FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] A mobility system according to one embodiment of the present invention comprises a cabin 100 on which electrical equipment 108-110 belonging to a first group and electrical equipment 104-107 belonging to a second group are mounted, and an aerial mobility module 300 configured to move through the air and equipped with an aerial mobility battery 301 that supplies power to the driving source for the movement, and which can be removably connected to the cabin 100. When the cabin 100 and the aerial mobility module 300 are connected, the aerial mobility battery 301 supplies power to the electrical equipment 108-110 belonging to the first group, but does not supply power to the electrical equipment 104-107 belonging to the second group. This reduces power consumption when moving through the air and increases the distance that can be traveled through the air. [Example]

[0010] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. FIG. 1 schematically shows a mobile system 1 according to an embodiment. 1, the mobility system 1 includes a cabin 100 in which passengers can board, and a ground mobility module 200 configured for ground travel and an aerial mobility module 300 configured for air travel can be selectively and detachably coupled to the cabin 100. In this way, the mobility system 1 is configured to be mobile both on the ground and in the air by coupling the cabin 100 and the ground mobility module 200 when traveling on the ground, and coupling the cabin 100 and the aerial mobility module 300 when traveling in the air.

[0011] FIG. 2 shows a schematic configuration of the cabin 100. The cabin 100 is equipped with a connector 101 and various electrical components 104-110. The connector 101 connects to a connector 204 (see FIG. 3) of the ground movement module 200, which will be described later, of the ground movement module 200 when the ground movement module 200 is coupled to the cabin 100, and connects to a connector 304 (see FIG. 4) of the air movement module 300 when the air movement module 300 is coupled to the cabin 100. The connector 101 has a first pin 101a and a second pin 101b. Note that the connector 101 also has other pins, but only the first pin 101a and the second pin 101b are illustrated here.

[0012] Electrical components 108-110 belonging to a first group are connected to the first pin 101a via a connection wire 103. The first group includes electrical components 108-110 that are used (or, alternatively, "required") for both ground movement and air movement. In this embodiment, the first group includes a navigation audio 108, a docking module determination device 109, and other electrical components 110. The docking module determination device 109 determines whether a ground movement module 200 or an air movement module 300 has been connected to the cabin 100.

[0013] The second pin 101b is connected to electrical components 104 to 107 belonging to a second group via a connection wire 102. The second group is connected to electrical components 104 to 107 that are used for ground movement but not used (or may be said to be "not required") for air movement. In this embodiment, the second group includes an ETC 104, a drive recorder (dashcam) 105, advanced safety devices 106 such as cameras, and other electrical components 107.

[0014] FIG. 3 shows a schematic configuration of the ground movement module 200. The ground movement module 200 is equipped with a ground movement battery 201, a ground movement motor 202 which is a drive source for ground movement, a converter 203, and a connector 204. The ground movement battery 201 supplies power to the ground movement motor 202. The ground movement battery 201 is connected to a connector 204 via a converter 203. The converter 203 converts the power supplied from the ground movement battery 201 into power that can be used by the electrical components 104 to 110 mounted on the cabin 100. The connector 204 includes a first connection portion 204a to which the first pin 101a of the connector 101 is connected and a second connection portion 204b to which the second pin 101b of the connector 101 is connected when the ground movement module 200 is coupled to the cabin 100, and is configured so that power is supplied from the ground movement battery 201 to both the first connection portion 204a and the second connection portion 204b via a connection line 205.

[0015] FIG. 4 shows a schematic configuration of the airborne movement module 300. The airborne movement module 300 is equipped with an airborne movement battery 301, an airborne movement motor 302 which is a drive source for airborne movement, a converter 303, and a connector 304. Aerial movement battery 301 supplies power to aerial movement motor 302. Aerial movement battery 301 is connected to connector 304 via converter 303. Converter 303 converts the power supplied from aerial movement battery 301 into power usable by electrical components 108-110 mounted on cabin 100. Connector 304 includes first connection portion 304a to which first pin 101a of connector 101 is connected when aerial movement module 300 is coupled to cabin 100, and second connection portion 304b to which second pin 101b of connector 101 is connected. The connection is configured such that power is supplied from aerial movement battery 301 to first connection portion 304a via connection line 305, but power is not supplied from aerial movement battery 301 to second connection portion 304b.

[0016] In the mobility system 1 configured as described above, when the cabin 100 and the ground mobility module 200 are connected, the ground mobility battery 201 supplies power to the electrical components belonging to the first group (navigation audio 108, connection module determination device 109, other electrical components 110) and the electrical components belonging to the second group (ETC 104, drive recorder (dash cam) 105, advanced safety devices 106 such as cameras, and other electrical components 107).

[0017] On the other hand, when the cabin 100 and the airborne movement module 300 are connected, the airborne movement battery 301 supplies power to the electrical components belonging to the first group (navigation audio 108, connection destination module determination device 109, and other electrical components 110), but does not supply power to the electrical components belonging to the second group (ETC 104, drive recorder (dash rec) 105, advanced safety device 106, and other electrical components 107). The electrical components 104 to 108 belonging to the second group are used when moving on the ground, but are not used when moving in the air, and do not need to be on standby, consuming standby power.

[0018] As described above, when the cabin 100 and the aerial movement module 300 are coupled, power supply from the aerial movement battery 301 to the electrical components belonging to the second group is prevented, thereby eliminating standby power consumption. This reduces power consumption when moving through the air and uses that power for moving through the air, thereby extending the distance that can be moved through the air.

[0019] Furthermore, when the coupled module determination device 109 determines that the aerial movement module 300 has been coupled to the cabin 100, i.e., when the aerial movement battery 301 is the power supply source, some of the functions of the electrical components belonging to the first group may be degraded. The coupled module determination device 109 may determine whether power is being supplied from the ground movement battery 201 or the aerial movement battery 301, for example, based on whether communication with electrical components belonging to the second group is possible, in other words, whether the ground movement module 200 or the aerial movement module 300 has been coupled to the cabin 100. In this embodiment, when the coupled module determination device 109 determines that the aerial movement module 300 has been coupled to the cabin 100, only the navigation function of the navigation audio 108 is made available, and the audio function that produces sound is turned off. Regarding the Navigation Audio 108, the navigation function is recognized as effective for confirming one's position in the air, but the audio function is likely to be obscured by the power noise generated by moving through the air, in which case it is assumed that its effectiveness will be small and it will not be needed.

[0020] The first and second groups may be appropriately divided depending on whether or not it is desired to retain the function during airborne movement, for example. Furthermore, when the cabin 100 and the aerial movement module 300 are coupled, power is not supplied to the electrical components belonging to the second group. However, if any of the electrical components belonging to the second group communicates with the controller mounted on the cabin 100, the communication function will also stop when power supply is stopped, and there is a possibility that the controller with which the communication is made to mistakenly detect the communication interruption as a malfunction. Therefore, for example, when the controller recognizes that the aerial movement module 300 has been coupled to the cabin 100, it is possible to take measures to stop the function for detecting malfunctions due to communication interruption.

[0021] The following describes the modified example with reference to FIGS. 5 to 7 are schematic diagrams for explaining the connection configuration between connectors 101, 113, and 114 of cabin 100, connector 204 of ground movement module 200, and connector 304 of airborne movement module 300. Each diagram (a) shows the state in which cabin 100 and airborne movement module 300 are connected, and each diagram (b) shows the state in which cabin 100 and ground movement module 200 are connected. In FIGS. 5 to 7, electrical components belonging to the first group are represented as electrical components 111, and electrical components belonging to the second group are represented as electrical components 112.

[0022] FIG. 5 shows an example in which a connector 101 that is shared by both the ground movement module and the air movement module is provided in the cabin 100, as in the above-described embodiment. If a shared connector 101 is provided, the number of connectors can be reduced, thereby simplifying the wiring in the cabin 100. On the other hand, if the coupling position of the ground movement module 200 to the cabin 100 differs from the coupling position of the airborne movement module 300, connecting the connector 204 of the ground movement module 200 and the connector 304 of the airborne movement module 300 to the shared connector 101 requires time and effort, such as having to rotate and attach the illustrated harnesses 206, 306.

[0023] FIG. 6 shows an example in which a cabin 100 is provided with a connector 113 for a ground movement module and a connector 114 for an air movement module. Connector 113 has pins 113a that connect to connector 204 on the ground movement module 200 side. Pins 113a connect to electrical components 111 belonging to the first group and electrical components 112 belonging to the second group. On the other hand, connector 114 has pins 114a that connect to connector 304 on the air movement module 300 side. Pins 114a connect to electrical components 111 belonging to the first group, but are not connected to electrical components 112 belonging to the second group. In this case, as in the embodiment, when the cabin 100 and the ground movement module 200 are coupled (FIG. 6(b)), the ground movement battery 201 supplies power to the electrical components 111 belonging to the first group and the electrical components 112 belonging to the second group. On the other hand, when the cabin 100 and the air movement module 300 are coupled (FIG. 6(a)), the air movement battery 301 supplies power to the electrical components 111 belonging to the first group, but does not supply power to the electrical components 112 belonging to the second group. 6, the positions of connectors 113, 114 can be freely determined depending on the coupling position of ground movement module 200 and that of airborne movement module 300 relative to cabin 100, eliminating the need to rotate and attach a harness as in the case of providing shared connector 101 as described in Fig. 5. Furthermore, by separating the power supply line from ground movement module 200 and the power supply line from airborne movement module 300, the design is simplified.

[0024] 7 shows an example in which a connector 113 for a ground movement module and a connector 114 for an air movement module are provided in a cabin 100, similar to FIG. Connector 113 has pins 113b and 113c that connect to connector 204 on the ground movement module 200 side. Pin 113b connects to electrical component 112 belonging to the second group, and pin 113c connects to electrical component 111 belonging to the first group. On the other hand, connector 114 has pin 114a that connects to connector 304 on the aerial movement module 300 side. Pin 114a is connected to electrical component 111 belonging to the first group, and is not connected to electrical component 112 belonging to the second group. In this case, pin 113c, pin 114a, and electrical component 111 belonging to the first group are configured to be connected by a common power supply line. In this case, as in the embodiment, when the cabin 100 and the ground movement module 200 are coupled (FIG. 7(b)), the ground movement battery 201 supplies power to the electrical components 111 belonging to the first group and the electrical components 112 belonging to the second group. On the other hand, when the cabin 100 and the air movement module 300 are coupled (FIG. 7(a)), the air movement battery 301 supplies power to the electrical components 111 belonging to the first group, but does not supply power to the electrical components 112 belonging to the second group. 7, the positions of connectors 113, 114 can be freely determined according to the coupling position of ground moving module 200 and the coupling position of air moving module 300 to cabin 100, respectively, eliminating the need to rotate and attach a harness as in the case of providing shared connector 101 as described in Fig. 5. Also, while two power supply lines are connected to electrical component 111 in the example of Fig. 6, in the example of Fig. 7, it is sufficient to connect one power supply line to electrical component 111, allowing the power supply wiring to be unified.

The technical scope of the present invention is not limited to each embodiment.
