[overall structure]
FIG. 1 shows a front view of a terminal device 100 to which an information providing device according to the present invention is applied. The terminal device 100 is a portable terminal that can be carried by a user, and includes a display 110 on which a touch panel 120 is stacked. The terminal device 100 provides route guidance to designated destinations for pedestrians, vehicles, and the like.

FIG. 2 shows a schematic configuration of the terminal device 100. As shown in FIG. 2, the terminal device 100 includes an output section 11, an input section 12, a storage section 13, a communication section 14, a camera 15, a GPS receiver 16, and a control section 17. Each element of the terminal device 100 is interconnected via a bus 10, and is configured such that necessary information can be transmitted between each element.

The output unit 11 includes a display 110, a speaker 111 that outputs audio, and the like, and outputs information in response to operations by the user of the terminal device 100 under the control of the control unit 17. The input unit 12 includes a touch panel 120 and is an interface that receives necessary commands and information input, that is, operations, performed by a terminal user on the terminal device 100. For example, the input unit 12 accepts inputs specifying a destination, inputs specifying route search conditions, and the like. In addition to the touch panel 120, the input unit 12 may include keys, switches, buttons, voice input devices, etc. for inputting various commands and data.

The storage unit 13 stores programs for controlling the operation of the terminal device 100 and holds information necessary for the operation of the terminal device 100. For example, the storage unit 13 stores various data used for navigation processing, such as map data. The map data includes road data represented by links corresponding to roads and nodes corresponding to road connecting parts (intersections), service areas and parking areas (these are also collectively referred to as "SA/PA"). ), etc. Contains facility information regarding each facility. Furthermore, the storage unit 13 stores link ID indicating the main line of the expressway in association with information on SA/PA where the user can stop by. SA/PA is an example of a "rest facility" in the present invention.

The communication unit 14 transmits and receives data to and from other devices according to a predetermined protocol. The camera 15 generates a photographed image under the control of the control section 17 and transmits it to the control section 17 . The GPS receiver 16 generates information on the current position of the terminal device 100 by receiving radio waves carrying downlink data including positioning data from a plurality of GPS satellites, and transmits the information to the control unit 17 .

The control unit 17 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc. (not shown), and performs various controls on each component within the terminal device 100.

For example, the control unit 17 receives an input designating a destination through the input unit 12, sets a route (also referred to as a "guide route") to the designated destination, and displays the guide route on a map around the current location. Display. Further, the control unit 17 displays an image (also referred to as a "guidance image Im") that guides the facilities within the SA/PA while driving on the expressway. Further, the control unit 17 measures the continuous driving time of the vehicle Ve, and provides voice guidance to the driver to urge the driver to take a break according to the continuous driving time.

The control unit 17 is an example of an "obtaining unit", a "providing unit", and a computer that operates based on a program in the present invention. Furthermore, the content of the audio urging the user to take a break that the control unit 17 outputs from the speaker 111 is an example of "rest information" in the present invention.

[How to execute break guidance]
Next, a method of executing the break guidance executed by the control unit 17 will be described. Roughly speaking, the control unit 17 flexibly changes the continuous driving time (also referred to as "rest threshold Tth") of the vehicle Ve that provides rest guidance, depending on the positional relationship between the current position and SA/PA. This appropriately promotes rest at SA/PA. In addition, when there are multiple SA/PAs that can be visited, the control unit 17 determines a suitable SA/PA for taking a break (also referred to as a "recommended SA/PA") according to the level of facilities. , reflected in the audio output of the break guidance and the display of the guidance image Im.

(1) Processing Overview FIG. 3 is an example of a flowchart showing a method of controlling break guidance executed by the control unit 17. In the flowchart of FIG. 3, the control unit 17 sets the standard time of the break threshold Tth to 2 hours, and sets the break time so that the vehicle Ve can take a break at SA/PA as much as possible according to the positional relationship between the current position and SA/PA. The threshold value Tth is flexibly varied between 1.5 hours and 2.5 hours. The two hours mentioned above are an example of the "first time" in the present invention.

First, the control unit 17 determines whether the vehicle Ve is traveling on an expressway (step S101). In this case, the control unit 17 recognizes the road on which the vehicle Ve is traveling (also referred to as the “driving road”) based on the current position measured by the GPS receiver 16 or the like and the road data stored in the storage unit 13. , it is determined whether the road the vehicle is traveling on is an expressway. If the vehicle Ve is traveling on the expressway (step S101; Yes), the control unit 17 advances the process to step S102.

On the other hand, if the vehicle Ve is not traveling on the expressway (step S101; No), the control unit 17 determines whether the continuous driving time has reached 2 hours, which is the break threshold Tth (step S103). If the continuous driving time has reached 2 hours (step S103; Yes), the control unit 17 outputs an audio break guidance to the effect that it is necessary to take a break soon for safe driving since the continuous driving time has been 2 hours. (Step S109). That is, in this case, since the driver needs a break and it is difficult for the driver to stop by the SA/PA and take a break, the control unit 17 outputs the voice guidance for the break without guiding the SA/PA. I do. On the other hand, if the continuous driving time has not reached 2 hours (step S103; No), the control unit 17 determines that there is no need to provide break guidance yet, and returns the process to step S101.

Next, in step S102, the control unit 17 determines whether there is an SA/PA that can be visited from the road on which the vehicle is traveling (step S102). For example, the control unit 17 refers to the map data and determines whether there is an SA/PA associated with the link ID of the main line of the expressway that is the road the vehicle is traveling on. In this case, preferably, the control unit 17 determines that only SAs/PAs that can be reached within 30 minutes from the current location are SAs/PAs that can be visited from the driving road. good.

When the control unit 17 determines that there is an SA/PA that can be visited from the road on which the vehicle is traveling (step S102; Yes), the control unit 17 determines whether 1.5 hours of continuous driving time have elapsed (step S104). Then, when the continuous operation time has passed for 1.5 hours (step S104; Yes), the control unit 17 performs a guide image display process of determining the recommended SA/PA and displaying the guide image Im (step S104; Yes). S106). The guide image display process will be described later with reference to FIG. 4. For example, when the vehicle Ve approaches within a predetermined distance from the nearest SA/PA (also referred to as "nearest SA/PA"), the control unit 17 controls the nearest SA/PA or the recommended SA/PA. A voice message indicating that the user should take a break is output from the PA (step S109).

In this way, if 1.5 hours of continuous operation has elapsed and there is an SA/PA that can be visited, the control unit 17 shortens the break threshold Tth from 2 hours to a maximum of 30 minutes and takes a break. Provide guidance. Thereby, the control unit 17 can prevent the driver from providing rest guidance after passing a SA/PA where the driver can stop by, and can suitably allow the driver to take a break at the SA/PA. Note that the break threshold Tth after being shortened from 2 hours is an example of the "second time" in the present invention.

On the other hand, if the continuous operation time has not passed for 1.5 hours (step S104; No), the control unit 17 displays the guide image Im of the most recent SA/PA (step S105). In this case, the control unit 17 may display the guide image Im of the most recent SA/PA only when the most recent SA/PA exists on the displayed map. Then, the control unit 17 returns the process to step S101 without executing step S109. That is, in this case, the control unit 17 determines that there is still little need to take a break, does not provide audio guidance to the effect that a break should be taken, and causes only the presence of the most recent SA/PA to be visually recognized using the guidance image Im.

On the other hand, in step S102, if the control unit 17 determines that there is no SA/PA that can be visited from the driving road (step S102; No), it determines whether the continuous driving time has reached 2 hours (step S107). If the continuous operation time has reached 2 hours (step S107; Yes), the control unit 17 determines whether there is an SA/PA that can be reached within 30 minutes on the guide route (step S108). ). The above-mentioned 30 minutes is an example of an allowable time that can exceed two hours, which is the standard time for the break threshold Tth, from the viewpoint of reduced concentration due to driving fatigue, for example. On the other hand, if the continuous driving time has not reached 2 hours (step S107; No), the control unit 17 determines that there is no need to provide break guidance yet, and returns the process to step S102.

If the control unit 17 determines that there is an SA/PA that can be reached within 30 minutes (step S108; Yes), the control unit 17 returns the process to step S102 again. That is, in this case, the control unit 17 determines that it is appropriate to take a break at the next SA/PA even if the standard time of 2 hours for the break threshold Tth is exceeded within the allowable range. , break guidance will not be provided at this time. Thereafter, when the control unit 17 approaches within a predetermined distance from the SA/PA, the control unit 17 displays a guidance image Im for the SA/PA in step S105 or S106, and outputs an audio break guidance in step S109. I do. In this way, by flexibly extending the break threshold Tth, the control unit 17 can suitably output the voice guidance for a break at a timing when it is possible to stop by the SA/PA. Note that in this case, the extended break threshold Tth is an example of the "fourth time" in the present invention.

On the other hand, if the control unit 17 determines that there is no SA/PA that can be reached within 30 minutes (step S108; No), the continuous driving time has reached the break threshold Tth of 2 hours, so a break is required. A voice guidance to the effect that it is necessary is output (step S109). That is, in this case, the control unit 17 determines that there is no plan to pass through the SA/PA even after two and a half hours, which is the upper limit that can be set as the break threshold Tth, and instructs the driver to take a voluntary break. prompt.

(2) Guide Image Display Process Next, the guide image display process executed in step S106 in FIG. 3 will be described. FIG. 4 is an example of a flowchart showing the guide image display process.

First, the control unit 17 recognizes the SA/PA (also referred to as "semi-proximal SA/PA") located beyond the most recent SA/PA (step S200). Specifically, in this case, the control unit 17 recognizes an SA/PA that can arrive within a predetermined time from the most recent SA/PA. The above-mentioned predetermined time is an example of the "third time" in the present invention, and is set to, for example, 30 minutes. Preferably, the control unit 17 may limit the number of semi-nearest SA/PAs to two or less.

Next, the control unit 17 calculates the degree of sufficiency of each of the facilities in the nearest SA/PA and the semi-nearest SA/PA (step S201). For example, the control unit 17 refers to the facility information in the map data, counts the number of facilities (stores) accommodated in each SA/PA, and calculates the counted number of facilities as the degree of fulfillment of the SA/PA. . Note that the control unit 17 counts only the number of facilities (for example, restaurants, food codes, coffee shops, etc.) that allow rest among the facilities (stores) accommodated in each SA/PA, and increases the number of facilities counted. It may be determined as a degree.

Next, the control unit 17 determines whether there is a semi-nearest SA/PA that has a higher degree of fulfillment than the immediate SA/PA (step S202). Then, if there is a semi-nearest SA/PA with a higher degree of fulfillment than the most recent SA/PA (step S202; Yes), the control unit 17 recognizes the semi-nearest SA/PA as the recommended SA/PA, and These guide images Im are displayed together with PA (step S203). Here, if there are a plurality of quasi-nearest SA/PAs with a higher degree of fulfillment than the most recent SA/PA, the control unit 17 determines the quasi-nearest SA/PA with the highest degree of fulfillment among them as the recommended SA/PA, The guide image Im of the recommended SA/PA and the most recent SA/PA may be displayed. Then, when the control unit 17 approaches within a predetermined distance from the most recent SA/PA or the recommended SA/PA, the control unit 17 outputs audio guidance indicating that the near-nearest SA/PA is more fulfilling than the most recent SA/PA. (Step S204). Thereafter, in step S109 of FIG. 3, the control unit 17 provides audio guidance to the effect that the user should take a break at the most recent SA/PA or the semi-most recent SA/PA.

In this manner, in steps S203 and S204, the control unit 17 actively guides the driver to the semi-nearest SA/PA, which has more extensive facilities than the nearest SA/PA, as the recommended SA/PA. Thereby, the control unit 17 can suitably allow the driver to take a break at the SA/PA where facilities are abundant.

On the other hand, if there is no semi-nearest SA/PA with a higher degree of fulfillment than the latest SA/PA (step S202; No), the control unit 17 displays the guide image Im of the latest SA/PA (step S205). That is, in this case, the control unit 17 determines that there is no other SA/PA to draw the driver's attention to than the most recent SA/PA, and displays only the guide image Im of the most recent SA/PA. Thereafter, in step S109 of FIG. 3, the control unit 17 outputs a voice indicating that the user should take a break at the nearest SA/PA when the vehicle approaches the nearest SA/PA within a predetermined distance.

(3) Display example Next, a display example of the guide image Im will be described. First, an example in which only the guide image Im of the most recent SA/PA is displayed will be described with reference to FIGS. 5 and 6.

FIG. 5 shows a display example of the display 110 when displaying the guide image Im of the most recent SA/PA in step S105 of FIG. 3 or step S205 of FIG. In the example of FIG. 5, the vehicle indicated by the current position mark 21 is traveling on the road 20 in the down lane that connects the parking area "XXPA" located at point 22A and the service area "○○SA" located at point 22B. Assume that the vehicle is running.

In FIG. 5, the control unit 17 displays on the display 110, as a guide image Im, a speech bubble 23A indicating the position of the parking area "XXPA", which is the nearest SA/PA where you can stop by, on the surrounding map of the current location. I'm letting you do it. In the speech bubble 23A, facility icons 25A representing facilities accommodated in the parking area "XXPA" are displayed side by side. In this way, when not providing break guidance or when providing break guidance using the most recent SA/PA as the recommended SA/PA, the control unit 17 displays a simple display indicating the location of the most recent SA/PA and the accommodation facility. The speech balloon 23A is displayed as the guide image Im.

FIG. 6 shows an example of the display on the display 110 when the speech bubble 23A is selected in the example of FIG. In the display example of FIG. 6, the control unit 17 detects through the touch panel 120 that the speech bubble 23A is touched by a finger or the like, and displays a detailed display window showing the arrangement of each facility in the parking area "XXPA" along with facility marks. 29A is displayed at the bottom of the display 110. In this way, when the driver selects the balloon 23A, the control unit 17 displays detailed information in the parking area "XXPA" as the guide image Im.

Note that when displaying the guide image Im of the most recent SA/PA as the recommended SA/PA in step S205, the control unit 17 may immediately display the details display window 29A of FIG. 6 instead of the balloon 23A of FIG. good. Thereby, the control unit 17 can suitably make the driver recognize detailed information about the most recent SA/PA where the driver is expected to stop for a break.

Next, display examples (first display example, second display example) on the display 110 in step S203 when the near-nearest SA/PA is set as the recommended SA/PA will be described with reference to FIGS. 7 and 8. .

FIG. 7 shows a first display example of the display 110 when displaying the guide image Im of the semi-nearest SA/PA together with the immediate SA/PA in step S203. In this case, the control unit 17 determines that the service area "○○SA" located beyond the nearest parking area "XXPA" accommodates more facilities and has a higher level of facilities. Then, the service area "○○SA" is recognized as the recommended SA/PA. In this case, the control unit 17 displays a detailed display window 29B showing detailed information of the service area "○○ SA" and details showing detailed information of the parking area "XX PA" which is the most recent SA/PA. The display window 29A is displayed on the map.

In this way, in the first display example shown in FIG. 7, the control unit 17 displays the detailed display window 29A of the most recent SA/PA as well as the near-most recent SA/PA that has more facilities than the most recent SA/PA. The windows 29B are displayed side by side. As a result, the control unit 17 allows the driver to suitably select which of the nearest SA/PA and the semi-nearest SA/PA, which has more facilities than the nearest SA/PA, should be used as a resting place. can.

FIG. 8 shows a second display example of the display 110 when displaying the guide image Im of the semi-nearest SA/PA together with the immediate SA/PA in step S203. In this case, the control unit 17 displays a speech bubble 23A showing simple information about the parking area "XXPA" which is the nearest SA/PA, and also displays a service area with more facilities than the parking area "XXPA". A balloon 23B showing simple information of "○○SA" is displayed. Furthermore, since the service area "○○SA" is the recommended SA/PA, the control unit 17 informs the speech balloon 23B for the service area "○○SA" that the balloon 23B is the recommended SA/PA. The highlighted image 30 shown in FIG.

In this way, in the second display example shown in FIG. 8, the control unit 17 displays a speech balloon 23A for the most recent SA/PA as well as a speech balloon 23B for the semi-proximal SA/PA that has more facilities than the most recent SA/PA. and highlights the speech bubble 23B. Thereby, the existence of the semi-proximal SA/PA, which has more extensive facilities than the proximal SA/PA, can be suitably made visible to the driver.

As described above, the terminal device 100 according to this embodiment includes the output section 11, the GPS receiver 16, and the control section 17. The control unit 17 acquires information regarding the current position of the vehicle Ve from the GPS receiver 16. The control unit 17 causes the output unit 11 to output rest information for urging the driver to take a break when the continuous driving time has exceeded two hours, which is the standard time of the break threshold Tth. Then, the control unit 17 changes the rest threshold Tth from the standard time of 2 hours based on the positional relationship between the vehicle Ve and the rest facility. By doing so, the terminal device 100 can flexibly change the timing of providing rest information based on the positional relationship between the mobile object and the rest facility, and allow the driver to appropriately take a break at the rest facility. .

[Modified example]
Hereinafter, each modification suitable for the above-mentioned embodiment will be explained. Note that each of these modified examples can be combined arbitrarily and applied to each of the above-mentioned embodiments.

(Modification 1)

FIG. 9 shows a configuration example of a system according to a modified example. As shown in FIG. 9, the terminal device 100 is connected to a server device 200 via a network 150. Then, the terminal device 100 performs route guidance etc. by receiving information necessary for route guidance from the server device 200.

FIG. 10 shows a schematic configuration of the server device 200. As shown in FIG. 10, the server device 200 includes a communication section 202, a storage section 203, and a control section 204. The communication unit 202, the storage unit 203, and the control unit 204 are interconnected via a bus line 201.

The communication unit 202 transmits and receives various data via the network 150 under the control of the control unit 204 . The storage unit 203 includes, for example, an HDD, and stores data necessary for route searching, such as map data. The control unit 204 has a CPU and memories such as ROM and RAM, and performs general control of the server device 200 by executing programs stored in the memory.

In this case, the control unit 204 performs a search process for a guide route that the vehicle Ve should travel based on the current position information, destination information, etc. transmitted from the terminal device 100, and transfers information on the searched guide route to the terminal device. Send to 100. Further, the control unit 204 performs the processes shown in FIGS. 3 and 4 based on the current position information etc. transmitted from the terminal device 100, determines the output timing and output content of the break guide and the guide image Im, and determines the output timing and output content of the break guide and guide image Im. A signal instructing to output audio and display the guide image Im is transmitted to the terminal device 100. Note that the control unit 204 may display each display screen shown in FIGS. 5 to 8 on the display 110 by generating display information for the screen to be displayed on the display 110 and transmitting it to the terminal device 100. .
