Description

  The present invention relates to an in-vehicle device that gives a sense of security to people around a vehicle.

  In recent years, techniques for carrying out various notifications to pedestrians around a vehicle have been advanced. For example, Patent Literature 1 describes that the possibility of contact between a surrounding pedestrian and a vehicle is predicted, and when the possibility of contact is high, that fact is notified to the pedestrian.

JP 2006-163637 A

  However, from the standpoint of a pedestrian, the pedestrian feels uneasy if he / she does not know whether the approaching vehicle is detecting himself / herself. Even if the vehicle outputs the above-mentioned notification, it is difficult to know whether the notification is for itself or for other pedestrians, so the above anxiety cannot be sufficiently resolved.

  Especially at night, the driver's face and gestures are not visible to pedestrians, so the anxiety is great. In addition, there are cases where the driver is not seated in an automatic traveling vehicle that has been developed in recent years. In this case, the anxiety is particularly great. This kind of anxiety is not limited to pedestrians, but can also occur in the same way for drivers of vehicles such as bicycles and automobiles that run around the vehicle.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an in-vehicle device that reduces anxiety given to pedestrians and vehicle drivers around the vehicle.

  The invention disclosed herein employs the following technical means to achieve the above object. Note that the reference numerals in parentheses described in the claims and in this section indicate the correspondence with the specific means described in the embodiments described later, and do not limit the technical scope of the invention. .

  One of the disclosed inventions is that a specific light emitting unit (41, 51, 60a) that emits light in a specific manner is moved in the horizontal direction in a position that is visible to surrounding people (P) in the vehicle (10). A display device (20A) having a display unit (40, 50R, 50L, 60R, 60L) to be displayed so as to be visually recognized, and sensors (31, 32, 33) for detecting a positional relationship between the vehicle and a person, Control means (40a) for displaying the movement of the specific light emitting unit to stop at a display position on the side where a person is present based on the detection result of the sensor.

  According to this invention, based on the detection result of the sensor, display is performed such that the movement of the specific light emitting unit stops at the display position where the person around the vehicle is present. Therefore, the person located on the side of the specific light emitting unit that has stopped moving receives the impression that the approaching vehicle detects itself. Therefore, the anxiety that it is not known whether the approaching vehicle is detecting itself is reduced.

  Hereinafter, a plurality of modes for carrying out the present invention will be described with reference to the drawings. In each embodiment, portions corresponding to the matters described in the preceding embodiment may be denoted by the same reference numerals and redundant description may be omitted. In each embodiment, when only a part of the configuration is described, the other configurations described above can be applied to other portions of the configuration.

(First embodiment)
The vehicle 10 shown in FIG. 1 has an automatic traveling function. For example, automatic control of traveling driving force and brake, automatic control of steering, and automatic control for switching between forward and reverse are possible. The automatic traveling mode by these automatic controls and the manual traveling mode for traveling according to the driver's operation can be switched.

  The vehicle 10 includes a bonnet 11, a front grill 12, a bumper 13, and a headlight 14. The headlight 14 is located on both the left and right sides of the front grill 12 and between the bonnet 11 and the bumper 13 and is covered with a light-transmitting outer cover 15. In addition to the plurality of headlights 14, a movable device 20 described in detail later is mounted inside the outer cover 15. The movable device 20 rotates toward the person P around the vehicle 10 (see FIG. 2). The surrounding person P includes a pedestrian, a bicycle driver, a motorcycle driver, a motorcycle driver, and the like.

  As shown in FIG. 3, the movable device 20 includes a light source (LED 25) as a light emitting unit, a cover 21 that covers the LED 25, and a housing 22 that holds the LED 25 and the cover 21. The casing 22 is mounted on an inner portion of the outer cover 15 of the vehicle 10 in a state where panning and tilting operations described below can be performed. The pan operation is an operation that rotates around an imaginary line K1 extending in the vertical direction. The tilt operation is an operation that rotates around an imaginary line K2 that extends in the vehicle left-right direction (horizontal direction).

  Furthermore, the movable device 20 includes a pan motor 23 and a tilt motor 24 that move the housing 22. When the casing 22 is panned by the panning motor 23, the directions of the optical axes R and L of the LED 25 are moved to the left and right. When the casing 22 is tilted by the tilt motor 24, the directions of the optical axes R and L of the LED 25 move up and down. Furthermore, the movable device 20 includes a motor control unit 23a (drive control unit) that controls driving of the pan motor 23 and the tilt motor 24, and a light emission control unit 25a (light emission control unit) that controls driving of the LED 25.

  The vehicle 10 is equipped with a camera 31, a radar device 32, and a sonar device 33. The camera 31 photographs the surroundings of its own vehicle 10 (own vehicle). The radar device 32 and the sonar device 33 detect the positional relationship between the vehicle 10 and the object by emitting radio waves and sound waves toward the object (person P) around the vehicle 10 and receiving the reflected wave. Specifically, the distance between the vehicle 10 and the object and the direction of the object viewed from the vehicle 10 are detected.

  The approaching person detection unit 34 provided by the microcomputer detects an approaching person to the vehicle 10 based on information acquired by the camera 31, the radar apparatus 32, and the sonar apparatus 33 (sensor). For example, the approaching person detection unit 34 detects whether or not a pedestrian or a vehicle is approaching the vehicle 10 based on video data (detection result) taken by the camera 31. Further, the approaching person detection unit 34 calculates the distance between the approaching object (hereinafter referred to as approaching person) that is an approaching pedestrian or surrounding vehicle and the own vehicle based on the detection results of the radar device 32 and the sonar device 33. To do.

  The vehicle 10 includes a display unit 17 (notification unit) and an outside speaker 18 (notification unit) that notify various information to people P around the vehicle. The display unit 17 is attached to the front windshield 16 (see FIG. 1). When the display unit 17 is not driven and is not displayed, the display unit 17 is transparent. When the display unit 17 is driven, the display content of the display unit 17 can be viewed from outside the vehicle. Messages and symbols are displayed on the display unit 17. The speaker 18 outside the vehicle outputs a warning sound or a sound.

  Further, the vehicle 10 includes a vehicle drive unit 19, a vehicle behavior control unit 19 a, and a travel trajectory plan unit 35 for exhibiting the automatic travel function described above. Specific examples of the vehicle drive unit 19 include a travel motor, an actuator for a brake device, an actuator for a steering device, and the like. The traveling track planning unit 35 plans the traveling track of the host vehicle based on the host vehicle position measured by the GPS and the map information. The processing unit 36 outputs a command signal to the vehicle behavior control unit 19a so as to automatically travel on the traveling track planned by the traveling track planning unit 35. The vehicle behavior control unit 19a controls the operation of the vehicle drive unit 19 according to the command signal. As described above, the automatic traveling function is exhibited.

  When an approaching person is detected by the approaching person detection part 34, the processing part 36 has a possibility of colliding with an approaching person or more based on the traveling path calculated by the traveling path planning part 35 or the traveling state of the host vehicle. It is determined whether or not. When it is determined that there is a possibility of a collision, a command signal is output to the movable device 20, the display control unit 17a, the sound control unit 18a, and the vehicle behavior control unit 19a based on the positional relationship between the approaching person and the host vehicle. .

  For example, when the host vehicle automatically drives the approaching person to give way, the intention to give the way is notified to the approaching person by outputting signals instructing various operations exemplified below. That is, a command signal for moving the vehicle backward by a predetermined distance (for example, several centimeters) is output to the vehicle behavior control unit 19a. A command signal for changing the pseudo engine sound from the running sound to the idling sound, turning off the pseudo engine sound, or performing voice guidance such as “Please come first” is output to the voice control unit 18a. A display signal such as “Please come first” and a command signal for displaying a symbol such as an arrow are output to the display control unit 17a.

  For example, in the case of driving automatically on the premise that the vehicle gives way from an approaching person, the intention to get the way is given by outputting signals that command various operations exemplified below. Notify the approaching person. That is, a command signal for moving the vehicle forward by a predetermined distance (for example, several centimeters) is output to the vehicle behavior control unit 19a. A command signal for changing the pseudo engine sound from the idling sound to the traveling sound or for performing voice guidance such as “start” is output to the voice control unit 18a. A command signal for displaying a display guide such as “I will start” and a symbol such as an arrow is output to the display control unit 17a.

  When the above-described voice guidance is output from the outside speaker 18, the same voice guidance is also output from the in-vehicle speaker 18i. Thereby, the content of the voice guidance is also notified to the passenger of the vehicle 10.

  FIG. 4 is a flowchart showing a procedure of processing repeatedly executed at a predetermined cycle by the microcomputer providing the approaching person detection unit 34 and the processing unit 36 according to a program. In this process, when an approaching person who may possibly come into contact is detected, a notification such as a message notification is given to the approaching person, the vehicle is automatically controlled, and the movable device 20 is operated.

  Specifically, first, in step S10 of FIG. 4, the detection result by the radar device 32 and the sonar device 33 is acquired, and the image taken by the camera 31 is acquired. In subsequent step S11, the image acquired in step S10 is analyzed, and based on the analysis result, it is determined whether or not there is an approaching person such as a pedestrian approaching the own vehicle, a car, or a bicycle.

  If it is determined that an approaching person is present, in the subsequent step S12, the distance between the host vehicle and the approaching person is calculated based on the detection result acquired in step S10. In subsequent step S13, the traveling direction of the approaching person is estimated based on the transition of the detection result acquired in step S10. In subsequent step S14, based on the distance calculation result in step S12 and the estimation result of the traveling direction in step S13, it is determined whether or not the possibility that the approaching person and the host vehicle are in contact is greater than or equal to a predetermined value.

  If it is determined that the possibility of contact is greater than or equal to a predetermined value, the content of automatic driving for the approaching person is determined in the subsequent step S15, and the contents of notification to the approaching person are determined according to the content. For example, it is determined whether the host vehicle is automatically driven so as to give way to an approaching person, or the host vehicle is automatically driven so that the approaching person can give it away. If a decision to give way is made, it is determined that a display content such as “Please come first” or voice guidance is to be notified.

  In the subsequent step S16, the movable device 20 is operated according to the subroutine processing of FIG. 5 based on the distance calculation result in step S12 and the traveling direction estimation result in step S13. In the subsequent step S17, a notification process is executed so that the notification content determined in step S15 is displayed on the display unit 17 and is output by the outside speaker 18. This notification process is performed after a pan operation and a tilt operation described later are completed. In the subsequent step S18, the vehicle drive unit 19 is automatically controlled based on the content of the automatic driving determined in step S15 to control the behavior of the vehicle 10. For example, when the decision to give way is made, the vehicle drive unit 19 is automatically controlled so that the vehicle 10 is moved back by several centimeters and stopped.

  Next, the process procedure of the movable device control shown in FIG. 5 will be described. First, in step S20, the LED 25 built in the housing 22 is turned on. In a succeeding step S21, it is determined whether or not the optical axes R and L are directed in the target direction and the operation in the target direction is completed. If it is determined that the panning is not completed, the panning motor 23 and the tilting motor 24 are driven so that the optical axes R and L face the target direction in the subsequent step S22. The target direction is calculated based on the image of the camera 31 acquired in step S10 in FIG. For example, the direction in which the optical axes R and L are directed to the face of the approaching person who has been subjected to image analysis is calculated as the target direction.

  If it is determined in step S21 that the operation in the target direction has been completed, the driving of the pan motor 23 and the tilt motor 24 is stopped in the subsequent step S23. Thereafter, in step S24, the lit LED 25 is switched to blinking.

  Therefore, when the movable device control is performed, the movable device 20 operates as follows. That is, first, the LED 25 is turned on. Thereafter, the housing 22 is tilted and panned while the LED 25 is lit, and the optical axes R and L of the LED 25 are directed toward the approaching person. Thereafter, when both the tilt operation and the pan operation stop, the LED 25 blinks.

  The movable device 20 is provided on each of the left and right in the same manner as the headlight 14 in the front portion of the vehicle 10. In other words, the two movable devices 20 are arranged side by side at a predetermined interval in the horizontal direction. Specifically, the LED 25 and the housing 22 of each of the left and right movable devices 20 are disposed inside the outer cover 15 of each of the left and right headlights 14. Then, the left and right movable devices 20 start to light simultaneously, simultaneously start tilt operation and pan operation, and simultaneously start blinking.

  As described above, according to the present embodiment, the movable device 20 capable of panning operation is provided at a position that is visible to the surrounding person P in the vehicle 10. And based on the detection result by the camera 31, the radar apparatus 32, and the sonar apparatus 33, the movable device 20 is pan-operated toward an approaching person. Therefore, an approaching person who is directed to the movable device 20 receives an impression that the approaching vehicle detects itself. Therefore, the anxiety that it is not known whether the approaching vehicle is detecting itself is reduced.

  Furthermore, according to the present embodiment, two movable devices 20 are arranged in the horizontal direction with a predetermined interval. Therefore, an approaching person who is directed to the movable device 20 has an impression like a pair of eyes of an animal with respect to the two movable devices 20. Therefore, the impression that the approaching vehicle is detecting itself is more strongly received, and the above-described reduction in anxiety can be promoted.

  Furthermore, according to this embodiment, the movable device 20 has the LED 25, and the optical axes R and L of the LED 25 are also directed toward the approaching person as the casing 22 of the movable device 20 pans toward the approaching person. Thus, the LED 25 is held by the housing 22. According to this, since the LED 25 turns toward the approaching person while emitting light, the approaching vehicle receives an impression that the approaching vehicle is detecting itself more strongly, and it is possible to promote the reduction of the anxiety described above.

  Furthermore, according to the present embodiment, when the movable device 20 stops the pan operation, the LED 25 is driven in a manner different from that during the pan operation. That is, the LED 25 is turned on when the pan operation is performed, and the LED 25 is blinked when the pan operation is completed. According to this, from the standpoint of the approaching person, the movable device 20 pans toward itself, and the driving mode of the LED 25 changes after the panning operation stops at the position where the optical axes R and L are directed toward itself. Therefore, the impression that the approaching vehicle detects itself is more strongly received, and the reduction of the above-mentioned anxiety can be promoted.

  Furthermore, according to the present embodiment, the vehicle outside speaker 18 and the display unit 17 for notifying information to an approaching person are provided, and notification is started when the movable device 20 stops the pan operation or within a predetermined time from the pan operation stop time. Let According to this, from the standpoint of the approaching person, the movable device 20 pans toward itself, and the notification is started after the panning operation stops at the position where the optical axes R and L are directed toward the user. For this reason, an impression that the notification is being directed toward the user is received, and communication with the vehicle 10 is promoted. Specifically, it becomes easy to grasp that the notification of whether the vehicle 10 wants to give way or wants to give it is for itself.

  Furthermore, according to the present embodiment, the movable device 20 can also rotate around the virtual line K2 extending in the horizontal direction. Specifically, tilt operation is possible in addition to pan operation. Therefore, from the standpoint of the approaching person, the impression that the approaching vehicle detects itself is more strongly received, and the reduction of the above-mentioned anxiety can be promoted.

(Second Embodiment)
In the first embodiment, the pan operation and the tilt operation are performed while the LED 25 is lit, and the LED 25 is switched from lighting to blinking when these operations are completed. In contrast, in the present embodiment, the pan operation and the tilt operation are performed while the LED 25 is lit, and the light emission luminance of the LED 25 is increased when these operations are completed.

  Specifically, as shown in FIG. 6, after the LED 25 is turned on in step S20, the pan motor 23 and the tilt motor 24 are driven until the operation in the target direction is completed (S22). When the operation is completed, the motor is stopped (S23). In the next step S24A, the light emission luminance of the LED 25 is increased and turned on.

  As described above, according to the present embodiment, from the standpoint of an approaching person, the light emission luminance of the LED 25 is increased after the movable device 20 pans toward itself and the optical axes R and L stop operating at positions toward the user. Increase. Therefore, the impression that the approaching vehicle detects itself is more strongly received, and the reduction of the above-mentioned anxiety can be promoted.

(Third embodiment)
In the first embodiment, one LED 25 is provided in one movable device 20. In contrast, in the present embodiment, a plurality of LEDs 25 are provided in one movable device 20. And when execution of movable device control is instruct | indicated in step S16 of FIG. 4, first, in step S20 shown in FIG. 7, some LED25 will be lighted. Thereafter, the pan motor 23 and the tilt motor 24 are driven until the operation in the target direction is completed (S22), and the driving of the motor is stopped when the operation in the target direction is completed (S23). Then, in the next step S24B, all the LEDs 25 are turned on.

  As described above, according to the present embodiment, when an approaching person is detected and it is determined that there is a possibility of contact, the state shown in FIG. 9 in which all the LEDs 25 are turned off is changed to the state shown in FIG. Switch. Thereafter, the movable device 20 pans toward the approaching person, and after the panning operation is stopped at the position where the optical axes R and L are directed toward itself, the state is switched to the state of FIG. Therefore, the approaching person receives the impression that the approaching vehicle is detecting himself / herself more strongly, and can promote the reduction of the above-mentioned anxiety.

(Fourth embodiment)
In each said embodiment, the movable device 20 is pan-operated in the state which lighted LED25. On the other hand, in this embodiment, the movable device 20 is operated to pan with the LED 25 turned off. That is, when execution of the movable device control is instructed in step S16 of FIG. 4, steps S21, S22, and S23 of FIG. Then, when the operation in the target direction is completed, the LED 25 is turned on in step S24C.

  As described above, according to the present embodiment, from the standpoint of an approaching person, the movable device 20 pans toward itself, and the optical axes R and L are deactivated at positions where they are directed toward themselves. After the stop, the LED 25 that has been turned off is switched to light up. Therefore, the impression that the approaching vehicle detects itself is more strongly received, and the reduction of the above-mentioned anxiety can be promoted.

(Fifth embodiment)
The on-vehicle apparatus according to the first embodiment includes a movable device 20 that can perform a pan operation. In contrast, the in-vehicle apparatus according to the present embodiment includes the display device 20A (see FIG. 15) in which the pan motor 23, the tilt motor 24, and the motor control unit 23a illustrated in FIG.

  The display device 20 </ b> A is mounted at a position that can be seen by the surrounding person P in the vehicle 10, and displays a display unit 40 (see FIG. 12) that displays a specific light emitting unit that emits light in a specific manner in a horizontal direction. ). The display unit 40 includes a plurality of LEDs 41, 42, 43, 44, 45, 46, 47, 48, and 49 as light sources. These LEDs 41 to 48 are mounted side by side in the horizontal direction at the front portion of the vehicle 10. In the example of FIG. 12, the display unit 40 is attached below the headlight 14 and the front grill 12. Specifically, the display unit 40 is attached to the upper surface portion 13a of the bumper 13 facing upward.

  As shown in FIG. 15, the vehicle 10 according to the present embodiment is also equipped with a camera 31, a radar device 32, a sonar device 33, an approaching person detection unit 34, and a traveling track planning unit 35 similar to those in the embodiment shown in FIG. Has been. Further, the vehicle 10 includes a display unit 17, an outside speaker 18, an in-vehicle speaker 18i, and a vehicle drive unit 19 similar to those in FIG. 3, and also includes a display control unit 17a, an audio control unit 18a, and a vehicle behavior control unit 19a. The processing unit 36 determines the possibility of a collision with an approaching person in the same manner as in FIG. 3, and if it is determined that there is a collision possibility, the display control unit 17a is based on the positional relationship between the approaching person and the host vehicle. The command signal is output to the voice control unit 18a and the vehicle behavior control unit 19a.

  The display device 20 </ b> A includes a light emission control unit 40 a (control unit) that controls driving of each of the plurality of LEDs 41 to 49. The processing unit 36 outputs a command signal to the light emission control unit 40a based on the presence / absence of an approaching person and the positional relationship between the approaching person and the host vehicle. By this command signal, for example, the display content of the display unit 40 is controlled as shown in FIG. 12, FIG. 13 and FIG.

  The control of the display device 20A by this command signal is executed according to the procedure of the flowchart shown in FIG. The display device control shown in FIG. 16 replaces step S16 in FIG. Therefore, when it is determined in step S11 in FIG. 4 that there is an approaching person and it is determined in step S14 that there is a possibility of contact, the display device control in FIG. 16 is executed.

  In step S30 of FIG. 16, the LED 41 (center LED) located in the center among the plurality of LEDs 41 to 49 arranged in the left-right direction of the vehicle is turned on. Therefore, for example, as shown in FIG. 12, when an approaching person who can contact the right side in front of the vehicle 10 is detected, the central LED is turned on as shown in FIG. In continuing step S31, the display part 40 is displayed so that a lighting location may be moved toward LED45 (target LED) in a display position nearest to the approaching person P. FIG.

  Specifically, after the central LED is turned on for a predetermined time, the central LED is turned off, and the LED 42 located next to the target LED with respect to the central LED is turned on. Thereafter, after the LED 42 is turned on for a predetermined time, the LED 42 is turned off, and the LED 43 located next to the LED 42 is turned on (see FIG. 13). Thereafter, the LED 43, the LED 44, and the LED 45 are sequentially turned on in the same manner. That is, the specific light emitting unit is displayed so as to move from the central LED in the order of LED 42, LED 43, LED 44, and LED 45.

  After moving the lighting location as described above, when the target LED is lit for a predetermined time in step S32, the target LED is switched from lighting to blinking in subsequent step S33.

  As described above, according to the present embodiment, the display of the display unit 40 is changed based on the detection results of the camera 31, the radar device 32, and the sonar device 33. Specifically, a predetermined portion (specific light emitting portion) in the display area of the display unit 40 is caused to emit light in a mode different from other portions. And the specific light emission part moves within a display area, and it is made to display so that the said movement may stop in the display part (target LED) by the side where an approaching person exists among the display areas of the display part 40. FIG. Therefore, the person located on the side of the specific light emitting unit that has stopped moving receives the impression that the approaching vehicle detects itself. Therefore, the anxiety that it is not known whether the approaching vehicle is detecting itself is reduced.

  Further, according to the present embodiment, when the movement of the specific light emitting unit is stopped, the control unit displays the specific light emitting unit in a mode different from that when the specific light emitting unit is moving. Specifically, during the movement period of the specific light emitting unit, the specific light emitting unit is turned on and the other parts are turned off. Then, after the movement of the specific light emitting unit is stopped, the specific light emitting unit is blinked. According to this, from the standpoint of the approaching person, the optical axes R and L of the specific light emitting unit of the display device 20A approach toward themselves. After the optical axes R and L are sufficiently close to each other and stop moving, the driving mode of the specific light emitting unit changes from lighting to blinking. Therefore, the impression that the approaching vehicle detects itself is more strongly received, and the reduction of the above-mentioned anxiety can be promoted.

  Furthermore, according to the present embodiment, the vehicle outside speaker 18 and the display unit 17 for notifying information to an approaching person are provided, and the notification is started within a predetermined time from when the movement of the specific light emitting unit by the display device 20A is stopped or when the movement is stopped. . According to this, from the standpoint of the approaching person, the specific display unit moves toward the user, stops moving at a position sufficiently close to him, and the notification is started after the movement is stopped. For this reason, an impression that the notification is being directed toward the user is received, and communication with the vehicle 10 is promoted. Specifically, it becomes easy to grasp that the notification of whether the vehicle 10 wants to give way or wants to give it is for itself.

(Sixth embodiment)
As shown in FIG. 17, in this embodiment, two display units 50R and 50L included in the display device 20A are arranged side by side in the horizontal direction with a predetermined interval therebetween. Each of the display units 50R and 50L includes a plurality of LEDs 51, 52, 53, 54, and 55 as light sources. These LEDs 51 to 55 are mounted side by side in the horizontal direction in the front portion of the vehicle 10. In the example of FIG. 17, the display units 50 </ b> R and 50 </ b> L are attached to the inside of the outer cover 15, and also serve as a headlight (headlight) that illuminates the front of the vehicle 10. In addition, the structure of the vehicle-mounted apparatus concerning this embodiment is the same as 5th Embodiment except display part 50R, 50L.

  For example, as shown in FIG. 17, when an approaching person P who is likely to contact the right side in front of the vehicle 10 is detected, the left and right display units 50 </ b> R and 50 </ b> L are selected from the plurality of LEDs 51 to 55 arranged in the left-right direction of the vehicle. The LED 51 (center LED) located at the center is turned on. Thereafter, the display units 50R and 50L are displayed so as to move the lighting locations toward the LEDs 53 and 55 (target LEDs) at the display position closest to the approaching person P (see FIGS. 18 and 19). In the case of the display unit 50R located on the right side of the vehicle, the target LED is the LED 53 located at the right end in the display area of the display unit 50R. In the case of the display unit 50L located on the left side of the vehicle, the target LED is the LED 55 located at the right end in the display area of the display unit 50L. Then, as described above, the lighting location is moved to light the target LED for a predetermined time, and then the target LED is switched from lighting to blinking.

  When the headlights need to be turned on at night or the like, all the LEDs 51 to 55 are turned on. Then, the specific light emitting unit is turned on with higher brightness than the other light emitting units, so that the specific light emitting unit is visually recognized in a different manner from the other light emitting units. Further, the control of the notification means according to the present embodiment is the same as that of the fifth embodiment, and the notification by the display unit 17 and the outside speaker 18 is performed after the target LED is turned on.

To be displayed. Therefore, since the person who is located on the side of the specific light emitting unit that has stopped moving receives the impression that the approaching vehicle is detecting himself / herself, the same effect as in the fifth embodiment is exhibited.

  Furthermore, according to the present embodiment, two display units 50R and 50L are arranged side by side in the horizontal direction at a predetermined interval. For this reason, an approaching person who visually recognizes that the specific light emitting unit is approaching himself / herself has an impression like a pair of eyes of an animal with respect to the two display units 50R and 50L. Therefore, the impression that the approaching vehicle is detecting itself is more strongly received, and the above-described reduction in anxiety can be promoted.

  Furthermore, according to this embodiment, since the display change according to the position of the approaching person is performed using the LEDs 51 to 55 that function as headlights, the number of parts can be reduced.

(Seventh embodiment)
In the sixth embodiment, the light sources and headlights of the display units 50R and 50L are combined. On the other hand, in the present embodiment shown in FIG. 20, the light sources of the display units 60R and 60L are provided separately from the headlight 14. Specifically, the display portions 60R and 60L are attached to the upper surface portion 13a of the bumper 13 facing upward. Two of these display units 60R and 60L are also arranged side by side in the horizontal direction with a predetermined interval in the same manner as in the sixth embodiment.

  Further, as shown in FIG. 21, the display units 60R and 60L are constituted by liquid crystal display panels. Specifically, a slit 13b is formed in the upper surface portion 13a, and the display panel is disposed on the back side of the upper surface portion 13a, thereby covering the outer peripheral portion of the display panel with the upper surface portion 13a. And the specific light emission part 60a which imitated the eyeball is displayed on a display panel, and it displays so that the specific light emission part 60a may move to a vehicle left-right direction. Thereby, it seems that the eyeball moves in the left-right direction within the frame of the slit 13b.

  For example, when an approaching person P who may contact the right side in front of the vehicle 10 is detected, the specific light emitting unit 60a is displayed at the center of the display panel in each of the left and right display units 60R and 60L. Thereafter, the display units 60R and 60L are displayed so that the specific light emitting unit 60a is visually recognized so as to gradually move toward the side where the approaching person P is located. And after moving the specific light emission part 60a to a target position as mentioned above, the specific light emission part 60a is switched from lighting to blinking.

  As described above, according to the present embodiment, the specific light emitting unit 60a moves in the display area, and the movement is stopped in the display part on the side where the approaching person is present in the display areas of the display units 60R and 60L. Let Therefore, the person who is located on the side of the specific light emitting unit 60a that has stopped moving receives the impression that the approaching vehicle is detecting herself, and thus the same effect as in the sixth embodiment is exhibited.

  Furthermore, according to this embodiment, since the specific light emitting unit 60a is displayed to move using the liquid crystal display panel, the specific light emitting unit 60a can be displayed to move smoothly. Therefore, the effect of visually recognizing the eyes of the animals described above can be promoted. Furthermore, in this embodiment, the horizontal width dimension 60w of the slit 13b is set larger than the vertical dimension. Therefore, since the specific light emitting unit 60a moves in the left-right direction in the display area extending in the left-right direction of the vehicle, it can be promoted to be visually recognized like an animal eye.
