Description

[Technical Field]

[0001] The present invention relates to a vehicle management system and a vehicle management method for managing vehicles (hereinafter referred to as "shared cars") shared through a subscription-based car sharing service, as well as a program for operating a computer as a server provided by the vehicle management system. [Background technology]

[0002] Car sharing has become popular in recent years. For example, since 2015, the number of shared cars and vehicle stations has been steadily increasing, and the number of car sharing users has increased significantly, especially in urban areas. Car sharing allows you to use a car only when you need it without having to own it, which has the advantage of reducing the burden of maintenance costs such as parking fees, car insurance, vehicle inspection fees, and automobile tax. For this reason, car sharing is expected to become even more popular in the future.

[0003] Therefore, there is a need for a highly convenient system for managing shared cars. For example, Patent Document 1 describes a vehicle management system aimed at improving vehicle utilization rates. This vehicle management system includes: a storage means for storing user information including an evaluation of the user who uses the vehicle for each user; a first evaluation means for determining whether the user's use of the vehicle has caused a cause of loss of opportunity to use the vehicle and evaluating the user who used the vehicle based on the result of the determination; a second evaluation means for having a subsequent user who uses the vehicle evaluate the usage manner of the vehicle by a preceding user who used the vehicle immediately before and evaluating the preceding user based on the evaluation by the subsequent user; an evaluation update means for determining an evaluation of each user who uses the vehicle for each user based on the evaluation results by the first evaluation means and the second evaluation means and storing the determined evaluation of each user in the storage means; and a usage fee setting means for setting a usage fee for using the vehicle for each user based on the evaluation of each user stored in the storage means.

[0004] Furthermore, Patent Document 2 describes an information processing system aimed at efficiently managing comprehensive maintenance and inspection information for shared vehicles. This information processing system has a server device and a control unit, and the control unit acquires first status information, which is information about the vehicle's status at the time the current user begins using the vehicle, and compares the first status information with second status information, which is information about the vehicle's status acquired when the previous user used the vehicle. The control unit also evaluates the previous user based on the comparison result between the second status information and the first status information, and notifies the previous user of the evaluation result.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-054538 [Patent Document 2] Japanese Patent Application Laid-Open No. 2023-113449 Summary of the Invention [Problem to be solved by the invention]

[0006] In subscription-based car sharing services, a single shared car at a vehicle station is generally shared by 5 to 15 users belonging to a single community. Whether or not users clean the interior of the shared car and refuel it after using it is left to the discretion of each user, and it is difficult to force each user to clean or refuel. Therefore, the lack of thoroughness of some users in cleaning and refueling can be one factor that leads to lower satisfaction among other users in the same community. In response to these issues, the inventions described in References 1 and 2 aim to improve vehicle utilization rates and efficiently manage comprehensive vehicle maintenance and inspection information, and therefore neither of them can solve the above issues.

[0007] Therefore, the present invention aims to provide a vehicle management system, vehicle management method, and program that can improve satisfaction throughout the community by making users aware of things like cleaning the inside of a shared car when they finish using it and refueling the car for the next user. [Means for solving the problem]

[0008] The vehicle management system of the present invention includes a server that communicates with user terminals and manages vehicles (shared cars) shared through a subscription-based car sharing service. The server also includes a storage unit that stores information about users, evaluation results from users of other users, and information about a community consisting of multiple users sharing a single shared car. The server also includes an evaluation unit that sends evaluation questions to the user's terminal regarding the usage status of a user who used the shared car immediately before the user, receives responses from the terminal, and accumulates and stores the responses in the storage unit. A calculation unit that references the information stored in the storage unit and calculates the contribution level of each user to the community based on the number of times the user answered the evaluation questions and the user's evaluation score. The calculation unit visualizes the contribution level calculated by the calculation unit as the distance between a reference icon and the user's icon, and displays a list of the visualized contribution levels for all users belonging to the community on the user's terminal.

[0009] Furthermore, it is desirable that the calculation means calculates an evaluation score indicating the good or bad state of the entire community based on each user's contribution to the shared car, and that the display means display the evaluation score on the user's terminal.

[0010] Here, it is desirable that the user icon is assigned by the server and does not allow the individual user to be identified.

[0011] It is desirable that one community be made up of 5 to 15 users.

[0012] On the other hand, the vehicle management method of the present invention uses a vehicle management system having a storage means, an evaluation means, a calculation means, and a display means, and equipped with a server that communicates with user terminals, and that manages vehicles (shared cars) shared in a subscription-based car sharing service, and includes the steps of storing information about users, the results of evaluations made by one user to other users, and information about a community made up of multiple users that shares one shared car in the storage means; the evaluation means sending evaluation questions to the user's terminal regarding the usage status of the user who used the shared car immediately before the user, accepting answers from the terminal, and accumulating and storing the answers in the storage means; the calculation means referring to the information stored in the storage means and calculating the contribution level to the community for each user based on the number of times the user answered the evaluation questions and the user's evaluation points; and the display means visualizing the contribution level calculated by the calculation means as the distance between a reference icon and the user's icon, and displaying a list of the visualized contribution levels for all users belonging to the community on the user's terminal.

[0013] On the other hand, the program of the present invention is a program for causing a computer to operate as the server provided in the vehicle management system. [Effects of the Invention]

[0014] According to the vehicle management system of the present invention, the display means visualizes the contribution level calculated by the calculation means as the distance between the reference icon and the user's icon, and displays a list of the visualized contribution levels for all users belonging to the community on the user's terminal, allowing each user to see at a glance how much they contribute to the community. As a result, if a user U's contribution level is lower than that of other users, this can motivate the user U to make an effort to clean the interior of the car more, refuel, and rate other users more carefully. This can encourage users to have the car cleaned thoroughly when they finish using it, or to have the car refueled for the next user, thereby improving satisfaction throughout the community.

[0015] Furthermore, the vehicle management method and program of the present invention can achieve the same effects as the vehicle management system of the present invention. [Brief explanation of the drawings]

[0017] The following describes in detail an embodiment of the present invention. However, the description of the constituent elements described below is an example (representative example) of an embodiment of the present invention, and the present invention is not limited to the following content unless the gist of the present invention is changed.

[0018] [Vehicle management system] First, with reference to FIG. 1, the configuration of a vehicle management system 1 according to this embodiment will be described.

[0019] The vehicle management system 1 includes a server (vehicle management device) 10 that is connected to a network communication network N by wire or wirelessly. A terminal 20 owned by a user U of the vehicle management system 1 is also connected to the network communication network N. The server 10 communicates with the terminal 20 via the network communication network N using communication means 11, which will be described later.

[0020] The terminal 20 is, for example, a smartphone, tablet, or personal computer owned by the user U. In other words, the terminal 20 is a device that has a web browser function and can connect to the Internet (network communication network N).

[0021] The server 10 includes a communication means 11 , a storage means 12 , an evaluation means 13 , a calculation means 14 , a display means 15 , a reservation management means 16 , and a control means 17 .

[0022] The communication means 11 is a function for communicating with the terminal 20, the shared car C, external devices and systems, etc. via the network communication network N.

[0023] The storage means 12 has a function of storing various information. In this embodiment, a database is constructed as the storage means 12, and information about the user U, information about the evaluation results, information about the community, and the like are stored in the database.

[0024] In this explanation, a community refers to a group of multiple users U who share a single shared car at a single vehicle station. In reality, there are many communities, but in this explanation, we will use one community as an example.

[0025] To explain the various types of information stored in the storage means 12 in more detail, information about user U includes, for example, the name, age, sex, address, and telephone number of user U. Information about evaluation results includes the number of times a user U has rated other users U, and evaluations of a user U (number of times rated, average rating, breakdown of evaluation content, etc.) (see, for example, the contribution (individual) display area 43 in FIG. 5(A)). Information about a community includes information about multiple users U who belong to a community, and evaluation scores that indicate the overall state of the community (hereinafter sometimes referred to as the "satisfaction level" of the community as a whole).

[0026] The evaluation means 13 transmits to the terminal 20 of a certain user U an evaluation question regarding the usage status of the user U who used the shared car C immediately before the user U, and receives a response from the terminal 20. The evaluation means 13 accumulates and stores the responses received from the terminal 20 in the storage means 12.

[0027] The calculation means 14 refers to the information stored in the storage means 12 and calculates, for each user U, the degree of contribution to the community to which the user U belongs. Furthermore, the calculation means 14 calculates the satisfaction level of the entire community based on the degree of contribution of each user U.

[0028] The display means 15 visualizes the degree of contribution calculated by the calculation means 13 as a distance between the reference icon 51 and the icon 52 of the user U, and causes the terminal 20 to display a list of the visualized degrees of contribution for all users U who belong to the community (see FIG. 5). The display means 15 also causes the terminal 20 to display the satisfaction level of the entire community calculated by the calculation means 13.

[0029] The reservation management means 16 has the function of executing a series of procedures required when a user U reserves a shared car C.

[0030] The control means 17 executes various controls necessary for the operation of the server 10. For example, the control means 17 has the function of communicating with the shared car C to unlock or lock the shared car C.

[0031] [Vehicle management method] Next, a vehicle management method according to this embodiment using the vehicle management system 1 will be described with reference to the steps shown in Fig. 2 and Figs. 3 to 7. This description will be based on the flow from when a user U rents a shared car C to when the user returns the car after use.

[0032] First, the user U uses the web browser function of the terminal 20 to make a reservation for the shared car C. Specifically, the user U specifies the desired rental date and time period on a reservation screen (not shown) displayed on the terminal 20 and makes a reservation (step S10). The server 10 receives a summary request from the terminal 20 and returns a reservation response (step S11, see FIG. 3(A)). These exchanges are carried out by the reservation management means 16 and the display means 15 of the server 10. The procedures up to when the user U reserves the shared car C can be carried out using known technology.

[0033] Once the reservation of the shared car C is completed, the user U goes to the station where the shared car C is located at the reserved date and time, unlocks the shared car C, and begins using it (steps S20, S21).

[0034] At this time, when the use of the shared car C begins, the server 10 uses the evaluation means 13 to send to the terminal 20 an evaluation question regarding the usage status of the user U who used the shared car C immediately before the user U (step S30). Then, for example, when the user U gets into the shared car C, the user U answers the question from the terminal 20 (step S31).

[0035] 3(B) is an example of a question screen displayed on the terminal 20. In this embodiment, questions regarding the evaluation of the usage status are posed with two choices (Good / Bad) regarding cleaning and refueling.

[0036] In response to this question, user U selects either Good or Bad (see FIG. 4(B)). If answering Good, user U presses Good button 31 and then presses rating decision button 33 (see FIG. 4(A)). On the other hand, if answering Bad, user U presses Bad button 32 and then presses rating decision button 33 (see FIG. 4(B)).

[0037] Responses from the terminal 20 are accepted by the evaluation means 13 of the server 10 and are accumulated and stored in the storage means 12. For example, if the user U responds with "Good," the number of responses from the user U is incremented, and information such as when, to whom, and what kind of evaluation ("Good" in this embodiment) was given is stored in the storage means 12. In addition, information regarding the user U who received the evaluation (the previous user U), such as when, by whom, and what kind of evaluation ("Good" in this embodiment) was given, is also stored in the storage means 12.

[0038] In this embodiment, if the user U answers "Bad," the user is further asked to provide the reason. For example, in this embodiment, the user U is asked about the reasons for answering "Bad," such as whether there was "insufficient cleaning" and whether "fuel (gasoline) was below 50%" (see FIG. 4(B)).

[0039] More specifically, when the user U presses the Bad button 32, the evaluation means 13 causes the terminal 20 to display a Bad cleaning button 35 and a Bad refueling button 36. In response, the user U presses either or both of the Bad cleaning button 35 and the Bad refueling button 36, and then presses the evaluation decision button 33. The evaluation means 13 receives this information, including the reason for the Bad response, and accumulates and stores it in the storage means 12. For example, if user U responds Bad, the number of responses by user U is incremented, and information such as when, to whom, and what kind of evaluation (Bad in this embodiment) was given is stored in the storage means 12. In addition, information such as when, by whom, and what kind of evaluation (Bad in this embodiment) was given for user U (immediately preceding user U) who was evaluated is also stored in the storage means 12.

[0040] It should be noted that such evaluation (step S31) can be skipped by pressing the skip button 34 (see FIG. 3(B) and FIG. 4).

[0041] In the above manner, the storage means 12 of the server 10 accumulates and stores evaluations of each user U (number of times rated, average score of evaluation, breakdown of evaluation content, etc.), and the calculation means 14 refers to this information stored in the storage means 12 and calculates the degree of contribution to the community for each user U.

[0042] The degree of contribution to shared car C varies depending on the evaluation content (question content), but in this embodiment, the evaluation content is about cleaning and refueling, so the degree of contribution to the community is determined by the degree of contribution, such as "how much user U has contributed to keeping shared car C clean" and "how much user U has contributed to ensuring that the next user can start using shared car C comfortably."

[0043] The calculation method of the degree of contribution by the calculation means 14 can be designed arbitrarily. In the present embodiment, for example, a Good evaluation is given as 1 point, a Bad evaluation is given as 0 point, and so on. ((Number of times rated as Good + number of times rated yourself / 2)) / Number of times used and can be calculated. For example, if a user U uses shared car C 100 times, is rated Good by all subsequent users U, and rates the subsequent user U every time without skipping, then the contribution will be 1 (100 points). On the other hand, if another user U also uses shared car C 100 times, and is rated Good by all subsequent users U, but does not rate the subsequent user U at all (skipped every time), then the contribution will be 0.5 (50 points).

[0044] In the above example, the calculation means 14 calculates the contribution level based on the number of times that user U answered the evaluation questions and the user U's evaluated points, but factors other than the number of answers and the evaluated points may also be used to calculate the contribution level. Also, in the above example, the weighting of the number of answers and the evaluated points is 1:1, but the weighting may be changed. Note that for users U who have used the service less than a predetermined number of times (for example, less than 20 times), the contribution level may not be calculated because the number of samples is small.

[0045] Furthermore, the calculation means 14 calculates the satisfaction level of the entire community based on this contribution level. The calculation method of the calculation means 14 can be designed arbitrarily, but in this embodiment, an example is as follows: Sum of contributions of users U belonging to the community / Number of users U belonging to the community and can be calculated.

[0046] Of course, the method of calculating satisfaction is not limited to the example given above, and the frequency of use of shared car C (shared car C is always used) may be used as a factor in calculating satisfaction, or the weighting of the contribution of user U who uses it frequently may be changed.

[0047] The degree of contribution and the degree of satisfaction calculated by the calculation means 14 are stored in the storage means 12.

[0048] The user U can then refer to his or her own contribution level and the overall satisfaction level of the community to which he or she belongs at any time. Specifically, when the user U transmits a request to acquire the community status, etc. from the terminal 20 to the server 10 (step S40), the server 10 returns a display of the community status, etc. to the terminal 20 via the display means 15 (step S41). Then, the terminal 20 displays the community status, etc. as shown in FIG. 5.

[0049] 5(A) is an example of displaying the community status of a certain community, and first, the satisfaction level of the entire community is displayed in the satisfaction level display area 42. In this embodiment, the satisfaction level is displayed as a score together with a short comment. The contribution level (individual) display area 43 displays the contribution level of an individual user U. In this embodiment, along with a short comment, the number of times the user has rated the user, the number of times other users U have rated the user as Good, and the user's own contribution level are displayed as points.

[0050] Furthermore, the display means 15 refers to the storage means 12, visualizes the degree of contribution as the distance between the reference icon 51 and the icon 52 of the user U, and displays a list of the visualized degrees of contribution for all users U who belong to the community. In this embodiment, the visualized degrees of contribution are displayed in a list in the contribution degree (community) display area 41.

[0051] FIG. 5(B) shows an enlarged view of the contribution (community) display area 41 for the purpose of explanation. As shown, icons 52 for all users U who belong to the community are displayed. The contribution of each user U's icon 52 is indicated by the distance from the reference icon 51 at the center. The dotted frame and points shown in FIG. 5(B) can be hidden by using a display switching button (not shown). In this embodiment, the reference icon 51 is a car, but the design can be changed as desired.

[0052] This makes it possible to check at a glance the contributions of all users U who belong to the community. For example, in the illustrated community, there are 15 users U, and it is clear at a glance that there are approximately 3 to 9 users U who are close to the reference icon 51 (high contributions), and there are approximately 2 to 4 users U who are far from the reference icon 51 (low contributions).

[0053] Therefore, each user U can see at a glance how much he or she is contributing to the community, and as a result, if his or her level of contribution is lower than that of other users U, this can motivate that user U to make an effort to clean the interior of his or her car more, to refuel, and to be sure to rate other users U.

[0054] In short, the vehicle management system 1 and vehicle management method of the present invention can create peer pressure by displaying on the terminal 20 the correlation within the community based on the contribution of each user U. By creating peer pressure, it is possible to realize appropriate mutual monitoring and consideration within the community.

[0055] In addition, while typical car sharing services maintain the cleanliness of shared cars through discounts, kickbacks, or prizes, the vehicle management system 1 of the present invention makes it possible to encourage users U to clean the inside of shared car C thoroughly when they finish using it, or to refuel shared car C for the next user U, without incurring such costs and effort, thereby improving satisfaction throughout the community.

[0056] For example, the community shown in Figure 5(B) is a standard community with approximately 3-9 high-contribution users U and 2-4 low-contribution users U (the rest have medium contributions). However, as mentioned above, the low-contribution users U will begin to make an effort to improve their contributions independently through appropriate mutual monitoring and consideration. This will increase the contributions of all users U in the community, further improving the satisfaction of the entire community (see Figure 6(A)).

[0057] Also, even if the contribution levels of all users U belonging to the community are somewhat low (see Figure 6(B)), if one person feels a sense of crisis about the current situation and increases their contribution level, one or two other users U will also begin to voluntarily try to increase their contribution level through moderate mutual monitoring and consideration.

[0058] After the user U has finished using the shared car C, he or she will clean the interior of the shared car C thoroughly, refuel the shared car C (fill up the tank of fuel), and then carry out the return procedure for the shared car C (steps S50, S51). Specifically, the user U parks the shared car C at a designated return location and returns the shared car C by locking it and other procedures on the return screen (not shown) displayed on the terminal 20. These exchanges are carried out by the reservation management means 16 and the display means 15 of the server 10. In addition, the procedure for the user U to return the shared car C can be carried out using known technology.

[0059] Finally, a supplementary description will be given of the vehicle management system 1 according to this embodiment and the vehicle management method according to this embodiment.

[0060] (1. Regarding the question about the evaluation of the usage status of the previous user) In this embodiment, the questions for evaluating the usage status are posed with two choices (Good / Bad) regarding cleaning and refueling, but of course the question content and answer format are not limited to those exemplified. For example, the evaluation content (question content) may be about whether there is an odor (cigarettes, food) inside the car or whether personal belongings have been left behind. Furthermore, the answer format may also be, other than two choices, three choices (good / average / bad) or a five-point scale (1 star to 5 stars), etc.

[0061] Furthermore, the reason why user U answered "Bad" may be changed to "the fuel level was less than 25%," or user U may be allowed to select one of the reasons to answer, such as "the fuel level was less than 75%," "the fuel level was less than 50%," or "the fuel level was less than 25%." The reason why the user U answered "Good" can also be asked to the user U by the same procedure as that for asking the reason when the user U answered "Bad."

[0062] (2. Display format of contribution (community) display area) In the contribution (community) display area 41 illustrated in Figure 5(B), a reference icon 51 is displayed in the center, and icons 52 for all users U belonging to the community are displayed in a circle surrounding it, but the display format may also be as shown in Figure 7.

[0063] For example, in the example shown in FIG. 7(A), a display format is used in which icons 52 of a user U are arranged at various positions in a grid with a reference icon 51 at the center. On the other hand, in the example shown in Fig. 7(B), the reference icon 51 is at the top, and similar to the example shown in Fig. 7(A), the icons 52 of users U are arranged in various locations in a grid. In this case, it is clear at a glance that the higher the icon 52 of the user U, the higher the contribution level.

[0064] Of course, the display format of the contribution (community) display area 41 is not limited to the example shown, as long as it clearly visualizes the interrelationships of the contributions of users U within the community.

[0065] The request to acquire the community status and the display of the community status (steps S40 and S41) can be made at any time. Since the aforementioned contribution level and satisfaction level change from moment to moment, the user U can display the community status on the terminal 20 at any time.

[0066] The content displayed in the contribution level (individual) display area 43 can only be viewed by the user U himself, but some of the content, such as the satisfaction level display area 42, may be viewable by users U who do not belong to the community or those who have not yet applied for a subscription.

[0067] This allows those who have not yet signed up for a subscription to refer to the satisfaction level (score) of a certain community displayed in the satisfaction level display area 42 and select a community to belong to, for example, to join (apply for) a "community with a higher satisfaction level" rather than "a community with a station closest to home."

[0068] (3. User Icons) It is desirable that the icon 52 of the user U does not allow identification of the individual user U. If the icon 52 allows easy identification of the individual user U, other users U may feel disgust or resentment toward the user U who has a low level of contribution, which may lead to trouble.

[0069] In this embodiment, the icon 52 of the user U is assigned randomly by the control means 17 of the server 10 when the user U applies for a subscription.

[0070] Here, "not capable of identifying the individual user U" can be achieved by, for example, randomly changing the gender and age of the icon 52. In this embodiment, the icon 52 is a bust shot of a character (see FIG. 5(B) etc.), but it is also possible to use icons of various animals such as dogs, cats, monkeys, or plants such as flowers and trees, or geometric patterns.

[0071] The present embodiment described above is merely an example, and the layout of the screen displayed on the user's terminal and the arrangement of buttons can be modified as appropriate without departing from the spirit of the present invention. In addition, in this embodiment, the server 10 (display means 15) uses the web browser function of the terminal 20 to display various screens on the terminal 20, but it is also possible to install an application dedicated to the vehicle management system 1 on the terminal 20 so that reservations, ratings, and viewing of various information can be performed from the application. [Industrial Applicability]

[0072] The present invention is a vehicle management system that can make users aware of things like cleaning the inside of a shared car when they finish using it and refueling the car for the next user, thereby improving satisfaction throughout the community.It can be used in car sharing services, which are expected to become increasingly popular in the future, and is therefore industrially useful.
