The road information 26 includes traffic jam information, traffic obstacle information, traffic regulation information, and construction information. The weather information 24, the map information 25, and the road information 26 are information received by the communication device 30 from a server or a data center that provides each information, and are updated at predetermined intervals.

  The controller 10 functions as a server of the proposal system 1 and executes control processing for managing and operating the car sharing system and control processing for providing an alternative to a user. The controller 10 has a ROM (Read Only Memory) 12 storing a program for executing a process for managing and operating the car sharing system and a process for managing and operating the proposal system, and executes a program stored in the ROM 12. A CPU (Central Processing Unit) 11 as an operation circuit functioning as a controller 10 and a RAM (Random Access Memory) 13 functioning as an accessible storage device are provided.

  The controller 10 includes a use receiving function, a purpose estimating function, an alternative creation function, a first required cost calculation function, a second required cost calculation function, an alternative necessity determination function, a notification function, and an alternative Execute function. The controller 10 is a computer that realizes each function by the cooperation of software for realizing the above function and the hardware described above. Hereinafter, each function realized by the controller 10 will be described with reference to FIGS.

  First, the use receiving function will be described. The controller 10 sequentially acquires use requests for requesting the use of one shared vehicle V from the user via the user terminal device 300 by the use reception function. The usage request includes information on the departure place and the destination specified by the user. For example, the user inputs the departure place as the boarding position of the shared vehicle V and the destination as the getting off position of the shared vehicle V to the input device 310 of the user terminal device 300. The user terminal device 300 transmits the input information to the proposal device 100 via the communication device 320. The information transmitted from the user terminal device 300 to the proposal device 100 includes not only the user's use request, but also the ID information of the user registered in advance by the user and the information of the current position of the user.

  FIG. 2 is an example of a scene in which a user inputs a destination using the user terminal device 300. In FIG. 2, the user corresponds to the user X. The user X has designated “large electric shop A” as the destination of the shared vehicle V. The information on the destination input by the user X is transmitted to the proposal device 100.

  Next, the purpose estimation function will be described. The controller 10 estimates the purpose to be achieved at the destination after the user moves to the destination using the shared vehicle V by the purpose estimation function. The controller 10 estimates the purpose of the user from the action history information 22 stored in the database 20. Examples of the purpose of the user include “purchase of goods at the destination”, “meal at the destination”, “play at the destination”, and “meeting at the destination”.

  For example, the controller 10 estimates the purpose of the user based on the browsing history of the website. When the controller 10 detects that the user is browsing a specific website from the browsing history of the website within a predetermined period before the use request is transmitted, the controller 10 sends the user to the destination based on the content of the website. Estimate the purpose for moving. For example, when the controller 10 detects a Web site on which a specific electric appliance is posted a plurality of times, the controller 10 estimates “purchase of electric appliance” as a user's purpose. Further, the controller 10 can estimate a more specific purpose than “purchase of an electric appliance” according to the content of the website and the browsing frequency of the website.

  FIG. 3 is a diagram illustrating an example of the estimation result of the user's purpose. FIG. 3 is a view of a scene after a lapse of a predetermined time from FIG. In FIG. 3, the controller 10 detects, from the browsing history of the Web site, a Web site on which a 32-inch television is posted, and estimates "purchase of a 32-inch television" as the purpose of the user. At this time, the controller 10 may further specify the TV maker and estimate “purchase of a 32-inch TV from the XX maker” as the purpose of the user. In the present embodiment, how specifically the user's purpose is estimated is not particularly limited, and the controller 10 estimates the user's purpose within an appropriate range according to the action history information 22.

  Further, for example, the controller 10 estimates the purpose of the user based on the search history of the user. When detecting a specific keyword from the search history of the user within a predetermined period before the use request is transmitted, the controller 10 estimates the purpose of the user from the specific keyword. For example, when the controller 10 detects a specific restaurant name as a keyword, the controller 10 estimates “meal” as the user's purpose. Further, the controller 10 can estimate a more specific purpose than “meal” in accordance with the content of the keyword and the search frequency. For example, when detecting the name of a restaurant mainly dealing with Chinese cuisine, the controller 10 may estimate “meal of Chinese cuisine” as the purpose of the user.

  Note that the controller 10 is not limited to estimating the purpose of the user from the information on the user's action history. For example, in addition to the user's action history, the controller 10 considers the user's preference and the user's family structure. The purpose may be estimated. For example, the controller 10 estimates the purpose of the user as “purchase of a 32-inch television”, and further estimates the manufacturer or the number of inches of the television based on the user's preference or the user's family structure. For example, when the user has previously registered a maker of a favorite electric appliance, the controller 10 may estimate the maker of the television with reference to the attribute information 21. Further, for example, when the user is a family of four (father, mother, and two children), the controller 10 may estimate a TV of a maker preferred by the user from TVs larger than a specific number of inches. Further, the controller 10 may estimate the purpose of the user in consideration of not only user-specific information but also weather information. For example, when an outdoor leisure facility and a restaurant are provided side by side at the destination specified by the user, the controller 10 uses the information that the current weather is raining instead of “playing at the destination” instead of “playing at the destination”. May be estimated as the user's purpose. The above-described method of estimating the purpose of the user is an example, and is not particularly limited. In addition to the action history of the user, the controller 10 includes information of the user's preference, information of the user's family structure, and The purpose of the user is estimated based on at least one of the weather information.

  Next, an alternative creation function will be described. The controller 10 creates an alternative for the user's purpose by using the alternative creation function. The controller 10 creates an alternative that can achieve the user's purpose instead of the present invention when the present invention is to move to the destination by the shared vehicle V. The alternatives include an alternative that can achieve the user's purpose using the shared vehicle V, and an alternative that can achieve the user's purpose without using the shared vehicle V. . Hereinafter, each of the alternatives will be described with an example, but for convenience of explanation, a case where the user's purpose is estimated to be “purchase of a product” is used.

  As an example of an alternative for achieving the purpose of "purchase of a product", "the common vehicle V is used to move to a place different from the destination (hereinafter, also referred to as another destination), "Purchase the goods sold at the destination", "Move to the destination using a means of transportation other than the shared vehicle V (hereinafter, also referred to as other transportation means) and purchase the goods sold at the destination", "Purchase products on the website without using the shared vehicle V", "Purchase products using the visiting service without using the shared vehicle V", "Delivery without using the shared vehicle V" Purchasing goods using services ". The controller 10 makes the achievement of the user's purpose the highest priority, and is not limited to using the shared vehicle V, examines various alternatives, and creates as many alternatives as possible.

  An example of an alternative using the shared vehicle V will be described. The controller 10 sets an alternative destination of the shared vehicle V as a substitute for the destination specified by the user, and moves to the alternative destination with the shared vehicle V and purchases a product at the alternative destination as an alternative. create. For example, the controller 10 searches for a store where a product can be purchased around the destination and sets the position of the store as an alternative destination. At this time, if a product can be purchased at a plurality of stores, the controller 10 sets a plurality of alternative destinations. Note that the search range centered on the destination is not particularly limited.

  FIG. 4 is a diagram illustrating an example of setting of an alternative destination. FIG. 4 is a diagram of a scene after a predetermined time has elapsed from FIG. In FIG. 4, the controller 10 searches for a large electronics store B that handles a 32-inch television, and sets the large electronics store B as an alternative destination.

  Further, the controller 10 is not limited to the movement by the shared vehicle V, and can create an alternative using other moving means. An example of an alternative using other transportation means will be described. In the present embodiment, the controller 10 acquires information on another transportation method and creates a movement to a destination by another transportation method as an alternative. Other modes of transportation include public transportation such as trains and buses, taxis, and the like. For example, the controller 10 acquires information on a route map of a bus or a train, and creates a guide to a destination using another means of transportation as an alternative. Note that the controller 10 may set an alternative destination and create a guide to the alternative destination using another means and purchase a product at the alternative destination as an alternative.

  In addition, the controller 10 can create an alternative in which the user does not move. An example of an alternative in which the user does not move will be described. In the present embodiment, the controller 10 searches for a website that sells the corresponding product by mail order, and creates a purchase of the product by mail order as an alternative. For example, the controller 10 searches for a store that handles the corresponding product at or near the destination, and determines whether the product can be purchased from the HP of the store. Then, when the product can be purchased, the controller 10 creates guidance of the store HP and purchase of the product from the HP as an alternative. Further, when the user is at a specific place such as a house or a company, the controller 10 searches for a service that allows a door-to-door sales to the user's house or the company, and stops using the shared vehicle V and sells a product by the door-to-door sales. A purchase may be made as an alternative.

  As described above, various alternatives can be cited, but in the following description, for convenience of explanation, a case using the shared vehicle V will be described as an example.

  Next, the first required cost calculation function will be described. The controller 10 calculates a first required cost by a first required cost calculating function. The first required cost can be rephrased as a burden on the user required until the user moves to the destination by the shared vehicle V and the user's purpose is achieved at the destination. The first required cost includes the cost, travel time, and travel distance required to achieve the purpose. The controller 10 calculates the first required cost based on at least one of a viewpoint related to cost, a viewpoint related to travel time, and a viewpoint related to travel distance. Specifically, the controller 10 calculates the first required cost based on at least one of road congestion information, road construction information, product price information, and service price information.

  For example, the controller 10 can include the price of a product sold at the destination and the price of a service provided at the destination in the first required cost. Further, the controller 10 includes, in the first required cost, not only the cost required for achieving the purpose itself, but also costs necessary for achieving the purpose, such as a parking fee at the destination and a toll road fee. Can be. Further, for example, the controller 10 obtains information on traffic congestion, traffic regulations, and traffic accidents on the road, and calculates an estimated time of arrival at the destination in consideration of the information. Then, the controller 10 can include the estimated arrival time in the first required cost. Further, for example, the controller 10 generates a traveling route from the current position of the user to the destination and measures the distance of the traveling route. Then, the controller 10 can include the distance of the traveling route of the shared vehicle V in the first required cost. In addition, the calculation method known at the time of filing of the present application can be appropriately used as the calculation method of the estimated arrival time in consideration of traffic congestion and the like and the calculation method of the distance of the traveling route.

  Next, the second required cost calculating function will be described. The controller 10 calculates a second required cost by a second required cost calculating function. In the case of using the alternative, the second required cost can be rephrased as a user burden required until the user's purpose is achieved. The second required cost includes a cost, a travel time, and a travel distance required to achieve the purpose, similarly to the first required cost element. The controller 10 calculates the second required cost based on at least one of a viewpoint related to cost, a viewpoint related to travel time, and a viewpoint related to travel distance. Specifically, the controller 10 calculates the second required cost based on at least one of road congestion information, road construction information, product price information, and service price information.

  For example, the controller 10 can include the price of a product sold at the alternative destination and the price of a service provided at the alternative destination in the second required cost. Further, for example, the controller 10 acquires information on traffic congestion, traffic regulations, and traffic accidents on the road, and calculates an estimated arrival time at the alternative destination in consideration of the information. Then, the controller 10 can include the estimated arrival time in the second required cost. Further, for example, the controller 10 generates a traveling route from the current position of the user to the alternative destination and measures the distance of the traveling route. Then, the controller 10 can include the distance of the traveling route of the shared vehicle V in the second required cost. Note that the same method or different methods may be used to calculate the first required cost and the second required cost.

  FIG. 5 is a diagram illustrating an example of a calculation example of the first required cost and the second required cost. FIG. 5 is a view of a scene after a predetermined time has elapsed from FIG. The scene shown in FIG. 5 is a scene in which the reference time is 16:00, a traffic jam occurs on the road around the large electronics store A, and no traffic jam occurs on the road around the large electronics store B. The controller 10 obtains the traffic jam information on the road around the large electronics store A by the first required cost calculation function, and sets the estimated time of arrival at the large electronics store A at 16:45 in consideration of the influence of the traffic jam. Calculated. Further, the controller 10 acquires the price information of the 32-inch television handled by the large electronics store A, and calculates the cost for achieving the purpose as 50,000 yen. In FIG. 5, the first required cost includes the estimated arrival time at the large electronics store A and the selling price of the television at the large electronics store A.

  On the other hand, in FIG. 5, the controller 10 calculates the estimated arrival time at the large electronics store B as 16:30 by the second required cost calculation function. Further, the controller 10 obtains information on the price of the 32-inch television handled by the large electronics store B, and calculates the cost for achieving the purpose as 40,000 yen. In FIG. 5, the second required cost includes the estimated time of arrival at the large electronics store B and the selling price of the television at the large electronics store B.

  Next, an alternative solution necessity determination function will be described. The controller 10 uses the alternative necessity determination function to determine whether it is necessary to provide an alternative to the user who has designated the destination. In the present embodiment, the controller 10 compares each element constituting the first required cost with each element constituting the second required cost, and based on the comparison result, the alternative is compared with the movement to the destination. If it is determined that the user's satisfaction with the achievement of the purpose can be improved, it is determined that an alternative proposal is necessary. Conversely, if the controller 10 determines that the alternative cannot improve the user's satisfaction with the achievement of the purpose as compared to the movement to the destination, the controller 10 determines that the proposal of the alternative is unnecessary.

  For example, the controller 10 compares the cost included in the first required cost with the cost included in the second required cost, and determines whether the cost included in the second required cost is lower than the cost included in the first required cost, We judge that the proposal of the plan is necessary. Conversely, when the cost included in the second required cost is higher than the cost included in the first required cost, the controller 10 determines that the proposal of the alternative is unnecessary. Further, for example, the controller 10 compares the moving distance included in the first required cost with the moving distance included in the second required cost, and determines that the moving distance included in the second required cost is the moving distance included in the first required cost. If it is shorter than this, it is judged that an alternative proposal is necessary. Conversely, when the moving distance included in the second required cost is longer than the moving distance included in the first required cost, the controller 10 determines that it is not necessary to propose an alternative. Further, for example, the controller 10 compares the travel time included in the first required cost with the travel time included in the second required cost, and determines that the travel time included in the second required cost is included in the first required cost. If it is shorter than this, it is judged that an alternative proposal is necessary. Conversely, when the travel time included in the second required cost is longer than the travel time included in the first required cost, the controller 10 determines that it is not necessary to propose an alternative. It is not necessary to make a judgment using all the comparison results, and it is necessary to propose an alternative based on one of the comparison result about the cost, the comparison result about the travel distance, and the comparison result about the travel cost. What is necessary is just to judge.

  FIG. 6 is a diagram illustrating an example of a comparison result of the first required cost and the second required cost. FIG. 6 is a diagram of a scene after a lapse of a predetermined time from FIG. In FIG. 6, the controller 10 compares the estimated time of arrival at the large electronics store A with the estimated time of arrival at the large electronics store B, and as a result, determines that the alternative can purchase the television earlier. ing. The controller 10 compares the price of the television at the large electronics store A with the price of the television at the large electronics store B, and as a result, determines that the alternative solution can reduce the cost. Then, the controller 10 replaces the transfer to the large electric store B and the purchase of the television at the large electric store B with the transfer to the large electric store A and the purchase of the television at the large electric store A from the two comparison results. As an alternative, it is determined that it is necessary to propose to the user X.

  It should be noted that the determination of the necessity of proposing an alternative need not be performed based only on the above-described factors of the cost, the moving distance, and the moving time. The controller 10 determines whether it is necessary to propose an alternative based on at least one of user's preference and weather information in addition to the comparison result between the first required cost and the second required cost. Is also good. Using the example of FIG. 6, for example, if the purchase history of the user X includes purchase cancellation information via the website of the large electronics store B, the controller 10 It may be determined that the shop is not the electric shop B. In this case, the controller 10 may prioritize the user's preference over the cost, travel distance, and travel time comparison results and determine that no alternative is required. Further, for example, when the user has previously transmitted the preference information to the proposal device 100, the controller 10 determines whether or not it is necessary to propose an alternative based on the pre-registered user preference information. May be. Further, the controller 10 may weight comparison results on the cost, travel distance, and travel time, and information on user preference and weather, and determine whether alternative proposals are necessary.

  Further, for example, when the purpose of the user is leisure and the distance to the destination is a predetermined distance or more, that is, when the user goes far using the shared vehicle V, the controller 10 considers the weather information. Alternatively, the necessity of proposing an alternative may be determined. For example, when the outdoor facility is set as the destination, and when the weather in the area including the alternative destination is rainy, the controller 10 may determine that the proposal of the alternative is unnecessary.

  Next, the notification function will be described. The controller 10 proposes an alternative to the user via the user terminal device 300 by the notification function. For example, the controller 10 may provide information on an alternative destination, an estimated time of arrival at the alternative destination, a travel route to the alternative destination, information on products that can be purchased at the alternative destination, and information on services provided at the alternative destination. Proposal to the user, including alternatives.

  FIG. 7 is a diagram illustrating an example of notification of an alternative to a user. FIG. 7 is a view of a scene after a predetermined time has elapsed from FIG. In FIG. 7, the controller 10 proposes, to the user X, via the user terminal device 300, the position of the large electronic store B, the traveling route to the large electronic store B, and the estimated time of arrival at the large electronic store B. are doing.

  Next, the alternative execution function will be described. The controller 10 executes the alternative when the user accepts the alternative by the alternative execution function. For example, the controller 10 transmits the traveling route to the alternative destination to the shared vehicle V. Thereby, for example, when the shared vehicle V is a vehicle that is automatically driven, the destination of the shared vehicle V is changed from the destination specified by the user to the alternative destination.

  FIG. 8 is a diagram illustrating an example when the alternative is executed. FIG. 8 is a view of a scene after a lapse of a predetermined time from FIG. In FIG. 8, the user X gets on the shared vehicle V and moves to the large electronics store B. Thereafter, the user X arrives at the large electronics store B at the estimated arrival time calculated by the controller 10, and can purchase the television at a lower price than purchasing at the large electronics store A.

  Subsequently, a control procedure of the alternative proposal system according to the present embodiment will be described with reference to FIG. FIG. 9 is a flowchart illustrating a control procedure of the alternative proposal system according to the present embodiment.

  In step S101, the controller 10 acquires information on the destination set by the user via the user terminal device 300.

  In step S201, the controller 10 estimates the purpose achieved by the user at the destination from the information on the destination of the user acquired in step S101 and the action history of the user stored in the database 20. For example, the controller 10 estimates the purpose of the user from the browsing history of the Web site, the transmission history and reception history of the mail, the transmission history and the reception history of the telephone.

  In step S103, the controller 10 creates an alternative plan that is different from the present case in which the shared vehicle V moves to the destination and that can achieve the user's purpose estimated in step S202. I do. For example, when the user's purpose is to purchase a product, the controller 10 sets a place where the product can be purchased as an alternative destination of the shared vehicle V, moves to the alternative destination, and purchases a product at the alternative destination. Is created as an alternative.

  In step S104, the controller 10 calculates a first required cost and a second required cost. For example, when the purchase of a product is the purpose of the user, the controller 10 calculates the estimated arrival time at the destination and the price of the product sold at the destination as the first required cost. Further, the controller 10 calculates the estimated time of arrival at the alternative destination and the price of the product sold at the alternative destination as the second required cost.

  In step S105, the controller 10 determines whether to propose an alternative. For example, the controller 10 compares the first required cost and the second required cost calculated in step S104, and if the second required cost is lower than the first required cost, improves the user's satisfaction with achieving the purpose. It is judged that it can be made to be possible, and that it is necessary to propose an alternative. Examples of the case where the second required cost is lower than the first required cost include that the price of the product sold at the alternative destination is lower than the price of the product sold at the destination, An example is that the estimated time of arrival at the destination is earlier than the estimated time of arrival at the destination. Note that the determination criterion is an example and is not particularly limited. For example, the controller 10 may determine whether or not to propose an alternative in consideration of the user's preference. If it is determined that the proposal of the alternative is necessary, the process proceeds to step S106, and if it is determined that the proposal of the alternative is unnecessary, the control process of the proposal system ends.

  In step S106, the controller 10 proposes to the user the alternative created in step S103. For example, the controller 10 causes the display device 330 of the user terminal device 300 to display information on the alternative destination, an estimated time of arrival at the alternative destination, a price of a product sold at the alternative destination, and the like.

  In step S107, the controller 10 determines whether the consent of the alternative has been received from the user. For example, the controller 10 determines whether or not the user has accepted the consent of the alternative before the predetermined time elapses from the notification of the alternative. If the consent of the alternative has been accepted, the process proceeds to step S108. If the consent of the alternative has not been accepted, the control process of the proposal system ends.

  In step S108, the controller 10 executes the alternative. For example, the controller 10 changes the destination of the shared vehicle V by transmitting the traveling route to the alternative destination to the shared vehicle V. When the processing in step S108 ends, the control processing of the proposal system ends.

  As described above, in the present embodiment, as the proposal system 1, the controller 10, the user terminal device 300 that allows the user to input the destination of the vehicle, and the database 20 in which the user's action history is stored. The system including the above has been described as an example. The controller 10 obtains information on the destination of the shared vehicle V from the user terminal device 300, and estimates the purpose that the user should achieve at the destination using the user's action history information 22 and the information on the destination, A first requirement required to create an alternative plan that is different from the present plan in which the shared vehicle V moves to the destination and is a plan that can achieve the purpose, and is required to achieve the purpose using the present plan. Calculate the cost and the second required cost required to achieve the purpose using the alternative, compare the first required cost with the second required cost, and, based on the comparison result of the first required cost and the second required cost, If it is determined that the alternative can improve the user's satisfaction with the achievement of the object as compared with the present invention, the alternative is proposed to the user. Thereby, when it is determined that the user's satisfaction can be improved by using the alternative, the alternative is proposed, so that the user can actively adopt the alternative and satisfy the user. The degree can be improved.

  Further, in the present embodiment, the first required cost and the second required cost include at least one of the cost required to achieve the purpose of the user, the travel distance of the user, and the travel time of the user. . Thereby, based on at least one of the viewpoint of cost, the viewpoint of the length of travel distance, and the viewpoint of the length of travel time, it is appropriately determined whether the satisfaction of the user can be improved. You can judge.

  Further, in the present embodiment, the user terminal device 300 is a device possessed by the user and a device that communicates with the controller 10 via the Internet 400. Further, the controller 10 proposes an alternative to the user via the user terminal device 300 before the shared vehicle V leaves for the destination. As a conventional technique for proposing an alternative, there is known a technique for proposing an alternative destination during travel when it is determined that the purpose cannot be achieved within a scheduled time after the shared vehicle V starts moving to the destination. ing. According to this conventional technique, the user cannot start an alternative plan unless the user starts moving in the shared vehicle V and does not meet the condition that the purpose cannot be achieved within the scheduled time. On the other hand, in the present embodiment, a plurality of options can be given to the user in advance because an alternative is proposed before traveling by the shared vehicle V. For example, when an alternative that can purchase a product at a price lower than the user's expectation is proposed, the user can be satisfied, and as a result, the use of the proposed system can be expanded.

  In addition, in the present embodiment, the controller 10 determines the purpose of the user based on at least one of the user's preference, the user's family structure, and the weather information in addition to the user's action history information 22. presume. As a result, the user's purpose can be more specifically estimated, and the estimation accuracy can be improved.

  Further, in the present embodiment, the controller 10 sets a place other than the destination designated by the user and which can achieve the user's purpose as an alternative destination of the shared vehicle V, and A plan to move to an alternative destination by the vehicle V is created as an alternative. Thus, for example, even when the shared vehicle V is used in a place where there is no intuition of the land, the user can know that the purpose can be achieved in a place other than the place expected, and give the user a sense of security. be able to. As a result, use of the proposed system can be expanded.

  Further, in the present embodiment, the controller 10 creates a plan in which the user does not use the shared vehicle V as an alternative plan. Thus, the user who has planned to move in the shared vehicle V can know that the purpose can be achieved by other means, and can give the user more options. Specifically, in the present embodiment, the controller 10 generates a plan using at least one of the home delivery service and the visiting service as an alternative plan. Thus, the user can achieve the purpose without moving, and can use the time necessary for the movement for another purpose, thereby improving the user's satisfaction.

  In the present embodiment, the controller 10 creates a plan for moving to the destination using a moving means other than the shared vehicle V as an alternative plan. Thus, the user who has planned to travel by the shared vehicle V can know how to travel to the destination by another transportation means, and can give the user more options.

  Furthermore, in the present embodiment, the controller 10 compares the cost included in the first required cost with the cost included in the second required cost, and the travel distance and the second required cost included in the first required cost. Necessity of proposing an alternative based on at least one of the comparison result of the travel distance included in the first required cost and the comparison result of the travel time included in the second required cost and the travel time included in the second required cost. Judge. Since the necessity of the proposal is determined based on the factors that affect the user's satisfaction, the necessity of the proposal of the alternative can be appropriately determined.

  In addition, in the present embodiment, in addition to the comparison result of the first required cost and the second required cost, the controller 10 achieves the purpose based on at least one of the user's preference and weather information. It is determined whether the user's satisfaction with can be improved. Thereby, not only objective factors but also subjective factors of the user are determined, so that a different determination can be made for each user.

  Further, in the present embodiment, the controller 10 determines the first required cost and the second required cost based on at least one of road congestion information, road construction information, product price information, and service price information. Calculate the cost. Thus, it is possible to calculate the user's burden until the purpose is achieved, taking into account factors that change with time, such as traffic congestion on the road and price reductions for a limited time.

  The embodiments described above are described for facilitating the understanding of the present invention, but are not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

  For example, in this embodiment, the alternative proposal system has been described on the assumption that the user has one purpose. However, the purpose achieved by the user at the destination is not necessarily limited to one, and the purpose to be achieved at the destination is not limited to one. Alternatively, there may be additional purposes. A modified example prepared for such a case will be described with reference to FIG.

  FIG. 10 is a diagram illustrating an example of an estimation result of a user's purpose performed by an alternative proposal system according to a modification. FIG. 10 is a scene corresponding to FIG. 3 and is a diagram of a scene after a lapse of a predetermined time from FIG. In FIG. 10, the controller 10 detects, from the browsing history of the website, a website on which a 32-inch television is posted, and estimates "purchase of a 32-inch television" as the purpose of the user.

  In this situation, the controller 10 according to the modified example determines whether or not there is an accompanying purpose to be achieved in the large electronics store A in addition to the estimated purpose, and when it is determined that the accompanying purpose exists, the controller 10 estimates. Create alternatives that can achieve not only the objectives, but also the associated objectives.

  In the example of FIG. 10, the controller 10 determines, for example, from the user's mail transmission history and reception history that the user is scheduled to meet with the family, and that the family 10 is at a leisure facility provided on the roof of the large electronics store A. Suppose you confirm your experience. In this case, the controller 10 estimates that the user has a purpose of "playing at the leisure facility of the large-sized electric store A" separately from the purpose of "purchase of the 32-inch television". Then, the controller 10 searches for a leisure facility equivalent to the leisure facility of the large-sized electric store A, and sets the location of the corresponding leisure facility (for example, the leisure facility C) as an alternative destination. In this case, as an alternative to achieve the purpose of “purchase of a 32-inch television at the large electronics store A”, the controller 10 moves to the large electronics store B by the shared vehicle V and sets the television at the large electronics store B As an alternative to achieve the attendant purpose of "playing at leisure facilities of large electronics store A", the common vehicle V may be used to move to leisure facilities C and play at leisure facilities C. suggest.

  As described above, in the modified example, the controller 10 determines whether or not there is an accompanying purpose to be achieved in the large-sized electronics store A in addition to the estimated purpose, and when it is determined that the accompanying purpose exists, the controller 10 estimates. Create alternatives that can achieve not only the objectives, but also the associated objectives. As a result, it is possible to propose an alternative having a higher use value to the user, so that the use of the proposal system can be expanded.

  Also, for example, in the above-described embodiment, an example has been described in which the first required cost and the second required cost are calculated using road congestion information, road construction information, product price information, and service price information. Elements included in the first required cost and the second required cost are not limited to these. For example, a time zone in which a shop or facility that sells goods or provides a service can be used, a degree of congestion in each time zone, and a reputation of the shop or facility may be considered. This makes it possible to make a more realistic judgment in determining whether or not to propose an alternative, and to make a judgment that suits the user's feeling.

  Further, for example, in the above-described embodiment, the behavior history of the user is described using the behavior history information 22. However, the behavior history of the user may include the system usage history information 23. In this case, when determining whether or not to propose an alternative, the controller 10 may determine that an alternative is necessary if, for example, the user has previously accepted the alternative. Conversely, if the user has not previously accepted the proposal for the alternative, the controller 10 may determine that the proposal for the alternative is unnecessary. As a result, it is possible to prevent a proposal of an alternative from being made constantly and making the user uncomfortable. In addition, the controller 10 may perform weighting according to the frequency of acceptance and reflect the weight in the determination of necessity. As a result, it is possible to make an appropriate determination according to the past user's response.

  For example, in the present specification, the proposal system according to the present invention will be described using the proposal system 1 as an example, but the present invention is not limited to this. In the present specification, the controller according to the present invention will be described by taking the controller 10 as an example, but the present invention is not limited to this. Further, in the present specification, the database according to the present invention will be described using the database 20 as an example, but the present invention is not limited to this. Also, in the present specification, the terminal according to the present invention will be described using the user terminal device 300 as an example, but the present invention is not limited to this. Moreover, although this specification demonstrates the vehicle which concerns on this invention to the common vehicle V as an example, this invention is not limited to this.
