Abstract: A hybrid vehicle includes a plurality of motor generators and an engine for generating a vehicle-driving force. A motor ECU controls the motor generators in accordance with respective torque command values for the motor generators. The motor ECU selects a motor generator used for performing vibration-reduction control, based on the operating state of the motor generators each. The output torque of the motor generator used for the vibration-reduction control is controlled so that a compensation torque corresponding to a periodic vibration-reduction torque component for cancelling out a periodic variation component of the rotational speed of drive wheels is superimposed on the torque for generating the vehicle-driving force.

Abstract: In the case that operation stop of the engine is requested while the clutch is engaged and the engine is driven at a higher rotation speed than the resonance rotation speed band, the clutch is disengaged and the engine is driven in the self-sustaining operation at the self-sustaining rotation speed higher than the resonance rotation speed band, the rotation speed Ne of the engine is lowered less than or equal to the second rotation speed Nref2 lower than the resonance rotation speed band with stop of fuel injection into the engine and the partially-engaged clutch after the rotation speed Nm of the motor MG becomes less than or equal to the first rotation speed Nref1 predetermined as a rotation speed lower than the resonance rotation speed after the clutch is disengaged. The rotation speed of the engine is therefore enabled to pass more rapidly through the resonance rotation speed band.

Abstract: A crankshaft of an engine, an output shaft of a first electric motor, and an output shaft of a second electric motor are directly or indirectly connected to each other mechanically. When the engine is started, a vibration reduction torque is caused to act on the crankshaft that is set in the form of a periodic torque based on the crank angle, so that torque pulsation of the engine is suppressed. The output torque of the first electric motor is controlled in accordance with the sum of a motoring torque and a part of the vibration reduction torque. The output torque of the second electric motor is controlled in accordance with the sum of its essential output torque for causing the vehicle to travel and a torque for compensating for a shortage of the vibration reduction torque that occurs because a part of the vibration reduction torque is output from the first electric motor.

Abstract: A vehicle includes a converter for stepping up power provided from a power storage device, and an inverter for converting the power output from converter and outputting it to an alternating-current motor for driving the vehicle. In the vehicle, a rectangular voltage control unit controls the inverter by means of rectangular wave voltage control that is based on a torque command value and the like, so as to control an output torque of the alternating-current motor. A system voltage control unit controls a system voltage, which is an output voltage of the converter. The system voltage control unit lifts a restriction on a system voltage command value based on an accelerator pedal position and the like, and then increases it. When increasing the system voltage command value during the rectangular wave voltage control for the inverter, a cooperative control unit increases the system voltage command value and the torque command value in a cooperative manner.

Abstract: During execution of an auto cruise function, in response to selection of a power mode, when an measured accelerator opening Acc is less than a preset opening Accref, a hybrid vehicle of the invention sets a power mode cancellation flag Fpmc to 1 and a power mode enabling flag Fpm to 0 (steps S540 and S550). This prohibits the use of an accelerator opening setting map in the power mode for execution of the auto cruise function. In the power mode, in response to an instruction for enabling the auto cruise function, the hybrid vehicle keeps the power mode enabling flag Fpm to the setting of 1 (step S560) as long as the measured accelerator opening Acc is not less than the preset opening Accref. This allows the use of the accelerator opening setting map in the power mode for execution of the auto cruise function.
