The traveling actuator 49 performs braking or steering of the wheels 18.

[Control in Embodiment]
Next, FIG. 4 is a flowchart showing the process which the indoor vehicle side control part 40 starts at the time of power activation. In this process, control of each part on the main body 20 side is executed in cooperation with the main body control unit 30.

  As shown in FIG. 4, in this process, first, in S1 (S represents a step: the same applies hereinafter), it is determined whether or not the connectors 19 and 29 are connected to each other. This determination can be performed based on, for example, whether or not control signals can be transmitted to and received from the main body side control unit 30.

  If the connectors 19 and 29 are not connected (N in S1), the process proceeds to S2, and control for switching the drive destination switching clutch 47 to the wheel 18 side is executed. Note that this step is directly passed if the drive destination switching clutch 47 has already been switched to the wheel 18 side at the time of shifting to this step. In subsequent S3, the wheel for controlling the rotation, braking, and steering state of the wheel 18 via the traveling motor 17 and the traveling actuator 49 in accordance with the operation state of each traveling operation unit detected by the traveling operation unit sensor 45. Control is executed, and the process proceeds to S1 described above. For this reason, when the connectors 19 and 29 are not connected (N in S1), for example, when the indoor vehicle 10 is moving indoors away from the main body 20, the operating state of each traveling operation unit In response to the control, the wheel 18 is controlled (S3).

  On the other hand, if the rear end portion of indoor vehicle 10 is fitted inside support portion 29A and connectors 19 and 29 are connected to each other (Y in S1), the process proceeds to S5 and the drive destination is switched. Control for switching the clutch 47 to the gear 17A side is executed. Note that this step is directly passed if the drive destination switching clutch 47 has already been switched to the gear 17A side at the time of shifting to this step. In subsequent S <b> 6, control for closing the ramp way 27 is executed via the ramp way driving device 37. This step is directly passed if the ramp way 27 has already been closed at the time of shifting to this step.

  In subsequent S7, the operation state of each traveling operation unit is detected via the traveling operation unit sensor 45, and it is determined whether or not any operation has been performed. If there is no operation (N in S7), the process waits in S7 as it is, and if there is an operation (Y in S7), the process proceeds to S8 to instruct that the operation goes up to the floor F. It is determined whether or not the operation. That is, there is an operation unit such as a switch that can be instructed to go up to the floor F by the indoor vehicle 10 at the handle 11 or in the vicinity thereof. It is determined whether or not. If the operation detected in S7 does not instruct to go up to the floor F (N in S8), the process proceeds to S9. In S9, wheel control for controlling the rotation, braking, and steering states of the wheels 28 via the traveling motor 17 and the traveling actuator 33 according to the operation state of each traveling operation unit detected by the traveling operation unit sensor 45. Is executed, and the process proceeds to S1 described above. For this reason, for example, when the indoor vehicle 10 is fixed to the main body 20 and the connectors 19 and 29 are connected (Y in S1), until the floor F is instructed (N in S8). Then, the control for the wheel 28 is executed according to the operation state of each traveling operation section (S9).

  Next, when the user stops electric vehicle 1 forward in front of floor F and instructs to move up to floor F (Y in S8), the process proceeds to S11. In S11, the vehicle height is adjusted so that the upper end of the hinge 27A coincides with the upper end of the floor F by controlling the vehicle height adjusting device 35 based on the image taken by the front camera 31. In subsequent S12, control is performed to open the ramp way 27 via the ramp way driving device 37, and the process proceeds to S2 described above. Then, in response to depression of the accelerator pedal 12, the indoor vehicle 10 can travel on the floor F across the ramp way 27 (S2, S3). Thus, when the indoor vehicle 10 is separated from the main body 20, the connectors 19 and 29 are also separated (N in S1), so that the processes of S2 and 3 are repeated as described above.

[Effects of the embodiment and modifications thereof]
Thus, in the electric vehicle 1 of the present embodiment, the rear seat 5, the indoor vehicle 10, the handle 11, the projector 14, the air conditioner 15, the car stereo 16, the headlight 21, the refrigerator 23, or the drink holder 25 (all of which As described above, the batteries 5B to 25B can be charged while being used indoors as described above. For this reason, the batteries 5B to 25B for traveling the electric vehicle 1 can be brought into the room and charged easily, and it is possible to satisfactorily prevent the living space from being compressed during the charging. Further, the battery 28 </ b> B can be charged while the wheel 28 is exchanged from winter to summer and held in the wheel stand 50. Further, in the present embodiment, the batteries 5B to 28B provided in the respective members including the solar cell 24 supply power to the traveling motor 17 while allowing power to be interchanged. Therefore, even when the capacities of the individual batteries 5B to 28B are small, sufficient electric power can be supplied to the traveling motor 17 and the electric vehicle 1 can travel well.

  In addition, in the said embodiment, when it is instruct | indicated that it goes up to the floor F, the remaining amount of each battery 5B-25B is detected, and the battery (any one of 5B-25B) with the least remaining amount is notified. May be. In that case, the user can perform charging more efficiently by bringing the electrical component configured integrally with the battery (any one of 5B to 25B) with the least remaining amount into the room and charging it. The notification is provided when a seating sensor for detecting that a driver (user) is seated in the driver's seat 3 is provided, and when the seating sensor detects that the driver has stood.
