HYBRID VEHICLE

Document Type and Number:

WIPO Patent Application WO/2011/045965

Kind Code:

A1

Abstract:

Disclosed is a hybrid vehicle driven by means of a power unit which is provided with: a first rotary machine comprising a first rotor, a first stator and a second rotor, and in which the number of magnetic poles occurring in an armature row of the first stator and the first rotor or the second rotor are connected to a drive shaft; a motor whereof an output shaft is connected to the other of the first and second rotors; a second rotary machine; and a capacitor. The hybrid vehicle travel modes include: an EV travel mode for travel by means of only the drive power from the first and/or second rotary machine, and an ENG travel mode for travel by means of the drive power from the motor. The hybrid vehicle is provided with an EV travel mode prediction unit for predicting a switch from the ENG travel mode to the EV travel mode, and a control unit for controlling changes in the capacitor residual capacitance target according to the prediction result provided by the EV travel mode prediction unit. It is therefore possible to achieve greater compactness and reduced costs, and it is also possible to improve the drive efficiency.
