Title:
HYBRID VEHICLE
Document Type and Number:
WIPO Patent Application WO/2011/045966
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; a capacitor; and a transformer for boosting the output voltage of the capacitor. The hybrid vehicle is provided with: a required voltage derivation unit for deriving the required voltages required by each of the first rotary machine and the second rotary machine, in accordance with the operating state; a boost execution determination unit for determining that a boost operation is to be performed by means of the transformer when at least one of the required voltages is greater than a first threshold value; and a control unit for controlling the transformer according to the determination result of the boost execution determination unit. It is therefore possible to achieve greater compactness and reduced costs, and it is also possible to improve the drive efficiency.
