[0002] There is a technology related to satellite positioning that receives radio waves from multiple positioning satellites to obtain information on one's current location. The information on the current location obtained by satellite positioning is used for navigation to show the route to a destination, and is also used for services such as selectively presenting information about the vicinity of the current location.

[0003] Conventionally, civilian satellite positioning alone generally provides an accuracy of about one meter to several meters. In recent years, radio wave reception in other frequency bands with improved signal transmission content that enables more accurate identification of the current location has become widespread. In the United States' Global Positioning System (GPS), in addition to conventional civilian L1 band (1.57542 GHz) radio wave transmission, it is being replaced by positioning satellites that can also transmit radio waves in the more accurate L5 band (1.17645 GHz). Patent Document 1 discloses a technology that enables reception of both L1 band radio waves and L5 band radio waves with low power consumption. [Prior art documents] [Patent documents]

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [First embodiment] FIG. 1 is a block diagram showing a functional configuration of an electronic device 1 which is an information processing device (computer) of the first embodiment. The electronic device 1 is, for example, a wrist-worn terminal such as a smart watch or a portable terminal such as a smartphone, which moves with the user when the user goes out and allows the user to check the notification contents.

[0011] The electronic device 1 includes a CPU 11 (Central Processing Unit), a storage unit 12, an operation reception unit 13, a display unit 14, a communication unit 15, a clock unit 16, a satellite radio wave reception processing unit 17, and the like.

[0012] The CPU 11 is a hardware processor that performs arithmetic processing and controls the overall operation of the electronic device 1. The CPU 11 reads out and executes a program 121 from the storage unit 12. The control contents of the CPU 11 include a navigation operation that assists the movement of the user. There may be one or more CPUs 11. When there are multiple CPUs 11, they may operate in parallel for a certain process, or each may perform a different process independently. The multiple CPUs 11 may include CPUs that are each designed to be suitable for a specific purpose.

[0013] The storage unit 12 includes a volatile memory (RAM) and a non-volatile memory. The volatile memory provides a working memory space for the CPU 11 and stores temporary data. The non-volatile memory stores a program 121, setting data, and application data. The program 121 is a control program for control processing executed by the CPU 11. The control program includes a navigation control program (navigation application) related to the above navigation operation. The application data includes map data 122 used by the above navigation application.

[0014] The operation reception unit 13 receives an input operation from an external source such as a user, converts the operation content into an input signal, and outputs the input signal to the CPU 11. The operation reception unit 13 may include, for example, a push button switch and a touch panel.

[0015] The display unit 14 has a digital display screen, and displays on the digital display screen under the control of the CPU 11. The digital display screen is, for example, a liquid crystal display screen (LCD), but is not limited to this. The digital display screen may be positioned so as to overlap the above-mentioned touch panel.

[0016] The communication unit 15 controls communication with external devices via an Internet line, etc. Controllable communication standards are not particularly limited, but include, for example, various standards related to wireless LAN (Local Area Network).

[0017] The clock unit 16 holds the current date and time by counting a clock signal of a certain frequency that is output from an oscillator circuit (not shown).

[0018] The satellite radio wave reception processing unit 17 receives radio waves from positioning satellites related to the GNSS (Global Navigation Satellite System) and performs positioning calculations to perform satellite positioning (positioning) to identify the current position of the device. The satellite radio wave reception processing unit 17 has a first positioning unit 171 and a second positioning unit 172. Although not particularly limited, the first positioning unit 171 demodulates radio waves (first satellite signal, first radio signal) in the L1 band of the GPS (Global Positioning System), decodes the signal (navigation message), performs positioning calculations, and outputs the positioning result (first positioning result) to the CPU 11. The second positioning unit 172 demodulates radio waves (second satellite signal, second radio signal) in the L5 band of the GPS, decodes the signal (navigation message), performs positioning calculations, and outputs the positioning result (second positioning result) to the CPU 11. The first positioning unit 171 and the second positioning unit 172 are not particularly limited, but may be formed individually or collectively as a single module, and have an antenna, a receiving circuit (RF block) that extracts a signal, and a control circuit (baseband block) that includes a dedicated logic circuit and a CPU that demodulates, decodes, and performs positioning calculations to calculate the current position.

[0019] The format of navigation messages transmitted from GPS-related positioning satellites on L1 band radio waves is different from that of navigation messages transmitted on L5 band radio waves, and the latter has improved correction accuracy such as the accuracy of identifying the position of the positioning satellite. As a result, the positioning accuracy (L5 accuracy) of the result of positioning by reception in the L5 band (L5 positioning) is higher than the positioning accuracy (L1 accuracy) of the result of positioning by reception in the L1 band (L1 positioning), but the time required (at cold start) to decode the necessary navigation message and obtain the first positioning result is longer in the case of reception in the L5 band than in the case of reception in the L1 band.

[0020] In the satellite radio wave reception processing unit 17, the positioning by the first positioning unit 171 and the positioning by the second positioning unit 172 can be performed in parallel. When the first positioning unit 171 obtains a positioning result first and outputs this positioning result to the CPU 11, and then the second positioning unit 172 obtains a positioning result later, the satellite radio wave reception processing unit 17 changes the positioning result output to the CPU 11 to the positioning result by the second positioning unit 172. The satellite radio wave reception processing unit 17 outputs the positioning result to the CPU 11 with information that can identify which of the first positioning unit 171 and the second positioning unit 172 has output. Note that, when the L5 positioning result cannot be obtained (positioning has failed), the satellite radio wave reception processing unit 17 may return to outputting the L1 positioning result. Alternatively, the satellite radio wave reception processing unit 17 may continue to output both the L1 positioning result and the L5 positioning result to the CPU 11.

[0021] The electronic device 1 may also include other measurement sensors and / or annunciation units (not shown). The measurement sensors may include, for example, an acceleration sensor or a direction sensor (geomagnetic field sensor) for identifying the moving speed or the moving direction, and the annunciation unit may include, for example, a device that generates a beep or vibration to notify that the electronic device is proceeding normally or incorrectly along the navigation route.

[0022] Next, the navigation operation of this embodiment will be described. When the electronic device 1 acquires its own current position and the position of the destination, it performs a navigation operation, in which a suitable route from the current position to the destination is identified by referring to the map data 122, and navigation information (information using the positioning result) indicating the identified route on the map is generated and output. In the electronic device 1 of this embodiment, the navigation information is output to the display unit 14. The current position is obtained based on the positioning result by the satellite radio wave reception processing unit 17. The destination is determined, for example, by a user inputting an input operation on the touch panel of the operation acceptance unit 13, specifying a point on the map displayed on the display unit 14, or inputting numerical values ​​such as latitude and longitude information.

[0023] FIG. 2 is a diagram showing an example of a navigation display. When the destination G is set and the satellite radio wave receiving and processing unit 17 first obtains the current position S by the first positioning unit 171, the route indicated by the dashed line is specified. In the electronic device 1, navigation information displaying this route is generated, and the generated navigation information is output to and displayed on the display unit 14. At this time, the L1 accuracy is sufficient to identify the road, but may not be sufficient to meaningfully distinguish between the left and right sides of the road, and the navigation information (first information) generated based on the L1 positioning result has content according to the positioning accuracy of the positioning result, and indicates the center of the road along the route.

[0024] Thereafter, when the L5 positioning results start to be obtained at point P on the way of the user moving from the current position S to the destination G, the positioning accuracy increases to L5 accuracy, making it possible to distinguish between the left and right sides of the road, and it can be determined that the user is walking on the left side of the road. As a result, in the electronic device 1, the navigation information showing the route from point P to the destination G is switched to information (second information) based on the more accurate L5 positioning result and generated in accordance with the accuracy of the positioning result, and this can be output.

[0025] Here, the user holding the electronic device 1 is shown to continue along the sidewalk on the left side of the road, cross straight at the intersection with traffic lights N1 where a convenience store is located, turn left, and proceed along the right side of the road. After turning left at the intersection with traffic lights N1, there is no traffic light on the way to destination G, so by guiding the user to cross the road at the intersection with traffic lights N1 first, the user does not need to take the risk of crossing the road at a point without a traffic light or pass destination G and go to the next traffic light and then return.

[0026] That is, in the electronic device 1, navigation becomes possible from an early stage using the first positioning result obtained from the first positioning unit 171, and further, as long as the point P where the positioning result is obtained by the second positioning unit 172 is just before the signalized intersection N1, the positioning accuracy is improved even halfway through, making it possible to update to more preferable navigation information and provide it to the user.

[0027] FIG. 3 is a flowchart showing a control procedure by the CPU 11 of the navigation control process executed by the electronic device 1. This navigation control process includes an information processing method of the present invention, and is started, for example, when the CPU 11 acquires an input signal related to an operation to start up a navigation application, which is accepted by the operation acceptance unit 13.

[0028] When the navigation control process is started, the CPU 11 acquires a destination (step S101). For example, the CPU 11 causes the display unit 14 to display a map image on a digital display screen, and identifies and acquires the location of the destination indicated by a user's setting input operation.

[0029] The CPU 11 starts the satellite radio wave reception processing unit of the device itself (here, the satellite radio wave reception processing unit 17 of the electronic device 1) to start the positioning operation (step S102). Note that this processing may be performed in parallel with the processing of step S101 or prior to the processing of step S101.

[0030] The CPU 11 determines whether a new current position has been input from the satellite radio wave reception processing unit 17 to the CPU 11 (step S103). The new current position here refers to the current position input after the previous processing of step S103 (after the navigation control processing is started in the case of the first processing of step S103). The new current position may be the result of L1 positioning or the result of L5 positioning. If it is determined that a new current position has not been input to the CPU 11 ("NO" in step S103), the CPU 11 repeats the processing of step S103.

[0031] If it is determined that a new current position has been input to CPU 11 ("YES" in step S103), CPU 11 acquires the input new current position (step S104; first acquisition means, second acquisition means, first acquisition step, second acquisition step). CPU 11 determines whether it is before the start of acquisition of the L5 positioning result by second positioning unit 172 and whether what has been acquired is the result of L1 positioning (step S105). If it is determined that it is before the start of acquisition of the L5 positioning result ("YES" in step S105), CPU 11 specifies a route based on the accuracy of L1 positioning and creates navigation information (step S106). Then, the processing of CPU 11 proceeds to step S108.

[0032] If it is determined in the determination process of step S105 that the acquisition of the result of L5 positioning has started and the result of L5 positioning has been acquired ("NO" in step S105), the CPU 11 specifies a route based on the accuracy of the L5 positioning and creates navigation information (step S107). Then, the process of the CPU 11 proceeds to step S108.

[0033] When the process proceeds from step S106 and step S107 to step S108, the CPU 11 updates the content to be displayed on the display unit 14 based on the navigation information (step S108). The CPU 11 determines whether the user has arrived at the destination, i.e., whether the current position coincides with the destination (within a predetermined distance) (step S109). If it is determined that the user has not arrived at the destination ("NO" in step S109), the process of the CPU 11 returns to step S103. If it is determined that the user has arrived at the destination ("YES" in step S109), the CPU 11 ends the navigation control process. Among the above processes, the processes in steps S106 to S108 form the output means (output step in the information processing method) of the present invention.

[0034] [Second embodiment] Next, a second embodiment of the present invention will be described, which is operated by an information processing system using a plurality of electronic devices. FIG. 4 is a diagram illustrating the functional configuration of the information processing system 100 according to the present embodiment. The information processing system 100 includes the above-mentioned electronic device 1 as an external device, and an electronic device 4 which is an information processing device (computer) of this embodiment.

[0035] The electronic device 4 is not limited to a portable device, but may be a navigation device attached to a specific moving object, such as a taxi in this case. The electronic device 1 here is a portable device carried by a taxi user or a person who drives the user to and from the taxi pick-up location.

[0036] The electronic device 4 includes a CPU 41 (a first processing unit in this embodiment), a storage unit 42, an operation acceptance unit 43, a display unit 44, a communication unit 45 (a first communication unit in this embodiment), a clock unit 46, and a satellite radio wave reception processing unit 47. The CPU 41, the storage unit 42 that stores a program 421 and map data 422, the operation acceptance unit 43, the display unit 44, the communication unit 45, and the clock unit 46 have the same functional configurations as the CPU 11, the storage unit 12, the operation acceptance unit 13, the display unit 14, the communication unit 15, and the clock unit 16, respectively, and therefore detailed explanations thereof will be omitted. Note that the functional configuration referred to here does not include differences in specific performance (e.g., the operating frequency of CPU 11, 41, the memory type and memory capacity of memory units 12, 42, the number of pixels and brightness value of display units 14, 44, the reception efficiency of satellite radio wave reception processing unit 47, etc.) and operation type (the operating system (OS) related to the processing of CPU 41 and the reception device of operation reception unit 43, etc.). The communication unit 45 is capable of communicating with the electronic device 1 via the Internet or the like.

[0037] Satellite radio wave reception processing unit 47 differs from satellite radio wave reception processing unit 17 in that it receives only L1 band radio waves and performs positioning. In this embodiment, first positioning unit 171 of satellite radio wave reception processing unit 17 corresponds to a third positioning unit in the present invention that receives a third radio signal (L1 band radio waves) and performs positioning, and second positioning unit 172 corresponds to a fourth positioning unit in the present invention that receives a fourth radio signal (L5 band radio waves) and performs positioning.

[0038] In this information processing system 100, the electronic device 4 acquires positioning information from the electronic device 1 and performs navigation with a destination determined according to the positioning information. For example, the program 421 of the electronic device 4 includes a taxi dispatch program used by taxi drivers, and the program 121 of the electronic device 1 includes a taxi dispatch request application used by taxi users (passengers, etc.).

[0039] When the dispatch request app of the electronic device 1 is executed by the CPU 11 (second processing unit in this embodiment) and a dispatch request operation is performed, first, current location information based on L1 positioning by the first positioning unit 171 is directly transmitted and output from the satellite radio wave reception processing unit 17 of the electronic device 1 to the server of the dispatch center or the electronic device 4 by the communication unit 15 (second communication unit in this embodiment), and then current location information based on L5 positioning by the second positioning unit 172 is transmitted and output by the communication unit 15 to the server of the dispatch center or the electronic device 4. When transmitting current location information, the electronic device 1 includes information on the type of radio signal received when acquiring the current location information, or at least information on the accuracy, in the transmission data.

[0040] When the information on the current location is transmitted to the server of the dispatch center, a taxi to be sent to the location of the electronic device 1 is determined based on the location information of multiple taxis acquired in real time and the current location information of the electronic device 1 with L1 accuracy that has been requested to be dispatched, and the request for dispatch and the location of the electronic device 1 are transmitted to the electronic device 4 of the taxi. When the electronic device 4 acquires a request for dispatch from the dispatch center or the electronic device 1 through the communication unit 45, the electronic device 4 specifies a route to the location of the electronic device 1 based on its own current location and the location of the electronic device 1, generates navigation information, and causes the display unit 44 to display the navigation information. At this time, when location information with L5 accuracy is acquired with a delay from the initial location information with L1 accuracy as the location of the electronic device 1, location information such as which side of the road the electronic device 1 is on can be specified, and it is therefore possible to specify which lane the taxi should take to arrive at the location.

[0041] FIG. 5 is a diagram showing an example of a display screen of a vehicle dispatch navigation (car navigation) in the electronic device 4. As shown in FIG. The traveling direction (body orientation) of the taxi at the current position may be determined by other measurement sensors, etc. In addition, although the map is fixedly displayed with north facing upward here, the map may be rotated so that the traveling direction of the taxi is the upward direction of the map.

[0042] The route from the current position S of the taxi to the position of the electronic device 1, which is the destination G, branches at a branch point N2 into a route shown by a solid line and a route shown by a dotted line, depending on the lane of the destination G. While the positioning information with L1 accuracy is being acquired, only one of these routes may be displayed, or both routes may be displayed, but it is preferable that the branch point N2 is displayed so that the taxi driver can reliably know it.

[0043] If location information with L5 accuracy is acquired before reaching the branch point N2 and the location of the electronic device 1 (destination G) is specified more accurately, the electronic device 4 selects one of the routes according to the information and switches to displaying only one of the routes. If location information with L5 accuracy is unlikely to be acquired (if it has not been acquired) before reaching the branch point N2, the taxi driver who knows the branch point N2 can wait in front of the branch point N2. Alternatively, the taxi driver may proceed along one of the routes without waiting in front of the branch point N2, and when location information with L5 accuracy is acquired thereafter, the optimal route at that time is identified and displayed based on the acquired information.

[0044] FIG. 6 is a flowchart showing a control procedure of the navigation control process executed by the CPU 41 in the electronic device 4. This navigation control process includes other information processing methods of the present invention, and is started when a dispatch request is received from a taxi dispatch center or the electronic device 1. In this process, the processes of steps S101 and S106 in the navigation control process of the first embodiment shown in Fig. 3 are changed to steps S101a and S106a, respectively, and steps S111 to S115 are added. The other processes are the same, and the same process contents are denoted by the same reference numerals and detailed explanations are omitted.

[0045] When the navigation control process is started, the CPU 41 acquires the location information of the destination with L1 accuracy from the device related to the dispatch request (step S101a; first acquisition means). Then, the process of the CPU 41 proceeds to step S102, where it activates the satellite radio wave reception processing unit of its own device (here, the satellite radio wave reception processing unit 47 of the electronic device 4) to start the positioning operation (step S102).

[0046] If it is determined in the determination process of step S103 that a new current position has been input ("YES" in step S103), the CPU 41 acquires the input current position (step S104), identifies a travel route based on the acquired current position and the acquired destination (the position of the electronic device 1), and generates navigation information (step S106a). If the destination is not obtained with L5 accuracy, the CPU 41 considers the case where the road at the destination has multiple lanes as described above (or determines from the map data 122, as necessary) and identifies a travel route for each of the directions of both lanes. Then, the process of the CPU 41 proceeds to step S111. If it is determined that a new current position has not been input ("NO" in step S103), the process of the CPU 41 proceeds to step S111.

[0047] When the process proceeds to step S111, the CPU 41 determines whether or not destination information with L5 accuracy has been input from the electronic device 1 to the CPU 41 via the communication unit 45 (step S111). If it is determined that destination information has been input to the CPU 41 ("YES" in step S111), the CPU 41 acquires destination data and updates the destination data that had L1 accuracy to L5 accuracy using the acquired data (step S112; second acquisition means). The CPU 41 determines whether or not the current position has been acquired at least once (step S113). If it is determined that the current position has not been acquired (has never been acquired) ("NO" in step S113), the process of the CPU 41 returns to step S103.

[0048] If it is determined that the current location has been acquired at least once ("YES" in step S113), the CPU 41 identifies a route to the destination based on the updated destination and the current location, and generates navigation information indicating this route (step S114). If the navigation information generated in step S105a has not been displayed, the CPU 41 may simply overwrite and update the undisplayed navigation information. Then, the processing of the CPU 41 proceeds to step S115.

[0049] When it is determined in the determination process of step S111 that destination information with L5 accuracy has not been acquired ("NO" in step S111), the process of the CPU 41 proceeds to step S115.

[0050] When the process proceeds from steps S111 and S114 to step S115, the CPU 41 determines whether the navigation information has been updated, that is, whether there is any undisplayed navigation information (step S115). If it is determined that the navigation information has been updated ("YES" in step S115), the process proceeds to step S107. If it is determined that the navigation information has not been updated ("NO" in step S115), the process returns to step S103. In this embodiment, among the above-mentioned processes, the processes of steps S106a, S114, and S108 constitute the output means of the present invention.

[0051] 7 is a flowchart showing a control procedure by the CPU 11 of the vehicle dispatch request control process executed by the electronic device 1. This vehicle dispatch request control process is started, for example, when a taxi dispatch request application is started.

[0052] The CPU 11 activates the satellite radio wave reception processing unit 17 to start a positioning operation (step S201). The CPU 11 acquires vehicle dispatch request information based on an input operation to the operation reception unit 13 (step S202). The vehicle dispatch request information may include, for example, a requester's name or requester identification information, requested information on the size or type of vehicle or information on the number of passengers planned to board, information on a designated time from the transmission of the request to the actual dispatch or information on the dispatch request date and time, and / or information on a planned drop-off location. The vehicle dispatch request information may include an initial setting or a setting that is preset by a user and stored in the storage unit 12.

[0053] The CPU 11 determines whether or not current location information based on L1 positioning has been input from the satellite radio wave reception processing unit 17 to the CPU 11 (step S203). If it is determined that current location information based on L1 positioning has not been input to the CPU 11 ("NO" in step S203), the CPU 11 repeats the process of step S203. If it is determined that current location information based on L1 positioning has been input to the CPU 11 ("YES" in step S203), the CPU 11 acquires the input current location information based on L1 positioning (step S204).

[0054] The CPU 11 sets the current location (L1) as the boarding location, and transmits the dispatch request together with the current location (L1) and the dispatch request information via the communication unit 15 (step S205). The transmission destination is the server of the dispatch center or the navigation device of a specific taxi (electronic device 4) as described above, and the current location by this L1 positioning is the first positioning result in the electronic device 4. At this time, unique identification information is attached to the dispatch request.

[0055] The CPU 11 determines whether or not the current location information by the L5 positioning has been input from the satellite radio wave reception processing unit 17 to the CPU 11 (step S206). If it is determined that the current location information by the L5 positioning has not been input to the CPU 11 ("NO" in step S206), the CPU 11 repeats the process of step S206.

[0056] If it is determined that the current location information obtained by L5 positioning has been input to the CPU 11 ("YES" in step S206), the CPU 11 acquires the input current location information obtained by L5 positioning (step S207). The CPU 11 causes the communication unit 15 to transmit the current location information obtained by L5 positioning as update information for the boarding location together with the identification information of the already-transmitted dispatch request (step S208). This current location obtained by L5 positioning is the second positioning result in the electronic device 4. Then, the CPU 11 ends the dispatch request control process. Among the above processes, the processes in steps S205 and S208 constitute the control means in the information processing system of the present invention.

[0057] [Third embodiment] An information processing system 100a according to the third embodiment will be described. FIG. 8 is a diagram illustrating the functional configuration of an information processing system 100a according to the third embodiment. The information processing system 100a includes electronic devices 1 and 4a. The electronic device 4a is, for example, a navigation device for a taxi or the like, similar to the electronic device 4 in the second embodiment, and constitutes an information processing device (computer) of this embodiment. The electronic device 4a includes a satellite radio wave reception processing unit 47a instead of the satellite radio wave reception processing unit 47 in the electronic device 4 in the second embodiment. The satellite radio wave reception processing unit 47a has a first positioning unit 471 that receives radio waves in the L1 band and a second positioning unit 472 that receives radio waves in the L5 band. The other configurations are the same between the electronic device 4 and the electronic device 4a, and the same configurations are denoted by the same reference numerals and detailed description thereof will be omitted.

[0058] In the information processing system 100a, the first positioning unit 171 of the electronic device 1 serves as a third positioning unit and receives radio waves (third radio signal) in the L1 band, and the second positioning unit 172 serves as a fourth positioning unit and receives radio waves (fourth radio signal) in the L2 band. Therefore, the positioning accuracy of each of the electronic devices 1 and 4a switches from L1 accuracy to L5 accuracy midway. In the electronic device 4a, the CPU 41 as a first processing unit acquires the positioning result of the first positioning unit 471 as the first positioning result, and acquires the positioning result of the second positioning unit 472 as the second positioning result. In addition, the CPU 41 acquires the positioning result of the first positioning unit 171 transmitted and output by the communication unit 15 from the electronic device 1 as the third positioning result via the communication unit 45, and acquires the positioning result of the second positioning unit 172 transmitted and output by the communication unit 15 from the electronic device 1 as the fourth positioning result via the communication unit 45.

[0059] Furthermore, the electronic device 4a can acquire the congestion status of the road and reflect it in the specification of the route. At this time, if the position information is obtained with L5 accuracy, the lane may be considered based on the congestion information. The lane here includes multiple lanes in the same direction such as a right turn lane and a left turn lane, and for example, a route may be set in which the position for turning right / left is changed according to the congestion information of each lane.

[0060] Furthermore, in the navigation operation of the electronic device 4, it is not limited to determining whether to turn right or left based on the congestion situation, but it may also be possible to notify in advance when turning right or left, and to determine whether or not the vehicle is actually in an appropriate lane before actually turning right or left, and have the display unit 44 and / or the notification operation unit issue a warning.

[0061] FIG. 9 is a flowchart showing a control procedure by the CPU 41 of the navigation control process executed by the electronic device 4a of the information processing system 100a. In the navigation control process of the third embodiment including another information processing method of the present invention, a process of step S131 is added to a combination of steps S102 to S109 in the navigation control process of the first embodiment shown in Fig. 3 and steps S101a and S111 to S114 in the navigation control process of the second embodiment shown in Fig. 6. A detailed description of the same processes as those already explained will be omitted.

[0062] In this navigation control process, when it is determined in the determination process of step S103 that a new current position has been input ("YES" in step S103), the CPU 41 acquires information on road congestion from the outside (step S131; road condition acquisition means). The information on road congestion may be received, for example, from an external road information providing server via the communication unit 45. Then, the process of the CPU 41 proceeds to step S104.

[0063] The acquired information on road congestion is used in the process of specifying a route and generating navigation information in steps S106, S107, and S114. In the process of steps S106 (and S114), a route may be selected depending on the current position and the destination position with L1 accuracy. In the process of steps S107 and S114, a route and a lane may be selected depending on the current position and / or the destination position with L5 accuracy. In the information processing system 100a of this embodiment, step S104 constitutes the first and second acquisition means of the present invention, step S101a constitutes the third acquisition means of the present invention, and step S112 constitutes the fourth acquisition means of the present invention. Also, the processes of steps S106, S107, S114, and S108 constitute the output means of the present invention. In step S106, the information generated when the current position and the destination are both obtained with L1 accuracy is the third information, and the information generated when the current position is obtained with L1 accuracy and the destination is obtained with L5 accuracy is the fifth information. In step S107, the information generated when the current position is obtained with L5 accuracy and the destination is obtained with L1 accuracy is the fourth information, and the information generated when both the current position and the destination are obtained with L5 accuracy is the sixth information. In step S114, the information generated when the current position is obtained with L1 accuracy and the destination is obtained with L5 accuracy is the fifth information, and the information generated when both the current position and the destination are obtained with L5 accuracy is the sixth information. The third information to the sixth information are different from each other.

[0064] As described above, the electronic device 1, which is the information processing device of this embodiment, includes the CPU 11 as a first processing unit. The CPU 11 acquires a first positioning result (here, the result of L1 positioning) (step S101a in FIG. 6, S104 in FIG. 3), acquires a second positioning result (here, the result of L5 positioning) with higher positioning accuracy than the first positioning result (step S112 in FIG. 6, S104 in FIG. 3), generates information using the acquired positioning result, and outputs the information. When the first positioning result has been acquired, the CPU 11 as a first processing unit generates first information based on the first positioning result, the contents of which correspond to the first positioning result (step S106), and when the second positioning result has been acquired, generates second information based on the second positioning result, the contents of which correspond to the second positioning result, different from the first information (step S107). In this way, when two types of positioning results with different accuracies can be obtained, if the first positioning result with lower accuracy is obtained first, information is generated with the accuracy possible from this first positioning result and output, so that the user who wants the information can make a provisional decision or take an action without having to wait a long time until the second positioning result is obtained. After that, as soon as the second positioning result is obtained, information with higher accuracy is switched to and output, so that the user can narrow down their decision based on the more accurate position or improve the accuracy of their action. Therefore, the electronic device 1 can provide a service that is more convenient for the user by using the positioning information.

[0065] In addition, the first positioning result is obtained by satellite positioning performed by receiving a first satellite signal (GPS L1 band radio waves), and the second positioning result is obtained by satellite positioning performed by receiving a second satellite signal (GPS L5 band radio waves) different from the first satellite signal. Providing information based on positioning results using radio waves from satellites (particularly positioning satellites) is highly convenient for users because it can be widely used outdoors. On the other hand, since it takes time to obtain the necessary parameters from data transmitted according to a predetermined format and obtain the positioning results, by providing provisional information at the stage when the information is obtained, even if the accuracy is slightly lower than that of the final information, the time that the user has to wait without obtaining the information can be shortened.

[0066] The information to be output is navigation information indicating a route between the current position of the device itself (for example, the electronic device 1) and the destination. With navigation information, while waiting without obtaining information is a waste of time, a user can start moving even if there is not necessarily high-precision position information at the time of departure. Therefore, providing information in two stages, in which low-precision position information is provided immediately and then high-precision information is provided, is particularly convenient for the user.

[0067] Furthermore, when the second positioning result is obtained, the CPU 11 as the first processing unit generates navigation information by distinguishing between the left and right sides of the road. In navigation in towns and the like, it is often not easy to cross roads or reverse direction, so by distinguishing between the left and right sides of the road and determining a more appropriate travel route, the usefulness of navigation can be further improved.

[0068] Moreover, the electronic device 4 of the second embodiment includes a communication unit 45 that communicates with an external device. The CPU 41 as the first processing unit may acquire the positioning results of the destination from the electronic device 1, which is the external device, through the communication unit 45 (steps S101a and S112 in FIG. 6), and generate navigation information based on the positioning results. That is, even when the destination is determined by sequentially acquiring, as the positioning information from the external device, low-precision positioning information in which the time required from the start of radio wave reception to acquiring the positioning result is relatively short, and high-precision positioning information in which the time required is long, the waiting time until the start of movement can be shortened and the accuracy of the arrival position and route to the destination can be improved as described above, and the electronic device 1 can improve the convenience of the user.

[0069] Alternatively, like the electronic device 1 of the first embodiment, the electronic device may include a first positioning unit 171 that receives a first radio signal (radio waves in the L1 band) and performs positioning, and a second positioning unit 172 that receives a second radio signal (radio waves in the L5 band) and performs positioning with higher positioning accuracy than the first positioning unit 171. The CPU 11 as a first processing unit acquires the positioning result of the first positioning unit 171 as the first positioning result, and acquires the positioning result of the second positioning unit 172 as the second positioning result (above, step S104), and generates navigation information from the current position indicated by the acquired positioning results to the destination (step S107). When satellite positioning is performed by the device itself, it is easy to generate and output information that appropriately reflects the positioning results and their accuracy. In this case, navigation operations can be performed independently without communication with external devices, so the configuration for providing information does not need to be large-scale.

[0070] Furthermore, the CPU 11 as the first processing unit distinguishes the lanes of the road based on the acquired second positioning result, and generates navigation information including the lanes according to the traveling direction. In the case of vehicle navigation, there are many roads where the lanes differ depending on the traveling direction, and the lane position on the opposite side of the destination may not be sufficient as the arrival position. Therefore, by making it possible to provide information so that the user can finally arrive at the appropriate lane position based on the highly accurate current position and destination information, the convenience of the user can be improved.

[0071] In addition, in the electronic device 4a of the third embodiment, the CPU 41 as the first processing unit acquires the congestion status for each lane of a road and generates navigation information taking the acquired congestion status into consideration. Conventionally, it has been possible to deal with overall congestion due to road closures or the closure of some lanes, but by making it possible to distinguish between individual lanes, it is possible to selectively determine partial congestion, such as in right-turn / left-turn lanes, and to provide information that is more convenient for the user.

[0072] Furthermore, when the second positioning result has not been acquired, and there is a branch point of multiple routes to be selected according to the second positioning result, the CPU 11 as the first processing unit generates navigation information capable of identifying the branch point. That is, if the vehicle proceeds in a wrong direction beyond the branch point, it may be found that the route will be longer or take more time when highly accurate information is obtained, so it may be possible to temporarily move to a point where there is no problem. If highly accurate information is obtained before arriving at the branch point, no problem will occur and the time required for dispatching will be shortened, and even if highly accurate information is not obtained before arriving at the branch point, the time required to arrive at the destination point can be shortened by waiting in the vicinity of the branch point, for example.

[0073] Furthermore, when the second positioning result is not acquired, the CPU 11 as the first processing unit may generate navigation information indicating each of a plurality of routes to be selected according to the second positioning result. Regardless of the above, both routes after the branch point may be displayed in parallel, or a plurality of routes with similar arrival times that may vary depending on congestion conditions may be displayed in parallel. When low-precision location information is sufficient without the need to acquire high-precision location information, for example, when the lanes at the destination are not separated or it is easy to turn around on site, and it does not matter which direction the destination is actually in, routes in both directions may be displayed in parallel. Furthermore, when the program 121 can determine a more appropriate route based on the map data 122, the routes to be displayed in parallel may be prioritized.

[0074] Moreover, the information processing system 100 of the present embodiment includes an electronic device 4 and an electronic device 1 as an external device. The electronic device 1 includes a first positioning unit 171 that receives a third radio signal (radio waves in the L1 band) and performs positioning, a second positioning unit 172 that receives a fourth radio signal (radio waves in the L5 band) and performs positioning with a higher positioning accuracy than the first positioning unit 171, a communication unit 15, and a CPU 11 as a second processing unit that, when a positioning result is obtained by the first positioning unit 171 (step S204 in FIG. 7), causes the communication unit 15 to output the positioning result to the electronic device 4 as a first positioning result (step S205 in FIG. 7), and, when a positioning result is obtained by the second positioning unit 172 (step S207 in FIG. 7), causes the communication unit 15 to output the positioning result to the electronic device 4 as a second positioning result (step S208 in FIG. 7). In this way, by sequentially obtaining positioning data of two different degrees of accuracy from an external device, the technology improves the accuracy of the output information using the positioning results, making it possible to start providing information to the user of electronic device 4 promptly, and to provide more accurate information as soon as possible, thereby improving convenience for the user.

[0075] Moreover, the information processing system 100a of this embodiment includes first positioning units 171, 471 that receive radio waves in the L1 band in the electronic device 4a as an information processing device and the electronic device 1 as an external device, and second positioning units 172, 472 that receive radio waves in the L5 band. The electronic devices 4a, 1 include communication units 45, 15 for communicating with each other, and the positioning results of the first positioning unit 171 and the second positioning unit 172 output from the electronic device 1 by the communication unit 15 are received and acquired by the electronic device 4a through the communication unit 45. In the electronic device 4a, when the first positioning result and the third positioning result are acquired, third information having contents corresponding to the positioning accuracy of the first positioning result and the positioning accuracy of the third positioning result is generated based on the first positioning result and the third positioning result, and when the second positioning result and the third positioning result are acquired, fourth information having contents corresponding to the positioning accuracy of the second positioning result and the positioning accuracy of the third positioning result is generated based on the second positioning result and the third positioning result. When the first positioning result and the fourth positioning result are acquired, the fifth information is generated based on the first positioning result and the fourth positioning result, the fifth information has contents corresponding to the positioning accuracy of the first positioning result and the positioning accuracy of the fourth positioning result, respectively. When the second positioning result and the fourth positioning result are acquired, the sixth information is generated based on the second positioning result and the fourth positioning result, the sixth information has contents corresponding to the positioning accuracy of the second positioning result and the positioning accuracy of the fourth positioning result, respectively. The third information to the sixth information are different from each other. That is, the electronic device 4a starts outputting information based on the initially acquired positioning data of the first positioning units 171 and 471 (step S106 in FIG. 9), and as soon as at least one of the positioning data of the second positioning units 172 and 472 is acquired, the accuracy of the output information is sequentially improved (steps S107 and S114 in FIG. 9). Even in such a case, convenience for the user can be improved by promptly starting to provide information to the user of the electronic device 4a and providing more accurate information as soon as possible.

[0076] Furthermore, the information processing method of this embodiment includes a first acquisition step of acquiring a first positioning result, a second acquisition step of acquiring a second positioning result having a higher positioning accuracy than the first positioning result, and an output step of generating information using the acquired positioning result and outputting the information, in which, in the output step, when the first positioning result has been acquired, first information having content corresponding to the positioning accuracy of the first positioning result is generated based on the first positioning result, and when a second positioning result has been acquired, the output step switches to generating second information having content corresponding to the positioning accuracy of the second positioning result, different from the first information, based on the acquired second positioning result. In this way, when two types of positioning results with different accuracies can be obtained, if the first positioning result with lower accuracy is obtained first, information is output within the range of accuracy possible with this first positioning result, so that the user who wants the information (the information recipient) can make a provisional decision or action without having to wait a long time until the second positioning result is obtained. After that, as soon as the second positioning result is obtained, information with higher accuracy is switched to and output, so that the user can narrow down their decision based on the more accurate position or improve the accuracy of their action. Therefore, such an information processing method can improve the convenience of the user in relation to services using positioning information.

[0077] In addition, the program 121 of this embodiment causes a computer (electronic device 1, 4, 4a) to function as a first acquisition means for acquiring a first positioning result, a second acquisition means for acquiring a second positioning result having a higher positioning accuracy than the first positioning result, and an output means for generating information using the acquired positioning result and outputting the information, and when the first positioning result has been acquired, the output means generates first information based on the first positioning result, the content of which corresponds to the positioning accuracy of the first positioning result, and when the second positioning result has been acquired, generates second information based on the acquired second positioning result, the content of which is different from the first information and corresponds to the positioning accuracy of the second positioning result. By installing such a program 121, it becomes possible to easily perform the process of acquiring positioning data of two different levels of accuracy and outputting the information, and thus it is possible to easily provide services that utilize positioning information with improved user convenience in general-purpose electronic devices, etc.

[0078] The present invention is not limited to the above-described embodiment, but may be modified in various ways. For example, when the current position of the vehicle is identified by the positioning of the vehicle itself in the above two steps, if the destination is also acquired from an external device, the external device is not limited to transmitting the positioning result, and may transmit information input by the user, etc. In this case, if additional information is acquired by the response of an operator at the vehicle dispatch center, more accurate information may be acquired.

[0079] In the above embodiment, the case where navigation information is generated and output is described as an example, but the present invention is not limited to this as long as the service provides information using the positioning result. For example, the present invention may be a service that provides store information, traffic information, parking information, etc. near the current position or destination where the positioning result is obtained, or a service that simply records a log of the movement trajectory.

[0080] In the above embodiment, the case where GPS radio waves in the L1 band and L5 band are received and positioning is performed respectively has been described, but the present invention is not limited to this as long as the same condition is satisfied, that is, the positioning result of the lower-precision side of the two types of positioning is often obtained first, and the positioning result of the higher-precision side is obtained later. Other satellite positioning systems, for example, radio waves transmitted from positioning satellites such as GLONASS and Galileo, may be used. This is not limited to radio waves of multiple wavelengths from the same positioning satellite. Positioning results may also be obtained using radio waves other than those of a positioning satellite. For example, the approximate position may be obtained early by communication with a mobile phone antenna.

[0081] In addition, in the above embodiment, navigation by a smartphone or smartwatch has been described as targeting pedestrians, but it may also be possible to target bicycles, etc., and switching may be performed in response to user input operations, or automatically by determining the previous movement state, etc., using a sensor, etc.

[0082] In addition, the output target is not limited to the display screen of the own device. For example, a user who uses both a smartphone and a smartwatch may display an output image of the smartphone on the display screen of the smartwatch, or vice versa.

[0083] In addition, for example, when the second (L5 band) radio waves are acquired almost simultaneously with or before the first (L1 band) radio waves, including cases such as a warm start or hot start, processing may be selected so that information based on L5 positioning is generated from the beginning.

[0084] In addition, in the above embodiment, it has been explained that two types of routes may be identified and their branching points may be displayed in a knowable manner until the second positioning result is obtained, but if there is a waiting location before the branching point, the waiting location may also be output.

[0085] Furthermore, the configurations, processing contents, and procedures shown in the above three types of embodiments can be arbitrarily combined or deleted as long as there is no contradiction or inconsistency.

[0086] In the above description, the storage units 12, 42 made of nonvolatile memory such as flash memory are used as computer-readable media for storing the programs 121, 421 related to the navigation control of the present invention, but the present invention is not limited to this. As other computer-readable media, other nonvolatile memories such as HDD (Hard Disk Drive) and MRAM, and portable recording media such as CD-ROM and DVD disks can be used. In addition, a carrier wave is also applied to the present invention as a medium for providing data of the program according to the present invention via a communication line. In addition, the specific configurations, contents and procedures of the processing operations, etc. shown in the above embodiments can be modified as appropriate without departing from the spirit of the present invention.
