[First Embodiment]
Hereinafter, the present embodiment will be described with reference to the drawings.
FIG. 1 is a diagram for explaining an outline example of a navigation system 1 according to the present embodiment. As shown in FIG. 1, the navigation system 1 includes an information providing apparatus 100 a, an information providing apparatus 100 b, and a navigation apparatus 200. The parking lot 10 is, for example, a three-dimensional parking lot, and is a place deployed along with the facility. The facility is, for example, a store, a department store, a shopping center where a plurality of stores are gathered, a complex building, and the like.
In the following description, when one of the information providing apparatus 100a and the information providing apparatus 100b is not specified, the information providing apparatus 100 is simply referred to.

  The information providing apparatus 100 a is installed near the entrance 10 a of the parking lot 10, and the information providing apparatus 100 b is installed inside the parking lot 10. Note that the information providing apparatus 100 a and the information providing apparatus 100 b are arranged at positions corresponding to the course of the vehicle 20. For example, when the vehicle 20 enters the parking lot 10, the vehicle 20 is first arranged at a position that passes through the communication area of the information providing apparatus 100 a, and then is arranged at a position that passes through the communication area of the information providing apparatus 100 b.

The information providing apparatus 100a transmits position and orientation information to the navigation apparatus 200 by communicating with the navigation apparatus 200 of the vehicle 20 that passes through the communication area of the information providing apparatus 100a. The information providing apparatus 100 a transmits additional information to the navigation apparatus 200 in response to a transmission request for additional information received from the navigation apparatus 200 (hereinafter referred to as an additional information request).
The information providing apparatus 100b communicates with the navigation apparatus 200 of the vehicle 20 that passes through the communication area of the information providing apparatus 100b, thereby transmitting the position and orientation information to the navigation apparatus 200. The information providing apparatus 100 b transmits additional information to the navigation apparatus 200 in response to the additional information request received from the navigation apparatus 200.

Here, the position / orientation information refers to position information indicating the position of a specific place where the information providing apparatus 100a or the information providing apparatus 100b is installed, and an orientation indicating a specific direction determined in advance corresponding to the specific place. Information including information. The position / orientation information in the example of FIG. 1 includes position information indicating the position of the entrance / exit 10a and orientation information indicating an orientation according to the traveling direction of the vehicle 20 when passing through the entrance / exit 10a.
Further, the additional information is information for a user who is in the vehicle. For example, store event information, sale information, coupons, floor guides in the store, point grants, messages, parking This is empty area information, advertisements, etc. in the car park 10.

  The navigation device 200 is provided in the vehicle 20 that is a moving body. The moving body is, for example, an automobile, a motorcycle, a motorcycle, a wheelchair, or the like. The navigation apparatus 200 obtains positioning information by performing positioning corresponding to a positioning system such as GPS (Global Positioning System) or GNSS (Global Navigation Satellite Systems). That is, a positioning calculation is performed by receiving a signal from a positioning satellite. The positioning information obtained by this positioning calculation includes information on the current position and the traveling direction that have been measured. In addition, the navigation device 200 performs positioning by autonomous navigation when it cannot receive a signal from a positioning satellite because it is located indoors or in a place with many high-rise buildings. For example, the navigation device 200 estimates the current position and the traveling direction by using information such as the speed of the vehicle 20 detected by a vehicle speed pulse and the traveling direction detected by a gyro sensor, an acceleration sensor, or the like as positioning by autonomous navigation. To do. And the navigation apparatus 200 displays the navigation screen which shows an own position and advancing direction on a display part based on the positioning information obtained as mentioned above.

  In addition, the navigation device 200 receives the position and orientation information transmitted by the information providing device 100 and causes the display unit to display a navigation screen indicating its own position and traveling direction based on the received position and orientation information. The navigation device 200 transmits an additional information request to the information providing device 100. This additional information request includes user preference data such as a genre desired by the user and information desired to be sent. Note that the navigation device 200 transmits an additional information request to the information providing device 100 and receives the additional information when the user operates the operation element provided in the own device to allow the reception of the additional information. When the setting is made to reject, the additional information request is not transmitted to the information providing apparatus 100. In addition, the user preference data is set in advance by operating the operator provided in the navigation device 200 by the user. The navigation device 200 receives the additional information transmitted by the information providing device 100 and displays the received additional information on the display unit of the navigation device 200.

  Here, in the parking lot 10, the radio wave from the positioning satellite of the positioning system is blocked. For this reason, the navigation apparatus 200 of the vehicle 20 in the parking lot 10 cannot perform positioning by using the positioning system. Therefore, the navigation device 200 in this case measures the current position and the traveling direction by autonomous navigation. However, autonomous navigation is not necessarily accurate. For example, since the passage is spiral in the parking lot 10, the vehicle 20 moving in the parking lot 10 almost always changes direction. For this reason, a situation in which the position indicated by the positioning information obtained by autonomous navigation and the traveling direction greatly deviate from the actual position and traveling direction is likely to occur.

FIG. 2 is a diagram illustrating an example of a navigation screen displayed on the navigation device 200. FIG. 2A is an example of a navigation screen in the vicinity of the entrance 10a, and FIG. 2B is displayed when the position of the navigation screen and the display of the traveling direction in FIG. It is an example of a navigation screen. In FIG. 2A to FIG. 2C, a mark 300 is a mark indicating the own vehicle position. 2A and 2C, an image 310 is an image showing that the position and orientation are received from the information providing apparatus 100 and the position and orientation are corrected. Further, in FIG. 2C, an image 320 is an image in which the additional information received from the information providing apparatus 100 is displayed on the display unit.
For example, the navigation screen displayed when the vehicle 20 is about to leave the entrance 10a should be as shown in FIG. In FIG. 2A, the mark 300 is located at the entrance 10a, and the traveling direction indicated by the mark 300 also coincides with the orientation that the vehicle 20 will actually face when leaving the entrance 10a. . Note that the example shown in FIG. 2A is an image of the display unit when the user refuses to receive additional information.

  On the other hand, the navigation screen displayed when the vehicle 20 is about to leave the entrance 10a when the positioning information obtained by the autonomous navigation greatly deviates from the actual position and the traveling direction is, for example, FIG. )become that way. That is, the mark 300 is far away from the entrance 10a, and the traveling direction indicated by the mark 300 is considerably different from the orientation when exiting the entrance 10a. If such a navigation screen is displayed, the user who is driving the vehicle 20 cannot determine which direction to proceed after leaving the doorway 10a.

  Even if the positioning satellite signal returns to a state in which the positioning satellite signal can be received in the vicinity of the entrance 10a, it takes a relatively long time to obtain the positioning information based on the signal whose reception has been resumed. For this reason, it is difficult to display the navigation screen based on the positioning information obtained by positioning using the positioning system at the timing when exiting the entrance 10a, and the display is also as shown in FIG.

  As shown in FIG. 2C, when the setting for permitting the reception of the additional information is made by the user, an image 320 of the additional information is displayed on the display unit of the navigation device 200. Note that the image of the additional information may be displayed on a screen different from the navigation image. Alternatively, information indicating that the additional information has been received may be displayed on the display unit, and the additional information may be displayed in response to a user instruction.

For example, for each store, sales information for each day of the week, sales information for each hour, sales information for rainy days, and the like may be associated and stored.

The communication control unit 130 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and the like, and controls the communication unit 140 for communication with the navigation device 200. For example, the communication control unit 130 determines whether or not the navigation device 200 exists in the communicable range based on the strength of the received signal input from the communication unit 140. Further, when connection establishment or authentication is required in the communication method with the navigation apparatus 200, processing for such connection establishment or authentication is executed.
Furthermore, the communication control unit 130 includes a transmission control unit 131. The transmission control unit 131 reads the position / orientation information from the position / orientation information storage unit 110 and causes the communication unit 140 to transmit the read position / orientation information to the navigation device 200 located in the communicable range of the communication unit 140. The transmission control unit 131 selects additional information to be transmitted to the navigation apparatus 200 in response to the additional information request received by the information providing apparatus 100a and the information providing apparatus 100b. Then, the transmission control unit 131 causes the communication unit 140 to transmit the selected additional information to the navigation device 200. The additional information request includes user preference data described later.
