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 necessarily essential as means for solving the problems. In each drawing, the same elements are denoted by the same reference numerals, and duplicate explanations are omitted as necessary.

[0013] <Embodiment 1> <Information Processing Apparatus> Hereinafter, with reference to FIG. 1, the configuration of the information processing apparatus according to the present disclosure will be described. FIG. 1 is a block diagram exemplifying 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 FIG. 1, the information processing apparatus 10 is configured to be able to communicate with the first communication device 12 and the second communication device 13. The information processing apparatus 10 includes a control unit 11. The information processing apparatus 10 is typically provided in a vehicle. The information processing apparatus 10 is, for example, an ECU (Electronic Control Unit).

[0015] <First communication device> The first communication device 12 shown in FIG. 1 will be described. The first communication device 12 is a communication device provided in the median strip. When there are a plurality of median strips, the first communication device 12 is provided in each median strip.

[0016] <Second communication device> The second communication device 13 shown in FIG. 1 will be described. The second communication device 13 is a predetermined communication device provided in the vehicle. At least one second communication device 13 may be provided in the vehicle.

[0017] The first communication device 12 and the second communication device 13 are configured to be able 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 the 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 the information from the first communication device 12.

[0018] The communication ranges of the first communication device 12 and the second communication device 13 are in a range where the distance between the median strip and the vehicle is equal to or less than a predetermined distance. That is, when the vehicle belongs to the communication ranges of the first communication device 12 and the second communication device 13, the first communication device 12 and the second communication device 13 can communicate with each other.

[0019] <Control unit> The control unit 11 shown in FIG. 1 will be described. The control unit 11 controls a notification unit that alerts the driver of the vehicle that it is driving in reverse. Here, the notification unit is a device provided in the vehicle, for example, a navigation device, a drive recorder, or a console screen.

[0020] Further, the notification unit may be a terminal device or a wearable device held by the driver of the vehicle. The notification method of the notification unit is typically a notification method by voice. However, it is not limited to this, and the notification method of the notification unit may be a method of displaying a message for alerting on the screen.

[0021] The control unit 11 controls the notification unit based on the transmission and reception states of the first communication unit 12 and the second communication unit 13. For example, when the first communication unit 12 re-transmits the predetermined information received from the second communication unit 13 to the second communication unit 13, the control unit 11 controls the notification unit to issue an alert.

[0022] On the other hand, when the first communication unit 12 does not receive the predetermined information from the second communication unit 13, the control unit 11 controls the notification unit not to issue an alert. In other words, the control unit 11 controls whether the notification unit issues an alert.

[0023] As described above, the information processing apparatus 10 according to the present disclosure controls the notification unit based on the transmission and reception states of the first communication unit 12 and the second communication unit 13. Therefore, the information processing apparatus 10 can notify the driver of the reverse running of the vehicle with a simpler configuration.

[0024] <Information Processing Method> Subsequently, the information processing method according to the present disclosure will be described. FIG. 2 is a flowchart showing the information processing method according to the present disclosure.

[0025] As shown in FIG. 2, the information processing apparatus 10 (control unit 11) controls the notification unit based on the transmission and reception states of the first communication unit 12 and the second communication unit 13 (step ST1). In this way, the information processing apparatus 10 can notify the driver of the reverse running of the vehicle with a simpler configuration.

[0026] <Embodiment 2> <Information Processing System> Hereinafter, the configuration of the information processing system according to the present disclosure will be described with reference to FIG. 3. FIG. 3 is a block diagram illustrating the information processing system according to the present disclosure. As shown in FIG. 3, the information processing system 30 is composed of a vehicle 100 and a median strip 200.

[0027] The 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 the first communication device 22, the second communication devices 23L and 23R, the notification unit 24, and the information processing device 20.

[0028] The second communication device 23L is a communication device provided on the left side of the vehicle 100. In FIG. 3, the communication device provided on the left side of the vehicle 100 is denoted as the second communication device (left). At least one second communication device 23L may be provided on the left side of the vehicle 100.

[0029] The second communication device 23R is a communication device provided on the right side of the vehicle 100. In FIG. 3, the communication device provided on the right side of the vehicle 100 is denoted as the second communication device (right). At least one second communication device 23R may be provided on the right side of the vehicle 100.

[0030] The first communication device 22 of the median strip 200 and the second communication devices 23L and 23R of the vehicle 100 are configured to be able to communicate with each other. More specifically, the second communication devices 23L and 23R transmit the identification information of the vehicle to the first communication device 22.

[0031] Here, the second communication devices 23L and 23R are communication devices having directivity. Since the second communication device 23L is provided on the left side of the vehicle 100, it transmits the identification information of the vehicle 100 toward the left side from the vehicle 100. The second communication device 23R transmits the identification information of the vehicle 100 toward the right side of the vehicle 100.

[0032] That is, 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] And when the first communication device 22 receives the identification information of the vehicle 100 from the second communication device 23L, it transmits the folded-back information to the second communication device 23L. Also, when the first communication device 22 receives information from the second communication device 23R, it transmits the folded-back information to the second communication device 23R.

[0034] The folded-back 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 a plurality of median strips are arranged on the road, it is necessary to clarify which second communication device of which vehicle and which communication device of which median strip form the communication network. By the second communication device transmitting the identification information of the vehicle to the first communication device and the first communication device transmitting the folded-back information to the second communication device, it is possible to clarify that it is the communication between the second communication device of a specific vehicle and the first communication device of a specific median strip.

[0035] In this way, the first communication device 22 and the second communication devices 23L and 23R use the identification information of the vehicle 100 and the folded-back information for communication. Since the amount of data of the identification information of the vehicle 100 and the folded-back information is small, in the information processing system 30, the communication time between the first communication device 22 and the second communication devices 23L and 23R can be shortened. Also, in the information processing system 30, by shortening the communication time between the first communication device 22 and the second communication devices 23L and 23R, communication with a plurality of vehicles becomes possible.

[0036] The notification unit 24 is a device provided in the vehicle, for example, a navigation device or a drive recorder. The notification unit 24, for example, warns the driver of the vehicle by voice that the vehicle is going in reverse.

[0037] <Control Unit> When the second communication device 23L or 23R receives the turning-back information from the first communication device 22, the control unit 21 controls the notification unit 24. This will be described in more detail with reference to FIGS. 4 to 7. FIGS. 4 and 5 are explanatory diagrams when the control unit controls the notification unit. FIGS. 6 and 7 are data flow diagrams between the first communication device and the second communication device. In FIGS. 4 and 5, the driving direction of the lane is indicated by an arrow. In FIGS. 4 and 5, the vehicle 101 includes the notification unit 24. Note that in FIGS. 4 to 7, the control unit 21 is not shown.

[0038] <Control when not going in reverse> First, an example will be described in which the control unit 21 controls so that the notification unit 24 does not issue a warning when the second communication device 23R receives the turning-back information from the first communication devices 22a and 22b, with reference to FIGS. 4 and 6.

[0039] As shown in FIG. 4, the vehicle 101 includes the second communication device 23R on the right side and the second communication device 23L on the left side. The vehicle 101 makes a left turn along the trajectory C1 and passes through such that the median strip 201 is on the right side as seen from the driver of the vehicle 101. As shown in FIG. 4, when the vehicle 101 makes a left turn along the trajectory C1, since it is in the same direction as the driving direction of the lane, it is not going in reverse.

[0040] As shown in FIG. 4, when the vehicle 101 starts to make a left turn along the trajectory C1, as shown in FIG. 6, the second communication device 23R and the second communication device 23L transmit the identification information S1 and S2 of the vehicle 101 to the first communication device 22a of the median strip 201.

[0041] Since the first communication device 22a is located on the right side as seen from the driver of the vehicle 100, it receives the identification information S1 of the vehicle 101 from the second communication device 23R. Also, since the first communication device 22a is located on the right side as seen from the driver of the vehicle 100, it does not receive the identification information S2 of the vehicle 101 from the second communication device 23L.

[0042] The first communication device 22a transmits, as the turning-back information S3, the information obtained by attaching the identification information of the median strip 201 to the identification information of the vehicle 101 to the second communication device 23R. From this, the second communication device 23R receives the turning-back information S3 from the first communication device 22a. Since the second communication device 23R has received the turning-back information from the first communication device 22a, the control unit 21 determines that the vehicle 101 is not running in reverse. Then, the control unit 21 controls the notification unit 24 not to issue a warning.

[0043] On the other hand, since the first communication device 22a does not receive the identification information S2 of the vehicle 101 from the second communication device 23L, it does not transmit the turning-back information S3 to the second communication device 23L.

[0044] Also, as shown in FIG. 4, the vehicle 101 turns right along the trajectory C2 and passes through such that the median strip 202 is on the right side as seen from the driver of the vehicle 101. As shown in FIG. 4, when the vehicle 101 turns right along the trajectory C2, since it is in the same direction as the driving direction of the lane, it is not running in reverse.

[0045] Also in this case, similar to the case of a left turn described above, since the first communication device 22b of the median strip 202 is located on the right side as seen from the driver of the vehicle 101, it receives the identification information S1 of the vehicle 101 from the second communication device 23R. The second communication device 23R receives the turning-back information S3 from the first communication device 22b. Since the second communication device 23R has received the turning-back information from the first communication device 22b, the control unit 21 determines that the vehicle 101 is not running in reverse. Then, the control unit 21 controls the notification unit 24 not to issue a warning.

[0046] <Control in the case of running in reverse> Next, with reference to FIGS. 5 and 7, an example will be described in which the control unit 21 controls the notification unit 24 to issue a warning when the second communication device 23L receives the turning-back information from the first communication devices 22a and 22b.

[0047] As shown in FIG. 5, the vehicle 101 is provided with a second communication device 23R on the right side and a second communication device 23L on the left side. The vehicle 101 turns left along the trajectory C3 and passes through such that the median strip 201 is on the left side as seen from the driver of the vehicle 101. As shown in FIG. 4, when the vehicle 101 turns left along the trajectory C3, since it is in the opposite direction to the driving direction of the lane, it is running in reverse.

[0048] As shown in FIG. 5, when the vehicle 101 starts to turn left along the trajectory C3, as shown in FIG. 6, the second communication device 23R and the second communication device 23L transmit the identification information S1, S2 of the vehicle 101 to the first communication device 22a of the median strip 201.

[0049] Since the first communication device 22a is located on the left side as seen from the driver of the vehicle 100, it receives the identification information S2 of the vehicle 101 from the second communication device 23L. Also, since the first communication device 22a is located on the left side as seen from the driver of the vehicle 100, it does not receive the identification information S1 of the vehicle 101 from the second communication device 23R.

[0050] The first communication device 22a transmits, as the return information S3, the information obtained by attaching the identification information of the median strip 201 to the identification information of the vehicle 101 to the second communication device 23L. From this, the second communication device 23L receives the return information S3 from the first communication device 22a. Since the second communication device 23L has received the return information from the first communication device 22a, the control unit 21 determines that the vehicle 101 is running in reverse. Then, the control unit 21 controls the notification unit 24 to give a warning.

[0051] On the other hand, since the first communication device 22a does not receive the identification information S1 of the vehicle 101 from the second communication device 23R, it does not transmit the return information S3 to the second communication device 23R.

[0052] Also, as shown in FIG. 5, the vehicle 101 turns right along the trajectory C4 and passes through such that the median strip 202 is on the right side as seen from the driver of the vehicle 101. As shown in FIG. 4, when the vehicle 101 turns right along the trajectory C4, since it is in the opposite direction to the driving direction of the lane, it is running in reverse.

[0053] Also in this case, similar to the left-turn case described above, since the first communication device 22b of the median strip 202 is located on the left when viewed from the driver of the vehicle 101, it receives the identification information S1 of the vehicle 101 from the second communication device 23L. The second communication device 23L receives the turning-back information S3 from the first communication device 22b. Since the second communication device 23L has received the turning-back information from the first communication device 22a, the control unit 21 determines that the vehicle 101 is running in reverse. Then, the control unit 21 controls the notification unit 24 to issue a warning.

[0054] In this way, when the second communication device 23L receives the turning-back information from the first communication devices 22a and 22b, the control unit 21 determines that the vehicle 101 is running in reverse and controls the notification unit 24 to issue a warning. When the second communication device 23R receives the turning-back information from the first communication devices 22a and 22b, the control unit 21 determines that the vehicle 101 is not running in reverse and controls the notification unit 24 not to issue a warning.

[0055] Generally, running in reverse at an intersection with a median strip occurs due to an artificial misrecognition of the driving direction of the lane. If the driver continues driving without noticing the reverse driving, it may lead to a major accident. However, as described above, the information processing system 30 determines whether the vehicle is running in reverse based on the transmission and reception state between the first communication device and the second communication device by the control unit 21, and controls the notification unit 24. With such a configuration, the information processing system 30 can notify the driver of running in reverse at an intersection with a median strip, so that the driver can promptly take accident avoidance actions.

[0056] In addition, since the information processing system 30 is configured to include a first communication device in the vehicle and a second communication device in the median strip, it has a simple configuration. In other words, the information processing system 30 constructs a simple communication network between the vehicle and the median strip. Furthermore, it only includes a second communication device in the median strip, and without requiring large-scale construction, the structure of the intersection becomes a simple structure. Therefore, the information processing system 30 can notify the driver of the reverse driving of the vehicle with a simple configuration.

[0057] Note that in FIGS. 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 at which the second communication device 23R transmits the vehicle identification information S1 and the timing at which the second communication device 23L transmits the vehicle identification information S2 may be the same, or may be in any order before or after.

[0058] <Control Timing> Next, the timing at which the control unit 21 controls the notification unit 24 will be described. The control unit 21 controls the notification unit based on the transmission and reception states between the first communication device 22 and the second communication devices 23L and 23R until the vehicle turns right or left at an intersection with a median strip.

[0059] Further, the control unit 21 may control the notification unit based on the transmission and reception states between the first communication device 22 and the second communication devices 23L and 23R when the vehicle starts to turn right or left at an intersection with a median strip. That is, the control unit 21 controls the notification unit 24 based on the transmission and reception states between the first communication device 22 and the second communication devices 23L and 23R from when the vehicle starts to turn right or left until it completes the right or left turn at an intersection with a median strip.

[0060] A more specific description will be given with reference to FIG. 8. FIG. 8 is an explanatory diagram of the timing at which the control unit controls the notification unit. The configurations of the vehicle 101 and the median strip 201 shown in FIG. 8 are the same as those shown in FIG. 5. In FIG. 8, the vehicle 101 includes the notification unit 24. Note that in FIG. 8, the control unit 21 is not shown. FIG. 8 corresponds to the left turn operation of the vehicle 101 along the trajectory C3 in FIG. 5.

[0061] As shown in FIG. 8, an example in which the control unit 21 controls the notification unit 24 based on the transmission and reception states between the first communication device and the second communication device at point A1 or point A2 when the vehicle 101 turns left along the trajectory C3 and drives in reverse on the road will be described. Point A1 is the point where the vehicle starts to turn left. Point A2 is the point where the vehicle completes the left turn. Note that the description will be made with reference to the data flow diagram shown in FIG. 7 as appropriate.

[0062] <Location A2> When the vehicle completes a left turn at the location A2 shown in FIG. 8, the second communication devices 23R and 23L transmit the identification information S1, S2 (see FIG. 7) of the vehicle 101 to the first communication device 22a in the median strip 201.

[0063] The first communication device 22a receives the identification information S2 (see FIG. 7) of the vehicle 101 from the second communication device 23L. Then, the first communication device 22a transmits, as the folded-back information S3 (see FIG. 7), the information obtained by attaching the identification information of the median strip 201 to the identification information of the vehicle 101 to the second communication device 23L (see FIG. 7). Thereby, since the second communication device 23L receives the folded-back information from the first communication device 22a, the control unit 21 determines that the vehicle 101 is running in reverse. Then, the control unit 21 controls the notification unit 24 to give a warning.

[0064] Although not shown in FIG. 8, similarly, when the vehicle 101 is not running in reverse on the road, the control unit 21 controls the notification unit 24 not to give a warning based on the transmission and reception state between the first communication device and the second communication device at the left-turn completion point.

[0065] That is, the control unit 21 controls the notification unit 24 based on the transmission and reception state between the first communication device and the second communication device at the point A2 where the vehicle completes a left turn. Thereby, since the information processing system 30 notifies the driver of the reverse running after the vehicle 101 enters the lane having the running direction opposite to the traveling direction, the driver can take accident avoidance actions such as stopping the vehicle 101.

[0066] Of course, similarly, when the vehicle starts a right turn, the control unit 21 controls the notification unit 24 based on the transmission and reception state between the first communication device and the second communication device at the point where the vehicle completes a right turn.

[0067] <Location A1> When the vehicle 101 starts to turn left at point A1 shown in FIG. 8, the second communication devices 23R and 23L transmit the identification information S1, S2 (see FIG. 7) of the vehicle 101 to the first communication device 22a of the median strip 201.

[0068] The first communication device 22a receives the identification information S2 (see FIG. 7) of the vehicle 101 from the second communication device 23L. Then, the first communication device 22a transmits the information obtained by attaching the identification information of the median strip 201 to the identification information of the vehicle 101 as the feedback information S3 (see FIG. 7) to the second communication device 23L (see FIG. 7). Thereby, since the control unit 21 determines that the vehicle 101 is running in reverse because the second communication device 23L has received the feedback information from the first communication device 22a, the control unit 21 controls the notification unit 24 to issue a warning.

[0069] Although not shown in FIG. 8, similarly, when the vehicle 101 is not running in reverse on the road, the control unit 21 controls the notification unit 24 not to issue a warning based on the transmission and reception state between the first communication device and the second communication device at the left-turn start point.

[0070] That is, the control unit 21 controls the notification unit 24 based on the transmission and reception state between the first communication device and the second communication device at the point A1 where the vehicle starts to turn left. Thereby, since the information processing system 30 can notify the driver of running in reverse at an intersection with a median strip at an earlier timing, the driver can promptly take accident avoidance actions.

[0071] Of course, similarly, when the vehicle starts to turn right, the control unit 21 controls the notification unit 24 based on the transmission and reception state between the first communication device and the second communication device at the point where the vehicle starts to turn right.

[0072] Here, an example in which the control unit 21 controls the notification unit 24 based on the transmission and reception states between the first communication device and the second communication device at location A1 or location A2 has been described. However, the present invention is not limited to this, and the control unit 21 may control the notification unit 24 based on the transmission and reception states between the first communication device and the second communication device at any location between location A1 and location A2 on the locus C3.

[0073] Note that the vehicle 101 acquires information regarding the steering operation for the start or completion of a right turn or a left turn of the vehicle 101. The second communication device 23L or 23R of the vehicle 101 transmits the identification information of the vehicle to the first communication device 22 based on the information regarding the steering operation.

[0074] For example, the second communication device 23L or 23R recognizes the timing when the driver turns the steering wheel to the left as the timing of starting a left turn, and transmits the identification information of the vehicle to the first communication device 22. In response to this, as described above, the control unit 21 controls the notification unit 24.

[0075] As another example, the second communication device 23L or 23R recognizes the timing when the driver returns the steering wheel from the left side to the original state as the timing of completing a left turn, and transmits the identification information of the vehicle to the first communication device 22. In response to this, as described above, the control unit 21 controls the notification unit 24.

[0076] <Installation of the Second Communication Device> In the information processing system 30 described above, an example in which the second communication device 23L is provided on the left side of the vehicle and the second communication device 23R is provided on the right side of the vehicle has been described. However, the present invention is not limited to this, and in the information processing system 30, the second communication device 23L may be provided on the left side of the vehicle, and the second communication device 23R may not be provided on the vehicle.

[0077] Even with such a configuration, when the second communication device receives the turning-back information from the first communication device, the information processing system 30 determines that the vehicle is running in reverse and controls the notification unit to issue a warning. Also, since the second communication device 23R of the vehicle becomes unnecessary, costs can be reduced. Therefore, the information processing system 30 can notify the driver of the vehicle running in reverse with a simple and low-cost configuration.

[0078] In Japan, since driving is on the left side, when running in reverse, the median strip is on the left side when viewed from the vehicle's driving position. Therefore, the second communication device 13 is preferably provided on the left side of the vehicle. On the other hand, in foreign countries where driving is on the right side, such as the United States, when running in reverse, the median strip is on the right side when viewed from the vehicle's driving position. Therefore, the second communication device 13 is preferably provided on the right side of the vehicle.

[0079] Note that the information processing device is not limited to being an ECU and may be provided in a drive recorder. Also, as shown in FIG. 3, the vehicle 100 typically includes the information processing device 20. However, it is not limited to this, and the vehicle 100 may be configured not to include the information processing device 20 but to include a server capable of communicating with the vehicle 100 and the median strip 200. In this case, the server includes the control unit 21. That is, the processing of the control unit 21 may be executed in the server.

[0080] <Information Processing Method> Subsequently, the information processing method according to the present disclosure will be described. FIG. 9 is a flowchart showing the information processing method according to the present disclosure.

[0081] As shown in FIG. 9, when the vehicle starts to turn right or left (step ST01), the second communication devices provided on the left and right sides of the vehicle transmit the vehicle's identification information to the first communication device (step ST02).

[0082] Next, the first communication device transmits, as turning-back information, the information obtained by attaching the identification information of the median strip to the vehicle's identification information received from the second communication device to the first communication device (step ST03).

[0083] Next, the control unit determines whether the number of communications of the first communication device and the second communication device is equal to or less than a predetermined number (step ST04). When the number of communications of the first communication device and the second communication device is equal to or less than the predetermined number (step ST04 YES), the control unit determines whether the second communication device on the left has received the folding information (step ST05).

[0084] On the other hand, when the number of communications of the first communication device and the second communication device is not equal to or less than the predetermined number (step ST04 NO), the control unit determines that the communications of the first communication device and the second communication device are abnormal and ends. In this way, the control unit has a timeout function based on the number of communications of the first communication device and the second communication device.

[0085] When the control unit determines that the second communication device on the left has received the folding information (step ST05 YES), it determines that the vehicle is reversing and controls the notification unit 24 to give a warning (step ST07).

[0086] On the other hand, when the control unit does not determine that the second communication device on the left has received the folding information (step ST05 NO), it determines whether the second communication device on the right has received the folding information (step ST06).

[0087] When the control unit determines that the second communication device on the right has received the folding information (step ST06 YES), it determines that the vehicle is not reversing and controls the notification unit 24 not to give a warning (step ST08).

[0088] When the control unit does not determine that the second communication device on the right has received the folding information (step ST06 NO), it repeats the process from step ST2.
