This application is based on and claims the benefit of priority from Japanese Patent Application No. 2021-052867, filed on 26 Mar. 2021, the content of which is incorporated herein by reference.
The present invention relates to a system for sharing driving force.
In recent years, a car-sharing system allowing a plurality of users to use a vehicle in a shared manner is becoming popular. The car-sharing system means a system in which a user becomes a member of a car-sharing operator without possessing a vehicle, to use vehicles possessed by the operator when necessary. In the car-sharing system, since a vehicle is shared by a plurality of users, use at a low cost and convenient use are enabled, possibly increasing demand for use of vehicles.
Patent Document 1 discloses employing a pricing system in which a first rate lower than a standard rate is applied as a usage fee when an SOC (State of Charge) at the time of renting is within a recommended range and the SOC at the time of returning is also within the recommended range, to promote suppression of deterioration of a secondary battery, provided that the “recommended range” refers to a range of a power storage amount (e.g., 30% to 70%) in which a power storage device can be used while suppressing deterioration of the secondary battery included therein.
However, most of the conventional car-sharing systems are targeted at passenger vehicles. In regard to a tow truck, which tows an inhabitation vehicle for camping not provided with driving force and requires driving force of at least a certain value for towing, the “driving force no less than a certain value” varies by user and a system has not been proposed for sharing such a tow truck. In addition, a system has not been proposed either for arranging an additional tow truck in a case in which a user who has departed with a single tow truck, which was considered to be sufficient, encounters an unexpected mountain road with a steep slope.
An objective of the present invention is to provide a system enabling an appropriate movable body to be rented so that a user can achieve a necessary operation according to a purpose of the user.
The present inventors have found that selection of a movable body suitable for a purpose of a user is enabled by: obtaining purpose information from a user terminal; calculating a necessary output on the basis of the purpose information; and performing matching between the necessary output and output information of a rentable movable body, leading to completion of the present invention.
(1) In order to achieve the aforementioned objective, the present invention provides a driving force sharing system provided with a server that configures a movable body to be rented to a user, in which the server: obtains output information of a rentable movable body; obtains purpose information from a user terminal; calculates a necessary output on the basis of the purpose information; and selects the movable body to be rented on the basis of the necessary output.
The driving force sharing system of (1) enables a user to rent an appropriate movable body suitable for the purpose.
(2) In the driving force sharing system according to (1): the purpose information may include route information obtained from a renting location and a destination, and information of a tow object or a load weight; and the necessary output may include driving force calculated on the basis of the purpose information.
The driving force sharing system of (2) enables an appropriate output to be obtained according to the purpose of the user.
(3) In the driving force sharing system according to (1) or (2), the server, on the basis of the necessary output and the output information of a rentable movable body, may configure whether a first movable body capable of delivering an output greater than the necessary output is to be rented, or a plurality of second movable bodies, an output of which is lower than that of the first movable body, is to be rented.
The driving force sharing system of (3) enables efficient rental according to the output of the movable body.
(4) In the driving force sharing system according to (3), the server, in a case in which the output of the second movable body is smaller than an output obtained by adding a predetermined output to the necessary output, may rent the second movable body when an additional arrangement of a movable body is possible on a route, and may rent the first movable body when the additional arrangement of a movable body is not possible on the route.
The driving force sharing system of (4) prevents renting of a movable body with an unnecessarily great output, thus increasing efficiency.
(5) In the driving force sharing system according to (3), the server: may calculate a first fee for renting the first movable body singly and a second fee for renting a plurality of the second movable bodies; and may configure a rental pattern on the basis of the first fee and the second fee.
The driving force sharing system of (5) enables rental to the user based on an appropriate fee.
According to the present invention, a system enabling renting of an appropriate movable body for realizing a necessary operation according to a purpose of a user can be provided.

In addition, the various sensors 360 may include a torque sensor for measuring driving force generated in the rental movable body 300. Furthermore, a sensor may also be provided for measuring an amount of fuel (hereinafter referred to as “fuel amount”) of the rental movable body 300 or electric power amount of the rental movable body 300.
Step S202: The user uses the user terminal 21 to register user information to the server 22. Step S203: The rental movable body 23 registers a rentable period and the current SOC to the server 22.
Step S204: The user uses the user terminal 21 to register: a location where the user wishes to rent the rental movable body 23; a period of renting the rental movable body 23; a purpose (weight to tow, loaded weight); a travel route; and the like. In addition, the AC output and the low-voltage output in the case of using the rental movable body 23 as a power source may be registered. Step S205: The server 22 calculates a necessary output (torque/electric power) on the basis of the purpose (weight to tow, loaded weight) transmitted from the user terminal 21. In addition, the server 22 calculates a necessary energy amount (fuel amount/electric power amount) on the basis of the purpose (weight to tow, loaded weight) transmitted from the user terminal 21, and the travel route.
Step S206: The server 22 performs matching on the basis of information of a rental request from the user terminal 21 and information of the specification registration from the rental movable body 23. The logic of this matching is explained later in detail in the section <Logic of Selection of Rental Movable Body>. Step S207: The server 22 transmits to the matched rental movable body 23 information of: a renting location; a renting period; a purpose (weight to tow, loaded weight); and a travel route.
Step S208: The server 22 transmits to the matched user terminal 21 of the user, information regarding the rental movable body 23 determined to be rented. Step S209: The user rents the rental movable body 23. Step S210: While the user uses the rental movable body 23, the rental movable body 23 periodically transmits the usage status to the server 22. The usage status is exemplified by the output (torque/electric power), the current location, the SOC, the load status or the tow status, and the like.
Step S211: When the user finishes using the rental movable body 23, the user returns the rental movable body 23. Step S212: The server 22 calculates the usage fee. Step S213: The server 22 charges the user the usage fee. The usage fee consists of a using charge for using the driving force sharing system, and an actual cost portion corresponding to a cost of the fuel or electricity consumed. Step S214: The user pays the usage fee.
Step S306: The server 22 calculates a necessary output (torque/electric power) and a necessary energy amount (fuel amount/electric power amount). Step S307; The server 22 performs matching. As a result, it turns out that the rental movable body 1 is not sufficient to satisfy the request from the user and it is necessary to rent the rental movable body 2 as well. Step S308: The server 22 requests rental to the rental movable body 1. Step S309: The server 22 transmits renting information to the user terminal 21. Step S310: The server 22 requests rental to the rental movable body 2.
Step S311: The rental movable body 1 is rented. Step S312: The rental movable body 2 is rented. Step S313: Identical to Steps S210 and later in
Suppose that the process of Steps S201 to S209 in
Step S404: In such a case, the server 22 recalculates the necessary driving force. Step S405: The server 22 selects the rental movable body 2 to be additionally rented. Step S406: The server 22 recommends to the user the rental movable body 2 to be additionally rented. Step S407: The user accepts additionally renting the rental movable body 2 and transmits that effect to the server 22.
Step S408: The server 22 requests an additional rental of the rental movable body 2. Step S409: The user rents the rental movable body 2. Since Steps S410 and later are similar to Steps S210 and later in

In addition, the steps of checking the fuel amount/electric power amount may be omitted. In other words, Steps S701 to S708 may be omitted. Furthermore, both of Steps S601 to S608 and Steps S701 to S708 may be omitted.
In S214 in the embodiment, the owner of the rental movable body 300 is the owner of the server, and the user pays the usage fee to the owner of the server; however, when the owner of the rental movable body is someone different from the owner of the server, such as another user, it may also be configured that the usage fee from the user, who is a renter, and an incentive are paid to the owner of the rental movable body via the server.
In addition to an inhabitation vehicle for camping not provided with driving force, the vehicle to be towed is assumed to be, but not limited to, a passenger vehicle of a driver who had departed by car with no intention of consuming alcohol but consumed alcohol on the way, a waste collection vehicle, an agricultural vehicle, and the like.
The usage fee may also be a sum of a commission charge of the system and a using charge set to each rental movable body. The using charge set to each rental movable body may be proportional to a value obtained by multiplying the driving force with a usage period. When the plurality of rental movable bodies is rented, the driving force is a sum of driving forces of the rental movable bodies. In addition, in a case in which, before returning the rental movable body after use, the user refills the movable body past the fuel level or the charged level prior to the rental, an amount corresponding to a difference in level may be deducted from the using charge.
The present invention is not limited to the embodiment, and all modifications and improvements within a scope in which the objective of the present invention can be attained are encompassed in the present invention.
