(Background to inventing one aspect of the present disclosure)
First, an aspect of one aspect according to the present disclosure will be described.

  Patent Document 1 discloses a technique for outputting information related to a parking fee to a portable information device carried by the user using the parking start time, the unit time fee of the parking lot, and the current time. As the information related to the parking fee, a map including the current position of the user and the route to the parking lot, the current parking fee and the remaining time are displayed on the display device of the portable information device (FIG. 1). 13).

  Thus, in Patent Document 1, it is possible to know the remaining time during which the current parking fee is continued. However, Patent Document 1 does not notify the user of the time to depart from the current position toward the parking lot in time for the current parking fee.

  Patent Document 2 calculates the position difference time between the position of the mobile terminal held by the user and the parking position of the vehicle, and when the calculated position difference time is shorter than the time until the next charge addition, the time until the charge addition is calculated, When the position difference time is longer than the time until the next fee addition, a technology is disclosed in which information on the fee addition at the time of the fee addition is transmitted to each mobile terminal.

  The timing to transmit to this portable terminal is a timing that is in time for the charge addition time with some margin (see [0010] of Patent Document 2). Therefore, in Patent Literature 2, unlike Patent Literature 1, it is possible to determine at which timing to return to the vehicle (see [0011] in Patent Literature 2).

  For example, when the destination is a large shopping center, it may take a relatively long time for the user to settle a large amount of shopping. In such a case, there is a user's request to know in advance the time to depart from the current position toward the parking lot. However, Patent Documents 1 and 2 cannot meet such a user's request.

  Further, in Patent Document 2, the position difference time is calculated by dividing the distance between the portable terminal and the parking position by the average walking speed of a normal person (see [0010] of Patent Document 2). ). Therefore, in the case of being unable to move at an average walking speed due to the degree of congestion or the weather, in Patent Document 2, it is difficult to calculate an accurate time.

  In order to solve the above problems, the present inventor has come up with the invention according to the following aspects.

One aspect of the present disclosure is:
An information notification method in an information notification system comprising: a navigation system mounted on a vehicle for guiding a destination and a parking lot to a user; and the user's portable device capable of communicating with the navigation system,
A first acquisition step of acquiring a parking available time during which parking can be continued in the parking lot;
A measuring step for measuring a moving time when the user moves from the parking lot to the destination;
A second acquisition step of acquiring a round trip time required for the user to make a round trip from the destination to the parking lot based on the travel time;
Subtracting the round trip time and the elapsed time from the time when the user arrived at the destination from the available parking time, a time calculation step for calculating the remaining time that the user can stay at the destination;
A determination step of determining whether or not the remaining time is equal to or less than a threshold value set in advance to a value exceeding zero;
A notification step for notifying the user that the remaining time is small when it is determined in the determining step that the remaining time is equal to or less than the threshold;
Is provided.

  In this aspect, when it is determined that the remaining time is equal to or less than the threshold, the user is notified that the remaining time is equal to or less than the threshold. The threshold value is set in advance to a value exceeding zero. For this reason, according to this aspect, it is possible to notify the user in advance until the remaining time becomes zero and the time to leave the destination is reached. Therefore, the user can make preparations for leaving the destination.

In the above aspect, for example,
In the second acquisition step, a value obtained by doubling the travel time measured in the measurement step may be acquired as the round trip time.

  In this aspect, what doubled the movement time when the user moved from the parking lot to the destination is acquired as the round-trip time required to make a round-trip from the destination to the parking lot. That is, twice the travel time when the user actually travels is used as the round trip time for calculating the stayable time. Therefore, according to this aspect, since the travel time of the user himself / herself is used, the stayable time can be calculated with high accuracy.

In the above aspect, for example,
The information notification system further includes a measurement history storage unit that stores a measurement time measured when at least one of the user and a person different from the user moves from the destination to the parking lot,
In the second acquisition step, a value obtained by adding the travel time and the measurement time stored in the measurement history storage unit may be acquired as the round trip time.

  In this aspect, at least one of the user and a person different from the user actually adds the measurement time measured when moving from the destination to the parking lot, and the movement time, from the destination to the parking lot. Acquired as the round-trip time required for reciprocal movement. For this reason, according to this aspect, the travel time when at least one of the user and the person different from the user actually travels is used to calculate the stayable time. Accordingly, since the actual travel time is used, the stayable time can be calculated with high accuracy.

In the above aspect, for example,
A third acquisition step of acquiring environmental information indicating a surrounding state when the user is moving from the parking lot to the destination;
In the measurement history storage unit, the environmental information when the measurement time is obtained is stored in association with the measurement time,
In the second acquisition step, the round trip time is obtained by adding the travel time and the measurement time stored in the measurement history storage unit in association with the environment information acquired in the third acquisition step. May be obtained as

  In this aspect, environmental information indicating the surrounding state when the user is moving from the parking lot to the destination is acquired. Environmental information when the measurement time is obtained is stored in the measurement history storage unit in association with the measurement time. A round trip time is obtained by adding the measurement time stored in the measurement history storage unit in association with the environmental information when the user is moving from the parking lot to the destination and the movement time.

  For this reason, according to this aspect, the travel time and the measurement time having the same environmental information are used for calculating the stayable time. Accordingly, since the environmental information is the same, the stayable time can be calculated with high accuracy.

In the above aspect, for example,
A speed calculating step of calculating a moving speed when the user is moving from the parking lot to the destination;
In the measurement history storage unit, the moving speed of the person when the measurement time is obtained is stored in association with the measurement time,
In the second acquisition step, the round trip time is obtained by adding the travel time and the measurement time stored in the measurement history storage unit in association with the travel speed calculated in the speed calculation step. May be acquired.

  In this aspect, the moving speed when the user is moving from the parking lot to the destination is calculated. The movement speed of the person when the measurement time is obtained is stored in the measurement history storage unit in association with the measurement time. The round trip time is obtained by adding the measurement time stored in the measurement history storage unit in association with the movement speed when the user is moving from the parking lot to the destination and the movement time. For this reason, according to this aspect, the measurement time with the same moving speed is used for calculation of the stayable time. Therefore, since the moving speed is the same, the stayable time can be calculated with high accuracy.

In the above aspect, for example,
A fourth acquisition step of acquiring attribute information representing the attribute of the parking lot;
In the determination step, the determination is performed using only the first predetermined value as the threshold, or the determination is performed using a second predetermined value different from the first predetermined value and the first predetermined value as the threshold. Determining step based on the attribute information acquired in the fourth acquisition step;
Further comprising
In the determination step, the determination may be performed using the threshold value determined in the determination step.

  In this aspect, attribute information representing the parking lot attribute is acquired. Based on the attribute information, whether the determination is performed using only the first predetermined value as the threshold or whether the determination is performed using the second predetermined value and the first predetermined value different from the first predetermined value as the threshold. It is determined. In the determination step, determination is performed using the determined threshold value. For this reason, according to this aspect, the prior notification with respect to a user is performed in multiple times by the attribute of a parking lot. Therefore, the advance notification of the number of times according to the attribute of the parking lot can be made to the user.

In the above aspect, for example,
In the determining step, when only the first predetermined value is used as the threshold in the determining step, the user is notified using the first device, and the first predetermined value and the second are used as the threshold. When a predetermined value is used, the user may be notified using a second device different from the first device.

  In this aspect, when only the first predetermined value is used as the threshold value in the determination step, the user is notified using the first device, and the first predetermined value and the second predetermined value are used as the threshold values. Is notified to the user using a second device different from the first device. That is, different devices are used for notification depending on whether the prior notification to the user is performed only once or twice. For this reason, according to this aspect, for example, when a device having lower power consumption than the first device is used as the second device, it is possible to suppress an excessive increase in power consumption by performing the prior notification twice.

(Embodiment)
Hereinafter, some embodiments of the present disclosure will be described with reference to the drawings. In the drawings, the same reference numerals are used for the same components.

(First embodiment)
FIG. 1 is a block diagram illustrating a configuration of an information notification system 1 according to the first embodiment. FIG. 2 is a diagram schematically illustrating a situation in which the information notification system according to the first embodiment and each embodiment described later is used.

  As shown in FIG. 1, the information notification system 1 of the first embodiment includes a mobile device 100 and a navigation system 210 mounted on a car 200. The mobile device 100 includes a communication unit 101, a navigation unit 102, a dialogue processing unit 103, a measurement start determination unit 104, a remaining time measurement unit 105, a return notification unit 106, a clock unit 107, a display 108, a speaker 109, a microphone 110, and a vibration. Part 111 is provided. The navigation system 210 mounted on the car 200 includes a measurement history storage unit 211.

  As shown in FIG. 2, the user 11 of the portable device 100 and the car 200 parks the car 200 in the parking lot 13 near the destination 12. The available days of the parking lot 13 are Monday through Saturday, and the available time zone is from 8 am to 6 pm. Moreover, in this parking lot 13, parking available time is restrict | limited to 2 hours and it is prohibited to return within 1 hour after leaving a parking lot.

  For the user 11 getting out of the car 200, the portable device 100 displays a map on the display 108, for example, and guides the route to the destination 12. The user 11 arriving at the destination 12 performs shopping, for example. When the remaining remaining time at the destination 12 reaches a predetermined threshold value (for example, 10 minutes in the first embodiment), the portable device 100 displays, for example, “10 minutes left” on the display 108. Thus, the user 11 is notified in advance that the remaining time available for staying has decreased. In addition, it is not limited to notifying the specific remaining time of “there are 10 minutes”. For example, a prior notification that “the remaining time has decreased” may be used.

  When the remaining time remaining at the destination 12 becomes zero, the mobile device 100 displays, for example, “Let's go back” on the display 108 and leaves the user 11 toward the parking lot 13. Prompt. For the user 11 who leaves the destination 12, the mobile device 100 displays a map on the display 108, for example, and guides the route to the parking lot 13.

  The mobile device 100 is, for example, a wearable terminal such as a wristwatch, glasses, or smart key that can be worn by the user 11. In addition, the portable device 100 of 1st Embodiment is not restricted to a wearable terminal, For example, a smart phone or a mobile telephone etc. may be sufficient. Alternatively, the mobile device 100 may be a tablet computer. The mobile device 100 of the first embodiment may be any device that can be carried by the user 11.

  Returning to FIG. 1, when the destination is set by the user 11, the navigation system 210 is a known system that guides the route to the destination and searches for and guides the parking lot around the destination. The navigation system 210 holds attribute information indicating the attribute of the searched parking lot. The parking lot attribute information includes a parking available time during which parking can be continued. The measurement history storage unit 211 included in the navigation system 210 will be described later.

  The communication unit 101 of the portable device 100 performs near field communication with the navigation system 210. The communication unit 101 may be based on a wireless LAN standard, for example. The communication unit 101 may be compliant with various wireless LAN methods, for example, a method using 2.4 GHz band radio waves. The communication unit 101 only needs to be capable of performing short-range wireless communication with the navigation system 210.

  The clock unit 107 has a clock function for acquiring the current time. The clock unit 107 has a function of counting elapsed time. In the first embodiment, the display 108 includes, for example, a liquid crystal panel. The display 108 is not limited to the liquid crystal method, and may be another display method such as an organic EL method. The vibration unit 111 includes, for example, a motor, and urges the user 11 to pay attention by vibrating the motor by rotation.

  The navigation unit 102 has a GPS (Global Positioning System) function, a map display function, a current position display function, a destination display function, a distance calculation function between the current position and the destination, and the like. That is, the navigation unit 102 has the same function as the navigation system 210. When the car 200 is parked in the parking lot 13, the navigation system 210 transmits setting information such as a parking available time that can be continuously parked at the parking lot 13, the destination 12, and the parking lot 13 to the communication unit 101. The navigation unit 102 takes over guidance of the destination 12 for the user 11 and the like.

  FIG. 3 is a diagram showing a guidance screen 30 displayed on the display 108 of the mobile device 100 as an example of a graphical user interface. The guidance screen 30 includes a map display area 31 and a message display area 32. In the map display area 31, the user 11 and the destination 12 are shown on the surrounding map. In the message display area 32, for example, a message for guidance to the user 11 such as “straight to the destination” is displayed.

  The navigation unit 102 displays the guidance screen 30 shown in FIG. 3 on the display 108 based on the setting information taken over from the navigation system 210 and guides the user 11 to the destination 12.

  Returning to FIG. 1, the microphone 110 collects the user's voice and generates an analog voice signal. The microphone 110 converts the generated analog audio signal into digital data, and generates a digital audio signal. The microphone 110 outputs the generated digital audio signal to the dialogue processing unit 103.

  The dialogue processing unit 103 has a voice recognition function and a voice synthesis function. The dialogue processing unit 103 includes an acoustic model and a language model for speech recognition. The dialogue processing unit 103 includes a scenario that defines the content of response to the generated voice. The dialogue processing unit 103 recognizes the voice generated based on the voice signal input from the microphone 110, synthesizes the voice for response according to the scenario, and outputs the synthesized voice from the speaker 109.

  The measurement start determination unit 104 determines whether to start measuring elapsed time. For example, when the user 11 stops the engine of the car 200 in the parking lot 13, or when the user 11 gets out of the car 200 and locks the door in the parking lot 13, the measurement start determination unit 104 moves the user 11 to the portable device 100. On the other hand, when a predetermined operation is performed, or when the user 11 instructs the start of measurement by voice through the microphone 110, it may be determined that the measurement of the elapsed time is started.

  Alternatively, when the measurement start determination unit 104 detects that the car 200 has arrived at the parking lot 13 by the GPS function of the navigation unit 102, the measurement start determination unit 104 communicates between the communication unit 101 and the gate of the parking lot 13. When it is detected that the gate of the parking lot 13 has been passed or the ticket of the parking lot 13 has been acquired, it may be determined that the measurement of the elapsed time is started.

  When the measurement start determination unit 104 determines that the remaining time measurement unit 105 starts to measure the elapsed time, the remaining time measurement unit 105 uses the clock unit 107 to measure the elapsed time. The remaining time measuring unit 105 measures a moving time Tm required for the user 11 to move from the parking lot 13 to the destination 12 (an example of a measuring unit). The remaining time measuring unit 105 acquires a value obtained by doubling the measured moving time Tm as a reciprocating time required for the user 11 to reciprocate from the destination 12 to the parking lot 13 (an example of a second acquiring unit). The remaining time measurement unit 105 (an example of a first acquisition unit) acquires from the navigation unit 102 a parking available time during which the car 200 can be parked in the parking lot 13.

The remaining time measuring unit 105 (an example of a time calculating unit) calculates the remaining time Tr that the user 11 can stay at the destination 12 using the following equation (1).
Tr = Tp−Tm × 2−Ts (1)
Here, Tp is a parking available time (in this first embodiment, Tp = 120 minutes as shown in FIG. 2), and Ts is an elapsed time from when the user 11 arrives at the destination 12.

  In the first embodiment, as described above, the time required for the user 11 to reciprocate from the destination 12 to the parking lot 13 is doubled as the travel time Tm. In other words, the time required for the user 11 to move from the destination 12 to the parking lot 13 is considered to be equal to the movement time Tm actually required for the user 11 to move from the parking lot 13 to the destination 12. Yes.

  The remaining time measuring unit 105 (an example of a determining unit) determines whether or not the remaining time Tr has reached a predetermined threshold Tth (for example, Tth = 10 minutes in the first embodiment). Further, the remaining time measuring unit 105 determines whether or not the remaining time Tr has become zero.

  When the remaining time measurement unit 105 determines that the remaining time Tr has reached the threshold value Tth, the return notification unit 106 (an example of a notification unit) notifies the user 11 that the remaining time Tr has reached the threshold value Tth. I do. The return notification unit 106 prompts the user 11 to prepare for departure from the destination 12 by this advance notification.

  When the remaining time measuring unit 105 determines that the remaining time Tr has become zero, the return notification unit 106 notifies the user 11 that the remaining time Tr has become zero. With this notification, the return notification unit 106 prompts the user 11 to leave the destination 12 toward the parking lot 13.

  4 and 5 are diagrams each showing a notification screen 40 displayed on the display 108 of the mobile device 100 as an example of a graphical user interface. The notification screen 40 includes a map display area 41 and a message display area 42. In the map display area 41, the user 11 and the destination 12 are shown superimposed on the surrounding map. This indicates that the user 11 is staying at the destination 12.

  In the message display area 42 of FIG. 4, a prior notice message is displayed to the user 11 that “the remaining time for staying is 10 minutes”. It should be noted that the specific remaining time is not limited to being displayed as “the remaining time that can be stayed is 10 minutes”. For example, a message “Remaining time has decreased” may be displayed in the message display area 42.

  Further, in the message display area 42 of FIG. 5, a message for prompting the user 11 “It is time to return” to leave the destination 12 and go to the parking lot 13 is displayed.

  In FIG. 5, the device used for notifying the user 11 that the remaining time has become zero is not limited to the display 108. In FIG. 5, the speaker 109 is used in the notification 51 by the sound “beep”, the notification 52 by the music, and the notification 53 by the voice “let's go back”. In addition, the vibration unit 111 is used in the notification 54 by the vibration “Bull Bull”.

  The notifications 51 to 54 are shown only in FIG. 5, but the notifications 51 to 54 may be performed using the speaker 109 or the vibration unit 111 even in the prior notification of FIG. 4. In the notification to the user 11 shown in FIGS. 4 and 5, at least one of notifications using the display 108, the speaker 109, and the vibration unit 111 may be employed. In addition to the notifications shown in FIGS. 4 and 5, for example, the display on the display 108 may blink.

  In FIG. 5, when adopting the voice notification 53 of “Let's go back,” as the notification method for notifying the user 11 that the remaining time has become zero, the return notification unit 106 displays the remaining time. When the remaining time Tr calculated by the measuring unit 105 becomes zero, the dialogue processing unit 103 is instructed to notify that the remaining time Tr has become zero. In response to the instruction, the dialogue processing unit 103 causes the speaker 109 to output a voice saying “Let's go back.”

  FIG. 6 is a sequence diagram schematically showing the operation of the information notification system 1 of the first embodiment shown in FIG. The operation of FIG. 6 is started when the user 11 leaves the home with the car 200.

  First, the user 11 operates the navigation system 210 to set the destination 12 (S601). In response to the setting of the destination 12, the navigation system 210 searches for the position of the destination 12 (S602). Next, the navigation system 210 searches for a parking lot near the destination 12 and presents it to the user 11 (S603).

  The user 11 selects the parking lot 13 from the presented parking lots (S604). The navigation system 210 guides the selected parking lot 13 (S605). The navigation system 210 detects that the car 200 has arrived at the parking lot 13 by using, for example, a GPS function (S606).

  Next, the navigation system 210 transmits the information about the destination 12 such as the position of the destination 12 and the attribute information of the parking lot 13 such as the parking available time to the communication unit 101 of the portable device 100 (S607, first acquisition). Example of step).

  The portable device 100 executes guidance and notification processing for the user 11 using the information transmitted from the navigation system 210 (S608). This guidance and notification process will be described in detail later with reference to FIG.

  When the guidance and notification process of S608 ends, the navigation unit 102 of the mobile device 100 guides the parking lot 13 to the user 11 (S609). The navigation unit 102 detects that the user 11 has arrived at the parking lot 13 by the GPS function (S610). Note that the mobile device 100 measures the time required for the user 11 to move from the destination 12 to the parking lot 13.

  When the user 11 arrives at the parking lot 13, the communication unit 101 of the portable device 100 transmits the measurement time measured for the user 11 to move from the destination 12 to the parking lot 13 to the navigation system 210 (S611). ).

  The navigation system 210 stores the measurement time transmitted from the mobile device 100 in the measurement history storage unit 211 (S612), and the process of FIG. 6 ends. In this way, by storing the measurement time transmitted from the portable device 100 in the measurement history storage unit 211, the next time the user 11 parks the car 200 in the parking lot 13 and goes to the destination 12, the measurement is performed. The measurement time saved in the history storage unit 211 can be used.

  In S611, the communication unit 101 of the portable device 100 further displays the travel time required for the user 11 to travel from the parking lot 13 to the destination 12 and the stay time during which the user 11 stayed at the destination 12 in the navigation system. You may transmit to 210. The navigation system 210 may store these transmitted times in the measurement history storage unit 211 in S612.

  FIG. 7 is a flowchart schematically showing a procedure of guidance and notification processing (S608 in FIG. 6) executed in the mobile device 100. The processing in FIG. 7 is started when the measurement start determination unit 104 determines to start measuring elapsed time.

  First, the remaining time measuring unit 105 starts measuring elapsed time using the clock unit 107 (S701). Next, the navigation unit 102 guides the destination 12 to the user 11 as described with reference to FIG. 3 (S702). The navigation unit 102 determines whether or not the user 11 has arrived at the destination 12 (S703).

(Modification of the fourth embodiment)
(1) In the operation of FIG. 14, in S1001, the time required for the user 11 to move from the destination 12 to the parking lot 13 is the same as that in the first embodiment. The remaining time Tr is calculated on the assumption that it is equal to the movement time Tm actually required for the movement. That is, the remaining time measuring unit 105 calculates the remaining time Tr using the above equation (1). However, the fourth embodiment is not limited to this.

  FIG. 15 is a diagram illustrating an example of a data structure of history information 1500 stored in the measurement history storage unit 402 in S1201 of FIG. The history information 1500 stored in the measurement history storage unit 402 will be described with reference to FIGS.

  As illustrated in FIG. 15, the history information 1500 includes a day of the week 1501, a time zone 1502, weather 1503, a movement speed 1504, and a movement time 1505.

  In FIG. 13, the moving speed calculation unit 411 of the cloud server 400 calculates the moving speed of the user heading from the destination to the parking lot based on the information from the navigation unit 102. The movement speed calculation unit 411 stores the calculated movement speed 1504 in the measurement history storage unit 402 as history information 1500 in association with the measured movement time 1505.

  The mobile device 100 or the mobile device 300 may be equipped with a GPS function. The mobile device 100 or the mobile device 300 may transmit the location information of the user 11 detected by the GPS function to the cloud server 400. The moving speed calculation unit 411 is based on the elapsed time obtained from the clock unit 107 and the moving distance obtained from the user's position information transmitted from the mobile device 100 or the mobile device 300, from the destination to the parking lot. The moving speed may be calculated.

  The environment information acquisition unit 412 acquires the current date and time from the clock unit 107 when S1201 in FIG. 14 is executed (an example of a third acquisition step). The environment information acquisition unit 412 extracts the day of the week and the time zone from the acquired date and time. The environment information acquisition unit 412 stores the extracted day 1501 and time zone 1502 in the measurement history storage unit 402 as history information 1500 in association with the measured travel time 1505.

  When S1201 in FIG. 14 is executed, the environment information acquisition unit 412 further acquires information regarding the weather around the destination via, for example, the Internet. The environment information acquisition unit 412 stores the weather 1503 obtained from the acquired weather information in the measurement history storage unit 402 as history information 1500 in association with the measured travel time 1505.

  The measurement history storage unit 402 stores a plurality of user history information 1500 as shown in FIG. 15 for each combination of destination and parking lot.

  The moving speed calculation unit 411 uses the GPS function of the mobile device 100 or the mobile device 300 when the user 11 is moving from the parking lot 13 to the destination 12, for example, the distance that the user 11 moves for one minute From this, the moving speed of the user 11 is calculated (an example of a speed calculating step). The environment information acquisition unit 412 acquires the current day of the week and time zone using the information of the clock unit 107 when the user 11 is moving from the parking lot 13 to the destination 12, and for example via the Internet. To obtain information about the current weather.

  The measurement history search unit 413 searches the measurement history storage unit 402 for history information 1500 corresponding to the combination of the destination 12 and the parking lot 13 where the user 11 is currently moving. The measurement history search unit 413 extracts the travel time associated with the travel speed, the current weather, the current day of the week, and the time zone of the user 11 from the retrieved history information 1500.

The remaining time measuring unit 105 calculates the remaining time Tr that the user 11 can stay at the destination 12 using the following equation (2).
Tr = Tp− (Tm + Th) −Ts (2)
Here, Th is the travel time extracted by the measurement history search unit 413.

  In the modification of the fourth embodiment, as can be seen from the above equation (2), the movement actually required when the user 11 moved in the same weather, the same day of the week, and the same time zone as the user 11 in the past. The sum of the time Th and the travel time Tm is the round-trip time required to travel back and forth from the destination 12 to the parking lot 13.

  If it is the same day of the week and the same time zone, the degree of congestion on the route from the destination 12 to the parking lot 13 is similar. In addition, if the weather is the same, the degree of difficulty in movement is similar, so it can be considered that it can move at the same movement speed. Therefore, according to the modification of the fourth embodiment, the remaining time Tr can be calculated with high accuracy.

  In the operation of FIG. 14, the remaining time measuring unit 105 calculates the remaining time Tr using the above equation (1). In this case, the cloud server 400 according to the fourth embodiment may not include the movement speed calculation unit 411, the environment information acquisition unit 412, and the measurement history search unit 413.

  (2) In the operation of FIG. 14, prior notification is performed in S1002 when the remaining time Tr reaches the threshold Tth, as in the first embodiment. That is, the prior notification until the remaining time Tr becomes zero is performed only once. However, the fourth embodiment is not limited to this.

  In FIG. 13, the navigation system 210 holds parking lot attribute information as in the first embodiment. This attribute information of the parking lot includes information on whether or not it will violate the regulations when the parking time in the parking lot exceeds the parking available time Tp. The navigation unit 102 of the cloud server 400 holds the parking lot attribute information transmitted from the navigation system 210.

  The parking lot determination unit 414 of the cloud server 400 acquires parking lot attribute information from the navigation unit 102 (an example of a fourth acquisition step). Based on the acquired attribute information, the parking lot determination unit 414 determines whether or not the law is violated when the parking time in the parking lot 13 exceeds the parking available time Tp.

  For example, in the case of Japan, the parking lot determination unit 414 determines whether or not the parking lot 13 is a parking space provided on the side of the road and provided with a parking meter. Alternatively, the parking lot determination unit 414 determines whether the parking lot 13 is a public parking lot, for example, in the UK. In these parking spaces and public parking lots, if the parking time exceeds the available parking time, the law will be violated.

  The notification frequency determination unit 415 determines the frequency (number of times) of prior notification of the remaining time Tr executed by the return notification unit 106 based on the determination result of the parking lot determination unit 414 (an example of a determination step). If the parking lot determination unit 414 determines that the parking time exceeds the available parking time Tp, the notification frequency determination unit 415 increases the frequency of prior notification.

  The notification frequency determination unit 415, for example, when the remaining time Tr reaches the first threshold Tth1 (for example, Tth1 = 10 minutes) and the remaining time Tr is the second threshold Tth2 (Tth2> Tth1, for example, Tth2 = 20 minutes). ) Is determined to be notified to the user 11 twice. The number of prior notifications is not limited to two. The notification frequency determination unit 415 may determine that three or more thresholds are provided and the prior notification is performed three or more times.

  The return notification unit 106 instructs the return output unit 122 of the mobile device 100 to perform advance notification to the user 11 the number of times determined by the notification frequency determination unit 415. As described above, according to the modification of the fourth embodiment, by increasing the frequency of prior notification to the user 11, it is possible to urge the user 11 to pay attention a plurality of times so as not to violate the law.

  In addition, when the remaining time Tr reaches the first threshold value Tth1 and when the remaining time Tr reaches the second threshold value Tth2, the return notification unit, as illustrated in FIG. 4 of the first embodiment, Similarly to when Tr reaches the threshold value Tth, the notification screen 40 is displayed on the display 108 (an example of the first device), and the return output unit 122 is instructed to notify the user 11 in advance. Good.

  Alternatively, the return notification unit 106 returns to notify the user 11 without using the display 108 when the remaining time Tr reaches the first threshold Tth1 and when the remaining time Tr reaches the second threshold Tth2. The output unit 122 may be instructed. Specifically, the return notification unit 106 uses a notification method other than the display 108 shown in FIG. 5, that is, a sound notification 51 using a speaker 109 (an example of a second device), a music notification 52, and a voice notification. 53 and the notification 54 using the vibration unit 111 (an example of the second device), the return output unit 122 may be instructed to notify the user 11 in advance using at least one notification method. .

  When the advance notification frequency for the user 11 is increased, if all the prior notifications are given by the display 108, the power consumption is greatly increased. For this reason, the battery that is the power source of the mobile device 100 is consumed very much, and charging is required in a short time.

  On the other hand, it is possible to suppress an excessive increase in power consumption by notifying the user 11 using the speaker 109 or the vibration unit 111 without using the display 108. As a result, it is possible to prevent the battery that is the power source of the mobile device 100 from being excessively consumed.

  In the operation of FIG. 14, prior notification is performed in S1002 when the remaining time Tr reaches the threshold value Tth, as in the first embodiment. That is, the prior notification until the remaining time Tr becomes zero is performed only once. In this case, the cloud server 400 of the fourth embodiment may not include the parking lot determination unit 414 and the notification frequency determination unit 415.
