[0025] <Regarding the devices disposed under the floor panel 100> FIG. 7 is a schematic view in a top view of the vehicle looking down on the plug-in hybrid vehicle 1 from above, similar to FIG. 5. FIG. 7 schematically shows the arrangement of the devices disposed under the floor panel 100. In FIG. 7, the plug-in hybrid vehicle 1 is divided into a region RA on the right side of the vehicle and a region LA on the left side of the vehicle with a center line CL indicating the center in the vehicle width direction of the plug-in hybrid vehicle 1 as a boundary.

[0026] The battery 50 is disposed so as to span both the region RA on the right side of the vehicle and the region LA on the left side of the vehicle. The battery 50 is disposed closer to the left side of the vehicle. As a result, the center of gravity position 51 of the battery 50 is located in the region LA on the left side of the vehicle. That is, the battery 50 is disposed so as to be shifted to one side in the vehicle width direction such that the center of gravity position 51 of the battery 50 is offset from the center line CL.

[0027] The plug-in hybrid vehicle 1 includes a guide rail 11 for sliding the sliding door 4 under the floor panel 100. The guide rail 11 is disposed so as to overlap a part of the battery 50 in the vehicle front-rear direction. The guide rail 11 includes a curved portion 13 that is curved so as to be located closer to the inside in the vehicle width direction toward the front of the vehicle. When closing the sliding door 4, the sliding door 4 is drawn inward in the vehicle width direction along the curved portion 13 of the guide rail 11.

[0028] The plug-in hybrid vehicle 1 has an exhaust pipe 54 disposed under the floor panel 100 for guiding the exhaust from the engine 21 to the rear of the vehicle. The exhaust pipe 54 connects the engine 21 and the muffler 53. The exhaust pipe 54 is disposed closer to the right side of the vehicle and is disposed in the region RA on the right side of the vehicle. That is, the exhaust pipe 54 is disposed closer to the side opposite to the side where the battery 50 is shifted in the vehicle width direction. Further, the exhaust pipe 54 is disposed passing between the battery 50 and the guide rail 11. In addition, the exhaust pipe 54 is bent outward in the vehicle width direction along the curved portion 13 of the guide rail 11.

[0029] The fuel tank 52 is disposed behind the vehicle of the battery 50. The fuel tank 52 is connected to the fuel filler port 17 via a fuel supply pipe 62. A fuel vapor recovery device 55 is disposed behind the vehicle of the rear-wheel drive motor generator MGR and on the side in the vehicle width direction of the muffler 53. The fuel vapor recovery device 55 is a canister that adsorbs fuel vapor gas generated inside the fuel tank 52.

[0030] <Regarding the drive system of the plug-in hybrid vehicle 1> FIG. 8 schematically shows the configuration of the drive system and the electrical system in the plug-in hybrid vehicle 1 of the embodiment.

[0031] As shown in FIG. 8, the plug-in hybrid vehicle 1 includes an in-vehicle unit 25 in the engine compartment 20. Inside the in-vehicle unit 25, a first motor generator MG1, a second motor generator MG2, a power control unit 22, a power split mechanism 23, and a speed reduction mechanism 24 are disposed. As shown in FIG. 8, the second motor generator MG2 is connected to the battery 50 via the power control unit 22. The second motor generator MG2 is connected to the front wheels 14 via the speed reduction mechanism 24. The rotational power of the second motor generator MG2 is transmitted to the front wheels 14 via the speed reduction mechanism 24 which is a power transmission mechanism. That is, the second motor generator MG2 functions as a drive motor.

[0032] Further, the engine 21 is connected to the front wheels 14 via the power split mechanism 23 and the speed reduction mechanism 24. The power split mechanism 23 is a power transmission mechanism similar to the speed reduction mechanism 24. That is, the rotational power of the engine 21 is transmitted to the front wheels 14 via the power transmission mechanism. Note that the first motor generator MG1 is also connected to the power split mechanism 23. The first motor generator MG1 is, for example, a three-phase AC type motor generator. The power split mechanism 23 is a planetary gear mechanism. The power split mechanism 23 can split the driving force among the engine 21, the first motor generator MG1, and the front wheels 14.

[0033] The first motor generator MG1 generates electricity by receiving the driving force from the engine 21 or the driving force from the front wheels 14. Further, when starting the engine 21, the first motor generator MG1 also serves as a starter for driving the crankshaft, which is the output shaft of the engine 21. At that time, the first motor generator MG1 functions as an electric motor that generates a driving force in response to the supply of electric power from the battery 50. That is, the first motor generator MG1 functions as a driving motor.

[0034] The first motor generator MG1 and the second motor generator MG2 are connected to the battery 50 via the power control unit 22. The AC power generated by the first motor generator MG1 is converted into DC power by the power control unit 22. Then, the DC power converted by the power control unit 22 is charged to the battery 50. That is, the power control unit 22 functions as an inverter.

[0035] Also, the DC power of the battery 50 is supplied to the power control unit 22. The supplied DC power is converted into AC power by the power control unit 22. The AC power converted by the power control unit 22 is supplied to the second motor generator MG2. When decelerating the plug-in hybrid vehicle 1, electricity is generated by the second motor generator MG2 using the driving force from the front wheels 14. Then, the generated power is charged to the battery 50. That is, the plug-in hybrid vehicle 1 performs regenerative charging. At this time, the second motor generator MG2 functions as a generator. The AC power generated by the second motor generator MG2 is converted into DC power by the power control unit 22. The DC power converted by the power control unit 22 is charged to the battery 50.

[0036] The rear-wheel drive motor generator MGR is also connected to the battery 50 via the power control unit 22. The rear-wheel drive motor generator MGR is connected to the rear wheels 15 via a reduction mechanism 56 for the rear wheels. The DC power of the battery 50 is converted into AC power by the power control unit 22 and then supplied to the rear-wheel drive motor generator MGR. The rear-wheel drive motor generator MGR is an electric motor that drives the rear wheels 15 using the power supplied from the battery 50. That is, the rear-wheel drive motor generator MGR functions as a drive motor.

[0037] When decelerating the plug-in hybrid vehicle 1, power generation is performed by the rear-wheel drive motor generator MGR using the driving force from the rear wheels 15. Then, the generated power is charged to the battery 50. At this time, the rear-wheel drive motor generator MGR functions as a generator. The AC power generated by the rear-wheel drive motor generator MGR is converted into DC power by the power control unit 22 and then charged to the battery 50.

[0038] <Regarding the electrical system of the plug-in hybrid vehicle 1> As shown in FIG. 8, the plug-in hybrid vehicle 1 includes an in-vehicle charger 40 and an in-vehicle unit 25 in the engine compartment 20. The plug-in hybrid vehicle 1 includes a DC / DC converter 42 in the power control unit 22 that constitutes the in-vehicle unit 25. Further, the plug-in hybrid vehicle 1 includes a first charging port 18 and a second charging port 19 as charging ports into which a charging plug is inserted from outside the vehicle. The first charging port 18 is a charging port used for normal charging performed using an AC power source such as 100V or 200V. The second charging port 19 is a charging port used for rapid charging performed using a DC high-voltage power source such as 50kW.

[0039] As shown in FIG. 8, the battery 50 is connected to the in-vehicle charger 40 via a wire harness. The in-vehicle charger 40 is connected to the first charging port 18 via a wire harness. The in-vehicle charger 40 charges the battery 50 by converting the AC power input from the AC power source connected to the first charging port 18 into DC power and outputting it. That is, the plug-in hybrid vehicle 1 can use an AC power source as an external power source for charging the battery 50.

[0040] The battery 50 is connected to the second charging port 19 via a wire harness. A DC power source is connected to the second charging port 19. The DC power input from the DC power source connected to the second charging port 19 is supplied to the battery 50. That is, the plug-in hybrid vehicle 1 can use a DC power source as an external power source for charging the battery 50.

[0041] The battery 50 supplies DC power to the DC / DC converter 42 and auxiliary devices. The DC / DC converter 42 is a converter that steps down the voltage of the battery 50 and supplies it to the auxiliary devices.

[0042] The auxiliary devices supplied with power from the DC / DC converter 42 are, for example, the electric power steering 59 disposed in the engine compartment 20 and the electric oil pump 60. The electric power steering 59 is a mechanism that assists the driver's steering operation. The electric oil pump 60 is a mechanism for sucking lubricating oil and using it for lubricating the engine 21. The DC / DC converter 42 also supplies power to the air conditioner 57. The air conditioner 57 is a device that conditions the air in the passenger compartment 16 with the power supplied from the DC / DC converter 42.

[0043] The auxiliary devices supplied with DC power from the battery 50 are, for example, the water heater 58. The water heater 58 is a device that heats water to hot water with the power supplied from the battery 50 in order to be a heat source for the air conditioner 57.

[0044] <Operation of this Embodiment> According to the above configuration, compared with a vehicle in which the drive motor, the power control unit 22, the power transmission mechanism, the power control unit 22, and the DC / DC converter 42 are separately arranged, the wire harness used for connecting these devices becomes unnecessary. The size of the unit is smaller than when these devices are separate devices. Therefore, these devices including the in-vehicle charger 40 can be integrated in the engine compartment 20. For this reason, the above plug-in hybrid vehicle 1 can reduce the number of devices mounted under the floor panel 100. Thereby, even if the above plug-in hybrid vehicle 1 mounts a large battery 50 under the floor panel 100, it can secure a flat floor without raising the position of the floor panel 100.

[0045] <Effects of the present embodiment> (1) The above plug-in hybrid vehicle 1 can mount a large battery 50 while realizing a low and flat floor and securing a wide cabin space.

[0046] (2) According to the above configuration, even when a charging plug is inserted into the first charging port 18, the operation of the sliding door 4 is not inhibited. That is, the above plug-in hybrid vehicle 1 can freely operate the sliding door 4 even during charging.

[0047] (3) In the above plug-in hybrid vehicle 1, the fuel filler port 17 is arranged on the side surface of the vehicle and behind the sliding door 4. According to the above configuration, the first charging port 18 and the fuel filler port 17 of the plug-in hybrid vehicle 1 are arranged at different positions on the vehicle. Thereby, the user of the plug-in hybrid vehicle 1 can charge and refuel without confusing the first charging port 18 and the fuel filler port 17.

[0048] (4) The fuel filler port 17 of the above-described plug-in hybrid vehicle 1 is disposed behind the sliding door 4 on the vehicle side where the first charging port 18 is provided, further rearward of the vehicle. According to the above configuration, the first charging port 18 and the fuel filler port 17 are provided on the same side surface of the plug-in hybrid vehicle 1. Therefore, the user of the plug-in hybrid vehicle 1 can easily remember the positions of the first charging port 18 and the fuel filler port 17. For this reason, the plug-in hybrid vehicle 1 can reduce the error in the vehicle orientation when entering the vehicle into the charging stand and the fueling stand.

[0049] (5) The above-described plug-in hybrid vehicle 1 is provided with a second charging port 19. A DC power source can be connected to the second charging port 19. By providing the second charging port 19, the plug-in hybrid vehicle 1 can charge the battery 50 with the electric power supplied from the DC power source. According to the above configuration, the plug-in hybrid vehicle 1 can charge the battery 50 with both the DC power source and the AC power source.

[0050] (6) In the above-described plug-in hybrid vehicle 1, the second charging port 19 is disposed on a vehicle side surface different from the vehicle side surface where the first charging port 18 is disposed and in front of the front door 2 of the vehicle. According to the above configuration, the second charging port 19 to which the DC power source can be connected and the first charging port 18 to which the AC power source can be connected are disposed on different side surfaces of the plug-in hybrid vehicle 1. Therefore, the plug-in hybrid vehicle 1 can prevent the user of the plug-in hybrid vehicle 1 from confusing the second charging port 19 capable of supplying the DC power source and the first charging port 18 capable of supplying the AC power source when charging the plug-in hybrid vehicle 1.
