Description

Technical Field

[0001] This invention relates to an exterior display device for vehicles. Background Technology

[0002] Previously, when a driver was in a vehicle near a crosswalk, pedestrians wanting to cross the lane could predict whether the vehicle would stop before the crosswalk by making eye contact with the driver. However, with the increasing prevalence of autonomous vehicles, it is becoming more common for vehicles to cross crosswalks without a driver. In such cases, when a vehicle is autonomously approaching and near a crosswalk, pedestrians wanting to cross the lane may find it difficult to predict whether the vehicle will stop before the crosswalk. For example, Patent Document 1 discloses a technique for displaying stop warning information to pedestrians by illuminating the road surface when the vehicle is in autonomous driving mode.

[0005] Patent Document 1: International Publication No. 2017 / 073634 Summary of the Invention

[0006] The technical problem that the invention aims to solve

[0007] However, although the stop notification information in Patent Document 1 is intended for pedestrians located around the crosswalk, since pedestrians other than those around the crosswalk can also visually confirm the message, there is a possibility that pedestrians other than those around the crosswalk may mistakenly believe that the message is for them.

[0008] The present invention was made in view of the above circumstances, and its object is to provide an exterior display device capable of displaying information to a specific party based on the positional relationship between a pedestrian and the vehicle, and conveying useful information to that party.

[0009] Technical means for solving problems

[0010] To achieve the above objectives, the vehicle exterior display device of the present invention is characterized by comprising: a vehicle location information acquisition unit, which acquires the location information of the vehicle; a pedestrian crossing location information acquisition unit, which acquires the location information of a pedestrian crossing; a surrounding information detection unit, which detects pedestrians around the vehicle; a display unit, which has multiple display areas that can be visually confirmed from outside the vehicle, and can display different visually confirmable display information according to the display areas; and a display control unit, which controls the display information based on the vehicle and the pedestrians. The display control unit adjusts the display information displayed by the display unit and the display area displaying the information based on the positional relationship between the crosswalk and the pedestrian. The multiple display areas include at least a distant display area and a nearby display area. The display control unit causes the display area in the distant display area and the nearby display area, which is visually identifiable by pedestrians located around the crosswalk, to display information related to the vehicle's behavior. At least when the positional relationship between the vehicle and the pedestrians located around the crosswalk is distant, the display information displayed in the distant display area and the display information displayed in the nearby display area are different.

[0011] Invention Effects

[0012] The vehicle exterior display device involved in this invention has the following effect: it can display information to the intended recipient based on the positional relationship between the vehicle and the pedestrian, and convey useful information to the recipient.

[0048] V This vehicle Detailed Implementation

[0049] Hereinafter, embodiments of the vehicle exterior display device 1 according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to these embodiments.

[0050] [Implementation Method 1]

[0051] Figure 1 This is a diagram illustrating the vehicle exterior display device according to the present invention. Figure 2 This is a diagram illustrating an example of a method for setting the display area of ​​an external display device according to Embodiment 1. Figure 3 This is a diagram showing the structure of the display unit according to Embodiment 1. Figure 4-1 This is a diagram showing the display area and display information when the relative position of the vehicle and the pedestrian is at a distance according to Embodiment 1. Figure 4-2 This is a diagram showing the display area and display information when the relative positions of the vehicle and the pedestrian are in the vicinity according to Embodiment 1.

[0052] The external display device 1 is applied to vehicle V and is a display device used for various displays. The vehicle V using the external display device 1 can be any vehicle that uses an electric motor or engine as a drive source, such as an electric vehicle (EV), a hybrid electric vehicle (HEV), a plug-in hybrid electric vehicle (PHEV), a gasoline vehicle, or a diesel vehicle. Furthermore, the driving of this vehicle V can be any of the following: manual driving by a driver, semi-autonomous driving, or fully autonomous driving. Additionally, this vehicle V can also be any of the following: a privately owned car, a rental car, a shared car, a bus, a taxi, or a ride-sharing vehicle.

[0053] In the following description, as an example, we will explain the case where vehicle V is a vehicle capable of autonomous driving (semi-autonomous driving, fully autonomous driving). The external display device 1, based on the so-called autonomous driving achieved in vehicle V, displays appropriate information related to the vehicle's behavior according to the positional relationship between the external vehicle and a person. The external display device 1... Figure 1 The components shown are implemented by mounting them on vehicle V. Hereinafter, refer to... Figure 1 The structure of the external display device 1 will be described in detail. In the following description, the vehicle V will sometimes be referred to as "this vehicle V".

[0054] It should be noted that, in Figure 1 Unless otherwise specified, the connection method between the various components used for power supply, control signals, and the transmission and reception of various information in the vehicle external display device 1 shown can be any of the following: wired connection via wiring materials such as wires and optical fibers (e.g., optical communication via optical fibers), wireless communication, contactless power supply, etc., unless otherwise specified.

[0055] Specifically, the external display device 1 includes a detection unit 10, a display unit 20, and a control unit 30.

[0056] First, the inspection unit 10 will be explained. The inspection unit 10 will... Figure 1 The components shown are mounted on a vehicle V. Specifically, the detection unit 10 includes a GPS receiver 11, a driving system actuator 12, a vehicle status detection unit 13, a communication module 14, an external camera 15, and an external radar 16.

[0057] GPS receiver 11 detects the current position information, i.e., the vehicle's position information X1, representing the current position of vehicle V, as surrounding condition information. GPS receiver 11 obtains the GPS information (latitude and longitude coordinates) of vehicle V as its position information X1 by receiving radio waves transmitted from GPS satellites. Driving system actuator 12 consists of various devices used to move vehicle V. Driving system actuator 12 is typically configured to include a driving powertrain, a steering system, and a braking system. The driving powertrain is the drive unit that moves vehicle V. The steering system is the device that steers vehicle V. The braking system is the device that brakes vehicle V. Vehicle status detection unit 13 detects vehicle status information, including vehicle speed information, acceleration information, steering angle information, accelerator pedal operation amount information, brake pedal operation amount information, gear information, current / voltage value information, and battery charge information. Vehicle status detection unit 13 is composed of various detectors and sensors, such as a vehicle speed sensor, acceleration sensor, steering angle sensor, throttle sensor, brake sensor, gear sensor, and current / voltage meter. The vehicle status detection unit 13 may also include the processing unit itself, such as the ECU (Electronic Control Unit) that controls various parts of the vehicle V. The communication module 14 communicates with external devices of the vehicle V, such as other vehicles, roadside equipment, cloud devices, and electronic devices held by people outside the vehicle V, via wireless communication. Thus, the communication module 14 detects, for example, surrounding condition information including surrounding image information, external object information, traffic information, and the vehicle's location information X1. The communication module 14 communicates with external devices via various wireless communication methods, such as wide-area wireless and narrow-area wireless. Here, wide-area wireless methods include, for example, radio (AM, FM), TV (UHF, 4K, 8K), TEL, GPS, WiMAX (registered trademark), etc. In addition, narrow-area wireless methods include, for example, ETC / DSRC, VICS (registered trademark), wireless LAN, millimeter-wave communication, etc. The external camera 15 captures images of the surroundings of the vehicle V that constitute surrounding image information and images of the road surface on which the vehicle V travels that constitutes white line information as surrounding condition information. The external radar 16 uses infrared, millimeter wave, ultrasonic waves, etc., to detect external object information as surrounding condition information.

[0058] Display unit 20 is disposed on vehicle V and has multiple display areas E that can be visually confirmed from outside vehicle V. In this embodiment, it has two display areas E1 and E2, and the display information M that can be visually confirmed can be different depending on display areas E1 and E2. In this embodiment, display unit 20 is disposed outside or inside vehicle V in front of vehicle V and has: a distant display area E1, which is an area that displays information towards the far front of vehicle V, especially towards the far left when passing on the left; and a nearby display area E2, which is adjacent to the distant display area E1 and displays information towards the near front of vehicle V, especially towards the near left when passing on the left. Here, each display area E1 and E2 refers to the range of display that can be seen by only specific pedestrians, and is the display angle that can be displayed from display unit 20. In this embodiment, the display information M displayed in each display area E1 and E2 is changed according to the relative position of vehicle V and pedestrians 100 located around pedestrian crossing 200. For example, as Figure 2 The diagram illustrates the method for calculating the distance display area E1 assuming a vehicle traveling at 60 km / h on a normal road. The solid line S1 represents the deceleration curve of the vehicle V when it stops at a deceleration rate that will not cause discomfort to passengers, and the dashed line S2 represents the relationship between the distance the vehicle V stops by emergency braking and its speed. Assuming deceleration at a rate that will not cause discomfort to passengers, and starting the display on the display unit 20 25 meters before the stopping position, the distance the vehicle V stops by emergency braking at the initial stop speed is approximately 11 meters. If the direction of travel of the vehicle V is set to forward, and a pedestrian suddenly appears within 11 meters of the center section of the vehicle V in the left-right direction, a collision cannot be avoided; therefore, it is preferable that the pedestrian within this range is not visible. Based on this, the distance display area E1 is set based on equation (1).

[0059] Θ = arctan(H / K) × 180 / π

[0060] =arctan(3 / 11)×180 / π≒15.2…(1)

[0061] (Θ: Display angle (the angle between the vehicle and the forward direction V), H: Road width, K: Distance for emergency braking to a stop)

[0062] Furthermore, one method for determining Θ is to avoid limiting factors such as the coefficient of friction between the tires and the road surface, the assumed vehicle speed, deceleration, and the starting position of deceleration. Additionally, parameters that affect the safe stopping range of the vehicle, such as road conditions, weather, and the accuracy of various sensors, can also be considered. Furthermore, the unpleasant experience for passengers in an autonomous vehicle during deceleration can also be taken into account.

[0063] like Figure 3As shown, the display unit 20 includes a light-emitting unit 21, a lens 22, a cover 23, a housing 24, and a substrate 25. In this embodiment, the light-emitting units 21 are mounted on the substrate 25, and multiple units are arranged on a plane. The light-emitting units 21 in this embodiment are composed of multiple light-emitting unit groups 21a and 21b, each corresponding to a lens 22. The multiple light-emitting unit groups 21a and 21b are a first light-emitting unit group 21a corresponding to the distant display area E1 and a second light-emitting unit group 21b corresponding to the nearby display area E2. The first light-emitting unit group 21a is composed of multiple first light-emitting units 211, and the second light-emitting unit group 21b is composed of multiple second light-emitting units 212. The first light-emitting units 211 are arranged corresponding to each lens 22, and in this embodiment, they are arranged at the center relative to each lens 22. The second light-emitting units 212 are arranged corresponding to each lens 22, and in this embodiment, when adjacent to the first light-emitting units 211, they are arranged at one of the two ends relative to each lens 22. The first light-emitting unit group 21a and the second light-emitting unit group 21b are alternately arranged to emit light corresponding to the display information M about the behavior of the vehicle V. The display information M about the behavior of the vehicle V changes according to the display area E. Therefore, the first light-emitting unit group 21a and the second light-emitting unit group 21b emit light based on different display information M. Specifically, when the relative position of the vehicle V and the pedestrian 100 located around the pedestrian crossing 200 is at a distance, the first light-emitting unit group 21a, corresponding to the distant display area E1, emits light to display information M1 related to the future vehicle behavior corresponding to the distant position, and the second light-emitting unit group 21b, corresponding to the nearby display area E2, emits light to display information M2 related to the current vehicle behavior corresponding to the distant position. However, when the relative position of the vehicle V and the pedestrian 100 located around the crosswalk 200 changes to a nearby position, the information displayed in the information M that the pedestrian 100 wants to know about the behavior of the vehicle V differs from the information displayed when the relative position of the vehicle V and the pedestrian 100 is far away. Therefore, when the relative position of the vehicle V and the pedestrian 100 is changed to a nearby position, the first light-emitting unit group 21a corresponding to the far-away display area E1 illuminates the display information M4 related to future vehicle behavior corresponding to the nearby position, and the second light-emitting unit group 21b corresponding to the nearby display area E2 illuminates the display information M3 related to the current vehicle behavior corresponding to the nearby position. Thus, based on the positional relationship between the vehicle V and the pedestrians 100 located around the crosswalk 200, the first light-emitting unit group 21a and the second light-emitting unit group 21b emit light according to different display information M. The lens 22 has a semi-circular cross section, allowing light from the light-emitting unit 21 to pass through.Lens 22, depending on the viewing angle from outside the vehicle V, allows for visual confirmation of the different positions of the light source 21 through light refraction. Cover 23 is translucent, allowing for visual confirmation of the light source 21 from outside the vehicle V. Housing 24 surrounds the light source 21 and lens 22, with cover 23 embedded on the outer side of housing 24 of the vehicle V.

[0064] like Figure 1 As shown, the control unit 30 uniformly controls all parts of the external display device 1. The control unit 30 can also be combined with an electronic control unit that uniformly controls the entire vehicle V. The control unit 30 performs various computational processes to realize the driving of the vehicle V. The control unit 30 is configured to include electronic circuitry, primarily a known microcomputer including a CPU (Central Processing Unit), MPU (Micro Processing Unit), ASIC (Application Specific Integrated Circuit), FPGA (Field Programmable Gate Array), ROM (Read Only Memory), RAM (Random Access Memory), and interfaces. The control unit 30 is electrically connected to the detection unit 10 and the display unit 20. The control unit 30 can be electrically connected to the detection unit 10 and the display unit 20 via an ECU (e.g., a body ECU) that controls various parts in the vehicle V. The control unit 30 is capable of exchanging various detection signals and drive signals with each other, as well as other electrical signals, with each other.

[0065] Specifically, the control unit 30 is functionally configured to include an interface unit 31, a vehicle location information acquisition unit 32, a pedestrian crossing location information acquisition unit 33, a surrounding information acquisition unit 34, a display control unit 35, and a storage unit 36. The interface unit 31, the vehicle location information acquisition unit 32, the pedestrian crossing location information acquisition unit 33, the surrounding information acquisition unit 34, the display control unit 35, and the storage unit 36 ​​are capable of exchanging and receiving various information with electrically connected devices.

[0066] Interface unit 31 is an interface for sending and receiving various information with various units such as the detection unit. Furthermore, interface unit 31 is configured to be electrically connected to the detection unit 10, the vehicle location information acquisition unit 32, the pedestrian crossing location information acquisition unit 33, and the surrounding information acquisition unit 34. Interface unit 31 has the function of wired communication with each unit via wires or the like, and the function of wireless communication with each unit via a wireless communication unit or the like.

[0067] The vehicle location information acquisition unit 32 acquires the vehicle location information X1. The vehicle location information acquisition unit 32 acquires the vehicle location information X1, for example, based on information received by the GPS receiver 11.

[0068] The pedestrian crossing location information acquisition unit 33 acquires the location information of the pedestrian crossing 200. For example, based on the vehicle's location information X1 and map information pre-stored in the storage unit 36, the pedestrian crossing location information acquisition unit 33 acquires the location information of the pedestrian crossing 200 existing in the direction of travel of the vehicle V, namely, pedestrian crossing location information X2. Alternatively, the pedestrian crossing location information acquisition unit 33 may also acquire the pedestrian crossing location information X2 based on images of the surrounding area of ​​the vehicle V captured by the external camera 15. Furthermore, the pedestrian crossing location information acquisition unit 33 may also acquire the pedestrian crossing location information X2 based on the vehicle's location information X1 and map information stored outside the vehicle V obtained by the communication module 14.

[0069] The surrounding information acquisition unit 34 acquires information about the vicinity of the vehicle V. In this embodiment, the surrounding information acquisition unit 34 acquires information related to pedestrians 100 who are visually identified as objects by the display unit 20 around the vehicle V. For example, the surrounding information acquisition unit 34 may acquire pedestrian location information X3 existing around the vehicle V based on images of the vehicle V captured by the external camera 15. Alternatively, for example, pedestrian location information X3 may be acquired based on objects around the vehicle V scanned and detected by the external radar 16.

[0070] The display control unit 35 controls the display information M related to the behavior of the vehicle V displayed by the display unit 20 in the distant display area E1 and the nearby display area E2 of the display unit 20. In this embodiment, the display control unit 35 changes the display information M related to the behavior of the vehicle V in the display area E of the display unit 20 based on the positional relationship between the vehicle position information X1 obtained by the vehicle position information acquisition unit 32, the pedestrian crossing position information X2 obtained by the pedestrian crossing position information acquisition unit 33, and the pedestrian position information X3 obtained by the surrounding information acquisition unit 34, according to the relative position of the vehicle V and the surrounding pedestrians 100. Specifically, based on the pedestrian crossing position information X2 obtained by the pedestrian crossing position information acquisition unit 33 and the pedestrian position information X3 obtained by the surrounding information acquisition unit 34, the positional relationship between the pedestrian crossing 200 and the pedestrian 100 is calculated, and it is determined whether there is a pedestrian 100 around the pedestrian crossing 200, that is, whether the pedestrian 100 is located around the pedestrian crossing 200. Furthermore, regarding the determination that pedestrian 100 is located around pedestrian crossing 200, it can be determined by judging whether pedestrian 100's face and body are facing the direction of pedestrian crossing 200. If pedestrian 100 is facing the direction of pedestrian crossing 200, then pedestrian 100 is determined to be about to cross pedestrian crossing 200. Then, when it is determined that pedestrian 100 is located around the pedestrian crossing 200 and pedestrian 100 is about to cross the pedestrian crossing 200, the positional relationship between pedestrian 100 and vehicle V around the pedestrian crossing 200 is calculated based on the vehicle position information X1 obtained from the vehicle position information acquisition unit 32 and pedestrian position information X3 obtained from the surrounding information acquisition unit 34. If it is determined that the relative position between pedestrian 100 and vehicle V around the pedestrian crossing 200 is a distant position, display information M1 related to the future behavior of vehicle V corresponding to the distant position is displayed in the distant display area E1 of the display unit 20, and display information M2 related to the current behavior of vehicle V corresponding to the distant position is displayed in the nearby display area E2. Furthermore, based on the vehicle location information X1 obtained by the vehicle location information acquisition unit 32 and the pedestrian location information X3 obtained by the surrounding information acquisition unit 34, the positional relationship between the pedestrian 100 located around the pedestrian crossing 200 and the vehicle V is calculated. When it is determined that the relative position between the pedestrian 100 located around the pedestrian crossing 200 and the vehicle V is a nearby position, display information M3 related to the current behavior of the vehicle corresponding to the nearby position is displayed to the display unit 20 in the nearby display area E2, and display information M4 related to the future behavior of the vehicle corresponding to the nearby position is displayed in the distant display area E1.

[0071] For example, when vehicle V is traveling on road R, such as Figure 4-1As shown, the display control unit 35, based on the pedestrian crossing position information X2 obtained by the pedestrian crossing position information acquisition unit 33 and the pedestrian position information X3 obtained by the surrounding information acquisition unit 34, determines that the relative position of the pedestrian 100 located around the pedestrian crossing 200 and the vehicle V is at a distance. Therefore, as the display information M to be displayed in the distant display area E1 of the display unit 20, it displays "Stop," which is directed towards the pedestrian 100 located around the pedestrian crossing 200 and is related to future vehicle behavior. Thus, the pedestrian 100 located around the pedestrian crossing 200 and about to cross the pedestrian crossing 200 can visually confirm the display on the display unit 20. However, if other pedestrians 400 are located closer to the vehicle V than pedestrians 100 located around the crosswalk 200, even though the display is for pedestrians 100 around the crosswalk 200, pedestrians 400 located closer to the vehicle V might mistakenly perceive the display as directed at them. Therefore, in the nearby display area E2, for pedestrians 400 located closer to the vehicle V than pedestrians 100 around the crosswalk 200, a different display information M2 related to the current vehicle behavior, such as "passing," is displayed, which is different from the display information M for pedestrians 100 around the crosswalk 200. At this time, the first light-emitting unit group 21a emits light based on the display information M1 such as "stop," and the second light-emitting unit group 21b emits light based on the display information M2 such as "passing." Additionally, as... Figure 4-2 As shown, when an unmanned, autonomous vehicle V stops in front of pedestrian crossing 200, and... Figure 4-1 In contrast, the relative position of the vehicle V to the pedestrians 100 located around the crosswalk 200 changes to a more nearby position. Therefore, the display information M displayed in the display area E2 near the display unit 20 is displayed as "Parking", which is related to the current vehicle behavior and is directed towards the pedestrians 100 located around the crosswalk 200. Since pedestrians 500 who are farther away from the vehicle V than those 100 located around the crosswalk 200 will pay attention to the behavior of the autonomous vehicle, the display information M4 related to future vehicle behavior, such as "Starting", is displayed in the distant display area E1 that pedestrians 500 who are farther away from the vehicle V can visually confirm. At this time, the first light-emitting unit group 21a emits light based on the display information M4 such as "Starting", and the second light-emitting unit group 21b emits light based on the display information M3 such as "Parking".

[0072] Storage unit 36 ​​is a device for storing data related to the behavior of the vehicle. Storage unit 36 ​​can be, for example, a large-capacity storage device such as a hard disk, SSD (Solid State Drive), or optical disk, or a rewritable semiconductor memory such as RAM, flash memory, or NVSRAM (Non-Volatile Static Random Access Memory). Storage unit 36 ​​stores conditions, information, various programs, application programs, control data, etc., required for various processes in control unit 30. Storage unit 36 ​​may, for example, store display information M related to the behavior of the vehicle V on display unit 20 controlled by display control unit 35. In addition, storage unit 36 ​​can also temporarily store various information acquired by vehicle position information acquisition unit 32, pedestrian crossing position information acquisition unit 33, and surrounding information acquisition unit 34. Storage unit 36 ​​reads this information as needed through display control unit 35.

[0073] Next, the general operation of the external display device 1 will be explained. Figure 5 This is a flowchart illustrating an example of the control of the vehicle exterior display device according to Embodiment 1.

[0074] First, the display control unit 35 determines whether a pedestrian 100 exists in the vicinity of the pedestrian crossing 200 based on pedestrian location information X3 and pedestrian crossing location information X2 (step S1). Specifically, based on the pedestrian crossing location information X2 obtained by the pedestrian crossing location information acquisition unit 33 and the pedestrian location information X3 obtained by the surrounding information acquisition unit 34, the positional relationship between the pedestrian crossing 200 and the pedestrian 100 is calculated, and it is determined whether a pedestrian 100 intends to cross the pedestrian crossing 200. The display control unit 35 determines that the pedestrian 100 intends to cross the pedestrian crossing 200 if the pedestrian 100's face or body is facing the direction of the pedestrian crossing 200, or if the pedestrian 100's movement trajectory is oriented towards the pedestrian crossing 200.

[0075] If it is determined that there are no pedestrians 100 around the pedestrian crossing 200 (step S1: no), the display control unit 35 repeatedly performs step S1 until there are pedestrians 100 around the pedestrian crossing 200.

[0076] When it is determined that there is a pedestrian 100 in the vicinity of the pedestrian crossing 200 (step S1: yes), the display control unit 35 calculates the positional relationship between the vehicle V, the pedestrian crossing 200, and the pedestrian 100 based on the vehicle position information X1, the pedestrian crossing position information X2, and the pedestrian position information X3 (step S2).

[0077] Next, the display control unit 35 determines whether the vehicle V is approaching the pedestrian crossing 200 based on the vehicle location information X1 and the pedestrian crossing location information X2 (step S3).

[0078] When it is determined that the vehicle V is approaching the pedestrian crossing 200 (step S3: yes), the display control unit 35 determines whether the relative position of the vehicle V and the pedestrian 100 is far away based on the vehicle position information X1 and the pedestrian position information X3 (step S4).

[0079] If the relative position between the vehicle V and the pedestrian 100 is determined to be a distant position (step S4: Yes), the display control unit 35 displays display information M1 related to the future behavior of the vehicle at the distant position in the distant display area E1, and displays display information M2 related to the current behavior of the vehicle at the distant position in the nearby display area E2 (step S5). For example, the display control unit 35 causes the first light-emitting unit group 21a corresponding to the nearby display area E2 to illuminate and display the display information M1 related to the future behavior of the vehicle at the distant position, and displays display information M1 related to the future behavior of the vehicle, such as "stop," so that the pedestrian 100, which is located at a distant position relative to the vehicle V, can determine whether the vehicle V has recognized the pedestrian 100. However, if pedestrian 400 is located closer to vehicle V than pedestrian 100 located around pedestrian crossing 200, pedestrian 400 might mistakenly perceive the display as a display to themselves, even though it is unrelated to the display to pedestrian 100 located around pedestrian crossing 200. Therefore, the second light-emitting unit group 21b corresponding to the nearby display area E2 emits light to display information M2 related to the current vehicle behavior at a distant location, and displays "passing" in the nearby display area, which is different from the information displayed to pedestrian 400 other than those around pedestrian crossing 200 (see reference). Figure 4-1 ).

[0080] Next, the display control unit 35 calculates the positional relationship between the vehicle V, the pedestrian 100, and the crosswalk 200 (step S2). When it is determined that the vehicle V is approaching the crosswalk 200 (step S3: yes), it again determines whether the relative position of the vehicle V and the pedestrian 100 is a distant position (step S4). Therefore, when the pedestrian 100 is still a distant position relative to the vehicle V, the display control unit 35 maintains the distant display area E1 in the display state of display information M1 related to the future behavior of the vehicle V at the distant position, and maintains the nearby display area E2 in the display state of display information M2 related to the current behavior of the vehicle at the distant position.

[0081] Furthermore, if it is determined that the relative position between the vehicle V and the pedestrian 100 is not far away, that is, the relative position is nearby (step S4: No), the display control unit 35 causes the nearby display area E2 to display display information M3 related to the current behavior of the vehicle V at the nearby position, and causes the distant display area E1 to display display information M4 related to the future behavior of the vehicle at the nearby position (step S6). For example, the display control unit 35 illuminates the second light-emitting unit group 21b corresponding to the nearby display area E2 to display the display information M3 related to the current behavior of the vehicle at the nearby position, and displays the display information M3 related to the current behavior of the vehicle, such as "parking", so that the pedestrian 100, who is at the nearby position relative to the vehicle V, can determine whether he or she can cross the pedestrian crossing 200. Since the pedestrian 500, located far from vehicle V, will pay attention to the behavior of the autonomous vehicle, the second light-emitting unit group 21b corresponding to the distant display area E1 emits light to display information M4 related to future vehicle behavior in the vicinity. Within the distant display area E1, which the pedestrian 500 can visually confirm, information M4 related to future vehicle behavior, such as "starting," is displayed (see reference). Figure 4-2 ).

[0082] Next, the display control unit 35 determines whether there is a pedestrian 100 around the pedestrian crossing 200 based on the pedestrian crossing location information X2 and the pedestrian location information X3 (step S7). Here, the display control unit 35 determines whether the pedestrian 100 has crossed the pedestrian crossing 200.

[0083] Next, when the display control unit 35 determines that a pedestrian 100 exists in the vicinity of the pedestrian crossing 200 (step S7: Yes), it calculates the positional relationship between the vehicle V, the pedestrian 100, and the pedestrian crossing 200 (step S2), determines that the vehicle V is approaching the pedestrian crossing 200 (step S3: Yes), and determines that the relative position of the vehicle V and the pedestrian 100 is nearby (step S4: No). Therefore, while the pedestrian 100 is still nearby relative to the vehicle V, the display control unit 35 maintains the nearby display area E2 in the display state of display information M3 related to the current vehicle behavior at the nearby location, and maintains the distant display area E1 in the display state of display information M4 related to the future behavior of the vehicle at the nearby location.

[0084] Next, when it is determined that there are no pedestrians 100 around the pedestrian crossing 200 (step S7: no), the display control unit 35 ends the display of the display unit 20 (step S8).

[0085] In the vehicle exterior display device 1 described above, even if the relative position of the vehicle V and the pedestrian 100 changes, the pedestrian 100 located around the crosswalk 200 can always visually confirm the display of the display unit 20 and can visually confirm appropriate information related to the behavior of the vehicle V corresponding to the relative position of the vehicle V and the pedestrian 100. Furthermore, pedestrians 400 and 500 other than the pedestrian 100 located around the crosswalk 200 visually confirm display information M related to the behavior of the vehicle V that is different from that of the pedestrian 100 located around the crosswalk 200, and can therefore determine the behavior of the vehicle V based on the display information M related to the behavior of the vehicle V provided to them. Thus, pedestrians 400 and 500 other than the pedestrian 100 located around the crosswalk 200 can act based on the display information M related to the behavior of the vehicle V provided to them, thereby maintaining safety in relation to the vehicle V. That is, the external display device 1 can display information to the intended recipient based on the positional relationship between the vehicle V and pedestrians 100, 400, and 500, and convey useful information to the recipient.

[0086] Furthermore, the exterior display device 1 controls the illumination of the light-emitting unit 21 within the display unit 20 based on whether the relative position of the vehicle V to the pedestrians 100 located around the crosswalk 200 is either far away or nearby, thereby changing the display information M of the display area E of the display unit 20. As a result, the exterior display device 1 can set multiple display areas E1 and E2 within a single display unit 20.

[0087] In addition, the external display device 1 is equipped with multiple light-emitting units 21a and 21b corresponding to the distant display area E1 and the nearby display area E2, which are arranged in accordance with the relative positions of the vehicle V and the pedestrians 100 located around the pedestrian crossing 200. Different displays can be visually confirmed according to the viewing angle from outside the vehicle.

[0088] In this embodiment, the case with light-emitting part 21 and lens 22 has been described, but it is not limited to this. Figure 6This diagram illustrates the display unit involved in the modified example. The light-shielding member 26 has multiple openings 26a corresponding to each light-emitting unit 21. The openings 26a are formed such that pedestrians in the distant display area E1 and the nearby display area E2 cannot visually confirm the magnitude of light from the light-emitting unit group adjacent to the corresponding light-emitting unit group. In the modified example, the light-emitting unit 21 is composed of multiple light-emitting unit groups corresponding to the openings 26a. Each multiple light-emitting unit group consists of a first light-emitting unit group 21a corresponding to the distant display area E1 and a second light-emitting unit group 21b corresponding to the nearby display area E2, with the first light-emitting unit group 21a and the second light-emitting unit group 21b arranged alternately. Specifically, a pedestrian in the distant display area E1 can visually confirm the illumination of the corresponding first light-emitting unit group 21a and the display information M based on the illumination of the first light-emitting unit group 21a; a pedestrian in the nearby display area E2 can visually confirm the illumination of the corresponding second light-emitting unit group 21b and the display information M based on the illumination of the second light-emitting unit group 21b.

[0089] In the modified example, the light-emitting part group of the vehicle exterior display device 1, which can be visually confirmed from the opening 26a, is different depending on the relative position of the vehicle V and the pedestrian 100 located around the pedestrian crossing 200. Thus, the display information corresponding to the relative position of the vehicle and the pedestrian can be visually confirmed.

[0090] The case where the light-shielding member 26 in the modified example has multiple openings 26a corresponding to each light-emitting part 21 has been described, but it can also be replaced with a transmissive liquid crystal panel.

[0091] [Implementation Method 2]

[0092] Next, the vehicle exterior display device according to Embodiment 2 will be described. Figure 7 This is a diagram showing the structure of the display unit 20 according to Embodiment 2. Figure 8-1 This is a diagram showing the display area and display information in the case where the relative position of the vehicle and pedestrians around the crosswalk is far away, and there is an oncoming vehicle wanting to turn right, according to Embodiment 2. Figure 8-2 This is a diagram showing the display area and display information in the case where the relative position of the vehicle and pedestrians around the crosswalk is nearby and there are oncoming vehicles, according to Embodiment 2. Figure 8-3This diagram illustrates the display area and displayed information in the case where the relative position of the vehicle and pedestrians around the crosswalk is near each other, and there is an oncoming vehicle intending to turn right, as described in Embodiment 2. The exterior display device 1 in Embodiment 2 is a device that adds an oncoming vehicle display area E3 to the display area E of the exterior display device 1 in Embodiment 1. The basic structure of the exterior display device 1 in Embodiment 2 is the same as or substantially the same as that in Embodiment 1; therefore, the differences will be explained below.

[0093] The display area E of the display unit 20 includes a distant display area E1, a nearby display area E2, and an oncoming vehicle display area E3. The display area E is configured such that the distant display area E1 is sandwiched between the nearby display area E2 and the oncoming vehicle display area E3. The light-emitting unit 21 is composed of multiple light-emitting unit groups 21a, 21b, and 21c, each corresponding to a lens 22. The multiple light-emitting unit groups 21a, 21b, and 21c are a first light-emitting unit group 21a corresponding to the distant display area E1, a second light-emitting unit group 21b corresponding to the nearby display area E2, and a third light-emitting unit group 21c corresponding to the oncoming vehicle display area E3. The third light-emitting unit group 21c is composed of multiple third light-emitting units 213. The third light-emitting units 213 are arranged corresponding to each lens 22. In this embodiment, when adjacent to the first light-emitting unit 211, they are arranged at the other end of the two ends relative to each lens 22. The third light-emitting unit group 21c emits light corresponding to display information M related to the behavior of the vehicle V, which may be different from or the same as that of the first light-emitting unit group 21a and the second light-emitting unit group 21b. In the display area E3 for oncoming vehicles, a display is emitted that is different from the display related to the vehicle's behavior that can be visually confirmed by pedestrians 100 located around the crosswalk 200. Specifically, as... Figure 8-1As shown, when the relative position of the vehicle V and the pedestrian 100 around the crosswalk 200 is far away, and there is an oncoming vehicle 600 that wants to turn right onto road R′, which connects to the road R that the vehicle V is traveling on, the display area E1 displays "Stop," which is related to the future vehicle behavior and is directed towards the pedestrian 100 around the crosswalk 200. Additionally, in the nearby display area E2, for a vehicle 700 that is closer to the vehicle V than the pedestrian 100 around the crosswalk 200 and wants to merge from road R′ onto road R, the display area E2 displays "Pass," which is different from the display information M1 directed towards the pedestrian 100 around the crosswalk 200 and is related to the current vehicle behavior. On the other hand, when there is an oncoming vehicle 600 intending to turn right, although the display is intended for pedestrians 100 located around the crosswalk 200, the driver of the oncoming vehicle 600 might misinterpret it as a display directed towards that oncoming vehicle 600. Therefore, the oncoming vehicle display area E3 displays "Pass," a different display information M5 than the display related to vehicle behavior that pedestrians 100 around the crosswalk 200 can visually recognize. At this time, the first light-emitting unit group 21a emits light based on the display information M1 such as "Stop," the second light-emitting unit group 21b emits light based on the display information M2 such as "Pass," and the third light-emitting unit group 21c, corresponding to the oncoming vehicle display area E3, emits light based on the display information M5 such as "Pass." Additionally, as... Figure 8-2 As shown, when the relative position of the vehicle V and the pedestrian 100 around the crosswalk 200 is close and there is an oncoming vehicle 600 intending to turn right, the nearby display area E2 displays "Stopping," which is directed towards the pedestrian 100 around the crosswalk 200 and relates to the current vehicle behavior (M3). Additionally, the nearby display area E2 displays "Starting," which is directed towards a pedestrian 500 further away from the vehicle V than the pedestrian 100 around the crosswalk 200 and relates to future vehicle behavior (M4). Furthermore, the oncoming vehicle display area E3 displays "Pedestrian Crossing," which is different from the vehicle behavior information M3, which is visually identifiable by the pedestrian 100 around the crosswalk 200 (M3). At this time, the first light-emitting unit group 21a emits light based on the display information M4 such as "Starting," the second light-emitting unit group 21b emits light based on the display information M3 such as "Stopping," and the third light-emitting unit group 21c, corresponding to the oncoming vehicle display area E3, emits light based on the display information M5 such as "Pedestrian crossing." Thus, the oncoming vehicle 600 can notice the pedestrian 100 crossing the pedestrian crossing 200 and stop in front of the pedestrian crossing 200. Furthermore, as... Figure 8-3As shown, when the relative position of the vehicle V and the pedestrian 100 around the crosswalk 200 is considered to be near, and there is an oncoming vehicle 600 intending to turn right onto road R′, which connects to the road R to which the vehicle V is traveling, the display area E2 shows "Stopping," which is directed towards the pedestrian 100 around the crosswalk 200 and relates to the current vehicle's behavior (M3). Meanwhile, the distant display area E1 shows "Going Straight," which is directed towards pedestrians other than the pedestrian 100 around the crosswalk 200 and relates to future vehicle behavior (M4). On the other hand, when there is an oncoming vehicle 600 intending to turn right, although the display is for the pedestrian 100 around the crosswalk 200, the driver of the oncoming vehicle 600 might misunderstand it as a display directed towards that oncoming vehicle 600 and might remain idle until the vehicle V passes. Therefore, the oncoming vehicle display area E3 displays information M5 that is different from the vehicle behavior-related display that can be visually confirmed by pedestrians 100 around the crosswalk 200, such as "Right turn permitted while parked". At this time, the first light-emitting unit group 21a emits light based on the display information M4 of "Go straight", the second light-emitting unit group 21b emits light based on the display information M3 of "Parked", and the third light-emitting unit group 21c, corresponding to the oncoming vehicle display area E3, emits light based on the display information M5 of "Right turn permitted while parked". Thus, based on the positional relationship between the vehicle V and the oncoming vehicle, the display can be targeted at the other party, conveying useful information to them.

[0094] Next, the general operation of the external display device 1 will be explained. Figure 9 This is a flowchart illustrating an example of the control of the vehicle exterior display device according to Embodiment 2. The basic operation of the vehicle exterior display device 1 according to Embodiment 2 is the same as or substantially the same as that of the vehicle exterior display device 1 according to Embodiment 1, therefore, the differences will be explained below.

[0095] If the relative position of the vehicle V and the pedestrian 100 is determined to be a distant position (step S4: Yes), the display control unit 35 displays display information M1 related to the future behavior of the vehicle at the distant position in the distant display area E1, displays display information M2 related to the current behavior of the vehicle at the distant position in the nearby display area E2, and displays display information M5, which is different from the vehicle behavior related to the pedestrian 100 located around the crosswalk 200 at the distant position, in the oncoming vehicle display area E3 (step S9). For example, displaying display information M1 related to the future behavior of the vehicle, such as "stop," in the distant display area E1 allows the pedestrian 100, located at a distant position relative to the vehicle V, to determine whether the vehicle V has detected the pedestrian 100. In the nearby display area E2, display information M2, such as "Passing," is displayed to pedestrians and vehicles other than those around the pedestrians 100 surrounding the crosswalk 200, and is different from the information displayed to pedestrians 100 surrounding the crosswalk 200. Furthermore, if there is an oncoming vehicle 600 intending to turn right, although the display is intended for pedestrians 100 surrounding the crosswalk 200, the driver of the oncoming vehicle 600 might misinterpret it as a display directed towards that oncoming vehicle. Therefore, in the oncoming vehicle display area E3, display information M5, such as "Passing," is displayed, and is different from the display related to vehicle behavior that can be visually confirmed by pedestrians 100 surrounding the crosswalk 200. At this time, the first light-emitting unit group 21a emits light based on the display information M1 such as "stop", the second light-emitting unit group 21b emits light based on the display information M2 such as "pass", and the third light-emitting unit group 21c corresponding to the oncoming vehicle display area E3 emits light based on the display information M5 such as "pass" (see reference). Figure 8-1 ).

[0096] Next, the display control unit 35 calculates the positional relationship between the vehicle V, the pedestrian 100, and the crosswalk 200 (step S2). When it is determined that the vehicle V is approaching the crosswalk 200 (step S3: yes), it again determines whether the relative position of the vehicle V and the pedestrian 100 is a distant position (step S4). Thus, when the pedestrian 100 is still a distant position relative to the vehicle V, the display control unit 35 maintains the display state of display information M1 related to the future behavior of the vehicle at the distant position in the distant display area E1, maintains the display state of display information M2 related to the current behavior of the vehicle at the distant position in the nearby display area E2, and maintains the display state of display information M5, which is different from the display information related to vehicle behavior that can be visually confirmed by the pedestrian 100 located around the crosswalk 200 at the distant position, in the oncoming vehicle display area E3.

[0097] Furthermore, if it is determined that the relative position between the vehicle V and the pedestrian 100 is not far away, i.e., the relative position is nearby (step S4: No), the display control unit 35 causes the display information M3 related to the current behavior of the vehicle at the nearby position to be displayed in the nearby display area E2, the display information M4 related to the future behavior of the vehicle at the nearby position to be displayed in the far display area E1, and the display information M5, which is different from the display information related to vehicle behavior that can be visually confirmed by the pedestrian 100 located near the pedestrian crossing 200, to be displayed in the oncoming vehicle display area E3 (step S10). The display information M3 related to the current behavior of the vehicle, such as "parking", is displayed in the nearby display area E2 so that the pedestrian 100 located near the vehicle V can determine whether he or she can cross the pedestrian crossing 200. Since pedestrians 500, located far from vehicle V, will be concerned about the actions of the autonomous vehicle, a display information M4 related to future vehicle behavior, such as "starting," is displayed in a distant display area E1 that pedestrians 500 can visually confirm. Additionally, in the oncoming vehicle display area E3, a different display information M5 is displayed, unlike the display information related to vehicle behavior, such as "pedestrian crossing," which is visually confirmable by pedestrians 100 located around the crosswalk 200. At this time, the first light-emitting unit group 21a emits light based on the display information M4, such as "starting," the second light-emitting unit group 21b emits light based on the display information M3, such as "stopping," and the third light-emitting unit group 21c, corresponding to the oncoming vehicle display area E3, emits light based on the display information M5, such as "pedestrian crossing." (See reference) Figure 8-2 ).

[0098] Next, the display control unit 35 determines whether there is a pedestrian 100 around the pedestrian crossing 200 based on the pedestrian crossing location information X2 and the pedestrian location information X3 (step S11). Here, the display control unit 35 determines whether the pedestrian 100 has passed through the pedestrian crossing 200.

[0099] Next, when it is determined that a pedestrian 100 exists in the vicinity of the pedestrian crossing 200 (step S11: Yes), the display control unit 35 calculates the positional relationship between the vehicle V, the pedestrian 100, and the pedestrian crossing 200 (step S2), determines that the vehicle V is approaching the pedestrian crossing 200 (step S3: Yes), and determines that the relative position of the vehicle V and the pedestrian 100 is nearby (step S4: No). Therefore, when the pedestrian 100 is still nearby relative to the vehicle V, the display control unit 35 maintains the display state of display information M3 related to the current vehicle behavior in the nearby display area E2, maintains the display state of display information M4 related to the future vehicle behavior in the distant display area E1, and maintains the display state of display information M5, which is different from the display information related to vehicle behavior that can be visually confirmed by the pedestrian 100 located in the vicinity of the pedestrian crossing 200, in the oncoming vehicle display area E3.

[0100] Next, when it is determined that there are no pedestrians 100 around the pedestrian crossing 200 (step S11: no), the display control unit 35 ends the display of the display unit 20 (step S12).

[0101] The vehicle exterior display device 1 described above can display information to the intended recipient based on the positional relationship between the vehicle V and the oncoming vehicle, thus conveying useful information to the recipient.

[0102] Furthermore, the vehicle exterior display device 1 involved in the above-described embodiments 1, 2 and their variations is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims.

[0103] The cases described in Embodiments 1, 2, and their variations, where the vehicle V is capable of autonomous driving (semi-autonomous driving, fully autonomous driving), are not limited to this. The vehicle V may also be a manually drivable vehicle whose behavior is controlled by the driving operations of the driver of the vehicle V.

[0104] The description explains how the display unit 20 in Embodiments 1, 2 and its variations displays messages such as "parking" or "parking" as a display related to the vehicle's behavior, but it is not limited to this. In addition to messages, it may also display graphics, symbols, histograms or pictures.
