JP 2007-272350 A

  The configuration disclosed in Patent Literature 1 is configured to display a predicted traveling locus based on the steering angle of the steering wheel operated by the occupant. That is, since the predicted traveling locus is displayed on the display device when the occupant operates the steering wheel himself, the occupant can recognize in advance the traveling direction of the vehicle. However, during automatic driving in an autonomous driving vehicle, the autonomous driving vehicle autonomously travels based on surrounding conditions, and thus the occupant cannot recognize the traveling direction of the vehicle in advance. Therefore, even if the predicted traveling locus is displayed on the display device by the steering operation of the vehicle automatically, the passenger may get an impression that the behavior of the vehicle changes unexpectedly. is there. Therefore, the above prior art has room for improvement in this respect.

  In view of the above problems, an object of the present invention is to provide a display device for a vehicle in which an occupant can feel relieved during automatic driving in an autonomous driving vehicle.

  According to the first aspect of the present invention, a vehicle lower structure is provided in a vehicle that is capable of automatic driving, and is configured to detect a surrounding condition of the vehicle and information from the detection unit. In addition, an automatic operation control unit that performs automatic operation control of the vehicle during automatic operation and a vehicle interior side of a front windshield glass in the vehicle, and is present in front of the vehicle on the own lane on which the vehicle travels When the first obstacle to be detected is detected by the detection means, a first predetermined display for displaying the first obstacle, a vehicle front side of the vehicle from the lane adjacent to the own lane, and the vehicle When the second obstacle moving in the vicinity is detected by the detection means, a second predetermined display for indicating that the second obstacle has approached, and the vehicle is automatically operated by the automatic driving control unit. A third predetermined display for displaying the traveling direction of the vehicle in advance when the lane is changed from the own lane, the first obstacle is detected by the detecting means, and the vehicle is detected by the automatic driving control unit. When automatically avoiding the first obstacle, a fourth predetermined display that indicates the first obstacle and displays the traveling direction in advance is overlapped with the scenery in front of the vehicle during the automatic driving of the vehicle. Display means.

  According to the first aspect of the invention, since the display device is provided on the vehicle interior side of the front windshield glass, the display content can be displayed so as to overlap the actual scenery. Thereby, the passenger | crew can grasp | ascertain display content intuitively, without moving a eyes | visual_axis. The display means performs a first predetermined display, a second predetermined display, a third predetermined display, and a fourth predetermined display. Specifically, when the first obstacle is detected in front of the vehicle on the own lane in which the vehicle travels during automatic driving, a display indicating the first obstacle is displayed on the first predetermined point of the display means. Done by display. Therefore, the occupant can intuitively recognize which is the first obstacle at the same time that the first obstacle exists in front of the vehicle.

  Further, when the detection means detects that the second obstacle has approached the vehicle front side and in the vicinity of the vehicle from the lane adjacent to the own lane, a display indicating that the second obstacle has approached the vehicle is displayed. This is done by means of a second predetermined display of the means. Accordingly, the occupant can recognize that there is an interruption from the second obstacle, that is, another vehicle, from the adjacent lane. Therefore, as an example, when the automatic driving vehicle automatically brakes to avoid contact with another vehicle that has been interrupted from the adjacent lane, the occupant recognizes in advance by the second predetermined display that the vehicle has been interrupted. Therefore, even if the autonomous driving vehicle brakes, there is no concern about it.

  Further, when the automatic driving vehicle automatically changes the lane according to the destination, the display indicating the traveling direction of the vehicle is performed in advance by the third predetermined display of the display means. Therefore, the occupant can recognize in advance that the vehicle during automatic driving changes the lane. For this reason, even if the autonomous driving vehicle changes lanes, the passenger does not feel uneasy.

  Furthermore, when the first obstacle is detected by the detecting means and the vehicle changes its course to avoid the first obstacle by the automatic operation control unit, the first obstacle is indicated and the traveling direction for avoiding the first obstacle is indicated. The display is performed in advance by the fourth predetermined display of the display means. Therefore, the occupant can recognize in advance what causes the vehicle in automatic driving to change the course. For this reason, even if the autonomous driving vehicle changes its course, the occupant does not feel uneasy.

  The vehicle display device according to the first aspect of the present invention has an excellent effect that an occupant can feel relieved during automatic driving in an autonomous driving vehicle.

It is the schematic which shows the state which the display apparatus for vehicles performed the 3rd predetermined | prescribed display with respect to FIG. It is the schematic which shows the state which the display apparatus for vehicles performed the 4th predetermined display with respect to FIG.

  Hereinafter, an embodiment of a vehicle display device according to the present invention will be described with reference to FIGS. In these figures, the arrow OUT indicates the vehicle width direction outside, and the arrow UP indicates the vehicle vertical direction upper side.

  As shown in FIG. 1, a front windshield glass 14 is provided in front of the vehicle interior 12 of the vehicle 10. A passenger (not shown) seated in the passenger compartment 12 toward the front side of the vehicle can visually recognize the scenery in front of the vehicle through the front windshield glass 14. In addition, the vehicle 10 includes a detection unit 16 configured by a sensor or a camera (not shown) capable of detecting a situation around the vehicle 10, and an automatic driving control unit connected to the detection unit 16 by a harness (not shown). 18 are provided.

  The detection unit 16 includes a plurality of types of sensors, cameras, and the like, and detects surrounding information of the vehicle in order to perform automatic driving by the automatic driving control unit 18. The detection means detects, for example, camera imaging information, radar obstacle information, rider (LIDER) obstacle information, and the like as vehicle peripheral information. The peripheral information includes, for example, the position of the white line of the own lane 20 in which the vehicle 10 is traveling, the position of the lane center, the road width, the road shape, the obstacles around the vehicle 10, the distant situation on the front side of the vehicle, the own lane The situation of the adjacent lane 22 with respect to 20 is included. The road shape includes, for example, the curvature of the traveling lane, the change in the road surface gradient effective for estimating the sight of the sensor, and the swell. The situation of obstacles around the vehicle 10 includes, for example, information for distinguishing between a fixed obstacle and a moving obstacle, the position of the obstacle with respect to the vehicle 10, the moving direction of the obstacle with respect to the vehicle 10, and the obstacle with respect to the vehicle 10. There are relative speeds. That is, the surrounding information detection means includes the own lane 20 in which the vehicle 10 is currently traveling, the first obstacle 24 (see FIG. 2) existing in front of the vehicle on the own lane 20, the vicinity of the vehicle 10 from the adjacent lane 22 and A second obstacle 26 (see FIG. 3) that moves (so-called interruption) to the front side of the vehicle can be detected.

  The automatic driving control unit 18 controls switching between automatic driving for controlling the vehicle 10 by determining the surrounding information of the vehicle 10 and the situation of the vehicle 10 and manual driving by the occupant. During automatic driving, the automatic driving control unit 18 determines the vehicle 10 and its surrounding information based on information obtained from the detection means 16 in order to automatically drive the vehicle 10. Then, an automatic driving control process for controlling an actuator (not shown) that drives the accelerator amount, the brake amount, the steering angle, and the like is performed according to the determination result. In the automatic driving control process, a travel plan along a preset target route is generated based on the peripheral information of the vehicle 10 and the map information, and the driving is controlled so that the vehicle 10 automatically travels according to the generated travel plan. During this automatic traveling, the vehicle 10 automatically changes lanes based on the travel plan, so that it is possible to automatically travel at a branch point or a junction point on the road.

  Further, during automatic traveling, when the first obstacle 24 existing on the own lane 20 is detected, it is possible to move to the adjacent lane 22 and avoid the first obstacle 24 (see FIG. 5). The first obstacle 24 is not limited to a vehicle that does not travel, such as a failed vehicle or a construction site, and includes a vehicle that travels on the own lane 20 at a low speed (a speed lower than the vehicle 10).

  The automatic driving control unit 18 can store information indicating the traveling operation state of the vehicle 10 and output the stored information indicating the traveling operation state of the vehicle. Specifically, the automatic operation control unit 18 is connected to a HUD device 28 as a display unit by a harness (not shown). The HUD device 28 is provided in an opening 32 formed in an instrument panel 30 provided on the vehicle front side in the passenger compartment 12 and opened toward the vehicle upper side. Therefore, the image displayed on the HUD device 28 is projected onto the front windshield glass 14 through the opening 32 of the instrument panel 30. Thereby, the display content displayed by the HUD device 28 can be displayed so as to be superimposed on the scenery in the real space in front of the vehicle. In the normal traveling state, a traveling state display 33 indicating the traveling speed, shift position, drive system output amount, and the like is projected and displayed on the front windshield glass 14 by the HUD device 28.

  As shown in FIG. 2, when the first obstacle 24 is detected, an obstacle mark 34 formed in an arc shape so as to point to the first obstacle 24 as a first predetermined display is displayed on the front window. Projection display is performed at a position corresponding to the first obstacle 24 on the shield glass 14.

  Further, as shown in FIG. 3, when the second obstacle 26 is detected, a plurality of second indications indicating a direction in which the second obstacle 26 moves with respect to the vehicle 10 together with alerting are displayed. A chevron-shaped interrupt warning mark 36 in the form of an angle bracket is projected and displayed at a position corresponding to the traveling state display 33 on the front windshield glass 14.

  Furthermore, as shown in FIG. 4, when the vehicle 10 automatically changes lanes based on the travel plan generated by the automatic operation control unit 18, an arrow indicating the traveling direction is displayed as a third predetermined display. The traveling direction mark 38 of the mold is projected and displayed at a position corresponding to the own lane 20 and the lane to be changed (adjacent lane 22 in this figure) on the front windshield glass 14.

  Further, as shown in FIG. 5, when the first obstacle 24 is detected and the first obstacle 24 is avoided, the obstacle mark 34 is displayed on the front windshield glass 14 as a fourth predetermined display. Projected and displayed at a position corresponding to the first obstacle 24, and the traveling direction mark 38 is projected and displayed at a position corresponding to the own lane 20 and the lane to be changed (adjacent lane 22 in this figure) on the front windshield glass 14. Is done.

  The timing at which these displays described above are projected and displayed on the front windshield glass 14 is set to be displayed in advance before the vehicle 10 brakes or changes the course. That is, these indications are applied when the vehicle 10 detects the first obstacle 24 or the second obstacle 26 by the detecting means 16 or when the vehicle 10 is braked due to the travel plan generated by the automatic operation control unit 18. It is projected and displayed on the front windshield glass 14 in advance before the course or the course is changed.

  Next, the operation and effect of this embodiment will be described.

  In the present embodiment, as shown in FIG. 1, in a normal running state during automatic driving, the HUD device 28 displays a running state display 33 indicating the running speed, shift position, drive system output amount, etc. on the front windshield glass 14. It is displayed superimposed on the scenery in front of the vehicle. Therefore, the occupant can visually recognize the traveling operation state of the vehicle 10 without moving the line of sight toward the front of the vehicle.

  Further, the HUD device 28 performs a first predetermined display, a second predetermined display, a third predetermined display, and a fourth predetermined display by an output from the automatic operation control unit 18. Specifically, as shown in FIG. 2, when the first obstacle 24 is detected in front of the vehicle 10 on the own lane 20 where the vehicle 10 travels during automatic driving, the automatic driving control is performed. An obstacle mark 34 indicating the first obstacle 24 is projected and displayed on the front windshield glass 14 at a position corresponding to the first obstacle 24 by the output from the unit 18. Accordingly, the occupant can intuitively recognize which is the first obstacle 24 at the same time that the first obstacle 24 exists in front of the vehicle 10. In other words, as an example, when the vehicle 10 during automatic driving is braked by detecting the first obstacle 24, the occupant recognizes in advance by the obstacle mark 34 that the first obstacle 24 is in front of the vehicle 10. Therefore, even if the vehicle 10 during automatic driving is braked, there is no concern about it.

  As shown in FIG. 3, when the detection means 16 detects that the second obstacle 26 has approached (interrupted) from the adjacent lane 22 of the own lane 20 to the front side of the vehicle 10 and in the vicinity of the vehicle, An interrupt warning mark 36 indicating that the second obstacle 26 has approached the vehicle 10 is projected and displayed on the front windshield glass 14 by the HUD device 28 by the output from the automatic operation control unit 18. Therefore, the occupant can intuitively recognize from the adjacent lane 22 that the second obstacle 26, that is, the interruption of another vehicle, and in which direction the other vehicle is moving. That is, as an example, when the vehicle 10 in automatic driving is braked by an interruption of another vehicle from the adjacent lane 22, the occupant recognizes in advance that there is an interruption of another vehicle by the interruption warning mark 36. Even if the vehicle 10 during automatic driving brakes, there is no concern about it.

  Further, as shown in FIG. 4, when the vehicle 10 during automatic driving changes lanes according to the travel plan generated by the automatic driving control unit 18, the progress of the vehicle 10 by the output from the automatic driving control unit 18. A traveling direction mark 38 indicating a direction is projected and displayed in advance by the HUD device 28 at a position corresponding to the own lane 20 and the lane to be changed on the front windshield glass 14. Therefore, the occupant can intuitively recognize in advance which vehicle 10 during automatic driving changes lanes and in which direction it moves. For this reason, even if the vehicle 10 during automatic driving changes lanes, the passenger does not feel uneasy.

  Furthermore, as shown in FIG. 5, when the first obstacle 24 is on the own lane 20 and the lane is changed in order to avoid the first obstacle 24, the first output is obtained from the automatic operation control unit 18. An obstacle mark 34 pointing to the obstacle 24 is projected and displayed at a position corresponding to the first obstacle 24 on the front windshield glass 14 by the HUD device 28, and a traveling direction mark 38 indicating a traveling direction for avoidance is previously displayed. Are projected and displayed on the front windshield glass 14 at positions corresponding to the own lane 20 and the lane to be changed. Therefore, the occupant can intuitively recognize in advance what causes the vehicle 10 during automatic driving to change the course. For this reason, even if the vehicle 10 during automatic driving changes its course, the occupant does not feel uneasy. Thereby, a passenger | crew can be relieved at the time of the automatic driving | operation in an autonomous driving vehicle.

  In the present embodiment, the arc-shaped obstacle mark 34 is projected and displayed on the front windshield glass 14 as the first predetermined display. However, the present invention is not limited to this, and other shapes and display methods are used. It is good. Similarly, the interrupt warning mark 36, the traveling direction mark 38, and the obstacle mark 34 in the second predetermined display, the third predetermined display, and the fourth predetermined display may have other shapes and display methods.

  In addition, the traveling operation state and the first to fourth predetermined displays are configured to be projected and displayed on the front windshield glass 14 by the HUD device 28, but the present invention is not limited to this, and the front windshield is projected using a projector. It is good also as a structure projected and displayed on the glass 14. FIG. Furthermore, it is good also as a structure which provides projection objects, such as a combiner, between the windshield glass 14 and a passenger | crew, and is displayed on the said projection object.

  In addition, when the vehicle 10 in automatic operation detects an interruption of the second obstacle 26 from the adjacent lane 22, the vehicle 10 avoids contact with the second obstacle 26 by changing the lane in addition to braking. May be. In this case, not only the warning mark 36 but also the traveling direction mark 38 indicating the traveling direction when changing the lane is previously positioned by the HUD device 28 corresponding to the own lane 20 and the lane to be changed in the front windshield glass 14. It is good also as a structure projected and displayed.

  The embodiment of the present invention has been described above, but the present invention is not limited to the above, and various modifications other than those described above can be implemented without departing from the spirit of the present invention. Of course.
