Abstract:
1. A hybrid vehicle driven by a power unit, the 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 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; and 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 therebetween, 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, 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 and the second 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; a capacitor configured to exchange an electric power between the first rotating machine and the second rotating machine, the vehicle comprising: a state detector that detects a charge state of the capacitor; a controller that controls the power unit, wherein the controller controls the output of the power engine, based on a remaining capacity of the capacitor when driving the power engine in order to start the hybrid vehicle.
