The control unit 41 of the vehicle 40 may transmit the movement history of the vehicle detected by a positioning unit to the control device 20 as the action information.
In step S103, the control unit 21 of the control device 20 further acquires the action information by receiving the action information from the vehicle 40.
In step S104, the control unit 21 of the control device 20 determines the degree of interest in the predetermined element of the user U from the acquired action information. Any method may be adopted to determine the degree of interest.
The control unit 21 determines the user U's interest in saving, environmental protection, or a region from the purchase history acquired from a terminal device of a store. When the purchase history indicates that the number of times a product whose price has been reduced from a list price has been purchased within a predetermined period is equal to or greater than a predetermined value, the control unit 21 may determine that the user U has a high degree of interest in saving, and when the purchase history indicates that the number or times the product whose price has been reduced from the list price has been purchased is less than the predetermined value, the control unit 21 may be determine that the user U has a low degree of interest in saving.
When the purchase history indicates that the number of times a product having a predetermined mark indicating that the product conforms to the standard for environmental protection is purchased within a predetermined period is equal to or more than a predetermined value, the control unit 21 determines that the user U has a high degree of interest in environmental protection, and when the purchase history indicates that the number of times a product having a predetermined mark indicating that the product conforms to the standard for environmental protection is purchased within a predetermined period is less than the predetermined value, the control unit 21 may determine that the user U has a low degree of interest in environmental protection.

The control unit 21 may determine the degree of interest of the user U in each element of saving, environmental protection, or a region from information such as a browsing history of the Internet, the application used, and the like on the terminal device 30.
When the usage history of the device by the user U acquired from the device indicates that a ratio of the time during which the device is used in an energy saving mode among an operating time of the device is equal to or more than a predetermined value, the control unit 21 may determine that the user U has a high degree of interest in saving or environmental protection, and when the usage history of the device by the user U acquired from the device indicates that the ratio of the time during which the device is used in the energy saving mode among the operating time of the device is less than the predetermined value, the control unit 21 may determine that the user U has a low degree of interest in saving electricity or environmental protection. For example, when the usage history of the air conditioner as a device by the user U indicates that a ratio in which the air conditioner is used at a set temperature in which a difference with the outside temperature is less than a predetermined value within a predetermined period is equal to or more than a predetermined value, the control unit 21 may determine that the user U has a high degree of interest in saving or environmental protection, and when the usage history of the air conditioner as the device by the user U indicates that the ratio in which the air conditioner is used when the difference with the outside temperature is less than the predetermined value within the predetermined period, the control unit 21 may determine that the user U has a low degree of interest in saving electricity or environmental protection.
When the contract history of the gas, electricity, water, etc. of the user U acquired from the server device of the business operator indicates that the fee for each predetermined period is less than a predetermined value, the control unit 21 may determine that the user U has a high degree of interest in saving, and when the contract history of the gas, electricity, water, etc. of the user U acquired from the server device of the business operator indicates that the charge for each predetermined period is equal to or more than the predetermined value, the control unit 21 may determine that the user U has a low degree of interest in saving.
When the history of charging the vehicle 40 acquired from the vehicle 40 indicates that the price per unit electric power amount at the time of charging is less than a predetermined value, the control unit 21 may determine that the user U has a high degree of interest in saving, and when the history of charging the vehicle 40 acquired from the vehicle 40 indicates that the price per unit electric energy at the time of charging is equal to or more than the predetermined value, the control unit 21 may determine that the user U has a low degree of interest in saving electricity.
When the usage history of each device that is provided in the vehicle 40 and that is acquired from the vehicle 40 indicates that a usage time of each device within a predetermined period is less than a predetermined value, the control unit 21 may determine that the user U has a high degree of interest in saving or environmental protection, and when the usage history of each device that is provided in the vehicle 40 and that is acquired from the vehicle 40 indicates that the usage time of each device within the predetermined period is less than the predetermined value is less than the predetermined value within the predetermined period, the control unit 21 may determine that the user U has a low degree of interest in saving electricity or environmental protection. For example, when the usage history of the air conditioner provided in the vehicle 40 indicates that the ratio in which the air conditioner is used at a set temperature in which the difference with the outside temperature is less than the predetermined value within the predetermined period is equal to or more than the predetermined value, the control unit 21 may determine that the user U has a high degree of interest in saving or environmental protection, and when the usage history of the air conditioner provided in the vehicle 40 indicates that the ratio in which the air conditioner is used at the set temperature in which the difference with the outside temperature is less than the predetermined value within the predetermined period is less than the predetermined value in the predetermined period, the control unit 21 may determine that the user U has a low degree of interest in saving electricity or environmental protection. For example, when the movement history of the vehicle 40 acquired from the vehicle 40 indicates that the time during which the vehicle 40 is moving in the specific region in the predetermined period is equal to or longer than the predetermined value, the control unit 41 determines that the user U has a high degree of interest in the region, and when the movement history indicates that the time during which the vehicle 40 is moving in the specific region in the predetermined period is less than the predetermined value, the control unit 41 determines that the user U has a low degree of interest in the region.
The action information acquired from the vehicle 40 may include a history of a driving operation of the vehicle 40. In this case, when the history of the driving operation indicates that the ratio of a usage frequency of an idling stop function when the vehicle 40 is stopped is equal to or higher than a predetermined value, the control unit 21 may determine that the user U has a high degree of interest in saving or environmental protection, and when the history of the driving operation indicates that the ratio of the usage frequency of the idling stop function is less than the predetermined value, the control unit 21 may determine that the user U has a low degree of interest in saving electricity or environmental protection.
In step S105, the control unit 21 acquires the first information by generating the first information based on the result of the determination based on the action history. The control unit 21 may generate the first information based on only one of the action histories, or may generate the first information based on all of the action histories. The control unit 21 may generate the first information by scoring the interest of the user U for each element. In this example, the control unit 21 adds 1 point to all the action histories when it is determined that the user U has a high degree of interest in each element, and adds 0 points when it is determined that the user U as a low degree of interest in each element. The result is generated as the first information.
In this example, it is assumed that the control unit 21 acquires the purchase history of the product as the action history from the terminal device of the store and the usage history of the device in the vehicle 40 from the vehicle 40. It is assumed that the control unit 21 determines from the purchase history that the user U has a high degree of interest in environmental protection and the region, and determines from the usage history of the device that the user U has a high degree of interest in environmental protection. In this case, an example of the first information generated by the control unit 21 is shown below.
As shown in the above table, since it is determined that the user U is interested in environmental protection from both the purchase history and the usage history serving as the action history, two points are given to the environmental protection element. Further, since it is determined from the purchase history that the user U is interested in the region, one point is given to the element of the region. In this example, the first information is shown in a table format. However, the format of the first information is not limited to this.
Not limited to the above, the control unit 21 may generate the first information based on the result of the user U answering the degree of interest in a predetermined element. Specifically, the user U inputs, into the terminal device 30, the degree of interest in each of saving, environmental protection, or region serving as the predetermined elements. The predetermined elements may be preset or may be freely input by the user U. The control unit 21 may receive the input information from the terminal device 30, score the degree of interest, and generate the information as the first information in association with the user ID of the user U.
In step S106, the control unit 21 acquires the second information indicating the characteristic of each of the plurality of electric power plans for each item. Any method may be adopted for acquiring the second information. For example, the control unit 21 communicates with the server device of at least one electric power company, and receives information indicating at least one electric power plan provided by the electric power company. The electric power company may be an electric power company capable of supplying electric power to a residential region of the user U. The control unit 21 may acquire the second information by generating the second information based on the received information. Not limited to this, the control unit 21 may acquire the second information by receiving the second information from an external device.
An example of the second information generated by the control unit 21 is shown below.
As shown in the table above, the second information includes information about a plurality of electric power plans. In the above table, for each of the electric power plans A to C, a “fee” occurring in a predetermined period, an “emission factor” indicating a carbon dioxide emission amount per unit electric power amount, and a “ratio of electric power produced in a region” among the calculated electric power are shown as characteristics of the electric power plan. In this example, the region is assumed to be the region where the user lives. The control unit 21 may generate the second information by calculating the fee per unit electric power amount, the emission factor, and the ratio of the electric power produced in the region from the information indicating the electric power plan acquired from the electric power company. This makes it possible to generate the second information that allows equal comparison of the plurality of electric power plans provided by the plurality of electric power companies. The items indicating the characteristics of the electric power plan are not limited to this, and may include, for example, information indicating an evaluation by the user, a point rate of an affiliated company given in accordance with a usage amount, and the like. The control unit 21 stores the acquired second information in the storage unit 22.
In step S107, based on the interests of the user U, the control unit 21 identifies at least one of the electric power plans as the recommended electric power plan.
Any method may be adopted to identify the recommended electric power plan. In this example, the control unit 21 scores the characteristics of the electric power plan indicated by the second information for each item. Specifically, the control unit 21 first assigns a reference score to each item and converts each item into a score. As for the standard score, the lower the fee or the emission factor, the higher the given score, and the higher the ratio of the electric power produced in the region, the higher the given score. The conditions for giving a reference score may be set arbitrarily. For example, a threshold value may be set and a predetermined score may be given when the value of each item is equal to or higher than the threshold value. In this example, in the second information, an example in which the control unit 21 scores each item is shown below.
Next, the control unit 21 determines the correspondence between the element related to the interest of the user indicated by the first information and the item of the electric power plan. In this example, the elements indicated by the first information are “saving”, “environmental protection”, and “region”. The control unit 21 associates these elements with the items of a “fee occurring in a predetermined period”, an “emission factor”, and a “ratio of electric power calculated in the region”, respectively. The correspondence is not limited to this, and a plurality of elements and a single item may be associated with each other, or a single element and a plurality of items may be associated with each other. For example, when the item of the electric power plan further includes a “ratio of electric power derived from natural energy”, that two items that are the item thereof and the item of the “emission factor” may be associated with the element of “environmental protection”. Electric power derived from natural energy means electric power produced by hydroelectric power generation, wind power generation, solar power generation, etc.
Next, the control unit 21 calculates a score for each item of the electric power plan associated with each predetermined element. In the calculation, the control unit 21 weights the points for each item according to the associated elements. The conditions for weighting the points may be set arbitrarily. For example, the higher the degree of interest that the user U has regarding a predetermined element among the elements indicated by the first information, the higher the control unit 21 may set a weight on the associated item and perform scoring. In this case, for the same user U, the higher the degree of interest that the user U has regarding a predetermined element in comparison to other elements, the higher the control unit 21 may set a weight for the item corresponding to the element and perform scoring. The higher the degree of interest in the predetermined element of the target user U in comparison with the other users, the higher the control unit 21 may set the weight for the item of the element and perform scoring. In this way, the control associates the predetermined element with the item among the items, and the higher the degree of interest that the user U has regarding the predetermined element, the higher the control unit sets the weight for the item, and the control unit performs scoring.
Not limited to this, for example, when the electric power in the region is surplus, the control unit 21 may set a high weight to “the ratio of the electric power produced in the region” that is the item corresponding to the “region” and perform scoring.
In this example, it is assumed that the target user U has a high degree of interest in the element of “environmental protection” in comparison to the other users. The control unit 21 sets a value of 3 for the item of the “emission factor” corresponding to the element of “environmental protection”, sets a value of 1 as the weight for the item of the “fee” that corresponds to the element of “saving” and for the item of the “ratio of electric power calculated in the region” that corresponds to the element of the “region”, and calculates the weight by multiplying the reference score in Table 3. The control unit 21 adds up the calculated values of each item. Table 4 below shows the results of the control unit 21 that scored each item of each electric power plan indicated by the second information.
From Table 4, the electric power plan with the highest total value is Plan C. The control unit 21 identifies the electric power plan C having the highest total value as the recommended electric power plan. The number of recommended electric power plans identified by the control unit 21 is not limited to one. For example, the control unit 21 may identify all plans in which the calculated total value is equal to or greater than a predetermined value as the recommended electric power plan.
In step S108, the control unit 21 outputs information indicating the identified recommended electric power plan.
Any method may be adopted for outputting the information indicating the recommended electric power plan, and the control unit 21 may output the information by directly displaying the information on the output unit 25 of the control device 20. In this example, the control unit 21 outputs information indicating the electric power plan C serving as the recommended electric power plan, by transmitting the information to the terminal device 30 of the user U.
The information indicating the recommended electric power plan may include arbitrary information such as information indicating the characteristics of the recommended electric power plan for each item, discount information of the electric power company providing the recommended electric power plan, and the like. The control unit 21 may also output information indicating a fee that occurs for a predetermined electric power consumption amount when the recommended electric power plan is used. The predetermined electric power consumption amount may be freely set, and may be, for example, the electric power consumption amount of the user U last year. When the user U switches from the electric power plan that is currently used to the identified recommended electric power plan, the control unit 21 may calculate how much the fee occurred for a predetermined power consumption amount changes, and may output information indicating the calculated result by including the information indicating the calculated result in the information indicating the recommended electric power plan.
In step S109, the terminal device 30 receives information indicating the recommended electric power plan. The control unit 31 of the terminal device 30 causes the output unit 35 to display the information. This allows the user U to see information about the proposed recommended electric power plan. After that, the operation of the system 10 ends.
As described above, the control device 20 according to the present embodiment includes the control unit 21. The control unit 21 acquires first information indicating the interest of the user regarding a predetermined element, acquires second information indicating a characteristic of each of a plurality of electric power plans for each item, identifies at least one of the electric power plans as a recommended electric power plan based on the interest of the user, and outputs information indicating the identified recommended electric power plan to the user. The predetermined element includes at least one of saving, environmental protection, or a region.
According to the present embodiment, it is possible to estimate which element the user is interested in to what degree, and it is possible to provide an electric power plan that matches the user from a plurality of electric power plans, based on the estimation result. When the characteristics of the electric power plan match the elements that the user is interested in, the electric power plan is proposed, which makes it easier for the user to select the electric power plan that best suits his or her taste. Therefore, it is possible to improve the method of proposing an electric power plan suitable for the user.
As described above, in the control device 20 according to the present embodiment, the control unit 21 acquires the action information indicating the user's action history, and generates the first information based on the acquired action information. The action information includes the purchase history as the action history.
According to this embodiment, it is possible to estimate which element the user is interested in from the action of the user. Since the interest of the user is estimated from the actions unconsciously taken by the user, it becomes easier to propose an electric power plan that is more suitable for the user. Therefore, it is possible to improve the method of proposing an electric power plan suitable for the user.
As described above, the control device 20 according to the present embodiment further includes the communication unit 23 that communicates with the vehicle 40 on which the user has boarded. The control unit 21 acquires the action information from the vehicle 40 via the communication unit 23.
According to the present embodiment, the action information of the user can be acquired from the vehicle 40 on which the user has boarded, and the interest of the user can be estimated accurately based on more action information. As a result of the estimation, an electric power plan suitable for the user is provided. Thus, the user can easily select the proposed power plan. Therefore, it is possible to improve the method of proposing an electric power plan suitable for the user.
As described above, in the control device 20 according to the present embodiment, the item includes at least one of the fee occurring in the predetermined period, the emission factor indicating the carbon dioxide emission amount per unit electric power amount, and the ratio of electric power calculated in the region. The control unit 21 scores the characteristics of the electric power plan for each item and adds up the score, and identifies the electric power plan having the largest total value as the recommended electric power plan.
According to this embodiment, it is possible to more accurately evaluate and compare the characteristics of the electric power plans, regarding the items common to many electric power plans. As a result of the evaluation, an electric power plan suitable for the user is provided. Thus, the user can easily select the proposed power plan. Therefore, it is possible to improve the method of proposing an electric power plan suitable for the user.
As described above, in the control device 20 according to the present embodiment, the control unit 21 associates a predetermined element with an item, and the higher the interest of the user in the predetermined element, the higher the control unit 21 sets the weight for the associated item, and the control unit 21 performs scoring.
According to this embodiment, the electric power plan that suits the interest of the user is more highly evaluated and proposed to the user. For example, referring to Table 1, the user has a low degree of interest in “saving” and a high degree of interest in “environmental protection”. Further, referring to Tables 2 and 3, the electric power plan C finally identified by the control unit 21 has the highest “fee” but the lowest “emission factor”. Thus, it can be said that the electric power plan C is the electric power plan most suitable for the interest of the user, and when the electric power plan is proposed to the user, the user can easily select the electric power plan and make a contract. Therefore, it is possible to improve the method of proposing an electric power plan suitable for the user.
As described above, in the control device 20 according to the present embodiment, the control unit 21 outputs information indicating a fee occurred for a predetermined power consumption when the recommended electric power plan is used.
According to this embodiment, the user can confirm the cost occurred for the proposed electric power plan. Since the user is provided with a determination material when selecting an electric power plan, it becomes easier for the user to select the proposed power plan. Therefore, the method of proposing the electric power plan can be improved.
As a modification of the present disclosure, the control unit 21 may acquire a learning model that outputs the recommended electric power plan when the first information and the second information are input, and may output to the user, information indicating the recommended electric power plan output by the learning model.
Any method may be adopted for acquiring the learning model. For example, the control unit 21 uses, as learning data, a data set in which the first information and the second information are associated with the electric power plan finally selected by the user among the second information, so as to generate a learning model by using an arbitrary machine learning method. In this way, the control unit 21 may acquire the learning model that has learned a relationship between the first information and the second information and the electric power plan finally selected by the user among the second information. In this case, the control unit 21 inputs the acquired first information and the second information to the learning model, and outputs to the user, the information indicating the recommended electric power plan output by the learning model.
According to this modification, the learning model more accurately selects the recommended electric power plan that suits the user. Therefore, it is possible to improve the method of proposing an electric power plan suitable for the user.
