Abstract
Description
Technical Field
[0001] This invention relates to an information processing device for vehicles. Background Technology
[0002] Japanese Patent Application Publication No. 2022-143024 discloses a system comprising a server and an in-vehicle information communication device. The in-vehicle information communication device sends information related to the vehicle's current location to the server. The in-vehicle information communication device sends location information to the server during traffic jams or other congestion, and suppresses the transmission of location information when there is no congestion. With this structure, the in-vehicle communication device can efficiently notify the vehicle's location during congestion while minimizing the number of communications during non-congestion periods, thereby enabling notification of road congestion conditions. Summary of the Invention
[0003] Vehicle location information can be used not only to monitor traffic congestion but also to record vehicle driving history and conduct traffic flow surveys. If the communication frequency between the information processing device on the vehicle and the server is too low, the vehicle's location cannot be accurately determined. On the other hand, if the communication frequency between the information processing device and the server is too high, it will increase the load on the information processing device.
[0004] The following describes the methods used to solve the above problems and their effects.
[0005] The information processing device for a vehicle used to solve the above-mentioned problems includes:
[0006] A location information acquisition device that acquires information indicating the location of a vehicle;
[0007] An information transmitting device periodically transmits information representing the vehicle's location, acquired by the location information acquiring device, to a server; and
[0008] Storage device.
[0009] In the vehicle information processing device, the lower the vehicle's speed, the shorter the interval at which information indicating the vehicle's position is sent to the server. The vehicle information processing device determines whether a recording trigger condition is met based on changes in the vehicle's direction of travel. If the recording trigger condition is met, the device stores information indicating the vehicle's position at the time the recording trigger condition is met in the storage device.
[0010] Based on the information processing device of the aforementioned vehicle, it is able to determine the accurate change of travel route without relying on roads or terrain, and therefore can accurately record left turns / right turns or U-turns at intersections or forks in the road.

[0019] Figure 6 This is a diagram illustrating an example of determining the path of a vehicle using the vehicle information processing device according to the embodiment. Detailed Implementation
[0020] The following is for reference. Figures 1 to 6 The implementation of the vehicle information processing device 10 will be described.
[0021] Structure of Information Processing Device 10
[0022] like Figure 1As shown, the information processing device 10 is mounted on the vehicle 100. The information processing device 10 is connected to a server 200 to communicate. Furthermore, the information processing device 10 sends information indicating the current location of the vehicle 100 to the server 200. The information processing device 10 and the server 200 together constitute the vehicle's information processing system. Based on the information indicating the vehicle 100's location, the server 200 manages information such as road congestion conditions or the vehicle 100's driving history. This information can be used for traffic flow surveys, etc. The server 200 collects and analyzes a large amount of vehicle location information data. Furthermore, the server 200 organizes the collected data and provides it.
[0023] like Figure 1 As shown, the information processing device 10 is configured with a location information acquisition device 20, an information transmission device 30, and a storage device 40. The location information acquisition device 20 acquires information indicating the current location of the vehicle 100. In this embodiment, the location information acquisition device 20 uses radio waves received from a satellite by a receiver of a satellite positioning system to acquire information indicating the current location of the vehicle 100. Hereinafter, the information indicating the current location of the vehicle 100 is also referred to as location information.
[0024] The information transmitting device 30 periodically transmits the location information of the vehicle 100, acquired by the location information acquisition device 20, to the server 200. The transmission interval is set according to the speed of the vehicle 100. The transmission interval is the interval at which the information transmitting device 30 transmits the location information of the vehicle 100 to the server 200. The lower the speed of the vehicle 100, the shorter the transmission interval is set. That is, with a short transmission interval, the frequency of sending location information to the server 200 increases compared to a large transmission interval, resulting in a denser transmission of location information to the server 200.
[0025] The storage device 40 is implemented, for example, by random access memory (RAM), read-only memory (ROM), hard disk drive (HDD), etc. The storage device 40 stores information indicating the location of the vehicle 100, etc.
[0026] Processing flow of information processing device 10 sending location information of vehicle 100
[0027] The following is for reference. Figure 2 The processing flow of the location information of vehicle 100 sent by information processing device 10 is explained in detail. Figure 2 The series of processes shown are repeatedly executed by the information processing device 10 during the operation of vehicle 100. For example... Figure 2As shown, if this series of processes begins, the information processing device 10 first obtains the location information of the vehicle 100 by the location information acquisition device 20 in the processing of S100. Then, the information processing device 10 proceeds to the processing in S110.
[0028] In the processing of S110, the information processing device 10 confirms the speed of the vehicle 100. The speed of the vehicle 100 can be obtained using known methods such as speed detected by a vehicle speed sensor mounted on the vehicle 100 or speed displayed on the vehicle 100's dashboard. Then, the information processing device 10 proceeds to S120, where, based on the speed of the vehicle 100 obtained in S110, a transmission interval for sending the vehicle 100's location information to the server 200 is determined. Next, the information processing device 10 proceeds to S130, where it is determined whether the transmission opportunity corresponding to the transmission interval determined in S120 has arrived. If the transmission opportunity corresponding to the transmission interval has arrived (S130: Yes), the information processing device 10 proceeds to S140. In the processing of S140, the information processing device 10 sends the vehicle 100's location information obtained through the processing of S100 to the server 200. On the other hand, if the transmission opportunity corresponding to the transmission interval has not arrived (S130: No), the information processing device 10 repeatedly executes the processing of S130.
[0029] Then, the information processing device 10 returns to the series of processes.
[0030] Processing flow using recorded trigger conditions
[0031] The following is for reference. Figure 3 The process of recording the position of vehicle 100 using recording trigger conditions is described in detail below. This series of processes is repeatedly executed by information processing device 10 during the operation of vehicle 100. Figure 3 As shown, if this series of processes begins, the information processing device 10 first determines, in process S200, whether the speed of the vehicle 100 is less than a predetermined value. In process S200, if the information processing device 10 determines that the speed of the vehicle 100 is less than the predetermined value (S200: Yes), the process proceeds to S210. On the other hand, if the information processing device 10 determines that the speed of the vehicle 100 is greater than or equal to the predetermined value (S200: No), the process returns to its previous state.
[0032] When processing proceeds to S210, the information processing device 10 determines whether the recording trigger condition is met during the processing in S210. In this embodiment, the recording trigger condition is a condition for starting automatic recording of information indicating the position of the vehicle 100 when a specific event or situation occurs. The recording trigger condition is, for example, a logical AND condition of the following two conditions. That is, the information processing device 10 determines that the recording trigger condition is met by the state where both of the following conditions are met.
[0033] The true orientation of vehicle 100 before its direction of travel begins to change changes with the true orientation at the moment when its direction of travel stops changing.
[0034] • The direction of travel of vehicle 100 changed by more than 45 degrees from the time it began to change until it stopped changing.
[0035] True bearing is the azimuth angle measured with true north as the reference, and clockwise direction is set as the positive angle. If true bearing is used to represent the direction of travel, then north is 0 degrees, east is 90 degrees, south is 180 degrees, and west is 270 degrees.
[0036] In the process of S210, if the information processing device 10 determines that the recording trigger condition is met (S210: Yes), it proceeds to S220, where it records the location information of the vehicle 100. Then, the information processing device 10 proceeds to S230, where it sends the location information of the vehicle 100 to the server 200. Finally, the information processing device 10 returns to the previous processing sequence.
[0037] On the other hand, in the processing of S210, if the information processing device 10 determines that the recording trigger condition is not met (S210: No), it returns to processing.
[0038] When vehicle 100 turns right at the intersection
[0039] The following is for reference. Figure 4A , Figure 4B This section provides a specific example of vehicle 100 turning right at an intersection.
[0040] In this embodiment, the change in the true orientation of the vehicle 100 is detected by detecting the steering of the vehicle 100. As the mechanism for detecting the steering motion of the vehicle 100, various sensors mounted on the vehicle 100 can be used, employing known techniques. For example, an angular velocity sensor can be used to measure the angular velocity of the vehicle during turning in real time, and the steering motion of the vehicle can be detected based on this measurement. Furthermore, an acceleration sensor can be used to measure the lateral acceleration (lateral G) generated when the vehicle turns in real time, thereby detecting the vehicle's movement on curves such as left / right turns. Moreover, there are methods that use a steering angle sensor to measure the angle at which the driver turns the steering wheel and predict the vehicle's turning action based on the result, thereby detecting entry into a curve. Additionally, wheel speed sensors can be used to measure the speed difference between the inner and outer wheels of the vehicle in real time, thereby detecting the vehicle's turning action. As long as the vehicle's steering can be detected, the specific method is not limited, and the above-described techniques or other techniques known as existing technology can be combined arbitrarily.
[0041] Figure 4A This is a diagram illustrating the behavior of vehicle 100 when making a right turn. For example... Figure 4A As shown, in this example, vehicle 100 turns right along the hollow arrow while passing through the intersection. Figure 4A In the diagram, a graphic consisting of solid circles and dashed crosses represents the true bearing. The circle represents the bearing reference, and the crosses represent the cardinal directions (north, south, east, west). Before vehicle 100 enters the intersection, its direction of travel is north, and its true bearing is 0 degrees. If vehicle 100 enters the intersection at time t1, it begins to turn right. Various sensors mounted on vehicle 100 begin detecting changes in its direction of travel from time t1. As vehicle 100 enters the intersection as indicated by the arrow, its direction of travel gradually changes from north to east, clockwise. The true bearing of vehicle 100 gradually increases clockwise from 0 degrees, reaching 30 degrees, and then approaches 90 degrees. At time t2, just after vehicle 100 has exited the intersection, its direction of travel becomes east, and its true bearing becomes 90 degrees. From time t2 onwards, the direction of travel of vehicle 100 stops changing. The various sensors mounted on the vehicle 100 start detecting the vehicle 100's direction of travel from time t2, and continue this state of no change of direction of travel for a predetermined period of time, until time t3, when the direction of travel stops changing.
[0042] Figure 4B The diagram shows a timeline illustrating the change in the true orientation of vehicle 100 over time. (Example) Figure 4BAs shown, the true bearing begins to change from time t1. At time t2, the true bearing of vehicle 100 becomes 90 degrees. From time t2, when the true bearing stops changing, the true bearing remains unchanged. At time t1, when the direction of travel of vehicle 100 begins to change, the true bearing is 0 degrees; at time t2, when the direction of travel of vehicle 100 stops changing, the true bearing is 90 degrees. The true bearing remains unchanged at 90 degrees until time t3, which is the duration of the predetermined period.
[0043] In this situation, the true bearing at time t1 before the vehicle 100's direction of travel begins to change is 0 degrees, while at time t2 when the vehicle 100's direction of travel stops changing, the true bearing is 90 degrees, thus the true bearing has changed. Furthermore, during the period from when the vehicle 100's direction of travel begins to change until it stops changing, the direction of travel changes from north to east, thus changing by 90 degrees. Therefore, when the vehicle 100 turns right at the intersection, the information processing device 10 determines that the recording trigger condition is met at time t3 when the true bearing remains unchanged for a predetermined period (S210: Yes). The time when the recording trigger condition is met is the time t2 when the vehicle 100's direction of travel stops changing. As a result, the information processing device 10 records the intersection as the position of the vehicle 100 (processing in S220).
[0044] Vehicle 100 changing lanes
[0045] The following is for reference. Figure 5A , Figure 5B This section provides a specific example of a vehicle changing lanes.
[0046] Figure 5A This is a diagram illustrating the behavior of vehicle 100 when changing lanes. For example... Figure 5A As shown, in this example, vehicle 100 changes lanes along the hollow arrow. Up to time t1, vehicle 100 is traveling straight in its current lane, heading east, with a true bearing of 90 degrees. This state indicates that vehicle 100 is steadily traveling in its current lane. At time t2, vehicle 100 begins to change lanes, changing its direction of travel from east to north, and its true bearing from 90 degrees to 60 degrees. At time t2, vehicle 100 leaves its current lane and begins to move into an adjacent lane. From time t2 onwards, the true bearing becomes 60 degrees, and remains at 60 degrees until time t3. At time t4, vehicle 100 returns to its straight-ahead direction, this time east. At time t4, the true bearing returns to 90 degrees. From time t4 onwards, vehicle 100 transitions to a straight-ahead state in its new lane.
[0047] Figure 5B It is a time sequence diagram showing how the behavior of vehicle 100 changes over time. Figure 5B This represents the change in the true orientation of vehicle 100 during a lane change and the duration during which its true orientation remains unchanged. Up to time t1, vehicle 100 maintains a true orientation of 90 degrees. This state indicates that vehicle 100 is traveling straight in its current lane. Then, from time t1 to time t2, the true orientation of vehicle 100 gradually changes from 90 degrees to 60 degrees. This change in true orientation indicates that vehicle 100 begins to change lanes. At time t2, the true orientation of vehicle 100 becomes 60 degrees, and this state continues until time t3. The period from time t2 to time t3 indicates that vehicle 100 enters an adjacent lane from its current lane. At time t3, the true orientation of vehicle 100 changes again, returning to 90 degrees at time t4. This behavior indicates that vehicle 100 has entered an adjacent lane and its direction of travel has turned east. From time t3 to time t4, the state of no change in direction of travel continues, but the duration from time t3 to time t4 is shorter than the predetermined period. Therefore, the information processing device 10 does not end the detection of the direction of travel. From time t4, the direction of travel of the vehicle 100 stops changing. The detection of the direction of travel ends at time t5, when the various sensors mounted on the vehicle 100 continue in the state of no change of direction of travel for a predetermined period.
[0048] In this situation, the true bearing of vehicle 100 before its direction of travel begins to change is 90 degrees, and the true bearing at the moment when its direction of travel stops changing is also 90 degrees; therefore, the true bearing has not changed. Furthermore, the direction of travel of vehicle 100 at the moment t1 when its direction of travel begins to change is eastward, and the direction of travel of vehicle 100 at the moment t4 when its direction of travel stops changing is eastward; therefore, the change in direction of travel is 0 degrees. Thus, when vehicle 100 changes lanes, the information processing device 10 determines that the recording trigger condition is not met (S210: No). As a result, the information processing device 10 does not record the position of vehicle 100.
[0049] Example of determining the driving path of vehicle 100 by information processing device 10
[0050] Next, use Figure 6 An example of determining the driving path by the information processing device 10 will be explained. Figure 6 This is a diagram used to illustrate the driving path of vehicle 100. Figure 6 In the diagram, solid lines represent the actual path traveled by vehicle 100, while dashed lines represent other possible paths taken by vehicle 100. Furthermore, Figure 6The arrows shown indicate the vehicle's location, sent from vehicle 100 to server 200 at intervals set according to vehicle 100's speed. Server 200 only collects the locations indicated by these arrows, and thus can obtain the travel path by connecting the locations indicated by these arrows with a double-dotted line. However, it is not possible to determine from the travel path indicated by this double-dotted line whether the actual path traveled by vehicle 100 is a solid line or a dashed line.
[0051] In this embodiment, the information processing device 10 determines whether a recording trigger condition is met based on changes in the travel direction of the vehicle 100 at positions A, B, and C. At position A, the following two conditions are met: the travel direction of the vehicle 100 changes by more than 45 degrees; and the true orientation of the vehicle 100 before the change in travel direction changes is different from the true orientation at the moment the change in travel direction stops. Therefore, the information processing device 10 can determine that the recording trigger condition is met when the vehicle 100 is traveling at position A. Thus, the information processing device 10 stores the position information of the vehicle 100 at position A in the storage device 40. Furthermore, the information processing device 10 stores the positions B and C in the storage device 40 in the same way as it does position A. In this way, the information processing device 10 can record positions where important route changes have occurred, such as left / right turns, U-turns, and route selection at intersections.
[0052] The function of this implementation method
[0053] The information processing device 10 includes: a location information acquisition device 20 for acquiring information indicating the location of a vehicle 100; an information transmission device 30 for periodically transmitting the location information indicating the location of the vehicle 100 acquired by the location information acquisition device 20 to a server 200; and a storage device 40. The information processing device 10 sets a shorter transmission interval for sending information indicating the location of the vehicle 100 to the server 200 as the vehicle speed decreases. The information processing device 10 determines whether a recording trigger condition is met based on changes in the vehicle 100's direction of travel. If the recording trigger condition is met, the information indicating the location of the vehicle 100 at the time the recording trigger condition is met is stored in the storage device 40.
[0054] The aforementioned information processing device 10 sends information indicating the position of vehicle 100 to server 200 at a higher frequency when moving at low speeds by setting a shorter transmission interval as the vehicle speed decreases. Then, the information processing device 10 records information indicating the position of vehicle 100 when a recording trigger condition based on a change in the direction of travel of vehicle 100 is met.
[0055] Effects of this implementation method
[0056] (1) For example, in busy streets or residential areas, there are many intersections due to the density of facilities or residences, and there are often multiple routes connecting the intersections. When the vehicle 100 is moving at a low speed in such an area, the information processing device 10 can send the location of the vehicle 100 to the server 200 at a high frequency by shortening the transmission interval according to the vehicle speed, thereby providing detailed movement information.
[0057] Furthermore, when the recording trigger condition based on the change in the vehicle 100's direction of travel is met, the information processing device 10 stores information indicating the current position of the vehicle 100 in the storage device 40. In this way, the information processing device 10 can record locations where important route changes have occurred, such as left / right turns, U-turns, and route selections at intersections. Therefore, even when the vehicle 100 is traveling in an area with multiple routes at intersections, the information processing device 10 can provide accurate trajectory information. Thus, the information processing device 10 can determine accurate route changes without relying on roads or terrain, and therefore can accurately record left / right turns or U-turns at intersections or forks in the road.
[0058] (2) The information processing device 10 determines that the recording trigger condition is met when the following two conditions are met: the true orientation of the vehicle 100 before the direction of travel begins to change changes and the true orientation of the vehicle 100 at the moment when the direction of travel stops changing changes; and the direction of travel changes by more than 45 degrees during the period from when the direction of travel of the vehicle 100 begins to change until it stops changing.
[0059] In the aforementioned information processing device 10, temporary changes in the vehicle 100's direction of travel are excluded. Only clear changes in direction, such as left / right turns at intersections, are recorded to trigger the recording condition. Thus, minor changes in direction of travel caused by lane changes or road irregularities are excluded by recording the trigger condition.
[0060] (3) When the direction of travel of the vehicle 100 does not change for a predetermined period of time from the moment when the direction of travel of the vehicle 100 stops changing, the information processing device 10 determines whether the recording trigger condition is met. If the recording trigger condition is met, the moment when the direction of travel stops changing is taken as the moment when the recording trigger condition is met.
[0061] When changing lanes, the direction of travel is changed to the target lane, and although this is for a short period, the direction of travel is sometimes maintained until the target lane is reached. Then, once the movement to the target lane is complete, the direction of travel returns to the original direction of travel. In this structure, the recording trigger condition is determined to be met based on the fact that the state of no change in the direction of travel continues for a predetermined period. Therefore, it is possible to avoid recording two changes of direction of travel within a short period of time during lane changing separately.
[0062] (4) When the information processing device 10 determines that the recording trigger condition is met, it sends information indicating the location of the vehicle 100 when the recording trigger condition is met to the server 200.
[0063] In the aforementioned information processing device 10, information about the location where the travel route has changed is sent to the server 200 in real time. Therefore, the information processing device 10 can build a foundation for generating accurate driving paths in real time based on changes in the travel route of the vehicle 100, thus contributing to the upgrading of traffic condition analysis.
[0064] Change Example
[0065] This embodiment can be modified as follows. This embodiment and the following modifications can be combined with each other within the scope of technical inconsistency.
[0066] In the above embodiment, when the information processing device 10 determines that a recording trigger condition has been met, it sends information indicating the position of the vehicle 100 at the time the recording trigger condition has been met to the server 200. However, the timing of sending this information can be varied. For example, the information processing device 10 may send information indicating the position of the vehicle 100 at a timing corresponding to a transmission interval defined based on the vehicle speed of the vehicle 100, along with information stored in the storage device 40 indicating the position of the vehicle 100 at the time the recording trigger condition has been met, to the server 200.
[0067] In this scenario, the information processing device 10, if the recording trigger condition is met, does not immediately send information indicating the position of the vehicle 100 to the server 200, but rather sends it at intervals based on the transmission interval. In areas where the direction of travel changes frequently, the recording trigger condition is likely to be met repeatedly. By adopting this structure, the information processing device 10 temporarily stores the recorded content in the storage device 40 and sends it at intervals corresponding to the vehicle speed, thereby suppressing the number of transmissions. As a result, the load on the information processing device 10 can be reduced.
[0068] • In this implementation, if it is determined that the speed of vehicle 100 is less than a predetermined value (S200: Yes), it is determined whether the recording trigger condition is met. However, it is also possible to determine whether the recording trigger condition is met throughout the operation of vehicle 100, regardless of the speed of vehicle 100.
[0069] In this embodiment, true bearing is used to determine changes in the direction of travel. However, as long as the change in the direction of travel can be determined, left-handed or right-handed coordinate systems or relative direction data can also be used. For example, changes in the direction of travel can be determined without using true bearing by utilizing relative bearing or direction of travel data obtained from the vehicle's sensors.
