Movable body rescue system and movable body rescue method
Each vehicle includes a detection device configured to detect a situation outside the vehicle. When a server receives from a depleted EV a help signal requesting power supply from another vehicle to the depleted EV, the server selects, from among the other vehicles, a rescue EV to supply electric power to the depleted EV. The rescue EV moves to the depleted EV, determines a stopping position of the rescue EV from a situation around the depleted EV detected by the detection device, and performs power supply to the depleted EV at the stopping position.
1. A movable body rescue system comprising:
a first movable body equipped with a first power storage device storing electric power for traveling;
a plurality of second movable bodies each equipped with a second power storage device storing electric power for traveling; and
a server configured to communicate with the first movable body and the plurality of second movable bodies, wherein
the first movable body is configured such that the first power storage device can be charged by receiving electric power from any one of the plurality of second movable bodies,
each of the plurality of second movable bodies is configured to supply electric power stored in the second power storage device to the first movable body,
each of the plurality of second movable bodies includes a detection device configured to detect a situation outside the second movable body,
when the server receives from the first movable body a help signal requesting power supply from any one of the plurality of second movable bodies to the first movable body, the server is configured to select, from among the plurality of second movable bodies, a power-supplying movable body to supply electric power to the first movable body, and
the power-supplying movable body is configured to move to the first movable body, determine a stopping position of the power-supplying movable body from a situation around the first movable body detected by the detection device, and perform power supply to the first movable body at the stopping position.
2. The movable body rescue system according to claim 1 , wherein
when it is determined, from the situation around the first movable body detected by the detection device, that there is no element behind the first movable body that hinders the power-supplying movable body from stopping, the power-supplying movable body is configured to determine that a space behind the first movable body is the stopping position.
3. The movable body rescue system according to claim 1 , wherein
when it is determined, from the situation around the first movable body detected by the detection device, that a space behind the first movable body is a no-stopping zone, the power-supplying movable body is configured to determine that a space in front of the first movable body is the stopping position.
4. The movable body rescue system according to claim 1 , wherein
each of the plurality of second movable bodies is configured to transmit to the server a signal indicating whether or not the second movable body can supply electric power to the first movable body, and
when the server receives the help signal from the first movable body, the server is configured to select the power-supplying movable body from among second movable bodies each indicating by the signal its ability to supply electric power to the first movable body.
5. The movable body rescue system according to claim 1 , wherein
when the server receives the help signal from the first movable body, the server is configured to select a second movable body closest to the first movable body of the plurality of second movable bodies as the power-supplying movable body.
6. The movable body rescue system according to claim 1 , wherein
when the server receives the help signal from the first movable body, the server is configured to select, from among the plurality of second movable bodies, a second movable body storing a prescribed and required power amount in the second power storage device as the power-supplying movable body, and
the required power amount is calculated from a stored power amount of the second power storage device, and a power amount that allows travel from a location of power supply to the first movable body to power supply equipment capable of charging the second power storage device.
7. A movable body rescue method used in a system including a first movable body, a plurality of second movable bodies, and a server configured to communicate with the first movable body and the plurality of second movable bodies, wherein
the first movable body is equipped with a first power storage device storing electric power for traveling, and is configured such that the first power storage device can be charged by receiving electric power from any one of the plurality of second movable bodies,
each of the plurality of second movable bodies is equipped with a second power storage device storing electric power for traveling, and is configured to supply electric power stored in the second power storage device to the first movable body,
each of the plurality of second movable bodies includes a detection device configured to detect a situation outside the second movable body, and
the rescue method comprises
when the server receives from the first movable body a help signal requesting power supply from any one of the plurality of second movable bodies to the first movable body, selecting, from among the plurality of second movable bodies, a power-supplying movable body to supply electric power to the first movable body,
moving the power-supplying movable body to the first movable body,
detecting a situation around the first movable body by the detection device;
determining a stopping position of the power-supplying movable body from the situation around the first movable body detected by the detection device; and
supplying electric power from the power-supplying movable body stopped at the stopping position to the first movable body.
