Hybrid vehicle

A hybrid vehicle driven by a power unit comprising:

• a first rotating machine comprising:
• a first rotor comprising a magnetic pole row arranged in a circumferential direction, wherein the magnetic pole row has a plurality of magnetic poles and the adjacent magnetic poles have different polarities;
• a first stator disposed to face the first rotor in a radial direction and comprising an armature row comprising a plurality of armatures arranged in the circumferential direction, wherein a rotating magnetic field moving in the circumferential direction is generated by a change in magnetic poles generated by the plurality of armatures;
• a second rotor disposed between the first rotor and the first stator and comprising a plurality of soft magnetic material elements arranged in the circumferential direction with a gap between the soft magnetic material elements,
• wherein the ratio between the number of magnetic poles generated by the armature row of the first stator, the number of magnetic poles of the magnetic pole row of the first rotor, and the number of the soft magnetic material elements of the second rotor is set to 1:m:(1+m)/2 (m≠1) and one of the first rotor and the second rotor is connected to a drive shaft;
• a power engine, wherein an output shaft of the power engine is connected to the other of the first rotor;
• a second rotating machine configured to exchange a motive power with the drive shaft and to exchange an electric power with the first rotating machine;
• and
• a capacitor configured to exchange an electric power between the first rotating machine and the second rotating machine,
• the hybrid vehicle comprising:
• a traveling condition determining unit that determines a traveling condition of the hybrid vehicle;
• and
• a controller that controls a remaining capacity of the capacitor in accordance with the traveling condition of the hybrid vehicle so as to change a target value of the remaining capacity.
