[0004] Patent Literature 1: JP 2014-144725 A SUMMARY OF THE INVENTION TECHNICAL PROBLEM

[0005] In the vehicle information display device described in Patent Literature 1, at the time when it is detected that the vehicle is in a certain state, a display pattern representing the vehicle state at that time is displayed outside the vehicle.

[0006] Since the actual situation inside and outside the vehicle changes from one time to another, a problem arises that even if information outside the vehicle is displayed only based on the vehicle state, information displayed outside the vehicle may not be accurately transmitted to a target person outside the vehicle in some situations inside and outside the vehicle.

[0007] The present invention solves the above problem, and an object of the present invention is to provide an irradiation apparatus and an irradiation method that can accurately inform a target person outside a vehicle of information displayed outside the vehicle. SOLUTION TO THE PROBLEM

The irradiation unit emits light and displays information outside a vehicle. The information acquisition unit acquires information regarding the situation inside and outside the vehicle. The determination unit determines whether or not the information regarding the situation outside the vehicle acquired by the information acquisition unit satisfies a display start condition. The control unit displays information outside the vehicle according to the display start condition determined by the determination unit as satisfying the information regarding the situation outside the vehicle, by controlling the one or more irradiation units.

[0009] In this configuration, after displaying the information outside the vehicle, the determination unit determines whether the information regarding the situation inside and outside the vehicle acquired by the information acquisition unit satisfies a display change condition or not.

[0010] When the determination unit determines that the information regarding the situation inside and outside the vehicle satisfies the display change condition, the control unit controls the one or more irradiation units and changes a display mode of each of the information displayed in parts of the outside the vehicle, comprising a first sensor directed externally to the vehicle, which is a sensor that detects an object in the surroundings of the vehicle; and a second sensor directed externally of the vehicle, which is a sensor that detects an object in the surroundings of the vehicle and is arranged at a different position than the first sensor directed externally of the vehicle, wherein the information acquisition unit receives detection information of the first vehicle-external sensor and the second vehicle-external sensor, and the determination unit determines a match between the detection information and the display start condition and / or a match between the detection information and the display change condition based on detection information of the first vehicle-external sensor and detection information of the second vehicle-external sensor. ADVANTAGEOUS EFFECTS OF THE INVENTION

[0011] According to the present invention, when the information regarding the situation inside and outside the vehicle satisfies the display change condition, the display mode of the information displayed outside the vehicle is changed, and therefore a target person outside the vehicle can be accurately informed of the information displayed outside the vehicle.

For example, by comparing the information regarding the situation inside and outside the vehicle acquired by the information acquisition unit 30 with a display start condition stored in the condition DB 31a, the determination unit 31 determines whether the information regarding the situation inside and outside the vehicle satisfies the condition information regarding the situation inside and outside the vehicle in the display start condition.

[0080] Note that a function of the determination unit 31 is implemented by executing a program read from the ROM 3a-2 by the processor 3a-1 of the integration determination ECU 3a.

[0081] When the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the condition information regarding the situation inside and outside the vehicle in the display start condition, the determination unit 31 outputs display information of the vehicle state corresponding to the display start condition to the control unit 32.

[0082] Note that when the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies each of a plurality of display start conditions stored in the condition DB 31a, the determination unit 31 outputs a plurality of pieces of display information corresponding to each of the display start conditions to the control unit 32.

[0083] After displaying the information outside the vehicle, the determination unit 31 determines whether or not the information regarding the situation inside and outside the vehicle acquired by the information acquisition unit 30 satisfies a display change condition.

[0084] The display change condition includes, in summary, display information of a vehicle state, condition information regarding the situation inside and outside the vehicle under which the display information should be changed, and information indicating a display mode of the above display information after the change. Examples of a condition under which the display information should be changed include a case where a pedestrian has come within a certain distance range near a vehicle door when an animation indicating a vehicle state where the door is about to be opened is displayed.

[0085] Examples of the display mode after the change include a mode where the blinking speed of a light pattern in the animation is increased (for example, double speed).

[0086] By comparing information regarding the situation inside and outside the vehicle acquired by the information acquisition unit 30 with a display change condition stored in the condition DB 31a, the determination unit 31 determines whether or not the information regarding the situation inside and outside the vehicle satisfies condition information regarding the situation inside and outside the vehicle in the display change condition. If the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the condition information regarding the situation inside and outside the vehicle in the display change condition, the determination unit 31 outputs information indicating a display mode after the change according to the display change condition to the control unit 32.

[0087] After changing the display mode of the information displayed outside the vehicle, the determination unit 31 determines whether the information regarding the situation inside and outside the vehicle acquired by the information acquisition unit 30 satisfies a display reset condition. The display reset condition includes, in summary, display information in which a display mode has been changed and condition information regarding the situation inside and outside the vehicle in which the display information should be reset to the display mode before the change.

[0088] Examples of a condition under which the display information about the display mode before the change should be reset include a case where a pedestrian moves away from a door of the vehicle by a certain distance or more after the display mode of an animation indicating a vehicle state in which the door is about to be opened is changed.

[0089] By comparing information regarding the situation inside and outside the vehicle acquired by the information acquisition unit 30 with a display reset condition stored in the condition DB 31a, the determination unit 31 determines whether or not the information regarding the situation inside and outside the vehicle satisfies the condition information regarding the situation inside and outside the vehicle in the display reset condition. If the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the condition information regarding the situation inside and outside the vehicle in the display reset condition, the determination unit 31 outputs the determination result to the control unit 32.

[0090] The determination unit 31 determines whether or not the information regarding the situation inside and outside the vehicle acquired by the information acquisition unit 30 satisfies a display termination condition.

[0091] The display termination condition is information that specifies condition information regarding the situation inside and outside the vehicle under which the display information should be terminated.

[0092] Examples of a condition under which the display information should be stopped include a case where there is no pedestrian who should be informed of a vehicle condition where a door of the vehicle is about to be opened in the vicinity of the vehicle.

[0093] By comparing information regarding the situation inside and outside the vehicle acquired by the information acquisition unit 30 with a display termination condition stored in the condition DB 31a, the determination unit 31 determines whether or not the information regarding the situation inside and outside the vehicle satisfies the condition information regarding the situation inside and outside the vehicle in the display termination condition. If the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the condition information regarding the situation inside and outside the vehicle in the display termination condition, the determination unit 31 outputs the determination result to the control unit 32.

[0094] The control unit 32 displays one or more pieces of display information input from the determination unit 31 and corresponding to one or more display start conditions outside the vehicle by controlling the lighting device 4a and the lighting device 4b. The display information is displayed outside the vehicle in the form of a light pattern, an animation, or an image.

[0095] A function of the control unit 32 is implemented by executing a program read from the ROM 3b-2 by the processor 3b-1 of the light control ECU 3b.

[0096] When the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the display change condition, the control unit 32 changes a display mode of the information displayed outside the vehicle by controlling the lighting device 4a and the lighting device 4b.

[0097] For example, the control unit 32 changes the display mode of the display information by controlling the lighting device 4a and the lighting device 4b based on the information indicating the display mode of the display information after the change, which is input from the determination unit 31. At this time, the control unit 32 stores information indicating the display mode before the change in the ROM 3b-2.

[0098] When the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the display reset condition, the control unit 32 resets the information whose display mode has been changed to the display mode before the change by controlling the lighting device 4a and the lighting device 4b.

[0099] For example, when the determination unit 31 inputs a determination result that the information regarding the situation inside and outside the vehicle satisfies the display reset condition to the control unit 32, the control unit 32 resets the display information to the display mode before the change by controlling the lighting device 4a and the lighting device 4b based on the information indicating the display mode before the change stored in the ROM 3b-2.

[0100] When the determination unit 31 inputs a determination result that the information regarding the situation inside and outside the vehicle satisfies the display termination condition to the control unit 32, the control unit 32 terminates the display of the display information by controlling the lighting device 4a and the lighting device 4b.

[0101] Next, the operation is described.

[0102] Fig. 3 is a flowchart illustrating an irradiation method according to the first embodiment.

[0103] First, the information acquisition unit 30 acquires information regarding the situation inside and outside the vehicle from the overall control ECU 2 (step ST1).

[0104] The information regarding the situation inside and outside the vehicle is detected by various sensors and vehicle devices contained in the in-vehicle device 1.

[0105] Examples of the information include vehicle speed information, steering angle information, accelerator pedal operation information, brake operation information, gear lever operation information, turn signal operation information, hazard warning operation information, windshield wiper operation information, light switch operation information, door opening / closing information, driver image information, passenger seat information, vehicle acceleration information, angular velocity information, position information, route information, image information around a vehicle, object detection information around a vehicle, illuminance information around a vehicle, door handle contact information, and seat belt fastening / unfastening information. The information acquisition unit 30 outputs information regarding the situation inside and outside the vehicle to the determination unit 31.

[0106] By comparing information regarding the situation inside and outside the vehicle acquired by the information acquiring unit 30 with a display start condition stored in the condition DB 31a, the determining unit 31 determines whether or not the information regarding the situation inside and outside the vehicle satisfies condition information regarding the situation inside and outside the vehicle in the display start condition (step ST2).

[0107] If the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the display start condition (step ST2; YES), the determination unit 31 outputs display information of a vehicle state corresponding to the display start condition to the control unit 32.

[0108] Meanwhile, if the determination unit 31 determines that the information regarding the situation inside and outside the vehicle does not satisfy the display start condition (step ST2; NO), the process of step ST1 is repeated.

[0109] It should be noted that the determination unit 31 may change a combination of conditions in the display start condition depending on the situation inside and outside the vehicle. For example, when the wiper sensor 1h detects that a wiper is operating (when it is raining), the determination unit 31 changes an illuminance condition effective for road surface display. When it is dry, for example, the illuminance condition is set to 50 lux or more. However, the illuminance condition is set to 20 lux when it is raining because irregular light reflection occurs. The determination unit 31 determines whether the situation inside and outside the vehicle satisfies the display start condition or not by comparing the changed condition with information regarding the situation inside and outside the vehicle.

[0110] For example, in a display start condition corresponding to a vehicle state where a door of the vehicle is about to be opened, conditions (1) to (14) are set as condition information regarding the situation inside and outside the vehicle. (1) The vehicle speed is zero. (2) The amount of operation of an accelerator pedal is zero. (3) A brake pedal is depressed. (4) A gear lever is in a parking position. (5) A warning light is illuminated. (6) A light switch is activated. (7) A vehicle door is closed. (8) A passenger is sitting in the vehicle. (9) A vehicle acceleration is zero. (10) The vehicle is in a position where the vehicle can stop. (11) There is a moving object (for example a pedestrian or a bicycle) in the vicinity of the vehicle. (12) The illuminance is effective for road surface display. (13) A passenger touches a door handle in the vehicle. (14) A seat belt of the occupant touching the door handle is unfastened. If the information regarding the situation inside and outside the vehicle satisfies all or some of the conditions (1) to (14), the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the above display start condition corresponding to a vehicle state in which a door of the vehicle is about to be opened.

[0111] For example, in a display start condition corresponding to a vehicle state where the vehicle is about to move forward or backward, conditions (1a) to (8a) are set as condition information regarding the situation inside and outside the vehicle. (1a) Vehicle speed is a speed at which the vehicle can stop suddenly. (2a) An accelerator pedal is pressed. (3a) A gear lever is in a drive position or a reverse position. (4a) A warning light is illuminated. (5a) A light switch is turned on. (6a) The vehicle is in a position where the vehicle can move forward or backward. (7a) There is a moving object (for example a pedestrian or a bicycle) in the vicinity of the vehicle. (8a) The illuminance is effective for road surface display.

[0112] When the information regarding the situation inside and outside the vehicle satisfies all or some of the conditions (1a) to (8a), the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the above display start condition corresponding to a vehicle state in which the vehicle is about to move forward or backward.

[0113] For example, in a display start condition corresponding to a vehicle state where the vehicle is about to turn left or right, conditions (1b) to (8b) are set as condition information regarding the situation inside and outside the vehicle. (1b) Vehicle speed is a speed at which the vehicle can stop suddenly. (2b) An accelerator pedal is pressed. (3b) A gear lever is located at a driving position. (4b) An indicator is activated. (5b) A light switch is turned on. (6b) The vehicle is in a position where the vehicle can turn left or right. (7b) There is a moving object (for example a pedestrian or a bicycle) in the vicinity of the vehicle. (8b) The illuminance is effective for road surface display.

[0114] When the information regarding the situation inside and outside the vehicle satisfies all or some of the conditions (1b) to (8b), the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the above display start condition corresponding to a vehicle state in which the vehicle is about to turn left or right.

[0115] For example, in a display start condition corresponding to a vehicle state where crossing in front of the vehicle is permitted, conditions (1c) to (9c) are set as condition information regarding the situation inside and outside the vehicle. (1c) The vehicle speed is zero or a speed at which the vehicle can stop suddenly. (2c) The amount of operation of an accelerator pedal is zero. (3c) A brake pedal is pressed. (4c) A gear lever is in a parking position. (5c) A light switch is turned on. (6c) A driver detects a pedestrian attempting to cross a road in front of the vehicle. (7c) The vehicle is in a position where a pedestrian can cross a road. (8c) There is a moving object (for example a pedestrian or a bicycle) attempting to cross a road in front of the vehicle. (9c) The illuminance is effective for road surface display.

[0116] When the information regarding the situation inside and outside the vehicle satisfies all or some of the conditions (1c) to (9c), the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the above display start condition corresponding to a vehicle state in which crossing in front of the vehicle is permitted.

[0117] For example, in a display start condition corresponding to a vehicle state in which vehicle entry guidance is provided, conditions (1d) to (5d) are set as condition information regarding the situation inside and outside the vehicle. (1d) The vehicle speed is zero or a speed at which the vehicle can stop suddenly. (2d) A light switch is turned on. (3d) The vehicle is located in a position where boarding guidance is possible. (4d) There is a target person for the initial tour. (5d) The illuminance is effective for road surface display.

[0118] When the information regarding the situation inside and outside the vehicle satisfies all or some of the conditions (1d) to (5d), the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the above display start condition corresponding to a vehicle state in which vehicle entry guidance is provided.

[0119] Note that an example of the display start condition has been described so far. However, the display start condition can be any condition other than the one described above, as long as it indicates a vehicle condition that a person outside the vehicle should be informed about.

[0120] The control unit 32 starts displaying the above display information outside the vehicle by controlling the lighting device 4a or the lighting device 4b based on display information input from the determination unit 31 (step ST3). Fig. 4A is a diagram illustrating display information 6a for notifying a person outside a vehicle 100 of a vehicle state in which the left rear door of the vehicle 100 is about to be opened, and illustrates the vehicle 100 as viewed from above. Fig. 4B is a diagram illustrating display information 6b for notifying a person outside the vehicle 100 of the vehicle state in which the left rear door of the vehicle 100 is about to be opened, and illustrates the vehicle 100 as viewed from the rear.

[0121] For example, the Fig. 4A illustrated display information 6a and / or the Fig. 4B is associated with condition information regarding the situation inside and outside the vehicle 100 in a display start condition corresponding to a vehicle state in which the left rear door of the vehicle 100 is about to be opened.

[0122] As in Fig. As illustrated in Figure 4A, the display information 6a is an animation of a fan-shaped irradiation pattern including three light patterns, and is displayed by the lamp 4a2 on a road surface on one side of the left rear door of the vehicle 100. This animation is an irradiation pattern to be illuminated sequentially from a light pattern at a position of the pivot point of the fan to a light pattern at an end position thereof. The fan shape of the animation corresponds to a range in which the left rear door moves when the left rear door is opened or closed.By visually recognizing the display information 6a displayed on a road surface on a side of the vehicle 100, a pedestrian who has moved to the side of the vehicle 100 from the rear thereof can recognize that the left rear door will be opened, and can further recognize an area in which the left rear door moves when the left rear door is opened or closed.

[0123] As in Fig. 4B, the display information 6b is an image with a text “DOOR OPEN” and is displayed by the lamp 4b2 on a rear window of the vehicle 100.

[0124] By visually recognizing the display information 6b displayed on the rear window of the vehicle 100, the pedestrian who has moved from the rear of the vehicle 100 can recognize that the left rear door is about to be opened. It is difficult for the driver to visually recognize the state of the external environment of the left rear door of the vehicle 100.

[0125] Therefore, in the first embodiment, by displaying the display information 6a or the display information 6b, the attention of a moving object outside the vehicle (for example, a pedestrian, a bicycle, or another vehicle) is drawn to the opening of the left rear door of the vehicle 100. In Fig. 4, the left rear door is exemplified, but the present invention can be applied to a left front door, a right front door, or a right rear door. The display content is an example, and therefore may vary depending on the shape of the vehicle or the like.

[0126] Fig. 5A is a diagram illustrating display information 7a-1 and 7a-2 for notifying a person outside the vehicle 100 of a vehicle state in which the vehicle 100 is about to move forward, and illustrates the vehicle 100 as viewed from above. Fig. 5B is a diagram illustrating display information 7b for notifying a person outside the vehicle 100 of the vehicle state in which the vehicle 100 is about to move forward, and illustrates the vehicle 100 as viewed from the rear.

[0127] For example, the Fig. 5A illustrated display information 7a-1 and 7a-2 and / or the Fig. 5B is associated with condition information regarding the situation inside and outside the vehicle 100 in a display start condition corresponding to the vehicle state in which the vehicle 100 is about to move forward.

[0128] As in Fig. As illustrated in Figure 5A, the display information 7a-1 and 7a-2 are each a stripe-shaped animation including four light patterns, and are displayed by the lamp 4a2 on a road surface at the left front and right front of the vehicle 100, respectively. In the animation, a sequence of operations is repeated in which a light pattern is sequentially illuminated from a light pattern closest to the vehicle 100 to a light pattern farthest from the vehicle 100, and then all light patterns are extinguished. The stripe shape of the animation corresponds to a moving direction of the vehicle 100.

[0129] By visually recognizing the display information 7a-1 and 7a-2 displayed on a road surface on one side of the vehicle 100, a pedestrian who has moved to a front of the vehicle 100 can recognize that the vehicle 100 is about to move forward. Note that the display content is an example, and therefore, it may change depending on the shape of the vehicle or the like.

[0130] As in Fig. 5B, the display information 7b is an image of an arrow mark indicating a traveling direction of the vehicle 100 and is displayed by the lamp 4b2 on a windshield of the vehicle 100.

[0131] By visually recognizing the display information 7b displayed on the windshield of the vehicle 100, a pedestrian who has moved to a front of the vehicle 100 can recognize that the vehicle 100 is about to move forward.

[0132] Fig. 6A is a diagram illustrating display information 8a for notifying a person outside the vehicle 100 of a vehicle state in which the vehicle 100 is about to move backward, and illustrates the vehicle 100 as viewed from above. Fig. 6B is a diagram illustrating display information 8b for notifying a person outside the vehicle 100 of a vehicle state in which the vehicle 100 is about to move backward, and illustrates the vehicle 100 as viewed from the rear.

[0133] For example, the Fig. 6A illustrated display information 8a and / or the Fig. 6B is associated with condition information regarding the situation inside and outside the vehicle 100 in a display start condition corresponding to a vehicle state in which the vehicle 100 is about to move backward.

[0134] As in Fig. As illustrated in Figure 6A, the display information 8a is an arrow-shaped animation including four light patterns, and is displayed by the lamp 4a2 on a road surface behind the vehicle 100. In the animation, a sequence of operations is repeated in which a light pattern is illuminated sequentially from a light pattern closest to the vehicle 100 to a light pattern farthest from the vehicle 100, and then all light patterns are extinguished. The arrow shape of the animation corresponds to a movement direction of the vehicle 100.

[0135] By visually recognizing the display information 8a displayed on a road surface behind the vehicle 100, a pedestrian who has moved to the rear of the vehicle 100 can recognize that the vehicle 100 is about to move backward.

[0136] As in Fig. 6B, the display information 8b is an image of an arrow mark indicating a traveling direction of the vehicle 100 and is displayed by the lamp 4b2 on a rear window of the vehicle 100.

[0137] By visually recognizing the display information 8b displayed on the rear window of the vehicle 100, a pedestrian who has moved to the rear of the vehicle 100 can recognize that the vehicle 100 is about to move backward. Note that the display content is an example, and therefore, it may change depending on the shape of the vehicle or the like.

[0138] Fig. Fig. 7 is a diagram illustrating display information 9 for notifying a person outside the vehicle 100 of a vehicle state in which the vehicle 100 is about to turn left, and illustrates the vehicle 100 as viewed from above. Fig. For example, the display information 9 illustrated in Fig. 7 is associated with condition information regarding the situation inside and outside the vehicle in a display start condition for notifying a person outside the vehicle 100 of a vehicle state in which the vehicle 100 is about to turn left.

[0139] The display information 9 is an image of a mark for drawing attention to the left turn of the vehicle 100 and is displayed by the lamp 4a2 on a road surface on the left rear side of the vehicle 100, as shown in Fig. 7. By visually recognizing the display information 9 displayed on a road surface at the left rear side of the vehicle 100, a cyclist about to move from the rear of the vehicle 100 to one side thereof can recognize that the vehicle 100 is about to turn left.

[0140] Fig. 8A is a diagram illustrating display information 10a for notifying a person outside the vehicle 100 of a vehicle state in which crossing in front of the vehicle 100 is permitted, and illustrates the vehicle 100 as viewed from above. Fig. 8B is a diagram illustrating display information 10b for notifying a person outside the vehicle 100 of a vehicle state in which crossing in front of the vehicle 100 is permitted, and illustrates the vehicle 100 as viewed from the front.

[0141] For example, the Fig. 8A illustrated display information 10a and / or the Fig. 8B is associated with condition information regarding the situation inside and outside the vehicle 100 in a display start condition corresponding to a vehicle state in which crossing in front of the vehicle is permitted.

[0142] As in Fig. As illustrated in FIG. 8A, the display information 10a is an image of an arrow mark in a direction of crossing a road in front of the vehicle 100, and is displayed by the lamp 4a2 on a road surface at the left front of the vehicle 100. By visually recognizing the display information 10a displayed on a road surface in front of the vehicle 100, a pedestrian who has moved to the left front of the vehicle 100 can recognize that crossing in front of the vehicle 100 is permitted.

[0143] As in Fig. As illustrated in FIG. 8B, the display information 10b is an image with the text "KEEP GOING" and is displayed by the lamp 4b2 on a windshield of the vehicle 100. By visually recognizing the display information 10b displayed on the windshield of the vehicle 100, a pedestrian who has moved to the left front of the vehicle 100 can recognize that crossing in front of the vehicle 100 is permitted. Note that the display content is an example, and therefore, it may change depending on the shape of the vehicle or the like.

[0144] Fig. 9A is a diagram illustrating display information 11a for notifying a person outside the vehicle 100 of a vehicle state in which entry guidance is provided, and illustrates the vehicle 100 as viewed from above. Fig. Fig. 9B is a diagram illustrating display information 11b for notifying a person outside the vehicle 100 of the vehicle state in which entry guidance is provided, and illustrates the vehicle 100 viewed from the front. For example, the Fig. 9A illustrated display information 11a and / or the Fig. 9B is associated with condition information regarding the situation inside and outside the vehicle 100 in a display start condition corresponding to a vehicle state in which entry guidance is provided.

[0145] As in Fig. As illustrated in Figure 9A, the display information 11a is a stripe-shaped animation including three light patterns, and is displayed by the lamp 4a2 on a road surface on a left side of the vehicle 100. In the animation, a series of operations is repeated in which a light pattern is sequentially illuminated from a light pattern farthest from the vehicle 100 to a light pattern closest to the vehicle 100, and then all the light patterns are extinguished. The stripe shape of the animation corresponds to an entry direction into the vehicle 100. By visually recognizing the display information 11a displayed on a road surface on a left side of the vehicle 100, a pedestrian who has moved to the left side of the vehicle 100 can recognize that the vehicle 100 is providing entry guidance.

[0146] As in Fig. 9B, the display information 11b is an image with a text “WELCOME” and is displayed by the lamp 4b2 on a windshield of the vehicle 100.

[0147] By visually recognizing the display information 11b displayed on the windshield of the vehicle 100, a pedestrian who has moved toward the front of the vehicle 100 can recognize that the vehicle 100 is providing boarding guidance. Note that the display content is an example, and therefore may vary depending on the shape of the vehicle or the like.

[0148] Now again referring to the description of Fig. 3. Even after displaying the display information outside the vehicle, the information acquisition unit 30 acquires information regarding the situation inside and outside the vehicle from the overall control ECU 2 (step ST4). The information regarding the situation inside and outside the vehicle acquired by the information acquisition unit 30 is output to the determination unit 31.

[0149] Next, the determination unit 31 determines whether or not the information regarding the situation inside and outside the vehicle acquired by the information acquisition unit 30 satisfies a display termination condition (step ST5).

[0150] Here, if the determination unit 31 determines that the information regarding the situation inside and outside the vehicle does not satisfy the display termination condition (step ST5; NO), the process proceeds to step ST6.

[0151] It should be noted that the display termination condition may be a situation where information regarding the situation inside and outside the vehicle does not meet the display start condition.

[0152] In step ST6, the determination unit 31 determines whether or not the information regarding the situation inside and outside the vehicle satisfies condition information regarding the situation inside and outside the vehicle in the display change condition by comparing information regarding the situation inside and outside the vehicle acquired by the information acquiring unit 30 with a display change condition stored in the condition DB 31a.

[0153] If the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the display change condition (step ST6; YES), the determination unit 31 outputs information indicating a display mode after the change according to the display change condition to the control unit 32.

[0154] Meanwhile, if the determination unit 31 determines that the information regarding the situation inside and outside the vehicle does not satisfy the display change condition (step ST6; NO), the process returns to step ST4 and the above-described process is repeated.

[0155] For example, in a display change condition corresponding to a vehicle state in which a door of the vehicle is about to be opened, conditions (1A) to (3A) are set as condition information regarding the situation inside and outside the vehicle. (1A) After displaying display information, a moving object (for example, a pedestrian, a bicycle, or another vehicle) has approached a door corresponding to the display information within a first distance (distance closer than that at the time the display information was started). (2A) After displaying display information, a moving object has approached a door corresponding to the display information within a second standoff distance (standoff distance closer than the first standoff distance). (3A) After displaying display information, a moving object has approached a door corresponding to the display information within a third distance (distance closer than the second distance).

[0156] When the information regarding the situation inside and outside the vehicle satisfies the conditions (1A) to (3A), the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the display change condition corresponding to a vehicle state in which a door of the vehicle is about to be opened.

[0157] For example, in a display change condition corresponding to a vehicle state where the vehicle is about to move forward or backward, conditions (1B) to (3B) are set as condition information regarding the situation inside and outside the vehicle. (1B) After displaying display information, a moving object (for example, a pedestrian, bicycle, or other vehicle) has approached within a first standoff distance in front of or behind the vehicle. (2B) After displaying display information, a moving object has approached within a second standoff distance in front of or behind the vehicle. (3B) After displaying display information, a moving object has approached within a third standoff distance in front of or behind the vehicle.

[0158] When the information regarding the situation inside and outside the vehicle satisfies the conditions (1B) to (3B), the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the display change condition corresponding to a vehicle state in which the vehicle is about to move forward or backward.

[0159] For example, in a display change condition corresponding to a vehicle state where the vehicle is about to turn left or right, conditions (1C) to (3C) are set as condition information regarding the situation inside and outside the vehicle. (1C) After displaying display information, a moving object (for example, a pedestrian, bicycle, or other vehicle) has approached within a first standoff distance to the right rear or left rear of the vehicle. (2C) After displaying display information, a moving object has approached within a second standoff distance to the right rear or left rear of the vehicle. (3C) After displaying display information, a moving object has approached within a third standoff distance to the right rear or left rear of the vehicle.

[0160] When the information regarding the situation inside and outside the vehicle satisfies the conditions (1C) to (3C), the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the display change condition corresponding to a vehicle state in which the vehicle is about to move forward or backward.

[0161] For example, in a display change condition corresponding to a vehicle state where crossing in front of the vehicle is permitted, conditions (1D) to (3D) are set as condition information regarding the situation inside and outside the vehicle. (1D) After displaying display information, a moving object (for example, a pedestrian, bicycle, or other vehicle) has approached within a first standoff distance in front of the vehicle. (2D) After displaying display information, a moving object has approached within a second standoff distance in front of the vehicle. (3D) After displaying display information, a moving object has approached within a third standoff distance in front of the vehicle.

[0162] When the information regarding the situation inside and outside the vehicle satisfies the conditions (1D) to (3D), the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the display change condition corresponding to a vehicle state in which the vehicle is about to move forward or backward.

[0163] For example, in a display change condition corresponding to a vehicle state in which vehicle entry guidance is provided, conditions (1E) to (3E) are set as condition information regarding the situation inside and outside the vehicle. (1E) After displaying display information, a target person for boarding guidance has approached within a first standoff distance of an boarding location. (2E) After displaying display information, a moving object has approached within a second standoff distance of an entry location of a target person for entry guidance. (3E) After displaying display information, a moving object has approached within a third standoff distance of an entry location of a target person for entry guidance.

[0164] When the information regarding the situation inside and outside the vehicle satisfies the conditions (1E) to (3E), the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the display change condition corresponding to a vehicle state in which the vehicle is about to move forward or backward.

[0165] Note that an example of the display change condition has been described so far. However, the display change condition can be a condition other than the one described above, as long as it specifies a situation where the display mode of the display information should be changed.

[0166] For example, the control unit 32 changes the display mode of the display information by controlling the lighting device 4a or the lighting device 4b based on the information indicating the display mode after the change input from the determination unit 31 according to the above display change condition.

[0167] When the display information is an animation, the control unit 32 changes the color and / or brightness and / or irradiation position and / or irradiation state change speed of the light pattern of the animation.

[0168] When the display information is an image, the control unit 32 changes the shape and / or color and / or brightness and / or size and / or display position and / or display timing and / or display time of the image.

[0169] Note that when the display mode of the display information is changed, the control unit 32 saves the display mode of the display information before the change. The saved display mode is used for a display reset process.

[0170] A sound may be output outside the vehicle according to the change of the display mode of the display information.

[0171] For example, the control unit instructs the overall control ECU 2 to output a sound from an out-of-vehicle speaker according to the change in the display mode of the display information. The overall control ECU 2 outputs a sound from the out-of-vehicle speaker according to an instruction from the control unit 32. The mode of the sound output from the out-of-vehicle speaker can be changed for each display mode after the change. Note that examples of the sound mode include volume, frequency characteristics, pitch, tempo, and the position of the out-of-vehicle speaker.

[0172] The display change condition includes, in summary, display information of a vehicle state, condition information regarding the situation inside and outside the vehicle in which the display information should be changed, and information indicating a display mode of the display information after the change.

[0173] For example, in a display change condition corresponding to a vehicle state in which the left rear door of the vehicle 100 is about to be opened, a display mode after the change for each of the conditions (1A) to (3A) is provided with the Fig. 4A illustrated display information 6a and the in Fig. 4B illustrated display information 6b.

[0174] The condition (1A) indicates a situation where a moving object has approached within a first distance to the left rear door corresponding to the display information 6a after displaying the display information 6a or the display information 6b.

[0175] For example, the condition (1A) is associated with a display mode in which the blinking speed of the light pattern of the display information 6a is faster than that before the change, and is associated with a display mode in which the text size of the display information 6b is larger than that before the change.

[0176] By controlling the lighting device 4a or the lighting device 4b based on the display mode after the change according to the condition (1A), the control unit 32 increases the flashing speed of the light pattern of the display information 6a or enlarges the text size of the display information 6b.

[0177] In the situation indicated by the condition (1A), a moving object such as a pedestrian is closer to the left rear door than at the time of display start of the display information 6a or the display information 6b.

[0178] Therefore, when the situation inside and outside the vehicle satisfies the condition (1A), the flashing speed of the light pattern of the display information 6a is increased or the text size of the display information 6b is increased.

[0179] As a result, the display information 6a or the display information 6b is highlighted. Therefore, visual recognition by a pedestrian or the like is easier, and the pedestrian or the like can be accurately informed that the left rear door is being opened.

[0180] Condition (2A) indicates a situation where a moving object has approached the left rear door within a second distance after displaying the display information 6a or the display information 6b. The second distance is a distance closer to the door than the first distance.

[0181] For example, the condition (2A) is associated with a display mode in which the blinking speed of the light pattern of the display information 6a is faster than that in the condition (1A) and the color of the light pattern is a pre-warning color such as yellow, and is associated with a display mode in which the text size of the display information 6b is larger than that in the condition (1A) and the character color is a pre-warning color.

[0182] By controlling the lighting device 4a or the lighting device 4b based on the display mode after the change according to the condition (2A), the control unit 32 increases the flashing speed of the light pattern of the display information 6a and changes the color of the light pattern to a pre-warning color, or enlarges the text size of the display information 6b and changes the character color to a pre-warning color.

[0183] In the situation specified by condition (2A), a moving object such as a pedestrian is closer to the left rear door than in the situation specified by condition (1A).

[0184] Therefore, when the situation inside and outside the vehicle satisfies the condition (2A), the flashing speed of the light pattern of the display information 6a is increased and the color of the light pattern is changed to a pre-warning color, or the text size of the display information 6b is increased and the character color is changed to a pre-warning color.

[0185] As a result, the display information 6a or the display information 6b is further emphasized. Therefore, visual recognition by a pedestrian or the like is easier, and the pedestrian or the like can be accurately informed that the left rear door is being opened.

[0186] Condition (3A) indicates a situation where a moving object has approached the left rear door within a third distance after displaying the display information 6a or the display information 6b. The third distance is a distance closer to the door than the second distance.

[0187] For example, the condition (3A) is associated with a display mode in which the flashing speed of the light pattern of the display information 6a is faster than that in the condition (2A) and the color of the light pattern is a warning color such as red, and is associated with a display mode in which the text size of the display information 6b is larger than that in the condition (2A) and the character color is a warning color.

[0188] By controlling the lighting device 4a or the lighting device 4b based on the display mode after the change according to the condition (3A), the control unit 32 further increases the flashing speed of the light pattern of the display information 6a and changes the color of the light pattern to a warning color, or further enlarges the text size of the display information 6b and changes the character color to a warning color.

[0189] In the situation specified by condition (3A), a moving object such as a pedestrian is closer to the left rear door than in the situation specified by condition (2A).

[0190] Therefore, when the situation inside and outside the vehicle satisfies the condition (3A), the flashing speed of the light pattern of the display information 6a is increased and the color of the light pattern is changed to a warning color, or the text size of the display information 6b is increased and the character color is changed to a warning color.

[0191] As a result, the display information 6a or the display information 6b is further emphasized. Therefore, visual recognition by a pedestrian or the like is easier, and the pedestrian or the like can be accurately informed that the left rear door is being opened.

[0192] So far, the case where the display mode of the display information 6a and 6b is changed for notifying a person outside a vehicle 100 of the vehicle state in which the left rear door of the vehicle 100 is about to be opened has been described.However, the control unit 32 may also similarly change the display mode in the display information 7a-1, 7a-2, 7b, 8a, and 8b for notifying a person outside the vehicle of a vehicle state in which the vehicle is about to move forward or backward, the display information 9 for notifying a person outside the vehicle of a vehicle state in which the vehicle is about to turn left or right, the display information 10a and 10b for notifying a person outside the vehicle of a vehicle state in which crossing in front of the vehicle is permitted, and the display information 11a and 11b for notifying a person outside the vehicle of a vehicle state in which entry guidance into the vehicle is provided.As a result, a target person outside the vehicle can be accurately informed of the vehicle status indicated by the display information.

[0193] So far, the display change condition according to a distance (first to third distance distances) between a moving object (a pedestrian, a bicycle, or another vehicle) outside the vehicle and the vehicle has been described. However, in the first embodiment, a display change condition may be set according to the position of the moving object around the vehicle, a moving direction, a distance between the vehicle and the moving object, and a moving speed.

[0194] The determination unit 31 determines, for example, whether the position of the moving object in the surroundings of the vehicle and / or a moving direction and / or a distance between the vehicle and the moving object and / or a moving speed detected by the information detection unit 30 satisfy the above display change condition.

[0195] When the determination unit 31 determines that the position of the moving object and / or a moving direction and / or a distance between the vehicle and the moving object and / or a moving speed satisfy the above display change condition, the control unit 32 changes the display mode of one or more pieces of display information by controlling the lighting device 4a or the lighting device 4b.

[0196] Even with such a configuration, the display mode of the display information is changed depending on the situation inside and outside the vehicle, and a target person outside the vehicle can be accurately informed of the display information.

[0197] Even after changing the display mode of the display information, the information acquisition unit 30 acquires information regarding the situation inside and outside the vehicle from the overall control ECU 2 (step ST8). The information regarding the situation inside and outside the vehicle acquired by the information acquisition unit 30 is output to the determination unit 31.

[0198] In step ST9, the determination unit 31 determines whether or not the information regarding the situation inside and outside the vehicle satisfies condition information regarding the situation inside and outside the vehicle in the display reset condition by comparing information regarding the situation inside and outside the vehicle acquired by the information acquiring unit 30 with a display reset condition stored in the condition DB 31a.

[0199] For example, if an in-vehicle sensor (e.g., the door handle sensor 1t) fails to respond while displaying information (animation) about a vehicle state in which a vehicle door is about to be opened, the animation display mode is changed (the intensity of the display is reduced). When the in-vehicle sensor responds again and resets the display, the animation flashes (the display is reset by sustained attention gain).

[0200] If the determination unit 31 determines that the information regarding the situation inside and outside the vehicle does not satisfy the display reset condition (step ST9; NO), the process returns to step ST8. As a result, the above-described process is repeated.

[0201] Meanwhile, if the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the display reset condition (step ST9; YES), the determination unit 31 outputs information indicating the determination result to the control unit 32. If the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the display reset condition, the control unit 32 resets the display mode of the display information to the original mode by controlling the lighting device 4a or the lighting device 4b (step ST10). As a result, the display information outside the vehicle is displayed in the display mode before the change. Thereafter, the process returns to step ST4, and the above-described sequence of processes is repeated until the situation inside and outside the vehicle satisfies a display termination condition.

[0202] Note that, for example, if the animation blinking occurs once every 2 seconds in step ST3 and the animation blinking occurs once per second in step ST7, the animation blinking operation is performed twice per second after the process of step ST10 is completed and before the process returns to the display of step ST3. That is, a process for changing a display mode from those in steps ST3 and ST7 may be added. This blinking operation is an example and can be freely specified.

[0203] For example, as a display reset condition of the display information 6a, a situation (a) where a moving object moves away from the left rear door and goes outside a first distance, a situation (b) where a moving object moves away from the left rear door and goes outside a second distance, and a situation (c) where a moving object moves away from the left rear door and goes outside a third distance are set. When the determination unit 31 determines that the situation inside and outside the vehicle satisfies condition (c) as a display reset condition, the control unit 32 resets the display mode of the display information 6a or the display information 6b to the state before the change based on condition (3A) by controlling the lighting device 4a or the lighting device 4b.As a result, the flashing speed of the light pattern of the display information 6a returns to that before the change, and the color of the light pattern also returns from the warning color to the pre-warning color. The text size of the display information 6b returns to that before the change, and the character color also returns from the warning color to the pre-warning color.

[0204] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies condition (b) as a display reset condition, the control unit 32 returns the display mode of the display information 6a or the display information 6b to the state before the change based on condition (2A) by controlling the lighting device 4a or the lighting device 4b. As a result, the flashing speed of the light pattern of the display information 6a returns to that before the change, and the color of the light pattern also returns from the pre-warning color to the color at the time the display information 6a started. The text size of the display information 6b returns to that before the change, and the character color also returns from the pre-warning color to the color at the time the display information 6b started.

[0205] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies condition (a) as a display reset condition, the control unit 32 returns the display mode of the display information 6a or the display information 6b to the state before the change based on condition (1A) by controlling the lighting device 4a or the lighting device 4b. As a result, the flashing speed of the light pattern of the display information 6a returns to that at the time the display information 6a was started. The text size of the display information 6b returns to that at the time the display information 6b was started.

[0206] When the process of step ST10 is completed, the process returns to step ST4, and the above-described process is repeated. In the above-described process, if the determination unit 31 determines that the information regarding the situation inside and outside the vehicle satisfies the above display termination condition (step ST5; YES), the control unit 32 terminates the display of the display information by controlling the lighting device 4a or the lighting device 4b (step ST11). As a result, a Fig. 3 illustrated sequence of processes

[0207] When there are multiple detection areas around the vehicle by multiple out-of-vehicle sensors 1r arranged in the vehicle, display information may be displayed depending on a detection situation of a moving object in these detection areas, and a display mode may be changed.

[0208] Fig. 10A is a diagram illustrating detection ranges of the plurality of vehicle-external sensors 1r, and illustrates the vehicle 100 as viewed from above. Fig. 10B is a diagram showing an attention-gathering detection area in a vehicle state where the left rear door of the vehicle 100 is about to be opened, among the detection areas of Fig. 10A illustrates and illustrates the vehicle 100 viewed from above.

[0209] As in Fig. 10A, the detection areas A to D are located in front of the vehicle 100, and the detection areas a to d are located behind the vehicle 100.

[0210] Examples of the off-vehicle sensor 1r include a corner sensor disposed in the vehicle 100. However, the off-vehicle sensor 1r may be a LiDAR sensor, and the detection areas A to D and a to d may be achieved by the off-vehicle camera 1q instead of the off-vehicle sensor 1r.

[0211] A situation in which a moving object (a pedestrian or a bicycle) has been detected in the detection area A can be set as a display start condition of the display information 6a. A situation in which the moving object has been detected in the detection area a can be set as a display change condition of the display information 6a. A situation in which the moving object has not been detected in the detection area a for a certain period of time can be set as a display reset condition of the display information 6a.

[0212] When a pedestrian is detected in the detection area A, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start condition. When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start condition, the control unit 32 starts displaying the display information 6a, as shown in Fig. 10B illustrates.

[0213] If a pedestrian is detected in the detection area a after displaying the display information 6a, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display change condition. If the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display change condition, the control unit 32 changes the display mode of the display information 6a.

[0214] If a pedestrian is not detected in the detection area a for a certain period of time after the display mode of the display information 6a is changed, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display reset condition. If the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display reset condition, the control unit 32 resets the display mode of the display information 6a to the mode before the change.

[0215] A situation where the moving object has been detected in the detection area a can be set as a display start condition of the display information 6a, and a situation where the moving object has not been detected in the detection area a for a certain time can be set as a display end condition of the display information 6a.

[0216] When a pedestrian is detected in the detection area a, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start condition. When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start condition, the control unit 32 starts displaying the display information 6a, as shown in Fig. 10B illustrates.

[0217] If a pedestrian has not been detected in the detection area a for a certain period of time, the determination unit 31 determines that the situation inside and outside the vehicle meets the display termination condition. If the determination unit 31 determines that the situation inside and outside the vehicle meets the display termination condition, the control unit 32 stops displaying the display information 6a.

[0218] A situation where the moving object has been detected in the detection area a can be set as a display start condition of the display information 6a, and a situation where the moving object has been detected in the detection area A can be set as a display end condition of the display information 6a.

[0219] When a pedestrian is detected in the detection area a, the determination unit 31 determines that the situation inside and outside the vehicle meets the display start condition. When the determination unit 31 determines that the situation inside and outside the vehicle meets the display start condition, the control unit 32 starts displaying the display information 6a.

[0220] When the pedestrian is moving and is detected in the detection area A, the determination unit 31 determines that the situation inside and outside the vehicle meets the display termination condition. When the determination unit 31 determines that the situation inside and outside the vehicle meets the display termination condition, the control unit 32 stops displaying the display information 6a.

[0221] Note that the display information 6a for notifying a person outside the vehicle of a vehicle state in which the left rear door is about to be opened has been described so far. However, for the display information 6b, the start of display, change of a display mode, reset of the display mode, and termination of display can be performed similarly.

[0222] Likewise, for the display information 7a-1, 7a-2, 7b, 8a and 8b for notifying a person outside the vehicle of a vehicle state in which the vehicle is about to move forward or backward, the display information 9 for notifying a person outside the vehicle of a vehicle state in which the vehicle is about to turn left or right, the display information 10a and 10b for notifying a person outside the vehicle of a vehicle state in which crossing in front of the vehicle is permitted, and the display information 11a and 11b for notifying a person outside the vehicle of a vehicle state in which entry guidance into the vehicle is provided, the start of displaying, the change of a display mode, the resetting of the display mode, and the termination of displaying can be performed similarly.

[0223] A situation where the illuminance around the vehicle exceeds a threshold may be set as a display change condition of the display information, and a situation where the illuminance around the vehicle becomes equal to or lower than the above threshold and a certain time has elapsed may be set as a display reset condition of the display information.

[0224] For example, if the illuminance sensor 1s detects that the illuminance around the vehicle has exceeded a threshold after displaying the display information, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display change condition. If the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display change condition, the control unit 32 changes the display mode of the display information.

[0225] In the display mode after the change, the display information can be visually recognized even at an illuminance exceeding the threshold. For example, if the display information is an animation, the color or brightness of the light pattern is changed in such a way that the animation can be visually recognized even at an illuminance exceeding the threshold. If the display information is an image, the shape, color, brightness, and size of the image are changed in such a way that the image can be visually recognized even at an illuminance exceeding the threshold.

[0226] When the illuminance sensor 1s detects that the illuminance around the vehicle has become equal to or lower than the threshold and a certain time has passed after the change of the display mode of the display information, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display reset condition.

[0227] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display reset condition, the control unit 32 resets the display mode of the display information to the mode before the change.

[0228] Multiple pieces of display information can be displayed at multiple locations outside the vehicle depending on the situation inside and outside the vehicle.

[0229] By adding display information of a new vehicle state depending on the situation inside and outside the vehicle, in addition to the display information for notifying a vehicle state such as a door being opened, attention is more accurately captured. As a result, attention can be captured appropriately even when, for example, there are one or two pedestrians present. Fig. 11 is a diagram illustrating several pieces of display information for notifying a person outside the vehicle of a vehicle state in which the left rear door is about to be opened, and illustrates the vehicle 100 viewed from above. In Fig. 11, the detection areas A to D are located in front of the vehicle 100, and the detection areas a to d are located behind the vehicle 100, as in Fig. 10A.

[0230] As a display start condition (a) of the display information 6a for notifying a person outside the vehicle of a vehicle state in which the left rear door is about to be opened, for example, a situation in which a moving object (a pedestrian, a bicycle, or another vehicle) has been detected in the detection area a is set.

[0231] As a display start condition (b) of the display information 9b for drawing attention from a moving object approaching the vehicle 100 from the right front side thereof to a moving object moving from the rear of the vehicle 100 to the left front side thereof, a situation is set where a moving object has been detected in the detection area D and a moving object has been detected in the detection area a or the detection area A.

[0232] As a display start condition (c) of the display information 9a for drawing attention of a moving object moving from the rear of the vehicle 100 to the left front side to a moving object approaching the vehicle 100 from the right front side thereof, a situation is set where a moving object has been detected in the detection area a or detection area A and a moving object has been detected in the detection area D.

[0233] When a pedestrian 200a is detected in the detection area a, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start condition (a). When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start condition (a), the control unit 32 starts displaying the display information 6a, as shown in Fig. 11 illustrates.

[0234] Meanwhile, if the pedestrian 200a is detected in the detection area a or the detection area A and a pedestrian 200b is further detected in the detection area D, the pedestrian 200a and the pedestrian 200b may collide with each other when they meet.

[0235] Therefore, when the pedestrian 200a is detected in the detection area a or detection area A and the pedestrian 200b is detected in the detection area D, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start conditions (b) and (c). When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start conditions (b) and (c), the control unit 32 starts displaying the display information 9a and the display information 9b, as shown in Fig. 11 illustrates.

[0236] As a result, the attention of the pedestrian 200a is drawn to the pedestrian 200b by the display information 9a, and the attention of the pedestrian 200b is drawn to the pedestrian 200a by the display information 9b.

[0237] The display modes of the multiple display information pieces can be changed depending on a movement situation between moving objects around the vehicle.

[0238] As a display change condition of the display information 9a, for example, a situation is set in which an approach of a moving object within a certain distance from the vehicle 100 in the detection area D has been detected.

[0239] As a display change condition of the display information 9b, a situation is set in which a moving object has been detected in the detection area A after the detection of a moving object in the detection area a.

[0240] If, after detecting the approach of the pedestrian 200b within a certain distance from the vehicle 100 in the detection area D and after detecting the pedestrian 200a in the detection area a, the pedestrian 200a and the pedestrian 200b are expected to approach each other.

[0241] When the determination unit 31 determines that the situation inside and outside the vehicle meets the display change condition, the control unit 32 changes the display modes of the display information 9a and the display information 9b to more prominent modes. As a result, the attention of the pedestrian 200a can be accurately drawn to the pedestrian 200b, and the attention of the pedestrian 200b can be accurately drawn to the pedestrian 200a.

[0242] Fig. 12A is a diagram illustrating display information 10a for notifying a person outside the vehicle 100 of a vehicle state in which crossing in front of the vehicle 100 is permitted, and illustrates the vehicle 100 as viewed from above. Fig. 12B is a diagram illustrating display information 9d and 9c for attracting the attention of both a pedestrian 200c and a newly approaching vehicle 300, and illustrates the vehicle 100 as viewed from above.

[0243] In the Fig. 12A and Fig. 12B, the detection areas A to D are located in front of the vehicle 100, and the detection areas a to d are located behind the vehicle 100, as in Fig. 10A.

[0244] As a display start condition (a1) of the display information 10a for notifying a person outside the vehicle of a vehicle state in which crossing in front of the vehicle is permitted, for example, a situation in which a moving object (a pedestrian, a bicycle, or another vehicle) has been detected in the detection area A is set.

[0245] As a display start condition (b1) of the display information 9c for drawing attention of a moving object approaching from the rear of the vehicle 100 to the right front thereof to a moving object moving from the left side of the vehicle 100 to the right front thereof, a situation is set where a moving object has been detected in the detection area d and a moving object has been detected in the detection area C.

[0246] As a display start condition (c1) of the display information 9d for drawing attention of a moving object approaching from the left side of the vehicle 100 to the right front thereof to a moving object moving from the rear of the vehicle 100 to the right front thereof, a situation is set where a moving object has been detected in the detection area C and a moving object has been detected in the detection area d.

[0247] When the pedestrian 200c is detected in the detection area A, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start condition (a1).

[0248] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start condition (a1), the control unit 32 starts displaying the display information 10a as shown in Fig. 12A illustrates.

[0249] Meanwhile, if the pedestrian 200c is detected in the detection area C and the vehicle 300 is further detected in the detection area d, the pedestrian 200c and the vehicle 300 may collide with each other.

[0250] Therefore, when the pedestrian 200c is detected in the detection area C and the vehicle 300 is detected in the detection area d, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start conditions (b1) and (c1).

[0251] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start conditions (b1) and (c1), the control unit 32 starts displaying the display information 9c and the display information 9d as shown in Fig. 11. As a result, the attention of a driver of the vehicle 300 is drawn to the pedestrian 200c by the display information 9c, and the attention of the pedestrian 200c is drawn to the vehicle 300 by the display information 9d.

[0252] As a display change condition of the display information 9d, for example, a situation is set in which an approach of a moving object within a certain distance from the vehicle 100 has been detected in the detection range d.

[0253] When it is detected that the vehicle 300 has approached within a certain distance from the vehicle 100 in the detection area d, the pedestrian 200c and the vehicle 300 are expected to approach each other.

[0254] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the above display change condition, the control unit 32 changes the display mode of the display information 9d to a more prominent mode.

[0255] As a result, the attention of the pedestrian 200c can be more accurately directed to the approach of the vehicle 300.

[0256] When there are multiple detection areas around the vehicle, the irradiation device 3 according to the first embodiment can change the display position of display information depending on a detection situation of a moving object in these detection areas. Fig. 13A is a diagram illustrating an attention-gathering detection area in a vehicle state where the vehicle 100 is about to move backward among a plurality of detection areas, and illustrates the vehicle 100 as viewed from above. Fig. 13B is a diagram illustrating how the display position of display information is changed depending on a movement of a pedestrian behind the vehicle, and illustrates the vehicle 100 as viewed from the rear.

[0257] In the Fig. 13A and Fig. 13B, the detection areas A to D are located in front of the vehicle 100, and the detection areas a to d are located behind the vehicle 100, as in Fig. 10A.

[0258] The Fig. 1 illustrates the lamp 4a2 showing display information on a road surface corresponding to each of the Fig. 13A and Fig. 13B illustrates detection areas a to d behind the vehicle 100.

[0259] The Fig. The lamp 4b2 illustrated in Figure 1 displays display information in each of the areas aa, bb, cc and dd of the rear window of the vehicle 100.

[0260] It should be noted that the rear window area aa corresponds to the detection area a, the rear window area bb corresponds to the detection area b, the rear window area cc corresponds to the detection area c and the rear window area dd corresponds to the detection area d.

[0261] As a display start condition of the display information for notifying a person outside the vehicle 100 of a vehicle state in which the vehicle 100 is about to move backward, for example, a situation in which a moving object (a pedestrian, a bicycle, or another vehicle) has been detected in the detection areas a to d is set.

[0262] When a pedestrian 200d is detected in the detection area a, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the above display start condition.

[0263] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start condition, the control unit 32 specifies the detection area b adjacent to the detection area a in which the pedestrian 200d was detected (adjacent detection area in the moving direction of the pedestrian 200d).

[0264] The control unit 32 starts displaying the display information in an area on a road surface corresponding to the specified detection area b by controlling the lighting device 4a as shown in Fig. 13B illustrates.

[0265] The control unit 32 can start displaying the display information in the area bb of the rear window corresponding to the detection area b by controlling the lighting device 4b, as shown in Fig. 13B illustrates.

[0266] As a display change condition of the display information, for example, a situation is set where a moving object was detected in a detection area adjacent to the detection area in which a moving object was detected at the time of displaying the display information, among the detection areas a to d.

[0267] When the pedestrian 200d is detected in the detection area b subsequent to the detection area a, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display change condition.

[0268] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display change condition, the control unit 32 specifies the detection area c adjacent to the detection area b in which the pedestrian 200d was detected (adjacent detection area in the moving direction of the pedestrian 200d).

[0269] The control unit 32 changes the display position of the display information to an area on a road surface corresponding to the specified detection area c by controlling the lighting device 4a.

[0270] The control unit 32 can change the display position of the display information to the area cc on the rear window according to the detection area c by controlling the lighting device 4b.

[0271] As described above, the display position of the display information is changed depending on a detection situation of a moving object in the multiple detection areas.

[0272] As a display reset condition of the display information, a situation may be set where a moving object is detected again in a detection area in which a moving object was detected among the detection areas a to d.

[0273] For example, when the pedestrian 200d is detected again in the detection area b subsequent to the detection area c, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display reset condition.

[0274] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display reset condition, the control unit 32 specifies the detection area a adjacent to the detection area b in which the pedestrian 200d was detected (adjacent detection area in the moving direction of the pedestrian 200d).

[0275] The control unit 32 changes the display position of the display information to an area on a road surface corresponding to the specified detection area a by controlling the lighting device 4a.

[0276] The control unit 32 can change the display position of the display information to the area aa on the rear window according to the detection area a by controlling the lighting device 4b.

[0277] As described above, the display position of the display information is reset to the position before the change depending on the detection situation of a moving object in the multiple detection areas. As a result, attention can be appropriately aroused depending on the detection situation of a moving object.

[0278] The irradiation device 3 according to the first embodiment can change the display position of the display information depending on the moving speed of a moving object around the vehicle, its moving direction, and a distance between the moving object and the vehicle. Fig. 14A is a diagram illustrating an example of display information for a pedestrian 200e near the vehicle 100, and illustrates the vehicle 100 as viewed from above. Fig. 14B is a diagram illustrating an example of display information for a bicycle remote from the vehicle 100, and illustrates the vehicle 100 as viewed from above. Fig. 14A and Fig. 14B, the detection areas A to D are located in front of the vehicle 100, and the detection areas a to d are located behind the vehicle 100, as in Fig. 10A.

[0279] As a display start condition of the display information 9 for drawing attention to the left rear door of the vehicle 100, for example, a situation is set in which the display information 6a is displayed corresponding to a vehicle state in which the left rear door is about to be opened and a moving object around the vehicle has been detected in the detection range a.

[0280] As a display change condition of the display information 9, a situation is set where the vehicle 100 is present in the moving direction of a moving object in the detection range a and is present in the surroundings of the vehicle, the moving speed of the moving object is one of a plurality of speed ranges, and a distance between the moving object and the vehicle 100 is one of a plurality of separation distances.

[0281] When a pedestrian 200e or a bicycle 200f is detected in the detection area a after displaying the display information 6a, the determination unit 31 determines that the situation inside and outside the vehicle meets the display start condition. At this time, the determination unit 31 outputs the moving direction of the pedestrian 200e or the bicycle 200f, its moving speed, and a distance between the vehicle 100 and the pedestrian 200e or the bicycle 200f, which are acquired by the information acquisition unit 30, to the control unit 32, in addition to the display information 9 corresponding to the display start condition.

[0282] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start condition, the control unit 32 specifies the position of the pedestrian 200e or the bicycle 200f based on the moving direction of the pedestrian 200e or the bicycle 200f, its moving speed, and a distance between the vehicle 100 and the pedestrian 200e or the bicycle 200f.

[0283] The control unit 32 starts displaying the display information 9 near the specified position of the pedestrian 200e or the bicycle 200f by controlling the lighting device 4a.

[0284] After displaying the display information 9, when the vehicle 100 is present in the moving direction of the pedestrian 200e, the moving speed of the pedestrian 200e is one of a plurality of speed ranges, and a distance between the pedestrian 200e and the vehicle 100 is one of a plurality of distance distances, the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display change condition. At this time, the determination unit 31 outputs the moving direction of the pedestrian 200e, its moving speed, and a distance between the vehicle 100 and the pedestrian 200e, which are acquired by the information acquisition unit 30, to the control unit 32.

[0285] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display change condition, the control unit 32 specifies the position of the pedestrian 200e based on the moving direction of the pedestrian 200e, its moving speed, and a distance between the vehicle 100 and the pedestrian 200e.

[0286] The control unit 32 changes the display position of the display information 9 near the specified position of the pedestrian 200e by controlling the lighting device 4a, as shown in Fig. 14A illustrates.

[0287] As described above, by displaying the display information 9 depending on the moving speed of the pedestrian 200e, the moving direction thereof, and a distance between the vehicle 100 and the pedestrian 200e, the attention of the pedestrian 200e can be accurately directed to the opening of the left rear door of the vehicle 100.

[0288] After displaying the display information 9, when the vehicle 100 is present in the moving direction of the bicycle 200f, the moving speed of the bicycle 200f is one of a plurality of speed ranges, and a distance between the bicycle 200f and the vehicle 100 is one of a plurality of distance distances, the determination unit 31 determines that the situation inside and outside the vehicle meets the display change condition. At this time, the determination unit 31 outputs the moving direction of the bicycle 200f, its moving speed, and a distance between the vehicle 100 and the bicycle 200f, which are acquired by the information acquisition unit 30, to the control unit 32.

[0289] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display change condition, the control unit 32 specifies the position of the bicycle 200f based on the moving direction of the bicycle 200f, its moving speed, and a distance between the vehicle 100 and the bicycle 200f.

[0290] The control unit 32 changes the display position of the display information 9 near the specified position of the bicycle 200f by controlling the lighting device 4a, as shown in Fig. 14B illustrates.

[0291] As described above, by displaying the display information 9 depending on the moving speed of the bicycle 200f, its moving direction and a distance between the vehicle 100 and the bicycle 200f, the attention of a rider of the bicycle 200f can be accurately directed to the opening of the left rear door of the vehicle 100.

[0292] The case of drawing attention to the vehicle state where a door of the vehicle 100 is about to be opened by changing the display position of the display information depending on the moving speed of a moving object around the vehicle, its moving direction, and a distance between the moving object and the vehicle has been described. However, no limitation is intended.

[0293] Similarly, by changing the display position of the display information, attention can be drawn to a vehicle state in which the vehicle is about to move forward or backward, a vehicle state in which the vehicle is about to turn left or right, a vehicle state in which crossing in front of the vehicle is permitted, a vehicle state in which boarding guidance into the vehicle is provided, and a vehicle state in which the attention of a pedestrian around the vehicle is attracted.

[0294] Fig. 15 is a diagram illustrating how the display position of display information is changed depending on a distance from the vehicle 100 to a target person outside the vehicle. Fig. The lamp 4b2 illustrated in Figure 1 may be capable of displaying information in each of the plurality of display areas A1 to A4 of the rear window of the vehicle 100, as shown on the right side of Fig. 15 illustrates.

[0295] As on the right side of Fig. 15, the display area A1 is located at the lowest position of the rear window of the vehicle 100 and corresponds to a distance P1 closest to the vehicle 100.

[0296] The display area A2 is located at the second lowest position of the rear window of the vehicle 100 and corresponds to a distance P2 that is the second closest to the vehicle 100.

[0297] The display area A4 is located at the highest position of the rear window of the vehicle 100 and corresponds to a distance P4 that is furthest away from the vehicle 100.

[0298] The display area A3 is located at the second highest position of the rear window of the vehicle 100 and corresponds to a distance P3 that is the second furthest away from the vehicle 100.

[0299] For example, when the determination unit 31 determines that the situation inside and outside the vehicle satisfies a display start condition of certain display information, the determination unit 31 outputs, in addition to the display information corresponding to the display start condition, the moving direction of a moving object (a pedestrian or the like) around the vehicle, its moving speed, and a distance between the moving object and the vehicle 100, which are acquired by the information acquiring unit 30, to the control unit 32.

[0300] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display start condition, the control unit 32 specifies the position of the moving object based on the moving direction of the moving object, its moving speed, and a distance between the vehicle 100 and the moving object. The control unit 32 starts displaying the display information in a display area corresponding to the specified position of the moving object among the display areas A1 to A4 of the rear window by controlling the lighting device 4b.

[0301] As a display change condition of the display information, a situation may be set in which a moving object in the surroundings of the vehicle approaches the vehicle 100.

[0302] For example, if it is detected that the moving object in the surroundings of the vehicle is approaching the vehicle 100 after displaying the above display information, the determination unit 31 determines that the situation inside and outside the vehicle meets the display change condition. At this time, the determination unit 31 outputs the moving direction of the moving object, its moving speed, and a distance between the vehicle 100 and the moving object, which are acquired by the information acquisition unit 30, to the control unit 32.

[0303] When the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display change condition, the control unit 32 specifies the position of the moving object based on the moving direction of the moving object, its moving speed, and a distance between the vehicle 100 and the moving object. The control unit 32 changes the display position of the display information to a display area corresponding to the specified position of the moving object among the display areas A1 to A4 of the rear window by controlling the lighting device 4b.

[0304] As described above, the display position of the display information is changed depending on a distance from the vehicle 100 to a target person outside the vehicle, and therefore, the target person outside the vehicle can easily visually recognize the display information. Fig. 15, the display information is displayed at a high position on the rear window in such a manner that a target person located far from the vehicle 100 can easily visually recognize the display information.

[0305] As described above, in the irradiation device 3 according to the first embodiment, when it is determined that the information regarding the situation inside and outside the vehicle conforms to a display change condition, the control unit 32 changes the display mode of the information displayed outside the vehicle by controlling the lighting device 4a or the lighting device 4b. As a result, information can be displayed in a display mode corresponding to the situation inside and outside the vehicle, and a target person outside the vehicle can be accurately informed of the information displayed outside the vehicle. Second embodiment.

[0306] In a second embodiment, a configuration is described in which a person in a vehicle is notified of information displayed outside the vehicle.

[0307] The configuration of an irradiation apparatus according to the second embodiment is basically the same as that shown in the Fig. 1 and Fig. 2 illustrated configuration of the first embodiment. Therefore, the second embodiment will also refer to Fig. 1 for a hardware configuration, and on Fig. 2 is referred to for a functional configuration. Next, the operation is described.

[0308] Fig. 16 is a flowchart illustrating the operation of an irradiation device 3 according to the second embodiment of the present invention. First, similarly to the first embodiment, the control unit 32 displays information outside a vehicle by controlling a lighting device 4a or a lighting device 4b (step ST1a).

[0309] Subsequently, the control unit 32 notifies a person in the vehicle that information outside the vehicle has been displayed by controlling the lighting device 4c and / or an in-vehicle monitor 2i (step ST2a).

[0310] Fig. 17 is a diagram illustrating a lighting state of a door handle lamp 101a in the second embodiment, and illustrates the interior of a vehicle 100. The vehicle 100 includes a door handle lamp 101a having the Fig. 1. The door handle lamp 101a is an in-vehicle lamp for emitting light within the vehicle and illuminating a door handle 101 within the vehicle.

[0311] The irradiation device 3 according to the second embodiment illuminates the door handle lamp 101a in response to displaying display information indicating a vehicle state in which a door having the door handle 101 is about to be opened outside the vehicle.

[0312] For example, if a determination unit 31 determines that the situation inside and outside the vehicle satisfies a display start condition of the above display information, the control unit 32 of the irradiation device 3 instructs a lamp driver 4c1 to illuminate the door handle lamp 101a of the door about to be opened. As a result, the lamp driver 4c1 illuminates the door handle lamp 101a according to the instruction from the control unit 32.

[0313] It should be noted that the light emitted by the door handle lamp 101a may be flashed.

[0314] A passenger of the vehicle can confirm that the display information regarding the opening of the door is displayed outside the vehicle by visually recognizing a lighting state of the door handle lamp 101a.

[0315] That is, the occupant can determine a next action to be taken after confirming the situation where the display information draws the attention of a person outside the vehicle to open the door.

[0316] Note that the case where the door handle lamp 101a is illuminated has been described, but the in-vehicle lamp illuminated according to the display information is not limited to the door handle lamp 101a.

[0317] The same effect can be achieved with an in-vehicle lamp placed at a location within the field of vision of the occupant attempting to open the door.

[0318] Fig. 18 is a diagram illustrating a state in which display information 8a for notifying a person outside the vehicle 100 of a vehicle state in which the vehicle 100 is about to move backward is displayed on an in-vehicle monitor 102, and illustrates the interior of the vehicle 100. The display information 8a shown in Fig. The in-vehicle monitor 102 illustrated in Figure 18 is a monitor that allows a passenger to visually recognize the information displayed on the display 102a, and is achieved, for example, by the in-vehicle monitor 2i of the in-vehicle navigation system 1p. The display on the in-vehicle monitor 102 is controlled by the overall control ECU 2.

[0319] In response to displaying the display information 8a corresponding to a vehicle state in which the vehicle 100 is about to move backward outside the vehicle, the irradiation device 3 according to the second embodiment instructs the overall control ECU 2 to display the display information 8a on the in-vehicle monitor 102.

[0320] For example, when the determination unit 31 determines that the situation inside and outside the vehicle satisfies a display start condition of the display information 8a, the control unit 32 instructs the overall control ECU 2 to display the display information 8a on the in-vehicle monitor 102. As a result, the overall control ECU 2 displays the display information 8a on the in-vehicle monitor 102 according to the instruction from the control unit 32.

[0321] An occupant of the vehicle can confirm that the display information regarding the backward movement of the vehicle 100 is displayed outside the vehicle by visually recognizing the display on the in-vehicle monitor 102.

[0322] That is, the occupant can determine an action to be performed next after confirming the situation where the display information draws the attention of a person outside the vehicle to the backward movement of the vehicle 100.

[0323] It should be noted that Fig. 18 illustrates the case where the display information 8a is displayed while being superimposed on the situation behind the vehicle 100 displayed on the in-vehicle monitor 102, but no limitations are intended therefor.

[0324] For example, an in-vehicle lamp disposed in the interior of a tailgate door of the vehicle 100, a lamp attached to an in-vehicle monitor, or a lamp attached to an outside mirror may be illuminated according to the display of the display information 8a.

[0325] Fig. 19 is a diagram illustrating a state in which image information 12 corresponding to a vehicle state in which a door of the vehicle is about to be opened is displayed on a rearview mirror monitor, and illustrates the interior of the vehicle 100. The rearview mirror monitor 103 is a monitor mounted on the rearview mirror of the vehicle 100. The display on the rearview mirror monitor 103 is controlled by the overall control ECU 2.

[0326] The irradiation device 3 according to the second embodiment instructs the overall control ECU 2 to display the image information 12 on the rearview mirror monitor 103 in response to the display of the display information corresponding to a vehicle state in which a door of the vehicle is about to be opened.

[0327] For example, when the determination unit 31 determines that the situation inside and outside the vehicle satisfies a display start condition of the above display information, the control unit 32 instructs the overall control ECU 2 to display the image information 12 on the rearview mirror monitor 103. As a result, the overall control ECU 2 displays the image information 12 on the rearview mirror monitor 103 according to the instruction from the control unit 32.

[0328] The image information 12 is an image (around view or bird's eye view) that overlooks the vehicle 100 and displays the above display information outside the vehicle.

[0329] A vehicle occupant can confirm that the display information regarding the opening of the vehicle door is displayed outside the vehicle by visually recognizing the display on the rearview mirror monitor 103. That is, the occupant can determine a next action after confirming the situation where the image information 12 draws the attention of a person outside the vehicle to the opening of the door.

[0330] Fig. 20 is a diagram illustrating a state in which image information 13 corresponding to a vehicle state in which a door of the vehicle is about to be opened is displayed on the in-vehicle monitor 102.

[0331] As in Fig. 20, the image information 13 is an image obtained by combining an image overlooking the vehicle 100 and displaying the display information outside the vehicle (animation is displayed on a road surface) with an image of the vehicle 100 displaying the display information outside the vehicle (displays on the rear window) as viewed from the rear.

[0332] An occupant of the vehicle can confirm that the display information regarding the opening of a door of the vehicle is displayed outside the vehicle by visually recognizing the image information 13.

[0333] Now again referring to the description of Fig. 16. The control unit 32 confirms whether the display of information outside the vehicle has ended (step ST3a). If the determination unit 31 determines that the situation inside and outside the vehicle does not satisfy a display termination condition, the control unit 32 proceeds to display information outside the vehicle (step ST3a; NO). In this case, the control unit 32 repeats the process from step ST3a. While this process is being performed, the display of information outside the vehicle and the notification in the vehicle continue.

[0334] Meanwhile, when the determination unit 31 determines that the situation inside and outside the vehicle satisfies the display termination condition, the control unit 32 terminates the display of the information outside the vehicle by controlling the lighting device 4a or the lighting device 4b. Fig. 21A is a diagram illustrating display information 6a for notifying a person outside the vehicle 100 of a vehicle state in which the left rear door is about to be opened, and illustrates the vehicle 100 as viewed from above. Fig. Fig. 21B is a diagram linking a lighting state of the door handle lamp 101a with the display of the display information 6a of Fig. 21A illustrates, and illustrates the interior of the vehicle 100. When the situation inside and outside the vehicle satisfies a display start condition of the display information 6a, the control unit 32 displays the display information 6a by controlling the lighting device 4a, as shown in Fig. 20A. As shown in Fig. 21B, the door handle lamp 101a starts lighting at the time when the display of the display information 6a is started.

[0335] Subsequently, the control unit 32 determines whether a certain time has elapsed after the end of displaying the information outside the vehicle (step ST4a).

[0336] If a certain time has not elapsed after the end of displaying the information outside the vehicle (step ST4a; NO), the control unit 32 repeats the process from step ST4a. While this process is being performed, the notification in the vehicle continues. Fig. 22A is a diagram illustrating a state immediately after the end of displaying the display information 6a for notifying a person outside the vehicle of a vehicle state in which the left rear door is about to be opened, and illustrates the vehicle 100 as viewed from above. Fig. Fig. 22B is a diagram showing an illumination state of the door handle lamp 101a in the state of Fig. 22A illustrates, and illustrates the interior of the vehicle 100. When the situation inside and outside the vehicle satisfies a display termination condition of the display information 6a, the control unit 32 terminates the display of the display information 6a by controlling the lighting device 4a, as shown in Fig. 22A. If a certain time has not elapsed after the end of displaying the display information 6a, the door handle lamp 101a continues to be illuminated as shown in Fig. 22B illustrates.

[0337] If a certain period of time has elapsed after the end of displaying the information outside the vehicle (step ST4a; YES), the control unit 32 ends the notification in the vehicle by extinguishing the door handle lamp 101a (step ST5a).

[0338] Fig. 23A is a diagram illustrating a state in which a certain time has elapsed after the end of displaying the display information 6a for notifying a person outside the vehicle of a vehicle state in which the left rear door is about to be opened, and illustrates the vehicle 100 as viewed from above. Fig. Fig. 23B is a diagram showing an illumination state of the door handle lamp 101a in the state of Fig. 23A illustrates and illustrates the interior of the vehicle 100.

[0339] When a certain time (about three seconds) has elapsed after the end of displaying the display information 6a, the door handle lamp 101a goes out, as shown in Fig. 23B illustrates.

[0340] For example, when a certain time has elapsed after the display of the display information 6a has ended, the control unit 32 instructs the lamp driver 4c1 to extinguish the door handle lamp 101a. The lamp driver 4c1 extinguishes the door handle lamp 101a according to the instruction from the control unit 32.

[0341] A passenger of the vehicle can confirm that the display information 6a regarding the opening of the door is displayed outside the vehicle by visually recognizing a lighting state of the door handle lamp 101a.

[0342] However, if the door handle lamp 101a is extinguished immediately after the display of the display information 6a ends, the occupant may feel uncomfortable about whether the vehicle is in an external situation that does not require attracting attention with the display information 6a.

[0343] Therefore, the inventor of the present invention conducted intensive studies and experiments on a relationship between a display outside a vehicle and a notification in the vehicle, and as a result, found that the above-described discomfort of the occupant can be reduced by continuing the notification in the vehicle for a certain time (about three seconds) after the end of the display of the information outside the vehicle.

[0344] That is, the Fig. The operation illustrated in Fig. 16 is obtained by integrating a new finding discovered by the inventor into the operation of the irradiation device 3.

[0345] Note that it has been described that the illumination of the door handle lamp 101a is continued until a certain time has elapsed, but the discomfort of the occupant can be similarly reduced by continuing to display it also on the screen on the in-vehicle monitor 102 and the screen on the rearview mirror monitor 103.

[0346] As described above, in the irradiation device 3 according to the second embodiment, the control unit 32 causes the door handle lamp 101a, the in-vehicle monitor 102, and the rearview mirror monitor 103 to notify a person in the vehicle that the display information is being displayed outside the vehicle. As a result, a vehicle occupant can confirm that the display information is being displayed outside the vehicle by visually recognizing it.

[0347] In the irradiation device 3 according to the second embodiment, the control unit 32 causes the door handle lamp 101a, the in-vehicle monitor 102, and the rearview mirror monitor 103 to continue the notification in the vehicle until a certain time has elapsed after the end of displaying the display information outside the vehicle.

[0348] As a result, the occupant's discomfort about whether the vehicle is in an external situation that does not require gaining attention with the display information can be reduced. Third embodiment.

[0349] In a third embodiment, a configuration is described in which the blinking of a light pattern of an animation to be displayed outside a vehicle is controlled according to a lamp directed outside the vehicle.

[0350] The configuration of an irradiation apparatus according to the third embodiment is basically the same as that shown in the Fig. 1 and Fig. 2 illustrated configuration of the first embodiment. Therefore, the third embodiment will also refer to Fig. 1 for a hardware configuration, and on Fig. 2 is referred to for a functional configuration. Next, the operation is described.

[0351] Fig. 24 is a flowchart illustrating the operation of an irradiation device 3 according to the third embodiment of the present invention. First, similar to the first embodiment, a control unit 32 displays an animation outside a vehicle by controlling a lighting device 4a. At this time, the control unit 32 confirms whether or not both the illumination of a vehicle-extending lamp and the display of an animation outside the vehicle are performed (step ST1b).

[0352] If no illumination of a lamp directed outside the vehicle is performed, but only displaying an animation outside the vehicle is performed (step ST1b; NO), the control unit 32 repeats the process of step ST1b.

[0353] Fig. 25 is a diagram illustrating vehicle-external directed lamps 103a, 103b, 104a, 104b, 105a and 105b and display information 6a in the third embodiment.

[0354] In Fig. 25, the lamps 103a, 103b, 104a, 104b, 105a and 105b directed towards the outside of the vehicle are the lamps 4d2, which in the Fig. 1, and their illumination is controlled by a lamp driver 4d1. The vehicle-externally directed lamps 103a and 103b are turn signal lamps of a vehicle 100, the vehicle-externally directed lamps 104a and 104b are exterior mirror lamps of the vehicle 100, and the vehicle-externally directed lamps 105a and 105b are hazard warning lamps or brake lamps of the vehicle 100. The display information 6a is an animation in which several light patterns flash, as in Fig. 4A illustrates.

[0355] When the display information 6a is displayed while light emitted from a lamp directed outside the vehicle is flashing, uneven flashing light is generated in some flashing patterns of the display information 6a.

[0356] In this case, a person in the vicinity of the vehicle may be dazzled, the visibility of the display information 6a may be reduced, and it may be impossible to attract sufficient attention.

[0357] Therefore, if both the illumination of an off-vehicle lamp and the display of an animation outside the vehicle are performed (step ST1b; YES), when a light pattern of the animation is flashed while the off-vehicle lamp is flashing, the control unit 32 matches the illumination timing of a light pattern of the animation with the illumination timing of the off-vehicle lamp, or alternately illuminates the off-vehicle lamp and the light pattern of the animation by controlling the lighting device 4a (step ST2b).

[0358] As a result, glare caused by uneven flashing light is prevented and the visibility of the animation is improved.

[0359] Fig. Figure 26 is a diagram illustrating a flashing pattern of a lamp directed externally to the vehicle. Fig. 27A is a diagram illustrating a flashing pattern (pattern A) of the display information 6a in the third embodiment. Fig. 27B is a diagram illustrating a flashing pattern (pattern B) of the display information 6a in the third embodiment.

[0360] As in Fig. For example, as illustrated in Figure 26, the lamp directed outward from the vehicle has a flashing pattern in which the illumination and extinction are repeated at intervals of 0.5 seconds. As shown in Fig. As illustrated in Figure 27A, the display information 6a has a flashing pattern (pattern A) in which the lighting and extinguishing are repeated at intervals of 0.5 seconds as a light pattern. It should be noted that, as shown in Fig. 27B, the display information 6a may have a flashing pattern (pattern B) in which lighting up and extinguishing are repeated at intervals of 0.25 seconds as a light pattern.

[0361] Please note that these are only examples and the flashing pattern of the display information can be freely set.

[0362] Fig. Figure 28A is a diagram illustrating a flashing pattern of a vehicle-external directed lamp. Fig. Fig. 28B is a diagram illustrating a flashing pattern (pattern A) of the display information 6a in which illumination is simultaneously with the vehicle-external directed lamp in Fig. 28A is repeated. Fig. 29A is a diagram illustrating a flashing pattern of a vehicle-external directed lamp. Fig. Fig. 29B is a diagram illustrating a flashing pattern (pattern B) of the display information 6a in which illumination is simultaneously with the vehicle-external directed lamp in Fig. 29A is repeated. As in the Fig. 28A, Fig. 28B, Fig. 29A and Fig. 29B illustrates that when the flashing pattern of the display information 6a is a pattern in which the illumination is repeated simultaneously with the lamp directed outward from the vehicle, no uneven flashing light is generated, and a person around the vehicle is not dazzled.

[0363] However, if the flashing pattern of the display information 6a causes illumination earlier than the illumination timing of the vehicle-external directed lamp, uneven flashing light is generated, causing glare.

[0364] Therefore, when the lighting timing of the display information 6a is earlier than that of the vehicle-external directed lamp, the control unit 32 performs a correction to match the lighting timing of the display information 6a with that of the vehicle-external directed lamp by lengthening the lighting time of the light pattern of the display information 6a.

[0365] Fig. Figure 30A is a diagram illustrating a flashing pattern of a lamp directed externally to the vehicle. Fig. 30B is a diagram illustrating a corrected flashing pattern (pattern A) of the display information 6a earlier than the lighting timing of the vehicle-external directed lamp in Fig. 30A was illuminated. If the illumination timing of the display information 6a is earlier than that of the vehicle-external directed lamp, the control unit 32 extends the illumination time of pattern A by a time T1 by controlling the lighting device 4a. As a result, the illumination timing of the display information 6a can be aligned with the illumination timing of the vehicle-external directed lamp. Note that the time T1 is approximately (1 - x) seconds.

[0366] Fig. 31A is a diagram illustrating a flashing pattern of a vehicle-external directed lamp. Fig. 31B is a diagram illustrating a corrected flashing pattern (pattern B) of the display information 6a earlier than the lighting timing of the vehicle-external directed lamp in Fig. 31A was illuminated. If the illumination timing of the display information 6a is earlier than that of the vehicle-external directed lamp, the control unit 32 extends the illumination time of the light pattern B by a time T2 by controlling the lighting device 4a. As a result, the illumination timing of the display information 6a can be aligned with the illumination timing of the vehicle-external directed lamp. Note that the time T2 is approximately (1 - y) seconds.

[0367] In addition, if the flashing pattern of the display information 6a causes illumination later than the illumination timing of the vehicle-external directed lamp, uneven flashing light is generated, causing glare.

[0368] Therefore, when the lighting timing of the display information 6a is later than that of the vehicle-external directed lamp, the control unit 32 performs a correction to match the lighting timing of the display information 6a with that of the vehicle-external directed lamp by shortening the extinguishing time of the light pattern of the display information 6a.

[0369] Fig. 32A is a diagram illustrating a flashing pattern of an externally directed lamp. Fig. 32B is a diagram illustrating a corrected flashing pattern (pattern A) of the display information 6a, which is later used as the lighting timing of the vehicle-external directed lamp in Fig. 32A was illuminated. When the illumination timing of the display information 6a is later than that of the vehicle-external directed lamp, the control unit 32 shortens the extinction time of the pattern A by a time T3 by controlling the lighting device 4a. As a result, the illumination timing of the display information 6a can be aligned with the illumination timing of the vehicle-external directed lamp.

[0370] Fig. 33A is a diagram illustrating a flashing pattern of a vehicle-external directed lamp. Fig. 33B is a diagram illustrating a corrected flashing pattern (pattern B) of the display information 6a, which is later used as the lighting timing of the vehicle-external directed lamp in Fig. 33A was illuminated. When the illumination timing of the display information 6a is later than that of the vehicle-external directed lamp, the control unit 32 shortens the extinction time of the pattern B by a time T4 by controlling the lighting device 4a. As a result, the illumination timing of the display information 6a can be aligned with the illumination timing of the vehicle-external directed lamp.

[0371] The control unit 32 can alternately illuminate the vehicle-external lamp and the information display light pattern 6a by extending the illumination time of the information display light pattern 6a. This can also prevent glare to a person around the vehicle without generating uneven flashing light.

[0372] Fig. 34A is a diagram illustrating a flashing pattern of an externally directed lamp. Fig. 34B is a diagram illustrating a flashing pattern (pattern A) of the display information 6a in which the lighting timing has been corrected in such a manner that the display information 6a is flashed alternately with the vehicle-externally directed lamp in Fig. 34A. When the lighting timing of the display information 6a is earlier than that of the vehicle-external lamp, the control unit 32 extends the lighting time of the pattern A by controlling the lighting device 4a. As a result, the vehicle-external lamp and the light pattern of the display information 6a can be alternately illuminated.

[0373] Fig. 35A is a diagram illustrating a flashing pattern of a vehicle-external directed lamp. Fig. 35B is a diagram illustrating a flashing pattern (pattern B) of the display information 6a in which the lighting timing has been corrected in such a manner that the display information 6a is flashed alternately with the vehicle-externally directed lamp in Fig. 35A. When the lighting timing of the display information 6a is earlier than that of the vehicle-external lamp, the control unit 32 shortens the extinction time of the pattern B by controlling the lighting device 4a. As a result, the vehicle-external lamp and the light pattern of the display information 6a can be alternately illuminated.

[0374] As described above, in the irradiation device 3 according to the third embodiment, when both the vehicle-extending lamp and the animation light pattern are flashing, the illumination timing of the animation light pattern is consistent with the illumination timing of the vehicle-extending lamp. As a result, uneven flashing light is not generated, and glare to a person around the vehicle can be prevented. The visibility of the animation is also improved.

[0375] In the irradiation device 3 according to the third embodiment, when both the vehicle-external lamp and the animation light pattern are flashed, the vehicle-external lamp and the animation light pattern are alternately illuminated. Such a configuration can also prevent glare to a person around the vehicle without generating uneven flashing light. The visibility of the animation is also improved.

[0376] The case where the control unit 32 aligns the lighting timing of the animation light pattern with the lighting timing of the off-vehicle lamp, or alternately illuminates the off-vehicle lamp and the animation light pattern by dynamically controlling the lighting device 4a, has been described. However, this is not intended to be limited. For example, the control unit 32 may display an animation in which the lighting timing of the light pattern matches the lighting timing of the off-vehicle lamp in advance in the lighting device 4a, or may display an animation of a blinking pattern that alternately illuminates the off-vehicle lamp in the lighting device 4a.

[0377] It should be noted that in the third embodiment, the blinking control of the display information immediately after the “display start of the display information” illustrated in the first embodiment was described as an example, but also the blinking control of the display information may be equally performed “when the display mode of the display information is changed” and “when the display mode is changed and then returned to the original display mode again” according to the illumination of the vehicle-external directed lamp.

[0378] It should be noted that the present invention is not limited to the above embodiments, and the embodiments can be freely combined with each other, any component in the embodiments can be modified, or any component in the embodiments can be omitted within the scope of the present invention.
