Will be explained. In the vehicle-side block 10, the position detector 11 and the vehicle speed detector 12 constantly detect the vehicle position and the vehicle speed during traveling, and the position information and the vehicle speed information are transmitted from the transmitter / receiver 15. In the vehicle block 20, in step 100, the position information and the vehicle speed information are input to the road controller 21 via the transmitting / receiving unit 23.

This required illumination distance L1 is, for example, a free running distance of about 3 seconds as a vehicle stop distance at a normal deceleration of about 0.2 G so that it can be avoided with a margin when an obstacle is recognized on the road. Is added.

4 is illuminated. In addition, in step 130, the section L2
Before, i.e., the illuminance of the road illumination light H1 covering the portion of the vehicle headlight which has reached the illumination range is dimmed, and then in step 140, the vehicle is illuminated by the road illumination light H1.

Sよりも短くなったときには、ステップ230へ進む。On the other hand, in the meantime, in the vehicle-side block 10, the headlight controller 13 receives the vehicle speed information from the vehicle speed detector 12 in step 200, and in step 210,
The required illumination distance L1 is calculated based on the vehicle speed information. In step 220, the required illumination distance L1 is compared with the predetermined distance LS, and the required illumination distance L1 is determined by the predetermined distance L.
When it becomes shorter than S, the routine proceeds to step 230.

イバーに違和感を与える距離として予め設定される。In step 230, the headlight controller 13 controls the headlight 14 so that, as shown in FIG. 6, in addition to the illumination range I illuminated by the basic beam, at least the required illumination distance L1 Under the control of the road controller 21, the light distribution characteristic is changed so as to illuminate the range including the illumination range J of the road illumination lamp H3 which is about to be newly illuminated. This predetermined distance L
S is preset as a distance that gives the driver a feeling of strangeness when the road lighting within the range is suddenly turned on.
【0014】ステップ220での比較で、必要照明距離

路を照明するように制御される。When the required illumination distance L1 is larger than the distance LS in the comparison in step 220, the process proceeds to step 240, and the headlight 14 is controlled to illuminate the road with only the basic beam.

つき感を与えることもない。Since this embodiment is constructed as described above, of the necessary illumination distance depending on the traveling speed of the vehicle, a section exceeding the illumination range of the basic beam of the headlight 14 is successively roaded as the vehicle advances. It is illuminated by the illumination lamp H, and driving at night becomes easy. On the other hand, by the time the vehicle passes under the foremost road lighting, the road lighting is turned off, so for the driver, the road lighting suddenly disappears from the upper part of the front window to the tip of the roof. , It does not give a flicker feeling as it becomes continuous.

うなこともない。When the vehicle travels at a low speed, the required illumination distance shorter than the predetermined distance LS is not limited to the illumination range I by the basic beam, but also the road illumination lamp which is about to be turned on by the headlight 14 of the vehicle. Since the illumination range is also illuminated by the headlight 14 whose light distribution is controlled, the driver who is looking at the road surface does not feel uncomfortable when the short-distance road surface is suddenly illuminated by the road illumination lamp.
