Mode for Carrying Out the Invention
[0012] Hereinafter, the present disclosure will be described through embodiments, but the disclosure according to the claims is not limited to the following embodiments. Also, not all of the configurations described in the embodiments are essential as means for solving the problems. In each drawing, the same elements are denoted by the same reference numerals, and redundant explanations are omitted as necessary.
[0013] <Embodiment 1> <Information Processing Apparatus> Hereinafter, the configuration of the information processing apparatus according to the present disclosure will be described with reference to FIG. 1. FIG. 1 is a block diagram illustrating the information processing apparatus according to the present disclosure. As shown in FIG. 1, the information processing apparatus 10 includes a control unit 11.
[0014] As shown in Figure 1, the information processing device 10 is configured to communicate with the first communication device 12 and the second communication device 13. The information processing device 10 includes a control unit 11. The information processing device 10 is typically installed in a vehicle. The information processing device 10 is, for example, an ECU (Electronic Control Unit).
[0015] <First communication device> The first communication device 12 shown in Figure 1 will now be described. The first communication device 12 is a communication device installed in the median strip. If there are multiple median strips, the first communication device 12 will be installed in each median strip.
[0016] <Second communication device> The second communication device 13 shown in Figure 1 will now be described. The second communication device 13 is a predetermined communication device installed in the vehicle. It is sufficient to have at least one second communication device 13 installed in the vehicle.
[0017] The first communication device 12 and the second communication device 13 are configured to communicate with each other. That is, the first communication device 12 can transmit predetermined information to the second communication device 13, and the second communication device 13 can receive that information from the first communication device 12. Also, the second communication device 13 can transmit predetermined information to the first communication device 12, and the second communication device 13 can receive that information from the first communication device 12.
[0018] The communication range of the first communication device 12 and the second communication device 13 is the range in which the distance between the median strip and the vehicle is less than or equal to a predetermined distance. In other words, when the vehicle is within the communication range of the first communication device 12 and the second communication device 13, the first communication device 12 and the second communication device 13 become able to communicate with each other.
[0019] <Department Head> The control unit 11 shown in Figure 1 will now be described. The control unit 11 controls a notification unit that alerts the vehicle driver that they are driving in the wrong direction. Here, the notification unit is a device installed in the vehicle, such as a navigation system, a drive recorder, or a console screen.
[0020] Furthermore, the notification unit may be a terminal device or wearable device owned by the vehicle driver. Typically, the notification method of the notification unit is voice notification. However, it is not limited to this, and the notification method of the notification unit may also be to display a warning message on the screen.
[0021] The control unit 11 controls the notification unit based on the transmission and reception status between the first communication device 12 and the second communication device 13. For example, if the first communication device 12 transmits predetermined information received from the second communication device 13 back to the second communication device 13, the control unit 11 controls the notification unit to issue a warning.
[0022] On the other hand, if the first communication device 12 does not receive predetermined information from the second communication device 13, the control unit 11 controls the notification unit so that it does not issue a warning. In other words, the control unit 11 controls whether or not the notification unit issues a warning.
[0023] Thus, the information processing device 10 according to this disclosure controls the notification unit based on the transmission and reception status between the first communication device 12 and the second communication device 13. Therefore, the information processing device 10 can notify the driver of the vehicle driving in the wrong direction with a simpler configuration.
[0024] <Information Processing Methods> Next, we will explain the information processing method related to this disclosure. Figure 2 is a flowchart showing the information processing method related to this disclosure.
[0025] As shown in Figure 2, the information processing device 10 (control unit 11) controls the notification unit based on the transmission and reception status of the first communication device 12 and the second communication device 13 (step ST1). In this way, the information processing device 10 can notify the driver of the vehicle driving in the wrong direction with a simpler configuration.
[0026] <Embodiment 2> <Information Processing System> The configuration of the information processing system relating to this disclosure will be described below with reference to Figure 3. Figure 3 is a block diagram illustrating the information processing system relating to this disclosure. As shown in Figure 3, the information processing system 30 consists of a vehicle 100 and a median strip 200.
[0027] Vehicle 100 includes an information processing device 20, a notification unit 24, and second communication devices 23L and 23R. The information processing device 20 includes a control unit 21. The median strip 200 includes a first communication device 22. That is, the information processing system 30 includes a first communication device 22, second communication devices 23L and 23R, a notification unit 24, and an information processing device 20.
[0028] The second communication device 23L is a communication device located on the left side of the vehicle 100. In Figure 3, the communication device located on the left side of the vehicle 100 is labeled as the second communication device (left). At least one second communication device 23L is required to be located on the left side of the vehicle 100.
[0029] The second communication device 23R is a communication device located on the right side of the vehicle 100. In Figure 3, the communication device located on the right side of the vehicle 100 is labeled as the second communication device (right). At least one second communication device 23R is required to be located on the right side of the vehicle 100.
[0030] The first communication device 22 on the median strip 200 and the second communication devices 23L and 23R on the vehicle 100 are configured to communicate with each other. More specifically, the second communication devices 23L and 23R transmit vehicle identification information to the first communication device 22.
[0031] Here, the second communication devices 23L and 23R are directional communication devices. The second communication device 23L is installed on the left side of the vehicle 100 and transmits the identification information of the vehicle 100 from the vehicle 100 toward the left. The second communication device 23R transmits the identification information of the vehicle 100 toward the right side of the vehicle 100.
[0032] In other words, when the first communication device 22 is located on the left side as viewed from the driver of the vehicle 100, the first communication device 22 receives information from the second communication device 23L. When the first communication device 22 is located on the right side as viewed from the driver of the vehicle 100, the first communication device 22 receives information from the second communication device 23L.
[0033] When the first communication device 22 receives identification information of vehicle 100 from the second communication device 23L, it transmits return information to the second communication device 23L. Also, when the first communication device 22 receives information from the second communication device 23R, it transmits return information to the second communication device 23R.
[0034] Return information is information in which the identification information of the median strip 200 is attached to the identification information of the vehicle 100. Generally, since multiple median strips are arranged on a roadway, it is necessary to clarify which vehicle's second communication device and which median strip's communication device are forming a communication network. By having the second communication device transmit the vehicle's identification information to the first communication device, and the first communication device transmit return information to the second communication device, it is possible to clarify that the communication is between the second communication device of a specific vehicle and the first communication device of a specific median strip.
[0035] Thus, the first communication device 22 and the second communication devices 23L and 23R use vehicle identification information and return information for communication. Since the amount of data for vehicle identification information and return information is small, the information processing system 30 can shorten the communication time between the first communication device 22 and the second communication devices 23L and 23R. Furthermore, by shortening the communication time between the first communication device 22 and the second communication devices 23L and 23R, the information processing system 30 can communicate with multiple vehicles.
[0036] The notification unit 24 is a device installed in the vehicle, such as a navigation system or a drive recorder. The notification unit 24, for example, alerts the driver of the vehicle that it is driving in the wrong direction, for example, by voice.
[0037] <Department Head> The control unit 21 controls the notification unit 24 when the second communication device 23L or the second communication device 23R receives loopback information from the first communication device 22. This will be explained in more detail with reference to Figures 4 to 7. Figures 4 and 5 are explanatory diagrams of when the control unit controls the notification unit. Figures 6 and 7 are data flow diagrams between the first communication device and the second communication device. In Figures 4 and 5, the direction of travel on the roadway is indicated by arrows. In Figures 4 and 5, the vehicle 101 is equipped with the notification unit 24. Note that the control unit 21 is not shown in Figures 4 to 7.
[0038] <Control when not driving in reverse> First, referring to Figures 4 and 6, we will explain an example in which the control unit 21 controls the notification unit 24 so that it does not issue a warning when the second communication device 23R receives loopback information from the first communication devices 22a and 22b.
[0039] As shown in Figure 4, vehicle 101 is equipped with a second communication device 23R on the right side and a second communication device 23L on the left side. Vehicle 101 turns left along trajectory C1, passing through such a position that the median strip 201 is on the right side from the perspective of the driver of vehicle 101. As shown in Figure 4, when vehicle 101 turns left along trajectory C1, it is in the same direction as the roadway, and therefore is not traveling against traffic.
[0040] As shown in Figure 4, when vehicle 101 begins to turn left along trajectory C1, as shown in Figure 6, the second communication devices 23R and 23L transmit the identification information S1 and S2 of vehicle 101 to the first communication device 22a on the median strip 201.
[0041] Since the first communication device 22a is located on the right side as viewed from the driver of vehicle 100, it receives the identification information S1 of vehicle 101 from the second communication device 23R. Also, since the first communication device 22a is located on the right side as viewed from the driver of vehicle 100, it does not receive the identification information S2 of vehicle 101 from the second communication device 23L.
[0042] The first communication device 22a transmits information, which is the identification information of the median strip 201 added to the identification information of the vehicle 101, to the second communication device 23R as return information S3. The second communication device 23R then receives the return information S3 from the first communication device 22a. The control unit 21 determines that the vehicle 101 is not driving in the wrong direction because the second communication device 23R has received the return information from the first communication device 22a. The control unit 21 then controls the notification unit 24 so that it does not issue a warning.
[0043] On the other hand, since the first communication device 22a does not receive the vehicle identification information S2 from the second communication device 23L, it does not transmit the return information S3 to the second communication device 23L.
[0044] Furthermore, as shown in Figure 4, vehicle 101 turns right along trajectory C2, passing through such a position that the median strip 202 is on the right side from the driver's perspective. As shown in Figure 4, when vehicle 101 turns right along trajectory C2, it is in the same direction as the roadway, and therefore is not traveling against traffic.
[0045] In this case as well, similar to the left turn described above, the first communication device 22b on the median strip 202 is located on the right side from the perspective of the driver of vehicle 101, and therefore receives the identification information S1 of vehicle 101 from the second communication device 23R. The second communication device 23R receives the return information S3 from the first communication device 22b. The control unit 21 then determines that vehicle 101 is not going in the wrong direction because the second communication device 23R has received the return information from the first communication device 22b. The control unit 21 then controls the notification unit 24 so that it does not issue a warning.
[0046] <Control when driving in the wrong direction> Next, with reference to Figures 5 and 7, we will explain an example in which the control unit 21 controls the notification unit 24 to issue a warning when the second communication device 23L receives loopback information from the first communication devices 22a and 22b.
[0047] As shown in Figure 5, vehicle 101 is equipped with a second communication device 23R on the right side and a second communication device 23L on the left side. Vehicle 101 turns left along trajectory C3, passing through such a position that the median strip 201 is on the left side from the perspective of the driver of vehicle 101. As shown in Figure 4, when vehicle 101 turns left along trajectory C3, it is moving in the opposite direction to the direction of travel on the roadway, and is therefore traveling against the flow of traffic.
[0048] As shown in Figure 5, when vehicle 101 begins to turn left along trajectory C3, as shown in Figure 6, the second communication devices 23R and 23L transmit the identification information S1 and S2 of vehicle 101 to the first communication device 22a on the median strip 201.
[0049] Since the first communication device 22a is located on the left side as viewed from the driver of vehicle 100, it receives the identification information S2 of vehicle 101 from the second communication device 23L. Also, since the first communication device 22a is located on the left side as viewed from the driver of vehicle 100, it does not receive the identification information S1 of vehicle 101 from the second communication device 23R.
[0050] The first communication device 22a transmits information, which is the identification information of the median strip 201 added to the identification information of the vehicle 101, to the second communication device 23L as return information S3. The second communication device 23L then receives the return information S3 from the first communication device 22a. The control unit 21 determines that the vehicle 101 is driving in the wrong direction because the second communication device 23L has received the return information from the first communication device 22a. The control unit 21 then controls the notification unit 24 to issue a warning.
[0051] On the other hand, the first communication device 22a does not receive the vehicle identification information S1 from the second communication device 23R, and therefore does not transmit the return information S3 to the second communication device 23R.
[0052] Furthermore, as shown in Figure 5, vehicle 101 turns right along trajectory C4, passing through such a position that the median strip 202 is on the right side from the driver's perspective. As shown in Figure 4, when vehicle 101 turns right along trajectory C4, it is going in the opposite direction to the direction of travel on the roadway, and therefore is traveling against the flow of traffic.
[0053] In this case as well, similar to the left turn described above, the first communication device 22b on the median strip 202 is located on the left side from the perspective of the driver of vehicle 101, and therefore receives the identification information S1 of vehicle 101 from the second communication device 23L. The second communication device 23L receives the return information S3 from the first communication device 22b. The control unit 21 determines that vehicle 101 is going in the wrong direction because the second communication device 23L has received the return information from the first communication device 22a. The control unit 21 then controls the notification unit 24 to issue a warning.
[0054] Thus, when the second communication device 23L receives return information from the first communication devices 22a and 22b, the control unit 21 determines that the vehicle 101 is driving in the wrong direction and controls the notification unit 24 to issue a warning. When the second communication device 23R receives return information from the first communication devices 22a and 22b, the control unit 21 determines that the vehicle 101 is not driving in the wrong direction and controls the notification unit 24 not to issue a warning.
[0055] Generally, driving the wrong way at an intersection with a median strip occurs due to a human error in perceiving the direction of travel on the roadway. If the driver continues driving without realizing they are driving the wrong way, it can lead to a serious accident. However, as described above, the information processing system 30 has a control unit 21 that determines whether or not a vehicle is driving the wrong way based on the transmission and reception status between the first and second communication devices, and controls the notification unit 24. With this configuration, the information processing system 30 can notify the driver of driving the wrong way at an intersection with a median strip, allowing the driver to take evasive action to avoid an accident quickly.
[0056] Furthermore, the information processing system 30 has a simple configuration, as it is equipped with a first communication device in the vehicle and a second communication device in the median strip. In other words, the information processing system 30 establishes a simple communication network between the vehicle and the median strip. Moreover, since it only requires the installation of a second communication device in the median strip, the intersection structure becomes simple without requiring extensive construction work. Therefore, the information processing system 30 can notify drivers of vehicles driving in the wrong direction with its simple configuration.
[0057] In Figures 6 and 7, the second communication device 23R transmits the vehicle identification information S1, and then the second communication device 23L transmits the vehicle identification information S2. The timing of the second communication device 23R transmitting the vehicle identification information S1 and the timing of the second communication device 23L transmitting the vehicle identification information S2 may be simultaneous or may be in any order.
[0058] <Control Timing> Next, the timing at which the control unit 21 controls the notification unit 24 will be explained. The control unit 21 controls the notification unit based on the transmission and reception status between the first communication device 22 and the second communication devices 23L and 23R until the vehicle has completed a right or left turn at an intersection with a median strip.
[0059] Furthermore, the control unit 21 may control the notification unit based on the transmission and reception status between the first communication unit 22 and the second communication units 23L and 23R when a vehicle begins to turn right or left at an intersection with a median strip. In other words, the control unit 21 controls the notification unit 24 based on the transmission and reception status between the first communication unit 22 and the second communication units 23L and 23R from the time the vehicle begins to turn right or left at an intersection with a median strip until the turn is completed.
[0060] Let's explain this in more detail with reference to Figure 8. Figure 8 is an explanatory diagram of the timing at which the control unit controls the notification unit. The configuration of the vehicle 101 and the median strip 201 shown in Figure 8 is the same as that shown in Figure 5. In Figure 8, the vehicle 101 is equipped with a notification unit 24. Note that the control unit 21 is not shown in Figure 8. Figure 8 corresponds to the left turn operation of the vehicle 101 along the trajectory C3 in Figure 5.
[0061] As shown in Figure 8, an example will be described in which the control unit 21 controls the notification unit 24 based on the transmission and reception status between the first and second communication devices at point A1 or point A2, when the vehicle 101 is making a left turn along trajectory C3 and traveling against the flow of traffic on the roadway. Point A1 is the point where the vehicle begins its left turn. Point A2 is the point where the vehicle completes its left turn. The explanation will be given with reference to the data flow diagram shown in Figure 7 as appropriate.
[0062] <Point A2> At point A2 shown in Figure 8, when the vehicle has completed a left turn, the second communication devices 23R and 23L transmit the identification information S1 and S2 (see Figure 7) of the vehicle 101 to the first communication device 22a on the median strip 201.
[0063] The first communication device 22a receives identification information S2 (see Figure 7) for vehicle 101 from the second communication device 23L. The first communication device 22a then adds the identification information of the median strip 201 to the identification information of vehicle 101 and transmits this information to the second communication device 23L as return information S3 (see Figure 7) (see Figure 7). As a result, the control unit 21 determines that vehicle 101 is driving in the wrong direction because the second communication device 23L has received the return information from the first communication device 22a. The control unit 21 then controls the notification unit 24 to issue a warning.
[0064] Although not shown in Figure 8, even if vehicle 101 is not driving against traffic on the roadway, the control unit 21 controls the notification unit 24 not to issue a warning based on the transmission and reception status between the first and second communication devices at the point where the left turn is completed.
[0065] In other words, the control unit 21 controls the notification unit 24 based on the transmission and reception status between the first and second communication devices at point A2 where the vehicle has completed its left turn. As a result, the information processing system 30 notifies the driver of the vehicle 101 that it is driving in the wrong direction after it has entered a roadway with a direction of travel opposite to the direction of travel, so that the driver can take accident avoidance actions such as stopping the vehicle 101.
[0066] Naturally, when a vehicle begins to turn right, the control unit 21 controls the notification unit 24 based on the transmission and reception status between the first and second communication devices at the point where the vehicle has completed its right turn.
[0067] <Location A1> When vehicle 101 begins to turn left at point A1 shown in Figure 8, the second communication devices 23R and 23L transmit the identification information S1 and S2 (see Figure 7) of vehicle 101 to the first communication device 22a on the median strip 201.
[0068] The first communication device 22a receives identification information S2 (see Figure 7) for vehicle 101 from the second communication device 23L. The first communication device 22a then adds the identification information of the median strip 201 to the identification information of vehicle 101 and transmits this information to the second communication device 23L as return information S3 (see Figure 7) (see Figure 7). As a result, the control unit 21 determines that vehicle 101 is driving in the wrong direction because the second communication device 23L has received the return information from the first communication device 22a. The control unit 21 then controls the notification unit 24 to issue a warning.
[0069] Although not shown in Figure 8, even if vehicle 101 is not driving against traffic on the roadway, the control unit 21 controls the notification unit 24 not to issue a warning based on the transmission and reception status between the first and second communication devices at the left turn initiation point.
[0070] In other words, the control unit 21 controls the notification unit 24 based on the transmission and reception status between the first and second communication devices at point A1 where the vehicle began to turn left. As a result, the information processing system 30 can notify the driver of wrong-way driving at an intersection with a median strip at an earlier time, allowing the driver to take evasive action to avoid an accident promptly.
[0071] Naturally, if the vehicle begins to turn right, the control unit 21 controls the notification unit 24 based on the transmission and reception status between the first and second communication devices at the point where the vehicle began to turn right.
[0072] Here, an example has been described in which the control unit 21 controls the notification unit 24 based on the transmission and reception status of the first and second communication devices at point A1 or point A2. However, the control unit 21 is not limited to this, and it is sufficient for the control unit 21 to control the notification unit 24 based on the transmission and reception status of the first and second communication devices at any point between point A1 and point A2 along the trajectory C3.
[0073] Vehicle 101 acquires information regarding steering operations, such as when it starts or completes a right or left turn. Based on the steering operation information, the second communication device 23L or 23R of vehicle 101 transmits vehicle identification information to the first communication device 22.
[0074] For example, the second communication unit 23L or 23R recognizes the moment the driver turns the steering wheel to the left as the moment the left turn begins, and transmits vehicle identification information to the first communication unit 22. In response, the control unit 21 controls the notification unit 24 as described above.
[0075] As another example, the second communication unit 23L or 23R recognizes the timing when the driver returns the steering wheel to its original position from the left side as the timing when the left turn is completed, and transmits vehicle identification information to the first communication unit 22. In response, the control unit 21 controls the notification unit 24 as described above.
[0076] <Installation of the second communication device> In the aforementioned information processing system 30, an example was described in which the second communication device 23L is located on the left side of the vehicle and the second communication device 23R is located on the right side of the vehicle. However, the system is not limited to this example, and in the information processing system 30, the second communication device 23L may be located on the left side of the vehicle, and the second communication device 23R may not be located on the vehicle at all.
[0077] Even with this configuration, the information processing system 30 determines that the vehicle is driving in the wrong direction when the second communication device receives return information from the first communication device, and controls the notification unit to issue a warning. Furthermore, since the vehicle's second communication device 23R is not required, costs can be reduced. Thus, the information processing system 30 can notify the driver of the vehicle driving in the wrong direction with a simple and low-cost configuration.
[0078] In Japan, since traffic drives on the left, if a vehicle is driving against traffic, the median strip will be on the left side from the driver's perspective. Therefore, it is preferable that the second communication device 13 be installed on the left side of the vehicle. On the other hand, in other countries where traffic drives on the right, such as the United States, if a vehicle is driving against traffic, the median strip will be on the right side from the driver's perspective. Therefore, it is preferable that the second communication device 13 be installed on the right side of the vehicle.
[0079] Furthermore, the information processing device is not limited to being an ECU, and may be provided in a drive recorder. Also, as shown in Figure 3, the vehicle 100 typically includes an information processing device 20. However, it is not limited to this, and the vehicle 100 may not include an information processing device 20, but instead have a server that can communicate with the vehicle 100 and the median strip 200. In this case, the server includes a control unit 21. That is, the processing of the control unit 21 may be executed in the server.
[0080] <Information Processing Methods> Next, we will explain the information processing method related to this disclosure. Figure 9 is a flowchart showing the information processing method related to this disclosure.
[0081] As shown in Figure 9, when the vehicle begins to turn right or left (step ST01), the second communication devices located on the left and right sides of the vehicle transmit vehicle identification information to the first communication device (step ST02).
[0082] Next, the first communication device transmits to the first communication device, as return information, information that includes the identification information of the median strip added to the vehicle identification information received from the second communication device (step ST03).
[0083] Next, the control unit determines whether the number of communications between the first and second communicators is less than or equal to a predetermined number (step ST04). If the number of communications between the first and second communicators is less than or equal to the predetermined number (step ST04YES), the control unit determines whether the second communicator on the left has received the return information (step ST05).
[0084] On the other hand, if the number of communications between the first and second communication devices is not less than a predetermined number (step ST04NO), the control unit determines that the communication between the first and second communication devices is abnormal and terminates. In this way, the control unit has a timeout function based on the number of communications between the first and second communication devices.
[0085] If the control unit determines that the second communication device on the left has received return information (step ST05YES), it determines that the vehicle is driving in the wrong direction and controls the notification unit 24 to issue a warning (step ST07).
[0086] On the other hand, if the control unit does not determine that the second communication device on the left has received the loopback information (step ST05NO), it determines whether or not the second communication device on the right has received the loopback information (step ST06).
[0087] If the control unit determines that the second communication device on the right has received return information (step ST06YES), it determines that the vehicle is not going in the wrong direction and controls the notification unit 24 so as not to issue a warning (step ST08).
[0088] If the control unit does not determine that the second communication device on the right has received the return information (step ST06NO), it repeats the process from step ST2.
