Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when a vehicle with passengers such as a bus is in operation, for example, at a timing such as from when the close switch of the door leading to the passenger compartment is operated until the vehicle departs, the driver's confirmation work of the vehicle is concentrated. That is, during this timing, from when the close switch of the door is operated until the door closes, the driver checks the side (for example, the left side) on the side where the door is provided among the left and right sides of the vehicle to confirm whether there is a passenger left behind, checks the center mirror of the vehicle to confirm whether there is a passenger running in from behind, and checks the left side again to confirm whether the running-in passenger actually gets on the vehicle.

[0005] Furthermore, between the closing of the doors and departure, the driver needs to check the central mirror to confirm the movements of passengers inside the passenger compartment, check the right side of the vehicle to check the conditions of merging lanes, and check the left side again to confirm that no passengers have been missed. Moreover, immediately after departure, the driver needs to start driving slowly while turning the steering wheel and checking the right side, and then check the left side again to confirm that no passengers have been missed.

[0006] Therefore, it is necessary to improve safety at times when vehicle crew members, such as drivers, are being checked intensively.

[0007] Therefore, this disclosure aims to provide an information provision device and information provision method that can improve safety at times when crew members are concentrated on verification work. [Means for solving the problem]

[0008] The information providing device relating to this disclosure is [1] "an information providing device for providing information to the crew of a vehicle equipped with a passenger compartment, comprising: a camera provided on one of the left or right sides of the vehicle; a display device provided on the other of the left or right sides of the vehicle that displays information corresponding to the image acquired by the camera; and a control unit that controls the camera and the display device, wherein one of the sides of the vehicle is provided with a door leading to the passenger compartment, and the other side of the vehicle is provided with a side mirror, the camera acquires an image of the area outside the vehicle including the door, the display device is provided in a position that can be seen by the crew of the vehicle at the same time as the side mirror, and the control unit includes a first display unit that, when it detects a first trigger after the vehicle has stopped, starts displaying the image acquired by the camera on the display device, and a second display unit that, when it detects a second trigger after the first trigger, causes the display device to display warning information to alert the crew that a person has been detected in the image."

[0009] In the information provision device described in [1] above, a display device is installed on one of the vehicle's left or right sides, on the side opposite to the side where the door leading to the passenger compartment and the camera are installed (hereinafter, for example, the left side) (hereinafter, for example, the right side), in a position that can be seen by the vehicle's crew (e.g., the driver) at the same time as the side mirror. When a first trigger is detected after the vehicle has stopped, the display device starts displaying the video acquired by the camera. If a second trigger is detected after the first trigger, and a person is detected in the video, alert information is displayed on the display device to notify the crew that a person has been detected.

[0010] Therefore, according to the information provision device described in [1] above, for example, between the time the door closing switch is operated and the door closes, the crew can obtain information that helps confirm whether or not a passenger has been missed by checking the image displayed on the display device located on the right side. In addition, after checking the mirror in the center of the vehicle to see if or not a passenger has rushed in from the rear of the vehicle, the crew can obtain information that helps confirm whether or not the rushing passenger will actually board the vehicle by checking the display device on the right side.

[0011] Furthermore, for example, between the closing of the doors and departure, the crew can check the right-side mirror to confirm the situation of the merging lane, and at the same time check the display device, thereby obtaining information that helps confirm whether any passengers have been missed. Moreover, immediately after departure, the crew can check the display device while turning the steering wheel and starting to drive slowly, while simultaneously checking the right side, thereby receiving assistance in confirming whether any passengers have been missed.

[0012] Thus, the information provision device described in [1] above can reduce the amount of eye movement required by the crew during times when their checking work is concentrated, thereby improving safety. Furthermore, the information provision device described in [1] above displays camera footage and warning information on the display device when a specific trigger is detected after the vehicle has stopped. This prevents the vehicle crew from having to constantly perform checking work based solely on the information displayed on the display device, and allows them to receive appropriate safety check assistance during times when their checking work is concentrated.

[0013] The information providing device relating to this disclosure may also be [2] "the information providing device described in [1] above, wherein the first trigger is the operation of the door open switch, and the second trigger is the operation of the door close switch." In this case, it becomes possible to improve safety at a more appropriate time when verification work is concentrated.

[0014] The information providing device relating to this disclosure may also be [3] "the information providing device according to [1] or [2] above, wherein the control unit includes a zone setting unit that sets a first zone including the door and a second zone including the first zone and wider than the first zone for the area captured by the camera, and the second display unit causes the display device to display different warning information depending on whether a person is detected inside the first zone or outside the first zone but inside the second zone." In this case, it becomes possible for the crew to easily determine, based on the warning information, whether a person is detected in the first zone where greater safety considerations are needed or in the second zone which is considered relatively safe.

[0015] The information providing device relating to this disclosure may also be [4] "the information providing device according to any of [1] to [3] above, wherein the first display unit inverts left and right to display the image on the display device." In this case, mistakes or confusion by crew members regarding left and right are suppressed.

[0016] The information providing device relating to this disclosure may also be [5] "the information providing device according to any of [1] to [4] above, wherein the control unit includes a first receiving unit that receives input for changing at least one of the first trigger, the second trigger, the display mode of the video, and the display mode of the warning information." In this case, it becomes possible to obtain safety confirmation assistance that meets the needs of the vehicle operator and crew.

[0017] The information providing device relating to this disclosure may also be the information providing device described in [3] above, wherein the control unit includes a second receiving unit that receives input for changing at least one of the first zone and the second zone. In this case, it becomes possible to obtain safety confirmation assistance that meets the needs of the vehicle operator and crew.

[0018] The information provision method relating to this disclosure is [7] "an information provision method for providing information to the crew of a vehicle equipped with a passenger compartment, comprising a display step of acquiring an image with a camera provided on one of the left or right sides of the vehicle, and displaying information corresponding to the image on a display device provided on the other of the left or right sides of the vehicle, wherein one side of the vehicle is provided with a door leading to the passenger compartment, the other side of the vehicle is provided with a side mirror, the camera acquires an image of the area outside the vehicle including the door, the display device is provided in a position where it can be seen by the crew of the vehicle at the same time as the side mirror, and the display step comprises a first display step of starting to display the image acquired by the camera on the display device when a first trigger is detected after the vehicle has stopped, and a second display step of displaying alert information on the display device to alert the crew that a person has been detected when a person is detected in the image when a second trigger is detected after the first trigger."

[0019] According to the information provision method described in [7] above, safety can be improved at times when crew members are concentrated on verification work, similar to the information provision device described in [1] above.

Advantages of the Invention

[0020] According to the present disclosure, it is possible to provide an information providing device and an information providing method capable of improving safety at a timing when the crew's confirmation work is concentrated.

Embodiments for Carrying Out the Invention

[0022] Hereinafter, an embodiment will be described with reference to the drawings. In the description of each figure, the same or corresponding elements are denoted by the same reference numerals, and redundant descriptions are omitted.

[0023] Figure 1 is a schematic plan view showing the information providing device and vehicle according to this embodiment. Figure 2 is a diagram showing a part of the interior of the vehicle shown in Figure 1. Figure 3 is a functional block diagram showing the information providing device shown in Figure 1. As shown in Figures 1 to 3, the information providing device 1 is mounted on vehicle B. Vehicle B includes a passenger compartment B1 for accommodating passengers, a door B1a leading to the passenger compartment B1, a workspace B2 for the crew member D1 involved in the operation of vehicle B, a side mirror B3, and a mirror B4. For example, vehicle B is a bus, crew member D1 is the driver of the bus, and workspace B2 is the driver's seat.

[0024] Door B1a is located on one of the sides of vehicle B (in this case, the left side). Door B1a is, for example, a middle door and is located near the center of vehicle B in the front-to-rear direction. The workspace B2 and side mirror B3 are located on the other side of vehicle B (in this case, the right side). The workspace B2 and side mirror B3 are located on the front part of vehicle B. Mirror B4 is located near the center of vehicle B in the left-to-right direction and on the front part of vehicle B.

[0025] Note that the left and right sides of vehicle B are based on the direction of travel T of vehicle B being forward, and the left and right sides refer to the left and right sides of the center line CL of vehicle B along the direction of travel T (forward and backward direction), regardless of whether they are inside or outside vehicle B. For example, side mirror B3 is installed on the outside of vehicle B, and mirror B4 is installed on the inside of vehicle B.

[0026] Information provision device 1 is for providing information to the crew member D of vehicle B. Information provision device 1 comprises a camera 10, a display terminal (display device) 20, and a control unit 30. Camera 10 is installed on one side of vehicle B where door B1a is located (in this case, the left side). Camera 10 is installed on the outside of vehicle B as an example. Camera 10 acquires images of the area AR on the outside of vehicle B, including door B1a (the left side of vehicle B).

[0027] The display terminal 20 is located on the side of vehicle B other than the side mirror B3 (in this case, the right side). The display terminal 20 is, in one example, located inside vehicle B. Specifically, the display terminal 20 is positioned so that it is visible to the crew member D sitting in the work area B2, simultaneously with the side mirror B3 (see Figure 2). In the example in Figure 2, both the display terminal 20 and the side mirror B3 are located at approximately the same vertical position on the pillar B13 between the front windshield B11 and the side window B12 of vehicle B. In the illustrated example, the display terminal 20 is contained within the width of the pillar B13, at least from the perspective of the crew member D sitting in the work area B2. This prevents the crew member D's field of view from being narrowed.

[0028] The display terminal 20 may be, for example, a tablet or a smartphone. Alternatively, the display terminal 20 may be an electronic mirror. If the display terminal 20 is an electronic mirror, it is also possible to display the field of view of the side mirror B3. Furthermore, if the display terminal 20 is a tablet or a smartphone, the display terminal 20 may be covered by a separate enclosure or the like. This is to avoid causing discomfort to passengers by installing a tablet or smartphone that can be operated by the crew member D around the work area B2.

[0029] The display terminal 20 displays information corresponding to the video acquired by the camera 10. This information includes the video itself, the video obtained by flipping the image horizontally (as described later), and warning information generated based on the video.

[0030] The control unit 30 is for controlling the camera 10 and the display terminal 20. The control unit 30 includes a first display unit 31, a second display unit 32, a first reception unit 33, a second reception unit 34, and a zone setting unit 35. The control unit 30 may be composed of a computer equipped with, for example, memory such as RAM or ROM, a processor (arithmetic circuit) such as a CPU, a communication interface, and storage such as a hard disk. The control unit 30 may be configured in the display terminal 20 if the display terminal 20 is a tablet or smartphone, or it may be configured in another terminal mounted on vehicle B. When the display terminal 20 is a tablet or smartphone and the control unit 30 is configured in the display terminal 20, installation is simpler and implementation is easier.

[0031] Next, the operation of each part of the control unit 30 will be explained by describing the information provision method according to this embodiment. Figure 4 is a flowchart of one step of the information provision method according to this embodiment. As shown in Figure 4, in this method, first the control unit 30 determines whether or not it has detected a first trigger after the vehicle B has stopped (for example, at a bus stop) (step S101).

[0032] For example, whether or not vehicle B has stopped at a bus stop may be determined by the control unit 30 based on GPS information and vehicle speed information, or by the control unit 30 detecting guardrails, bus stops, utility poles, etc., through image detection based on the video from camera 10. Also, the first trigger may be, for example, the operation of the open switch of door B1a. In this case, the first trigger is detected by the control unit 30 when the driver D of vehicle B operates the close switch of door B1a.

[0033] If the control unit 30 determines in step S101 that it has not detected the first trigger after vehicle B has stopped (step S101: NO), it repeats the determination in step S101 at predetermined intervals. At this time, the control unit 30 can maintain a state in which it does not display information based on the image from camera 10 on the display terminal 20, such as by blacking out the monitor 21 (see Figure 6) of the display terminal 20 until it detects the first trigger after vehicle B has stopped. This prevents the driver D of vehicle B from constantly having to perform verification work based only on the information displayed on the display terminal 20.

[0034] On the other hand, if the determination in step S101 indicates that the first trigger is detected after vehicle B has stopped (step S101: YES), the control unit 30 starts the system (step S102), and the first display unit 31 of the control unit 30 starts displaying the video acquired by camera 10 on the display terminal 20 (step S103: first display step). At this time, the first display unit 31 can reverse the left and right sides of the video acquired by camera 10 and display it on the display terminal 20.

[0035] As shown in Figure 1, the zone setting unit 35 of the control unit 30 can set a first zone Z1 including the door B1a and a second zone Z2 including the first zone Z1 and wider than the first zone Z1 for the area AR captured by the camera 10. For example, the first zone Z1 is the zone on the left side of vehicle B that does not reach the rear end of vehicle B, and the second zone Z2 is the zone on the left side and left rear of vehicle B that is wider than the first zone Z1 and extends beyond the rear end of vehicle B. The first zone Z1 and the second zone Z2 can be set to any size and shape.

[0036] The control unit 30 starts detecting people in the video at the same time as the video display terminal 20 starts displaying the video in step S103 (step S104). Figure 5 is a diagram showing an example of the video displayed on the display terminal. As shown in Figure 5, in step S104, people H1, H2, and H3 are detected in video P10. Bounding boxes K1, K2, and K3 are shown for each of people H1, H2, and H3.

[0037] In the next step, the control unit 30 determines whether or not a second trigger has been detected (step S105). One example of a second trigger is the operation of the close switch of door B1a. In this case, the control unit 30 detects the second trigger when the crew member D of vehicle B operates the close switch of door B1a.

[0038] If the control unit 30 determines that the second trigger is not detected as a result of the determination of process S105 (process S105: NO), it repeats the determination of process S105 at predetermined intervals.

[0039] On the other hand, if the second trigger is detected as a result of the determination in step S105 (step S105: YES), the second display unit 32 of the control unit 30 displays warning information on the display terminal 20 to alert the crew member D that a person has been detected in the video (step S106: second display step). As an example, the warning information is displayed by flashing the outer frame area 21b surrounding the central area 21a of the monitor 21 of the display terminal 20, as shown in Figure 6. At this time, in addition to displaying the warning information, the control unit 30 may also generate a warning sound from the display terminal 20.

[0040] Furthermore, the second display unit 32 can display different alert information on the display terminal 20 depending on whether a person is detected inside the first zone Z1 (first case) or outside the first zone Z1 but inside the second zone Z2 (second case).

[0041] More specifically, the second display unit 32 can differentiate the warning information so that in the first case, when a person is detected in the first zone Z1 near the door B1a, it provides a stronger warning than in the second case, when a person is detected in the second zone Z2 relatively far from the door B1a. One specific example of differentiating the warning information is that the second display unit 32 can shorten the flashing period of the outer frame area 21b in the first case compared to the flashing period of the outer frame area 21b in the second case, flash the outer frame area 21b in white in the second case while flashing it in yellow or red in the first case, or make the bounding box in the second zone Z2 white while making the bounding box in the first zone Z1 yellow or red. Another example is to display a frame-shaped image in the outer frame area 21b in the first case (to clearly indicate the outer frame area 21b), while not displaying the image in the outer frame area 21b in the second case.

[0042] In the next step, the control unit 30 determines whether or not door B1a is completely closed (step S107). If the result of the determination in step S107 is that the door is not completely closed (step S107: NO), the control unit 30 repeats the determination in step S107 at predetermined intervals.

[0043] On the other hand, if the result of the determination in step S107 is that door B1a is completely closed (step S107: YES), the control unit 30 further determines whether or not vehicle B has departed (step S108). If the result of the determination in step S108 is that vehicle B has not departed (step S108: NO), the control unit 30 repeats the determination in step S108 at predetermined intervals. The determination of whether or not vehicle B has departed may be made based on GPS information or vehicle speed information, or it may be made based on image detection based on the video from camera 10.

[0044] If the determination in step S108 indicates that vehicle B has departed (step S108: YES), the control unit 30 terminates the system (step S109) and blacks out the monitor 21 of the display terminal 20, thereby preventing the display terminal 20 from displaying information based on the image from camera 10 (step S110). This completes the process.

[0045] Furthermore, the first receiving unit 33 of the control unit 30 can receive input to change at least one of the following: the first trigger, the second trigger, the video display mode, and the display mode of the alert information. For example, as shown in Figure 6, the first receiving unit 33 can receive input to change the display magnification (e.g., wide-angle or magnified display) of the video acquired by the camera 10 by displaying information 22, 23 prompting the monitor 21 of the display terminal 20 to input the display magnification of the screen.

[0046] As another example, the first reception unit 33 can, as shown in Figure 7, display information 25, 26 prompting input for setting the colors of the first zone Z1 and the second zone Z2, or information 27-29 prompting input for setting the color of the bounding box, on the monitor 21 of the display terminal 20, thereby accepting input to change these settings as one of the methods of displaying prompt information.

[0047] Furthermore, as described above, the second receiving unit 34 of the control unit 30 can receive input to change the setting of at least one of the first zone Z1 and the second zone Z2, such as its position, size, or shape.

[0048] As described above, in the information provision device 1 and information provision method according to this embodiment, a display terminal 20 is provided on one of the left or right sides of the vehicle B, on the right side opposite to the left side where the door B1a leading to the passenger compartment B1 and the camera 10 are located, in a position that can be seen simultaneously by the crew member D of the vehicle B and the side mirror B3. When a first trigger is detected after the vehicle B has stopped, the display terminal 20 starts displaying the video acquired by the camera 10. Furthermore, if a second trigger is detected after the first trigger, and a person is detected in the video, alert information to notify the crew member D that a person has been detected is displayed on the display terminal 20.

[0049] Therefore, according to the information provision device 1 and information provision method, for example, in the time between the closing switch of door B1a being operated and door B1a closing, crew member D can obtain information that assists in confirming whether or not a passenger has been missed by checking the image displayed on the display terminal 20 located on the right side. Also, after checking the mirror B4 in the center of vehicle B to check whether or not a passenger has rushed in from the rear of vehicle B, crew member D can obtain information that assists in confirming whether or not the rushing passenger will actually board the vehicle by checking the display terminal 20 on the right side.

[0050] Furthermore, for example, between the closing of door B1a and departure, crew member D can check the right-side mirror B3 to confirm the situation of the merging lane, and at the same time check the display terminal 20, thereby obtaining information that helps confirm whether or not any passengers have been missed. Moreover, immediately after departure, crew member D can check the display terminal 20 at the same time as starting to drive slowly while turning the steering wheel and checking the right side, thereby receiving assistance in confirming whether or not any passengers have been missed. This allows them to notice if a passenger is rushing to board and prompt behavioral changes such as announcements to waiting passengers outside the vehicle or reopening the doors.

[0051] Thus, the information provision device 1 and information provision method make it possible to reduce the amount of eye movement of crew member D at times when confirmation work is concentrated, thereby improving safety. Furthermore, with the information provision device 1 and information provision method, when a specific trigger is detected after vehicle B has stopped, the image from camera 10 and warning information for caution are displayed on the display terminal 20. Therefore, it is possible to avoid a situation where crew member D of vehicle B always performs confirmation work using only the information displayed on the display terminal 20, and to obtain appropriate safety confirmation assistance at times when confirmation work is concentrated.

[0052] Furthermore, in the information providing device 1, the first trigger for the first display unit 31 to start displaying video on the display terminal 20 may be the operation of the open switch on door B1a. Also, in the information providing device 1, the second trigger for the second display unit 32 to start displaying warning information on the display terminal 20 may be the operation of the close switch on door B1a. In this case, it becomes possible to improve safety at a more appropriate timing when confirmation work is concentrated. In addition, in the information providing device 1, the area AR shooting by the camera 10 may be performed at all times regardless of whether the first trigger is detected or not, or it may be started after the first trigger is detected.

[0053] Furthermore, the information providing device 1 may include a zone setting unit 35 in the control unit 30 that sets a first zone Z1 including door B1a and a second zone Z2 including the first zone Z1 but wider than the first zone Z1 for the area AR captured by the camera 10. In this case, the second display unit 32 may display different warning information on the display terminal 20 depending on whether a person is detected inside the first zone Z1 or outside the first zone Z1 but inside the second zone Z2. In this case, the crew member D can easily determine, based on the warning information, whether a person is detected in the first zone Z1, where greater safety considerations are needed, or in the second zone Z2, which is considered relatively safer.

[0054] Furthermore, in the information provision device 1, the first display unit 31 may reverse the left and right orientation of the image acquired by the camera 10 and display it on the display terminal 20. In this case, mistakes or confusion by the crew member D regarding left and right are suppressed.

[0055] Furthermore, in the information providing device 1, the control unit 30 may include a first receiving unit 33 that receives input for changing at least one of the first trigger, the second trigger, the video display mode, and the warning information display mode. In this case, it becomes possible to obtain safety confirmation assistance that meets the needs of the vehicle operator and crew of vehicle B.

[0056] Furthermore, in the information provision device 1, the control unit 30 may include a second reception unit 34 that receives input for changing at least one of the first zone Z1 and the second zone Z2. In this case, it becomes possible to obtain safety confirmation assistance that meets the needs of the vehicle operator and crew member D of vehicle B.

[0057] The above embodiments describe one aspect of the present invention. Therefore, the present invention is not limited to the above-described information providing device 1 and information providing method, and can be modified as desired.

[0058] For example, the information provision device 1 and information provision method described above may also be applicable when vehicle B is a vehicle capable of at least partial autonomous driving. In this case, crew member D may not be the driver, and may not perform at least some of the driving operations of vehicle B.

[0059] Furthermore, in the information provision device 1 and information provision method described above, as stated above, the first receiving unit 33 is capable of receiving changes to the first trigger and the second trigger. Therefore, the first trigger is not limited to the operation of the open switch of door B1a, and the second trigger is not limited to the operation of the close switch of door B1a. Moreover, there may be two or more of at least one of the first trigger and the second trigger. If there are two or more first triggers (or second triggers), it may be a mandatory requirement to receive all of them, or it may be a requirement to receive at least one of them.

[0060] Furthermore, the alert information that the second display unit 32 displays on the display terminal 20 is not limited to the blinking of the outer frame area 21b of the monitor 21 of the display terminal 20, but can be anything.
