[Figure 7] This flowchart shows an example of the operation of the information processing device according to this embodiment. [Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described below with reference to the drawings. In all drawings, similar components are denoted by the same reference numerals, and their descriptions are omitted where appropriate.

[0010] [First Embodiment] Figure 1 is a diagram showing an overview of the information processing device 10 according to this embodiment, along with its usage environment. The information processing device 10 is used, for example, together with an input device 20 and an output device 30. The input device 20 and the output device 30 may both be part of the information processing device 10, or they may be separate devices. In the latter case, these devices communicate with the information processing device 10 at least when the information processing device 10 is in use. An example of the information processing device 10 is a vehicle navigation system. Alternatively, the information processing device 10 may be a mobile terminal such as a smartphone owned by the user, with a predetermined application installed.

[0011] Furthermore, the input device 20 is a device that acquires input from the user. The input device 20 may acquire user input, for example, by voice, or it may acquire user input by displaying a screen and operating the screen. The output device 30 is a device that outputs to the user. The output device 30 may output to the user by voice or sound, or it may display a screen to the user. Details of the output to the user by the output device 30 will be described later.

[0012] Vehicles include, but are not limited to, automobiles, motorcycles, and mopeds. In the following explanation, unless otherwise specified, vehicles will be described as automobiles.

[0013] Next, as shown in FIG. 1, the information processing apparatus 10 includes an acquisition unit 100, a generation unit 200, an output unit 300, and a storage unit 400. However, the storage unit 400 may be included inside the information processing apparatus 10 or may be provided externally. Also, the storage unit 400 may be divided into a plurality of parts. The storage unit 400 may be configured, for example, by a combination of a storage provided in the information processing apparatus 10 and an external server capable of communicating with the information processing apparatus 10. Hereinafter, the details of each configuration will be described.

[0014] [Acquisition Unit 100] The acquisition unit 100 acquires first route information indicating a first route from a reference position to a destination and second route information indicating a second route that is different from the first route and by which the vehicle reaches the destination from the reference position. The route from the reference position to the destination that the user actually travels is the first route. And the route from the reference position to the destination that is different from the first route is the second route.

[0015] As an example, at least one of the first route and the second route is a route proposed by a route search device such as a navigation system. For example, when traveling from a reference position to a destination, assume that a plurality of routes are proposed by the route search device. In this case, among the plurality of proposed routes, the selected (actually traveled) route is the first route, and the unselected route is the second route. Note that the second route may be specified by the user's manual input. Also, there may be a plurality of second routes. For example, when three or more routes are proposed by the route search device, two or more unselected routes are the second routes.

[0016] Further, the acquisition unit 100 acquires performance information indicating the driving performance generated by the vehicle actually traveling along the first route from the reference position to the destination. Details of the driving performance will be described later.

[0017] [Generation Unit 200] The generation unit 200 generates estimated information showing the estimated driving results assuming that the vehicle traveled along the second route acquired by the acquisition unit 100. The specific method by which the generation unit 200 generates the estimated information will be described below.

[0018] <Example 1 of a method for generating estimated information> The generation unit 200 acquires information indicating the driving record of other vehicles when they actually travel the second route, and generates estimated information based on the acquired information. In the following description, the vehicle using the information processing device 10 according to this embodiment will be referred to as "this vehicle" when referring to other vehicles. The generation unit 200 may, for example, directly communicate with other vehicles to acquire information indicating the driving record of other vehicles when they actually travel the second route, or it may acquire information indicating the driving record of other vehicles when they actually travel the second route via a network.

[0019] Furthermore, it is preferable that the generation unit 200 generates estimated information using the driving records of other vehicles that traveled at least a portion of the second route at the same time that the vehicle traveled the first route. In this case, the driving records of the vehicle that actually traveled the first route can be compared with the driving records of the vehicle that would have traveled the second route under more equal conditions. The driving records of other vehicles can be read, for example, from an external server that constitutes the storage unit 400.

[0020] Furthermore, the "driving records of other vehicles that traveled at least a portion of the second route" mentioned above also include, for example, the driving records for each link between nodes such as intersections and other junctions in the road network representation of the second route. The generation unit 200 may generate estimated information based on the driving records of other vehicles that traveled the entire second route at the same time as the vehicle traveled the first route, or it may generate estimated information by combining the driving records of at least one other vehicle that traveled each link of the second route at the same time as the vehicle traveled the first route. For example, if the second route includes four consecutive links from the first to the fourth link, the estimated information may be generated using the driving records of the first other vehicle that traveled the first link, the second other vehicle that traveled the second link, the third other vehicle that traveled the third link, and the fourth other vehicle that traveled the fourth link. Furthermore, from the perspective that it is preferable to use driving records of the same vehicle traveling consecutively as much as possible, for example, if the first other vehicle travels on the first, second, and third links, but not on the fourth link, the driving records of the first other vehicle that traveled consecutively on the first, second, and third links may be used to generate the estimated information, while the driving records of the fourth other vehicle may be used only for the fourth link.

[0021] Furthermore, if there are multiple other vehicles that traveled at least part of the second route, the travel record of the other vehicle that traveled at the time closest to the time the vehicle in question traveled the first route may be used, or the average value of the travel records of multiple other vehicles may be used.

[0022] The above date and time refers to a predetermined time period, not a specific moment, such as a time period of 1 hour or more but 3 hours or a time period of 30 minutes or more but 1 hour. In other words, "the vehicle traveled the entirety of Route 2 at the same time and date as it traveled Route 1" includes the vehicle traveling the entirety of Route 2 during the same time period as it traveled Route 1.

[0023] However, if estimation information cannot be obtained based on the driving records of other vehicles that traveled at least a portion of the second route at the same time as the vehicle that traveled the first route (for example, if driving records for some links of the second route cannot be obtained at the same time as the vehicle that traveled the first route), estimation information may be generated using the driving records of other vehicles that traveled at least a portion of the second route at a different time on the same day that the vehicle traveled the first route, or at the same time on a different day that the vehicle traveled the first route. However, even in this case, it is preferable to use the driving records of other vehicles that traveled at least a portion of the second route under conditions as close as possible to the time the vehicle traveled the first route. For example, if the day the vehicle traveled the first route is a weekday, it is preferable to use the driving records of other vehicles that traveled at least a portion of the second route at the same time on another weekday, and if the day the vehicle traveled the first route is a public holiday, it is preferable to use the driving records of other vehicles that traveled at least a portion of the second route at the same time on another public holiday.

[0024] Furthermore, it is preferable that the driving records of other vehicles used to generate the estimated information be those of the same vehicle type as the vehicle in question. Here, vehicle type refers to classifications such as large vehicles, passenger cars, motorcycles, and commercial vehicles. In this case, the storage unit 400 stores information indicating the vehicle type in association with the driving records.

[0025] Figure 2 is a flowchart showing the flow of the first example of the method for generating the estimated information described above. First, the acquisition unit 100 acquires second route information indicating the second route (step S10).

[0026] Next, the generation unit 200 determines whether there is a record of other vehicles traveling the entire second route at the time the vehicle traveled (step S20). If there is a record of other vehicles traveling the entire second route (step S20: YES), the generation unit 200 generates estimated information based on the record of other vehicles traveling the entire second route (step S21).

[0027] If there is no record of other vehicles traveling the entire second route (step S20: NO), the generation unit 200 determines whether there is a record of other vehicles traveling each link of the second route at the time the vehicle traveled (step S30).

[0028] If there is a record of other vehicles traveling on each link of the second route (step S30: YES), the generation unit 200 generates estimated information based on the record of other vehicles traveling on each link of the second route (step S31). If there is no record of other vehicles traveling on each link of the second route (step S30: NO), the generation unit 200 generates estimated information based on the record of other vehicles traveling on the second route at a different date and time than the date and time on which this vehicle traveled (step S40).

[0029] <Second example of a method for generating estimated information> The generation unit 200 may acquire information indicating the driving record of the vehicle when it has actually traveled at least a portion of the second route in the past, and generate estimated information based on the acquired information. For example, the storage unit 400 may store the driving record of the vehicle when it has traveled at least a portion of the second route in the past, and the generation unit 200 may read the driving record of the vehicle when it has traveled at least a portion of the second route in the past from the storage unit 400 to generate estimated information. However, even in this case, as in the first example, it is preferable to use the past driving record of the vehicle when it traveled at least a portion of the second route at a date and time that is as close as possible in terms of conditions to the date and time when the vehicle traveled the first route. The conditions include the time of day, date and time attributes (weekday, public holiday, festival, etc.).

[0030] <Driving Record> Next, we will explain specific examples of driving performance as shown by the aforementioned performance and estimated information.

[0031] Driving records include information on the time taken, distance traveled, energy consumption (such as fuel consumption or electric energy consumption), carbon dioxide emissions, toll road fees, number of intersections, elevation changes, and at least one of the distances traveled at different speed limits, for the journey from a reference point to a destination. Driving records may also include the following information:

[0032] The driving record may include information indicating areas where on-street parking is permitted along each route. Routes with many areas where on-street parking is permitted indicate that it is easier for users to take breaks, etc. Information indicating areas where on-street parking is permitted can be obtained by processing images acquired from an imaging device attached to the vehicle (e.g., a drive recorder) to identify parked cars and designating roads where parked cars have been identified as roads where on-street parking is permitted. Alternatively, areas where on-street parking is permitted may be stored in the storage unit 400 as part of the map information. In this case, the generation unit 200 may use the information indicating each route and the map information to obtain information indicating areas where on-street parking is permitted.

[0033] Furthermore, the driving record may include the number of right or left turns or lane changes along the route. In particular, for large vehicles such as trailers, it is preferable to have fewer right or left turns and lane changes, so it is preferable to include the number of right or left turns and lane changes in the driving record so that they can be compared for each route.

[0034] Furthermore, driving records may include the frequency of near misses, or incidents where a dangerous situation occurred but did not result in an accident, during route driving. Near misses include, for example, pedestrians suddenly running into the road or vehicles obstructing pedestrians at crosswalks. Routes with a low frequency of near misses indicate a lower likelihood of accidents for the user. Information indicating the frequency of near misses can be obtained, for example, by processing images acquired from an imaging device installed in the vehicle (e.g., a dashcam).

[0035] Furthermore, the driving record may include information regarding vehicle height restrictions during route travel. Specifically, it may include information indicating sections of the route with height restrictions and the height of those restrictions. This information is particularly useful when the vehicle is a large vehicle. The information regarding vehicle height restrictions is stored in the storage unit 400 as part of the map information, for example.

[0036] Furthermore, the driving record may include information regarding the user's or passenger's susceptibility to motion sickness during route driving. For example, sensors installed in the vehicle may be used to determine the magnitude of the G-force acting on the user or passenger during route driving, thereby obtaining information regarding the user's or passenger's susceptibility to motion sickness. In the case of a motorcycle, sensors may be used to determine the degree of tilt of the vehicle, thereby obtaining information regarding the user's or passenger's susceptibility to motion sickness.

[0037] Furthermore, the driving record may include information indicating the average speed of surrounding vehicles during route driving. Information indicating the average speed of surrounding vehicles can be obtained, for example, by processing images acquired from an imaging device attached to the vehicle (e.g., a drive recorder) to calculate the relative speed between this vehicle and surrounding vehicles, and by using the history of that relative speed and the speed of this vehicle.

[0038] Furthermore, the driving record may include information indicating the number of facilities such as convenience stores passed during the route. This information can be obtained, for example, by using information about facilities that has been pre-stored in association with map information, or by processing images acquired from an imaging device installed in the vehicle (e.g., a drive recorder). The information indicating the number of facilities passed may also include information indicating whether the facility was on the right or left side of the road during the route.

[0039] Furthermore, the driving record may include information regarding the number of large vehicles that traveled the route. Information regarding the number of large vehicles can be obtained, for example, by processing images acquired from an imaging device attached to the vehicle (e.g., a drive recorder) or based on the driving record of large vehicles stored in an external server or the like that which constitutes the storage unit 400.

[0040] Furthermore, the driving record may include information regarding at least one of the degree of burden or enjoyment for the user or passengers during route driving. The degree of burden or enjoyment for the user or passengers can be obtained, for example, by acquiring images of the vehicle interior using an imaging device such as a Driver Monitoring System (DMS), and based on changes in the facial expressions of the user or passengers included in these images.

[0041] Furthermore, the driving record may include information regarding rerouting due to route errors during route driving. For example, the driving record may include the number of U-turns during route driving as the number of reroutings.

[0042] Furthermore, the driving record may include information about the types of vehicles surrounding the route during the drive. Vehicle types are classified, for example, into large vehicles, passenger cars, motorcycles, commercial vehicles, etc. Information about the types of vehicles surrounding the route can be obtained, for example, by processing images acquired from an imaging device mounted on the vehicle (for example, a dashcam).

[0043] [Output section 300] The output unit 300 outputs difference information that allows for the identification of the difference between the actual information and the estimated information. By outputting the difference information, the output unit 300 outputs the actual information and the estimated information in a manner that allows for comparison. Here, the difference information may be information for displaying the actual information and the estimated information together, or it may be information indicating the difference between the actual information and the estimated information extracted by the difference information generation unit 500 shown in Figure 1. Outputting the actual information and the estimated information in a manner that allows for comparison means displaying the actual information and the estimated information side by side using the difference information, or displaying the difference between the actual information and the estimated information. The timing of the output unit 300 output may be, for example, when the vehicle arrives at its destination, when the vehicle's operation ends (when the engine is turned off), or when the vehicle returns to a pre-registered location such as home.

[0044] Furthermore, the output unit 300 may display route information including at least a portion of the first route and at least a portion of the second route. For example, at least a portion of the first route and at least a portion of the second route may be displayed on the map screen.

[0045] Figure 3 shows an example of a screen output by the output unit 300. The screen shown in Figure 3 includes map area 1 and driving record area 2. In the example shown in Figure 3, the difference information includes information for displaying both actual information and estimated information on the display simultaneously. More specifically, map area 1 displays map information, and on top of the map information, the first route 1a and the second route 1b are displayed. Driving record area 2 displays driving record 2a as shown by the actual information and driving record 2b as shown by the estimated information. The "Driving distance by speed limit" shown in driving record area 2 in Figure 3 is the ratio (e.g., %) of the distance of roads with a set speed limit to the total distance of all roads included in driving record area 2, shown for each speed limit.

[0046] However, the screen output by the output unit 300 is not limited to the example in Figure 3. For example, instead of displaying the route on the map screen, it may be displayed as text including the names of traffic lights and intersections passed. Also, instead of the actual driving record 2b shown by the estimated information, a numerical value showing the difference between the actual driving record 2a shown by the actual information and the actual driving record 2b shown by the estimated information may be displayed. Furthermore, if there are multiple second routes, the actual driving record 2b shown by the estimated information corresponding to each of the multiple second routes may be displayed.

[0047] Furthermore, the output unit 300 may display the driving results for the first and second routes in a manner that allows the user to recognize which of the two routes was preferable. For example, the output unit 300 may display the value corresponding to the preferred route in a different color from the other values, or it may display the value corresponding to the preferred route with an icon.

[0048] Furthermore, if the driving record includes multiple items, the output unit 300 may display which of the first route and the second route was preferable for each of the items in a manner that makes it recognizable. The recognizable manner is as described above. For example, if the above items include the time taken, the value for the shorter time taken may be displayed in a different color from the other values, or an icon may be added to display it. The same applies if the above items include at least one of the following: distance traveled, toll road fees, number of traffic lights passed, magnitude of elevation changes, and distance traveled at different speed limits. It should also be determined that a shorter distance is better, a smaller toll road fee is better, fewer traffic lights passed and less elevation changes are better, and a larger proportion of roads with higher speed limits is better for distance traveled at different speed limits.

[0049] Furthermore, the output unit 300 may output the screen at timings other than those described above. For example, when a route search device such as a navigation system proposes multiple routes and the user selects a route from these multiple routes, estimated information for these multiple routes may be generated and displayed based on the driving history of this vehicle or other vehicles. In this case, it is preferable to use driving history from a past date and time with conditions as close as possible to the date and time when the route is proposed. The conditions include the time of day and the attributes of the date and time (weekday, public holiday, festival, etc.). Furthermore, it is preferable that the estimated information displayed at this time includes at least one of the differences in the number of traffic lights, the number of intersections, and the difference in driving distance for each speed limit from the driving history described above.

[0050] Furthermore, when a user makes the above route selection, the system may use estimated information generated for multiple routes to identify a recommended route and display information indicating the identified recommended route. Here, the recommended route is, for example, the route with the best value for the item that should be given importance among the items included in the estimated information. Here, the item that should be given importance may be set, for example, by input from the user.

[0051] Furthermore, the output unit 300 may display only the items selected by the user from among several items that may be included in the driving record. For example, if the user selects items to be displayed from among several items, including the driving record example described above, the output unit 300 may display only the selected items from the driving record.

[0052] [Storage section 400] Figure 4 shows an example of the vehicle's driving record stored in the memory unit 400. For example, the memory unit 400 stores the route the vehicle traveled, the date and time of travel, and the aforementioned driving record in association with each other. The information shown in Figure 4 is stored, for example, in the storage provided in the vehicle that constitutes the memory unit 400.

[0053] Figure 5 shows an example of the driving records of other vehicles stored in the memory unit 400. For example, the memory unit 400 stores the vehicle identification information of other vehicles, the route traveled by other vehicles, the date and time of travel, and the aforementioned driving records in association with each other. The vehicle identification information is information used to identify a vehicle, and is, for example, a string containing alphanumeric characters. In addition, information including the vehicle type may also be stored in association with each other. Furthermore, the information shown in Figure 5 is stored, for example, in an external server that constitutes the memory unit 400.

[0054] [Example of hardware configuration of information processing device 10] Figure 6 is a block diagram showing an example of the hardware configuration of the information processing device 10. Each functional component of the information processing device 10 may be implemented by hardware (e.g., hardwired electronic circuits) or by a combination of hardware and software (e.g., a combination of an electronic circuit and a program to control it). The case in which each functional component of the information processing device 10 is implemented by a combination of hardware and software will be explained further below.

[0055] The information processing device 10 includes a bus 1020, a processor 1040, a memory 1060, a storage device 1080, an input / output interface 1100, and a network interface 1120. The bus 1020 is a data transmission path for the processor 1040, memory 1060, storage device 1080, input / output interface 1100, and network interface 1120 to send and receive data to and from each other. However, the method of connecting the processor 1040 and the other components is not limited to bus connection.

[0056] Processor 1040 is a variety of processors such as CPU (Central Processing Unit), GPU (Graphics Processing Unit), and FPGA (Field-Programmable Gate Array). Memory 1060 is main memory implemented using RAM (Random Access Memory), etc. Storage device 1080 is auxiliary storage implemented using hard disk, SSD (Solid State Drive), memory card, or ROM (Read Only Memory), etc.

[0057] The input / output interface 1100 is an interface for connecting the information processing device 10 with input / output devices such as the input device 20 and output device 30 described above.

[0058] The network interface 1120 is an interface for connecting the information processing device 10 to a communication network. This communication network may be, for example, a LAN (Local Area Network) or a WAN (Wide Area Network). The network interface 1120 may connect to the communication network via a wireless connection or a wired connection.

[0059] The storage device 1080 stores program modules that realize each functional component of the information processing device 10. The processor 1040 reads these program modules into the memory 1060 and executes them to realize the functions corresponding to each program module.

[0060] Next, the operation of the information processing device 10 according to this embodiment will be described. Figure 7 is a flowchart showing the flow of operation of the information processing device 10 according to this embodiment.

[0061] First, the acquisition unit 100 acquires first route information indicating a first route and second route information indicating a second route (step S100). For example, when a vehicle is in motion, the acquisition unit 100 acquires information indicating each route when multiple routes are proposed by a route search device such as a navigation system. Then, the information indicating the selected (actually driven) route becomes the first route information, and the information indicating the routes that were not selected becomes the second route information.

[0062] Next, when the vehicle travels along the first route, the acquisition unit 100 acquires performance information (step S110). The method for acquiring the driving performance indicated by the performance information is as described above.

[0063] Next, the generation unit 200 acquires the estimated information (step S120). The method for generating the estimated information is as described above.

[0064] Subsequently, the output unit 300 outputs difference information that allows for the identification of the difference between the actual information and the estimated information (step S130). For example, the output unit 300 outputs the difference information at any time after the user has finished driving.

[0065] As described above, the information processing device 10 according to this embodiment allows for a comparison between the actual driving record of the route the user drove and the estimated driving record that would have been obtained if the user had driven a route that they did not actually drive. This helps the user in selecting routes for future trips.

[0066] The embodiments of the present invention have been described above with reference to the drawings, but these are merely examples of the present invention, and various other configurations can also be adopted.

[0067] Furthermore, although the flowchart used in the above description shows multiple steps (processes) in order, the execution order of the steps performed in each embodiment is not limited to the order in which they are described. In each embodiment, the order of the illustrated steps can be changed to the extent that it does not impede the content. Also, the above embodiments can be combined to the extent that their contents do not conflict. [Explanation of Symbols]

The system outputs difference information that can identify the difference between the aforementioned actual information and the aforementioned estimated information. Information processing methods that include the following.
