  • the long distance is such a distance that it is not necessary to inform the driver of the oncoming vehicle 210 of the presence of the pedestrian 320.
  • the intermediate distance is a distance that needs to inform the driver of the oncoming vehicle 210 of the presence of the pedestrian 320 but is considered to be less urgent.
  • the short distance is a distance that needs to inform the driver of the oncoming vehicle 210 of the presence of the pedestrian 320 and is considered to be highly urgent.
  • the headlamp control unit 11 c can detect the distance between the vehicle 100 c and the oncoming vehicle 210 based on the detection result from the oncoming vehicle detection unit 50.
  • the headlamp control unit 11c uses the first threshold value and the second threshold value related to the preset distance, and the distance between the vehicle 100c and the oncoming vehicle 210 is any of long distance, medium distance, and short distance. Can be determined.
  • the relationship between the first threshold and the second threshold is first threshold> second threshold.
  • the headlamp control unit 11c determines that the distance between the vehicle 100c and the oncoming vehicle 210 exceeds the first threshold, and determines that the distance is long. If the distance does not exceed the first threshold but exceeds the second threshold, It is determined as a medium distance, and it is determined as a short distance when the first threshold value and the second threshold value are not exceeded.
  • the headlamp control unit 11c executes processing shown in the flowchart of FIG. 23 in steps S17 and S18.
  • step S50 it is determined whether the oncoming vehicle position is a long distance.
  • the headlamp control unit 11c determines whether or not the oncoming vehicle 210 is far away from the vehicle 100c based on whether or not the distance between the vehicle 100c and the oncoming vehicle 210 has reached the first threshold value. .
  • the headlamp control unit 11c determines that the oncoming vehicle 210 is at a long distance, and ends the processing shown in the flowchart of FIG. To do. If the headlamp control unit 11c determines that the distance is a long distance, the process returns to step S10 in FIG. 18 without drawing the alarm marks 131 and 132.
  • the headlamp control unit 11c determines that there is a pedestrian in step S16, if the distance between the vehicle 100c and the oncoming vehicle 210 is a predetermined distance, the alarm marks 131 and 132 are displayed. Is not drawn (drawing part). That is, even if the headlamp control unit 11c controls the headlamp 10c so that it is dimmed, and the detection result in step S16 indicates that there is an obstacle, the oncoming vehicle 210 When the position of is a long distance, the alarm marks 131 and 132 are not drawn. Therefore, the headlamp control unit 11c can suppress the drawing of the alarm marks 131 and 132 at unnecessary timing.
  • step S51 it is determined whether the oncoming vehicle position is a medium distance.
  • the headlamp control unit 11c determines whether the oncoming vehicle 210 is at a medium distance from the vehicle 100c based on whether the distance between the vehicle 100c and the oncoming vehicle 210 has reached the second threshold value. . If the distance between the vehicle 100c and the oncoming vehicle 210 has reached the second threshold value, the headlamp control unit 11c determines that the oncoming vehicle 210 is at a medium distance and proceeds to step S53. If the distance between the vehicle 100c and the oncoming vehicle 210 has not reached the second threshold value, the headlamp control unit 11c determines that the oncoming vehicle 210 is at a short distance and proceeds to step S52.
  • step S52 the alarm mark blinking cycle is shortened.
  • the headlamp control unit 11c draws the alarm marks 131 and 132 by blinking, and shortens the blinking cycle of the alarm marks 131 and 132.
  • step S53 the flashing cycle of the alarm mark is lengthened.
  • the headlamp control unit 11c draws the alarm marks 131 and 132 by blinking, and lengthens the blinking cycle of the alarm marks 131 and 132.
  • the short length indicates the relative length of time. That is, the headlamp control unit 11c shortens the lighting cycle when the distance between the vehicle 100c and the oncoming vehicle 210 is a short distance than when the distance is a medium distance. It can also be said that the headlamp control unit 11c shortens the blinking cycle of the alarm marks 131 and 132 as the distance between the vehicle 100c and the oncoming vehicle 210 decreases.
  • the headlamp control unit 11c can achieve the same effect as that of the modified example 8. Further, the headlamp control unit 11c can draw the alarm marks 131 and 132 at a necessary timing while suppressing the drawing of the alarm marks 131 and 132 at an unnecessary timing. Further, the headlamp control unit 11c shortens the blinking cycle of the alarm marks 131 and 132 when the vehicle 100c and the oncoming vehicle 210 are close to each other, so that the driver of the oncoming vehicle 210 can be surely connected to the pedestrian 320. You can call for presence.
  • the headlamp control unit 11c may change the blinking cycle of the alarm marks 131 and 132 in three or more stages according to the distance between the vehicle 100c and the oncoming vehicle 210. For example, as the distance between the vehicle 100c and the oncoming vehicle 210 approaches, the blink cycle of the alarm marks 131 and 132 may be gradually shortened.
  • FIG. 24 is an image diagram when a warning mark is drawn.
  • FIG. 25 is an image diagram when a warning mark is drawn and after a predetermined time has elapsed from the time point of FIG.
  • the headlamp control unit of the modified example 13 draws so that the size of the alarm marks 131 and 132 seen from the oncoming vehicle 210 is constant and the direction of the alarm marks 131 and 132 is constant (drawing unit). That is, the headlamp control unit of the modified example 13 draws the warning marks 131 and 132 by changing the shapes according to the distance between the vehicle 100c and the oncoming vehicle 210 (drawing unit). In this case, the alarm marks 131 and 132 change as shown in FIGS. 24 and 25 when viewed from above. By doing so, the driver of the oncoming vehicle 210 always sees the alarm marks 131 and 132 in the same size and in the same direction.
