Even when the entire apparatus is in a stopped state (sleep state), the units 4a to 4f operate in the low power consumption operation mode.

  The time setting unit 4a sets the set time when the setting operation of the setting time by the user is received by the operation receiving unit 23 of the vehicle side device 2 or the operation receiving unit 25 of the mobile terminal 3. The set time is a time that the user desires to make the charge amount of the battery 19 reach the set charge amount by that time, for example, a use start time (boarding time) of the vehicle. The charge amount setting unit 4b sets the set charge amount when the setting operation of the set charge amount by the user is received by the operation receiving unit 23 of the vehicle side device 2 or the operation receiving unit 25 of the portable terminal 3. The set charge amount is a charge amount that the user desires to make the charge amount of the battery 19 reach the charge amount.

  The server 24 has a function of managing weather information in a database for each region (for example, for each section of a predetermined range) in cooperation with an organization that predicts the weather, for example. When the server 24 receives the weather information request signal transmitted from the outside via the communication network, the server 24 extracts the weather information at the position specified by the received weather information request signal. Then, the server 24 distributes the weather information response signal including the extracted weather information to the transmission source of the weather information request signal via the communication network. The weather information managed by the server 24 includes information on the amount of solar radiation (including the sunrise time and sunset time), the amount of clouds (cloud movement), and the like.

  Now, in a vehicle equipped with the vehicle-side device 2 having the above-described configuration, the battery 19 needs to be charged to enable traveling. In the present embodiment, the user operates the vehicle side device 2 or the portable terminal 3 to input a set time, a set charge amount, and a set item related to charging. Here, a case where the user operates the mobile terminal 3 to input a set time, a set charge amount, and a set item related to charging will be described. The user reads the setting input screen 31 shown in FIG. 2 by operating the mobile terminal 3. On the setting input screen 31, a time setting area 32, a charge amount setting area 33, and an item setting area 34 are displayed.

  In this case, the user operates the up key 32a and the down key 32b in the time setting area 32 to input the set time, and operates the up key 33a and the down key 33b in the charge amount setting area 33 to input the set charge amount. Then, the setting key is input by operating the up key 34a and the down key 34b in the item setting area 34. The set time can be selected in units of 1 minute, for example. As the set charge amount, for example, either “full charge” or “half charge” can be selected. As the setting item, for example, “charge priority” or “time priority” can be selected. In the example of FIG. 2, the user selects “9:30” as the set time, selects “full charge” as the set charge amount, and selects “charge priority” as the setting item. In this way, the user can input the set time, the set charge amount, and the set items related to charging by operating the mobile terminal 3.

  A similar setting input screen is displayed also on the vehicle side device 2, and the user can input a set time, a set charge amount, and a setting item related to charging by operating the vehicle side device 2. That is, the user can input the set time, the set charge amount, and the set items related to charging regardless of whether or not the user is staying in the vehicle interior (regardless of location). In addition, if it is linked with a well-known scheduler application installed in the mobile terminal 3, the planned outing time or destination registered in the scheduler application is read, the outing time is set as the set time, and the user goes out from the current position. A configuration may be adopted in which the set time and the set charge amount are automatically input by calculating the required charge amount according to the distance to the previous point and setting it as the set charge amount. That is, the set time includes any of the time directly input by the user and the scheduled time of going out registered in the scheduler application, and may be input in any manner as long as the time can be specified. The set charge amount includes both the charge amount directly input by the user and the charge amount calculated from the distance to the destination registered in the scheduler application. It may be input in various ways.

  Next, the operation of the above configuration will be described with reference to FIGS. In connection with the present invention, the control unit 4 performs a charging schedule determination process and an operation control process at predetermined intervals. Hereinafter, each processing will be described.

(1) Charging schedule determination process When the charging schedule determination process starts, the control unit 4 determines whether or not a charging request has occurred (S1). If it determines with the charge request | requirement not having generate | occur | produced (S1: NO), the control part 4 will complete | finish a charge schedule determination process, will return, and will wait for the next start timing of a charge schedule determination process. Here, for example, when the user operates the mobile terminal 3 to input a set time, a set charge amount, and a set item, and performs an operation of transmitting the input content using the vehicle side device 2 as a transmission destination (destination). The portable terminal 3 transmits a charge request signal including the input content to the vehicle side device 2 via the communication network.

  In the vehicle side device 2, if the control unit 4 determines that the charging request signal transmitted from the mobile terminal 3 has been received by the wireless communication unit 10, it determines that a charging request has occurred (S1: YES), and the charging request. The input content included in the signal is specified (S2). And the control part 4 sets setting time, setting charge amount, and a setting item according to the specified input content (S3, 1st procedure, 2nd procedure), and each charging part 5-7 (plug-in charge) The charging schedule of the unit 5, the non-contact charging unit 6 and the solar charging unit 7) is determined as follows.

  The control unit 4 specifies the current time by the time measuring function, and inputs coordinates indicating the current position of the vehicle from the CAN communication unit 13 to specify the current position of the vehicle (S4). Next, the control unit 4 inputs and acquires the charge amount of the battery 19 at that time from the charge amount detection unit 8 (S5), and calculates the difference between the charge amount of the battery 19 and the set charge amount at that time. Then, the charge amount required until the charge amount of the battery 19 reaches the set charge amount is calculated as the required charge amount (S6).

  Next, the control unit 4 performs operation confirmation (confirmation of whether or not operation is possible) of the charging units 5 to 7 (S7). Specifically, the control unit 4 outputs a test command request to each of the charging units 5 to 7, for example. When each charging unit 5-7 receives a test command request from the control unit 4, it performs its own operation diagnosis, and if the diagnosis result is positive (operable), a test result response indicating that the test result is positive Is output to the control unit 4, and if the diagnosis result is negative (operation is impossible), a test result response indicating that the test result is negative is output to the control unit 4. When a test result response indicating that the test result is positive is input, the control unit 4 specifies that the charging unit that is the output source of the test result response is operable, and indicates that the test result is negative. When a test result response is input, the charging unit that is the output source of the test result response is identified as being inoperable.

  Next, the control unit 4 is different from the plug-in charging unit 5 and the non-contact charging unit 6 in terms of the solar charging unit 7, and its operation is affected by the weather (it depends on the weather), It is determined whether or not the charging unit 7 is specified as operable (S8). When the control unit 4 determines that the solar charging unit 7 has been identified as being operable (S8: YES), a weather information request signal including the current position of the vehicle and the set time is transmitted from the wireless communication unit 10 via the communication network. To the server 24 (S9), and waits for reception of the weather information response signal from the server 24 (S10).

  When the server 24 receives the weather information request signal transmitted from the vehicle side device 2 in this manner, the server 24 extracts the weather information from the current time at the current position of the vehicle to the set time included in the received weather information request signal. To do. And the server 24 transmits the weather information response signal containing the extracted weather information to the vehicle side apparatus 2 via a communication network.

  When determining that the weather information response signal transmitted from the server 24 has been received by the wireless communication unit 10 (S10: YES), the control unit 4 determines the set time from the current time at the current position of the vehicle included in the weather information response signal. Until the weather information is identified (S11). The control unit 4 analyzes the specified weather information and determines whether or not the solar charging unit 7 can be used (S12). If the control part 4 receives solar radiation enough and determines that the solar charging part 7 can be used (S12: YES), the result of the operation check of each charging part 5-7 and the current position at the current position of the vehicle A charging schedule is determined including weather information from the time to the set time (S13, third procedure).

  That is, as shown in FIG. 5, the control unit 4 specifies the change in the amount of solar radiation and the amount of clouds in a period of one day (24 hours) from the weather information, and charges by the solar charging method. A possible charge amount (amount of power that can be generated) is calculated, and a charge schedule is determined in consideration of the calculated charge amount. In other words, when the charge priority is set, the control unit 4 gives priority to the solar charge method with the lowest power charge (cost) per unit charge amount, and determines the charge amount by the solar charge method as the required charge amount. The charging schedule is determined so as to compensate for the shortage deducted from the above by plug-in charging and non-contact charging. On the other hand, if the control unit 4 determines that the solar charging unit 7 is specified as not operable (S8: NO), or determines that the solar charging unit 7 cannot be used without receiving sufficient sunlight. (S12: NO), the result of the operation check of each charging unit 5, 6 is taken into consideration, but the charging schedule is determined without including the weather information (S14, third procedure).

  As a specific example, refer to FIG. 6 for a case where each of the charging units 5 to 7 is operable, the vehicle is parked outdoors (where sunlight can be received), and sunlight can be expected. I will explain. Also, here, the electricity charge is relatively cheap during the late night and early morning hours, and the electricity charge required for charging by the plug-in charging method is cheaper than the electricity charge required for charging by the non-contact charging method, while the daytime It is assumed that the power charge is relatively high in the time zone, and the power charge required for charging by the plug-in charging method is higher than the power charge required for charging by the non-contact charging method. In this case, the control unit 4 calculates the necessary charge amount (V2-V1) by subtracting the current charge amount (V1) of the battery 19 from the set charge amount (target charge amount, V2), and the power charge for each time zone The time (t0) at which charging is started is determined with reference to the power rate table in which is stored.

  In the example of FIG. 6, since the time (t0) at which charging is started is a time zone of midnight and early morning, the control unit 4 determines the time (t0) at which charging is started by charging by the plug-in charging method and by the solar charging method. It is determined as the time to start charging. Next, the control unit 4 sets the time (t1) at which the power rate changes from the late-night / early-morning time zone to the daytime time, and ends the charging by the plug-in charging method and at the same time the charging by the non-contact charging method is started. Determine as. Subsequently, the control unit 4 determines a time (t2) at which the charging by the solar charging method can be expected to be sufficient thereafter as the time for ending the charging by the non-contact charging method. And the control part 4 determines setting time (t3) as time which complete | finishes the charge by a solar charge system. In FIG. 6, the charge amount in the “A” region indicates the original charge amount, the charge amount in the “B” region indicates the charge amount charged by the plug-in charging method, and the charge amount in the “C” region. The charge amount indicates the charge amount charged by the non-contact charge method, and the charge amount in the region “D” indicates the charge amount charged by the solar charge method.

  When determining the charging schedule in this manner, the control unit 4 determines whether or not the user is staying in the vehicle compartment (boarding) (S15). When the control unit 4 determines that the user is not staying in the vehicle interior (S15: NO), the control unit 4 transmits a schedule notification signal including the calculated charging schedule from the wireless communication unit 10 to the portable terminal 3 via the communication network. (S16) Waiting for reception of the charge execution command signal from the portable terminal 3 (S17).

  When the mobile terminal 3 receives the schedule notification signal transmitted from the vehicle-side device 2 in this manner, the mobile terminal 3 notifies the charging schedule included in the schedule notification signal by the notification unit 28. That is, the mobile terminal 3 displays a charging schedule notification screen 41 as shown in FIG. On the charging schedule notification screen 41, an indicator 42 indicating the transition of each charging amount according to each charging method until the charging amount of the battery 19 reaches the set charging amount, and each when the charging amount of the battery 19 reaches the set charging amount Indicator 43 indicating the classification (ratio) of each charging amount according to the charging method, classification between the charging amount by fossil energy and the charging amount by non-fossil energy (clean energy) when the charging amount of the battery 19 reaches the set charging amount ( An index 44 indicating the ratio) is displayed. Charging by non-fossil energy is charging that does not require fuel costs, and is charging using wind power, wave power, geothermal heat, etc. in addition to charging using sunlight. In the example of FIG. 7, the time (t0) at which charging is started is “6:10”, and the time (t1) at which the power rate changes from the late-night early morning time zone to the daytime time zone is “7:00”. Hereafter, the case where the time (t2) at which it can be expected that only charging by the solar charging method is sufficient is “8:20”. Further, in the illustration of FIG. 7, when the charge amount of the battery 19 reaches the set charge amount, the charge amount by the plug-in charge method is “50%”, and the charge amount by the non-contact charge method is “20%”. Yes, the case where the charging amount by the solar charging method is “30%” is illustrated. Moreover, in the illustration of FIG. 7, the charge amount by fossil energy is “20%”, and the charge amount by non-fossil energy is “80%”. It shows that it is friendly to the global environment, so that the ratio of the charge amount by non-fossil energy is large and the ratio of the charge amount by fossil energy is small.

  Furthermore, a confirmation button 45 is displayed on the charging schedule notification screen 41. In this case, the user can instruct execution of charging according to the charging schedule by operating the confirmation button 45. When the user performs an operation to instruct execution of charging according to the charging schedule, the portable terminal 3 transmits a charging execution instruction signal indicating that to the vehicle side device 2 via the communication network.

  When determining that the wireless communication unit 10 has received the charge execution command signal transmitted from the portable terminal 3 in this way (S17: YES), the control unit 4 determines the calculated charging schedule (S18), End the schedule determination process and return. The charging schedule notification screen 41 may display additional information such as a power charge necessary for charging.

  On the other hand, when the control unit 4 determines that the user is staying in the vehicle interior (S15: YES), the control unit 4 outputs a notification command signal from the HMI control unit 11 to the notification unit 26, and the calculated charging schedule is notified to the notification unit 26. (S19, fourth procedure). Also in this case, when the control unit 4 displays a charging schedule notification screen similar to the charging schedule notification screen 41 displayed on the mobile terminal 3 and determines that the user has operated the confirm button (S20: YES), the calculation is performed. The charging schedule is determined (S18), the charging schedule determination process is terminated, and the process returns.

  In the above description, the configuration in which the charging schedule notification screen is switched between the vehicle side device 2 and the portable terminal 3 according to whether or not the user is staying in the vehicle interior has been described. The charging schedule notification screen may be displayed by the vehicle side device 2 or the portable terminal 3 that has been placed. In other words, the user may input the set time, the set charge amount, or the set item on either the vehicle-side device 2 or the mobile terminal 3, or may check the charge schedule. If the user is away from home or at home, the mobile terminal 3 may be operated to input a set time, a set charge amount, or a set item, or a charge schedule displayed on the mobile terminal 3 may be confirmed. . If the user is in the vehicle interior, the vehicle side device 2 may be operated to input the set time, the set charge amount, or the set item, or the charge schedule displayed on the vehicle side device 2 may be confirmed. good.

(2) Operation Control Process When the operation control process is started, the control unit 4 determines whether or not it is time to start or end charging by the charging units 5 to 7 (S21 to S26). If the control unit 4 determines that it is not at any timing (all of S21 to S26: NO), it ends the operation control process, returns, and waits for the next start timing of the operation control process. When it is determined that it is time to start any of the charging (any of S21 to S23: YES), the control unit 4 outputs a charging start command to the corresponding charging unit to start charging (S27 to S29, Fifth procedure). When the control unit 4 determines that it is time to end any of the charging (any of S24 to S26: YES), the control unit 4 outputs a charging end command to the corresponding charging unit to end the charging (S30 to S30). S32, fifth procedure).

  In the example of FIG. 6, at the time (t0), the control unit 4 outputs a charging start command to the plug-in charging unit 5 to start charging by the plug-in charging method, and sends the charging start command to the solar charging unit 7. To start charging using the solar charging method. Next, at time (t1), the control unit 4 outputs a charging end command to the plug-in charging unit 5 to end charging by the plug-in charging method, and outputs a charging start command to the non-contact charging unit 6. Start charging using the non-contact charging method. Next, at the time (t2), the control unit 4 outputs a charging end command to the non-contact charging unit 6 to end the charging by the non-contact charging method. Then, when the time (t3) comes (when the set time is reached), the control unit 4 outputs a charge end command to the solar charging unit 7 to end the charging by the solar charging method.

  In the example of FIG. 6, each charging unit 5 to 7 is operable, the vehicle is parked outdoors, and solar radiation can be expected. However, the solar charging unit 7 is operable. For example, if the vehicle is parked indoors (where sunlight cannot be received) or if sunlight cannot be expected due to rain, plug-in charging is not used except for solar charging. The charging schedule using charging by the system and charging by the non-contact charging system is determined. In the example of FIG. 6, the case where the charge priority is set is described. However, if the time priority is set, the charging schedule is set without considering the time (t1) when the power charge changes. Will be determined.

  In addition, during charging according to the charging schedule determined as described above, the control unit 4 periodically transmits, for example, a charging notification signal from the wireless communication unit 10 to the mobile terminal 3 via the communication network. When the portable terminal 3 receives the charging notification signal transmitted from the vehicle-side device 2 in this manner, the portable terminal 3 notifies the progress of charging included in the charging notification signal by the notification unit 28. That is, the portable terminal 3 displays a charging notification screen 51 as shown in FIG. On the charging notification screen 51, an image 52 indicating the flow of power and an index 53 indicating the progress of each charging by the charging units 5 to 7 are displayed. In the image 52, for example, when charging by a plug-in charging method is in progress, the charging path 52a (PLUG) for plug-in charging is displayed blinking to notify that charging is in progress. The same applies to the charging path 52b (WIRELESS) for contactless charging and the charging path 52c (SOLAR) for solar charging.

  The mobile terminal 3 may display any setting input screen, and may display the setting input screen 61 shown in FIG. 9 instead of the setting input screen 31 shown in FIG. On the setting input screen 61, a plug-in charging time setting area 62, a non-contact charging time setting area 63, a solar charging time setting area 64, and an entire charging time display area 65 are displayed. In this case, the user individually inputs the charging time for each charging method. That is, the user operates the up key 62a and the down key 62b in the plug-in charging time setting area 62 to input the charging time by the plug-in charging method, and the up key 63a and the down key 63b in the non-contact charging time setting area 63. To input the charging time by the non-contact charging method, and input the charging time by the solar charging method by operating the up key 64a and the down key 64b of the solar charging time setting area 64. The control unit 4 calculates the total charging time on the assumption that the operations of the charging units 5 to 7 are controlled according to the charging time input by these users. In this case, the control unit 4 calculates a time shorter than the total charging time by each charging method as the total charging time. In the example of FIG. 9, the user inputs “1 hour” as the charging time by the plug-in charging method, inputs “2 hours” as the charging time by the non-contact charging method, and “3” as the charging time by the solar charging method. "Time" is entered, and "4 hours" is calculated as the total charging time.

  Further, the mobile terminal 3 may display any charging schedule notification screen, and may display a charging schedule notification screen 71 shown in FIG. 10 instead of the charging schedule notification screen 41 shown in FIG. On the charging schedule notification screen 71, a plug-in charging button 72, a non-contact charging button 73, a solar charging button 74, an overall charging button 75, an individual charging amount display area 76, and a total charging amount display area 77 are displayed. In this case, when the user operates the plug-in charging button 72, the mobile terminal 3 charges the amount of charging by the plug-in charging method from the time point (for example, 15 minutes before in FIG. 10) retroactive by a predetermined period from the current time point to the current time point. In the individual charge amount display area 76. Similarly, when the user operates the non-contact charge button 73, the mobile terminal 3 displays the transition of the charge amount according to the non-contact charge method from the time point that is back by a predetermined period with respect to the current time to the current time point as an individual charge amount display area 76. To display. When the user operates the solar charge button 74, the mobile terminal 3 displays a change in the charge amount according to the solar charge method from the time point that is traced back for a predetermined period with respect to the present time to the individual charge amount display area 76. Further, the mobile terminal 3 displays in the total charge amount display area 77 the transition of the total charge amount from the time point that is traced back for a predetermined period on the basis of the present time.

As described above, according to the present embodiment, the following operational effects can be obtained.
In a configuration in which the battery 19 is charged by a plug-in charging method, a non-contact charging method, or a solar charging method, when the user inputs a set time or a set charge amount, the charge amount of the battery 19 becomes the set charge amount at the set time. The charging schedule which shows each operation | movement of each charging part 5-7 is determined. And the determined charging schedule is alert | reported as charging information, and each operation | movement of the plug-in charging part 5, the non-contact charging part 6, and the solar charging part 7 is controlled according to the determined charging schedule. Thereby, the information regarding the charge by each charge system can be reported appropriately, and convenience can be improved.

  In addition, when setting items such as charge priority and time priority are set, the charging schedule is determined in consideration of the setting items, so the plug-in charging unit 5 and non-contact charging are focused on the charge and time. Each operation of the unit 6 and the solar charging unit 7 can be controlled. In addition, since the user can set the set time, the set charge amount, and the like by operating the mobile terminal 3, the charge schedule can be determined and confirmed remotely without being in the passenger compartment. Further, since the user can operate the vehicle side device 2 to set the set time, the set charge amount, etc., for example, before getting off, the charge schedule can be determined and confirmed for the next boarding. In addition, the transition of each charge amount according to each charge method, the classification of each charge amount according to each charge method, and the distinction between the charge amount due to fossil energy and the charge amount due to non-fossil energy are reported in an identifiable manner. Various information can be confirmed by the user.
