[0057] "First Embodiment"

[0058]

[0059] figure 1 It is a block diagram showing the overall structure of the power unit PU of the vehicle.

[0060] Such as figure 1 As shown, the power unit PU mounted on the vehicle (hybrid motor vehicle) includes a battery 11, a first converter 12, a first power drive unit 13, an electric motor 14, an internal combustion engine 15, a generator 16, a second power drive unit 17, and an electric The compressor 18, the electric heater 19, the second converter 20, the low-voltage battery 21, the charging device 22, the external charging plug 23, and the control device 30. Here, the internal combustion engine 15, the generator 16, and the second power drive unit 17 constitute an auxiliary power unit S that generates electric power by the driving force of the internal combustion engine 15.

[0061] The storage battery 11 is, for example, a lithium ion (Li-ion) secondary battery, and can be charged and discharged.

[0197] "Second Embodiment"

[0198]

[0199] Next, the power unit PU of the second embodiment will be described. The overall structure of the power unit PU of the second embodiment is the same as the power unit PU of the first embodiment (refer to figure 1 ) Are the same, so the description is omitted.

[0200]

[0201] Next, the operation mode determination processing of the power unit PU of the second embodiment (refer to figure 2 )Be explained. The control device 30 of the power unit PU of the first embodiment and the second embodiment figure 2 In step S27 of, limit processing (power generation limit processing) is performed on the generator power generation output PREQGEN calculated in step S26. Here, the power generation limit processing of the first embodiment is Image 6 "Power generation limit processing (upper limit value)" shown. In contrast, the power generation limit processing of the second embodiment is Picture 9 The "power generation amount limit processing (lower

[0222] "Third Implementation Mode"

[0223]

[0224] Next, the power unit PU of the third embodiment will be described. The overall structure of the power unit PU of the third embodiment is the same as the power unit PU of the first embodiment (refer to figure 1 ) Are the same, so the description is omitted.

[0225]

[0226] Next, use Picture 11 The operation mode determination processing of the power unit PU of the third embodiment will be described. Picture 11 It is a flowchart of the operation mode determination processing of the power unit PU of the third embodiment.

[0227] Operation mode determination processing of the first embodiment (refer to figure 2 ) Calculate the amount of power generated by the generator 16, that is, the generator output PREQGEN (see step S26), and limit the generator output PREQGEN (see step S27), and then obtain the rotational speed of the internal combustion engine 15, that is, the generator The engine rotation speed NGEN (refer to step S28).
