Description

  The present invention relates to a facility selection apparatus and a facility selection method for searching for facilities that can be obtained by using facilities, services, products, and the like requested by a user as keys, and selecting a facility that best suits the user's preference among them.

The current car navigation system provides basic directions such as instructing the route to the destination and searching for the optimum route to the destination using real-time traffic information obtained from the Road Traffic Information System (ITS). It has various additional information providing functions as well as various functions.
For example, information on desired facilities (for example, stations, parks, restaurants, parking lots, gas stations, accommodation facilities, etc.) can be displayed by displaying the positions of various facilities on a map on the display unit or inputting conditions. Can also be displayed.

As described above, the car navigation device is provided with various information providing functions. However, the information is limited only by the information included in the car navigation device, and wrong information is provided unless the information is sequentially updated. Recently, information related to the facility is registered in the facility information management center, communicated with the facility information management center via the network such as the Internet from the car navigation device, and registered in the facility information management center. It is beginning to take facility information into the car navigation system.
By sequentially updating the facility information stored in the facility information management center, the user can always obtain information on the latest facility via the car navigation device.

However, in the past, the user specified the name of the target facility, and the facility was searched for, and only the facility information for the facility alone could be checked to see if there was a service. When there was a vague request such as, it was not possible to meet the request. For this reason, it has been proposed to search for facilities based on information on the services of each facility, information on whether or not they are in business (see, for example, Patent Document 1).
JP-A-8-138193

  As mentioned above, conventionally, when you want a specific service or product, you can check the facility information for a single facility and check whether there is a service, but if you want to compare the services of each facility, The user had to search manually and was troublesome. In particular, if there are a wide variety of facilities such as toilets and ATMs that can receive services, work must be started from the selection of facilities. There was also a case.

On the other hand, as described above, it has been proposed to search for facilities based on information on the services of each facility, information on whether or not they are operating, etc. It does not consider whether the facility providing the service is close to the route to the destination, the service fee, the suitability of the facility equipment, the distance to the facility, etc. When a facility is retrieved and output, the user himself / herself has to search for a facility that meets the user's preference from among a large number of facilities.
In addition, if the service at a certain location does not meet your preference or you cannot receive the service for your convenience, you can also determine whether you can receive a service that suits your preference on the route to the destination after that. Have difficulty.

  The present invention has been made in view of the above problems. When a user requests a specific facility, service, product, etc., the user can be guided to a facility that suits the user's preference, and the user's judgment An object of the present invention is to provide a facility selection apparatus and a facility selection method that can prevent mistakes and help a user to make a correct selection.

In order to achieve the above-described object, the facility selection device (1) according to the present invention includes:
A facility selection device comprising a control means for searching for facilities using equipment, services, products, etc. as a key,
The control means searches for a facility within a predetermined range with the key, and selects the optimal facility by weighting the searched and output facility based on various conditions of the facility.

Moreover, the facility selection device (2) according to the present invention is the facility selection device (1).
The weighting condition includes at least two of a facility location direction, a distance to the facility, facility convenience, and user evaluation.

Furthermore, the facility selection device (3) according to the present invention is the facility selection device (1) or (2),
When the number of facilities retrieved and output is equal to or less than a predetermined number, the control means presents a required time to a facility outside the predetermined range.

Moreover, the facility selection device (4) according to the present invention is the facility selection device (2) or (3),
The control means stores the user evaluation input when using the selected facility in the storage means and / or registers it in the facility database.

Furthermore, the facility selection device (5) according to the present invention is the facility selection device (4).
When the vehicle stops near the selected facility and the door is opened and closed, it is determined that the facility has been used, and a user evaluation request screen is displayed.

Moreover, the facility selection method (1) according to the present invention includes:
A facility selection method for selecting a facility using facilities, services, products, etc. as a key,
A facility within a predetermined range is searched with the above key, and the optimal facility is selected by weighting the searched and output facility based on various conditions of the facility.

According to the facility selection devices (1) and (2) and the facility selection method (1) according to the present invention, facilities are searched using equipment, services, products, and the like as keys, so that the user can receive services and the like. You can also search for places that you did not know as candidates, and each facility is weighted based on conditions such as the location of the facility, the distance to the facility, the convenience of the facility, user evaluation, etc., and the optimal facility is selected Therefore, it is possible to guide the user to a place that satisfies the user's preference.
In other words, the facility is selected based on whether it is in a location along the route, whether it is an easy-to-use facility, or whether the user evaluation is high, etc. The user can be guided to a suitable facility.

In addition, according to the facility selection device (3) according to the present invention, when the number of facilities retrieved and output is equal to or less than the predetermined number, the required time to the facility outside the predetermined range is presented, so the user's preference is satisfied. If the service can be received at a nearby place, but if the opportunity is missed, it will take time until the next place to receive the service, the user can know that.
In other words, if there is a place that meets the requirements, but it passes by thinking that the other places meet the requirements more, it is possible to prevent a decision error such that the next place that meets the requirements is not found. Therefore, it is possible to help the user to make a correct selection.

Furthermore, according to the facility selection device (4) according to the present invention, when the selected facility is used, the user evaluation is registered in the in-vehicle terminal device or the facility database, and it is bad when the user is dissatisfied with the facility. By inputting the evaluation, it is possible to lower the selection priority of the place or a similar place, so that it is possible to further select a facility that suits the user's preference.
Moreover, according to the facility selection device (5) according to the present invention, when the vehicle stops near the selected facility and the door is opened and closed, it is determined that the facility has been used, and an evaluation input request is sent to the user. Since the screen is automatically displayed, the user can easily input the evaluation.

  Embodiments of the facility selection device of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic block diagram of an entire system to which a facility selection apparatus of the present invention is applied. 1 is an in-vehicle terminal device mounted on a vehicle 2, 3 is a facility information management center, 4 to 7 are convenience stores, multi-use buildings, It is a facility such as a JR station or a park, and facility information such as equipment and sales items of each facility is periodically transmitted from these facilities to the facility information center 3 as a list.

  The in-vehicle terminal device 1 is connected to the facility information management center 3 through a communication device such as a mobile phone so as to be able to transmit information to the facility information management center 3 and communicates with the facility information management center 3 not only in a stopped state but also in a traveling state. Can do. In addition, although this vehicle-mounted terminal device 1 can be added as a part of function of a vehicle-mounted navigation apparatus, it can also be comprised as an independent apparatus.

  FIG. 2 is a block diagram showing a specific configuration of the in-vehicle terminal device 1. As shown in FIG. 2, the in-vehicle terminal device 1 stores a position detection unit 11 as position detection means, map data, and facility information. A map data storage unit 12, a display unit 13, an input unit 14, a memory unit 15, an audio output unit 16, a data communication unit 17, and a control unit 18.

  The position detection unit 11 includes a GPS sensor, a gyro sensor, and the like, and detects the current position and traveling direction of the vehicle. The map data storage unit 12 includes a DVD player, an HDD (hard disk driver), and the like, and road map data The map data including and information on the facility are stored. The display unit 13 is a display device for displaying a map or displaying an evaluation input screen when selecting a facility, and the input unit 14 is attached to the left and right or top and bottom of the display device of the display unit 13. The user can make various instructions and input facility evaluations via the input unit 14.

  The memory unit 15 includes, for example, a ROM and a RAM (not shown). The ROM stores a program for executing various processes including a navigation program, and the RAM temporarily stores the program at the time of program execution. An area for temporarily storing various data and data acquired from the map data storage unit 12 is formed. The voice output unit 16 outputs a voice for navigating the user, and the data communication unit 17 has a mutual communication function, and is configured by, for example, a mobile phone, a car phone, a beacon, or the like.

  The control unit 18 controls the above-described units of the in-vehicle terminal device 1, and includes a map data acquisition unit 21, a route calculation unit 22, a route guide unit 23, a drawing unit 24, a screen control unit 25, a communication control unit 26, and a facility selection. The unit 27 and the facility evaluation unit 28 are configured by a CPU, a ROM, a memory such as a RAM, a HDD, and the like, and the functions of the units are executed by software.

  The map data acquisition unit 21, the route calculation unit 22, the route guidance unit 23, the drawing unit 24, and the screen control unit 25 have the same functions as those of a normal car navigation device, and the communication control unit 26 uses the input unit 14. When the user makes a service search request, the data communication unit 17 is instructed so that mutual communication with the facility information management center 3 is possible. When mutual communication becomes possible in this manner, the communication control unit 26 notifies the facility information management center 3 of the current position information detected by the position detection unit 11.

  The facility selection unit 27 selects a facility that meets the user's preference based on the facility information transmitted from the facility information center 3 and displays it on the display unit 13, and the facility evaluation unit 28 prompts the user when using the facility. Requesting an evaluation input, registering the input evaluation in the memory unit 15 and transmitting it to the facility information management center 3.

  On the other hand, the facility information management center 3 includes a database 31 in which information on a large number of facilities such as convenience stores, parks, buildings, stations, hotels, leisure facilities, shops, restaurants, gas stations, or parking lots is registered. In this database 31, for example, as shown in FIGS. 3A and 3B, “building ID”, “name”, “type of facility”, “address”, “phone number”, “ Information such as “Direction of entrance”, “Equipment”, “Service contents”, “Products handled” is registered, and information that changes over time, such as the number of products in stock, is transmitted from each store or chain headquarters as appropriate. Has been updated.

Next, an operation when the user inputs a service and searches for a facility that best suits the taste will be described using a flowchart and a display screen in the in-vehicle terminal device 1.
When the user inputs a destination from the input unit 14, the map data acquisition unit 21 of the control unit 18 acquires the current position of the vehicle from the position detection unit 11 and acquires the current position from the map data storage unit 12 as in a normal car navigation device. A map of the vehicle position is acquired, the route calculation unit 22 calculates a route to the destination based on the information on the map, and the route guide unit 23 controls the drawing unit 24 and the screen control unit 25 to display the display unit. A map and a route near the vehicle are displayed at 13.
In this state, when the user selects a service, for example, a toilet, on the facility search screen displayed on the display unit 13 and instructs the search, the facility selection unit 27 of the control unit 18 executes the facility selection program shown in the flowchart of FIG. First, a facility having a toilet in the facility attribute is searched (step 101).

FIG. 5 is a flowchart showing the facility search subroutine program. When this subroutine program is started, the facility selection unit 27 reads the current position and search range of the vehicle captured from the position detection unit 11, for example, within a radius of 5 km, Is transmitted to the facility information management center 3 via the data communication unit 17 (step 201).
As a result, the facility information management center 3 searches for facility information in the facility database 31 and transmits information on facilities within a radius of 5 km from the vehicle position to the in-vehicle terminal device 1.

The facility selection unit 27 determines whether or not the facility information is received from the facility information management center 3 after transmitting the vehicle position / search range to the facility information management center 3 (step 202). When the facility information is received from 3, the received information on many facilities is stored in the memory unit 15 (step 203).
Next, the facility selection unit 27 selects one of the stored facilities (step 204), and then determines whether or not a toilet exists in the facility based on the information on the facility (step 205). If it is determined that the facility has a toilet, the facility is added to the candidate list in the memory unit 15 (step 206).

  When it is determined in step 205 that there is no toilet in the facility, or after the facility is added to the candidate list in step 206, the facility selection unit 27 determines whether or not there are toilets for all the facilities stored in the memory unit 15. It is determined whether or not it has been checked (step 207). If there are still unchecked facilities, the process returns to step 204 to check the next facility, and it is determined that all facilities have been checked. Then, the subroutine program is terminated.

In the flowchart of FIG. 4, when the search for the facility having the toilet is completed, the facility selecting unit 27 weights each facility listed in the candidate list with the superiority of the position (step 102).
FIG. 6 is a flowchart showing a subroutine program for weighting the position advantage. When this subroutine program is started, the facility selection unit 27 acquires the current position and direction vector of the vehicle from the position detection unit 11 (step 301). Then, one of the facilities in the candidate list is selected (step 302). Next, the facility selection unit 27 obtains the position of the selected facility based on the address of the facility stored in the memory unit 15 (step 303), and then determines whether the target facility is ahead in the traveling direction. If it is determined that the target facility is not in front of the traveling direction, the weighting point of the facility is set to 1 (step 305).

If it is determined in step 304 that the target facility is ahead in the traveling direction, the facility selection unit 27 determines whether the target facility is on the right side along the route (step 306), and if the target facility is on the right side along the route. If determined, the weighting point of the facility is set to 4 (step 307).
If it is determined in step 306 that the target facility is not on the right side along the route, the facility selection unit 27 determines whether the target facility is on the left side along the route (step 308), and the target facility is on the left side along the route. If it is determined that there is, the weighting point of the facility is set to 5 (step 309), and if it is determined in step 308 that the target facility is not on the left side along the route, the weighting point is set to 3 (step 310).

  When the weighting of the selected facility is completed, the facility selecting unit 27 determines whether or not all the facilities listed in the candidate list have been weighted (step 311), and the facilities that have not yet been weighted remain. If YES in step 302, the next facility in the candidate list is selected, and if it is determined that all facilities in the candidate list have been weighted, the subroutine program is terminated.

In the flowchart of FIG. 4, when the weighting of the superiority of the position of the facility in the candidate list is completed, the facility selecting unit 27 performs the weighting of the superiority of the distance of each facility listed in the candidate list (step 103).
That is, the facility selection unit 27 calculates the distance between the position of the host vehicle and the facility on the candidate list. For example, a facility having a distance within 1 km is 5 points, a facility having a distance of 1 km to 2 km is 4 points, and a distance is 2 km. 3 points for facilities of 3 km, 2 points for facilities of 3 km to 4 km, 1 point for facilities of 4 km to 5 km, and 0 points for facilities of 5 km or more.

Next, the facility selection unit 27 weights each facility listed in the candidate list with the convenience of facility convenience (step 104).
FIG. 7 is a flowchart showing a subroutine program for weighting facility convenience. When this subroutine program is started, the facility selection unit 27 selects one of the facilities in the candidate list (step 401). It is determined whether or not the target facility is a public toilet based on the information on the facility stored in the memory unit 15 (step 402), and when it is determined that the target facility is a public toilet, 3 is assigned to the weighting point of the facility. Add (step 403).

If it is determined in step 402 that the target facility is not a public toilet, the facility selection unit 27 determines whether the target facility is a railway station or building (step 404), and the target facility is a railway station or building. If determined, 2 is added to the weighting point of the facility (step 405).
When it is determined in step 404 that the target facility is not a railway station or building, the facility selection unit 27 determines whether or not the target facility is a convenience store (step 406), and determines that the target facility is a convenience store. In this case, 1 is added to the weighting point of the facility (step 407), and when it is determined that the target facility is not a convenience store, 0 is added to the weighting point (step 408).

  When the addition of the weighting points for convenience of the selected facility ends, the facility selection unit 27 adds points based on user evaluation (step 409). As shown in FIG. 3, the user evaluation points are stored in the memory unit 15 because the evaluation by the general user is registered in five stages for each facility of the facility registered in the facility information management center 3. It can be read out from the information of each facility that has been used, and the memory unit 15 can be used for the facility or a facility similar to the facility, for example, when the facility is a convenience store, other convenience stores. If the user's evaluation is stored, the evaluation can be added.

  When the point addition by the user evaluation is completed, the facility selecting unit 27 determines whether or not the weighting points have been added to all the facilities listed in the candidate list (step 410), and the weighting points are still being added. If there is no facility remaining, the process returns to step 401 to select the next facility in the candidate list, and if it is determined that the addition of weighting points to all facilities in the candidate list is completed, the subroutine program is terminated.

Then, in the flowchart of FIG. 4, when the weighting of the convenience of the facilities on the candidate list is completed, the facility selection unit 27 adds the points of each facility on the candidate list and displays the facility with the highest point on the map of the display unit 13. To display.
That is, the facility selection unit 27 searches the facility related to the facility with the highest point from the information related to the facility stored in the map data storage unit 12, and displays the route to the facility, for example, thereby allowing the user to the facility. invite.

  Instead of displaying the route to the facility, the name and location of the facility are displayed on the display unit 13 in the order of the highest point, or the name and location of the facility with the highest point are notified by voice by the audio output unit 16. In addition, as an advantage of the facility, it is possible to add points by judging how far the facility is away from the traveling route of the vehicle, whether there is a parking lot, etc. .

Next, the operation when inputting the user evaluation used in step 409 of the flowchart of FIG. 7 will be described with reference to the flowcharts of FIGS.
After the facility having the highest point is displayed in step 105 of the flowchart of FIG. 4, the facility evaluation unit 28 starts the facility use determination program shown in the flowchart of FIG. It is determined whether or not the facility is displayed on the screen (step 501). If the facility is not displayed on the map display screen of the display unit 13, the program is terminated and the facility is displayed on the map display screen of the display unit 13. If the facility is displayed, the current position of the vehicle is fetched from the position detector 11 (step 502).

Next, the facility evaluation unit 28 determines whether or not the vehicle is currently near the facility (step 503). If it is determined that the vehicle is not near the facility, the facility evaluation unit 28 returns to step 501 and the vehicle If it is determined that the vehicle is near the facility, it is determined whether the vehicle has stopped (step 504).
If it is determined that the vehicle has not stopped, the process returns to step 501, and if it is determined that the vehicle has stopped, the facility evaluation unit 28 determines whether the door is opened and locked (step 505).

If it is determined that the door is not opened and is not locked, the process returns to step 501. If it is determined that the door is opened and locked, the facility evaluation unit 28 determines that the facility is used (step 506). Quit the program.
As described above, when the facility is not displayed on the map display screen of the display unit 13 or when it is determined that the facility is used, the program ends.

  When it is determined that the facility is used in the above program, the facility evaluation unit 28 starts the facility evaluation recording program shown in the flowchart of FIG. 9 and determines whether the door is opened again when the program is started. If it is determined that the door has been opened again (step 601), an evaluation request screen as shown in FIG. 10 is displayed on the display unit 13 (step 602).

Next, the facility evaluation unit 28 determines whether or not an evaluation is input (step 603), and when the user presses any evaluation display part of the evaluation request screen, the evaluation input by the user is displayed as the facility name and If necessary, it is stored in the memory unit 15 together with the equipment name (step 604), and then the evaluation and the facility name / equipment name are transmitted to the facility information management center 3 via the data communication unit 17 (step 605).
Thereby, the facility information management center 3 increases the evaluation point of the facility of the facility when the evaluation is “good”, and decreases the evaluation point of the facility of the facility when the evaluation is “bad”. Based on the points, the five-level evaluation of the facilities of the facility is modified.

On the other hand, when it is determined in step 603 that no evaluation is input, the facility evaluation unit 28 determines whether or not the vehicle has started (step 606), and when it is determined that the vehicle has not started, step 603 is performed. Returning to, it is determined whether or not the evaluation is input again.
If it is determined in step 606 that the vehicle has started, the facility evaluation unit 28 determines whether or not the facility has been evaluated before (step 607), and the facility is a facility that has been previously evaluated. If it is determined, the program ends, and if it is determined that the facility is not a previously evaluated facility, the user evaluation is set to “normal” and stored together with the facility name / equipment name in the memory unit 15 (step 608). Exit the program.

Thereby, when a user uses a facility, the evaluation of the facility can be registered in the in-vehicle terminal device and the facility information management center 3, and when the facility is subsequently listed in the candidate list, it is used for point addition by user evaluation. can do.
In the above embodiment, the evaluation record is executed when the facility with the highest point is used. However, when the facility is used for all the facilities listed in the candidate list. Also, an evaluation record may be performed.

  As described above, when the user designates a target facility, product or service, the facility information most suitable for the user can be presented. For example, a toilet search is instructed in the situation shown in FIG. Then, a public toilet is selected and guidance is executed.

In the above embodiment, when a search is executed by specifying a service or the like, only the facilities with high points are displayed. However, when there are few corresponding facilities, the selected facility does not meet the user's preference. In some cases, if there are few applicable facilities, you can also teach the next facility that can provide the service along the route. The operation when teaching a facility capable of providing the service will be described with reference to the flowchart of FIG.
Since the system configuration is the same as that shown in FIGS. 1 and 2, description thereof is omitted.

When the user inputs a service, for example, a souvenir product name on the facility search screen displayed on the display unit 13 to instruct a search, the facility selection unit 27 of the control unit 18 selects the facility selection program shown in the flowchart of FIG. First, a facility handling the designated souvenir is searched (step 701).
This search is executed by a program similar to the subroutine program of the flowchart of FIG. 5, and the facilities handling the designated souvenir are listed in the candidate list.

When the facility handling the designated souvenir is listed in the candidate list, the facility selection unit 27 determines whether or not three or more corresponding facilities are found (step 702), and three or more corresponding facilities are found. After weighting each facility on the candidate list according to the route, cheapness, assortment, inventory, etc. (step 703), the facility with the highest point is displayed on the map of the navigation screen of the display unit 13 ( Step 704).
The weighting of the points can be executed by a program similar to the subroutine program shown in the flowchart of FIG. 7. For example, when a souvenir search is instructed in the situation shown in FIG. Is selected and guidance is executed.

On the other hand, if it is determined in step 702 that only two or less relevant facilities have been found, the facility selection unit 27 displays the found facilities on the map of the navigation screen of the display unit 13 (step 705), and then along the route. Search for the next facility that meets the specified souvenir.
This search is executed by a program similar to the subroutine program of the flowchart of FIG. 5. For example, facility information within 20 km along the traveling route of the vehicle is fetched from the facility information management center 3, and the souvenir designated in the facility Stores that handle are listed on the candidate list.

  Next, the facility selection unit 27 determines whether or not there is a corresponding facility (step 707). If it is determined that there is a corresponding facility, the facility selection unit 27 calculates the distance to the first corresponding facility, and calculates the distance and the vehicle. After calculating the required time to the facility based on the speed (step 708), by outputting a voice such as “It will take about 20 minutes to the next store where you can buy souvenirs” from the voice output unit 16. The voice guidance for the required time to the facility is executed (step 709).

  When it is determined in step 707 that there is no corresponding facility within 20 km along the traveling route, the facility selection unit 27 reads from the audio output unit 16, for example, “There is no shop where you can buy a souvenir designated ahead. The voice guidance to the effect that there is no shop where you can buy souvenirs is executed by outputting a voice such as “??” (step 710).

As described above, when there are few applicable facilities, the presence / absence of the facility that can provide the service in front of the route is guided, so there are few applicable facilities and the selected facility does not meet the user's preference. Even in this case, the user can know whether or not the souvenir designated in the front can be bought.
In this embodiment, the presence / absence of the facility that can provide the service in front of the route is guided by voice, but the user may be notified by displaying it on the navigation screen.

  In the above embodiment, the vehicle position / search range is transmitted from the in-vehicle terminal device to the facility information management center to receive the facility information, and weighting is performed by the in-vehicle terminal device. It is also possible to transmit the service to the facility information management center and weight the corresponding facility at the facility information management center so as to select the optimum facility, and the facility database is constantly updated by the in-vehicle terminal device By providing this, information on facilities within a predetermined range from the position of the host vehicle may be retrieved by the in-vehicle terminal device without communicating with the facility information management center.

Furthermore, in the above embodiments, toilets and souvenirs have been described as examples. However, for example, in the case of a service for saving money, it is necessary to satisfy the request whether the service provided by the facility can cope with the user's account. The amount (fees) can be pointed as an advantage, and not only specific souvenirs, but anything that is related to the land may be used, so list of souvenirs representing each region It is also possible to specify a souvenir from the list when there is a souvenir search instruction by holding it in the navigation device.
Also, when selecting a souvenir facility, if there are multiple types of buildings along the route, for example, “1. Souvenir shop”, “2. Roadside station”, “3. Railway station” You can also add points in order.

In addition, the in-vehicle terminal device always determines which facility best suits the user's preference, but it is also possible to allow the user to appropriately set whether or not to provide detailed guidance by voice and navigation. is there.
In the above embodiment, when the user uses the selected facility, the evaluation of the facility is input, but the user does not select the “facility most suitable for the user” determined by the system side. In some cases, it is also possible to accumulate the data of the facility selected by the user, learn the tendency, and then guide according to the tendency when a request for guidance is received.
In this case, when there are only one or two facilities that satisfy the request, it is desirable not to perform the preference learning as described above even if the user receives a guidance to that effect and stops there.

Further, in the above embodiment, when determining whether the selected facility is used or not, if it is determined that the door is opened and locked, it is determined that the facility is used. It is possible to determine that the facility has been used by determining whether the number of people is decreasing based on the total or in-vehicle sensor.
