controller controls the transmission, in a case that the rotation speed of the motor becomes less than or equal to the predetermined rotation speed if the speed in the transmission is changed to a higher speed level that is a higher speed than a present speed in the transmission in the case of the predetermined stop request time, so that the speed in the transmission is changed to the higher speed level after the clutch is disengaged.
