Then the vehicle is driven to the second position interval, and the vehicle speed still exceeds the second speed threshold value 80km/h in the second position interval, the illumination mode at the moment is changed into the second mode, the lamplight irradiates at 121-160m and forms a flickering light spot, and the light originally irradiated in the first position interval is extinguished. At this time, if the forward vehicle continues to travel to the third location section and the speed exceeds 60km/h, the light irradiation is switched to the third mode, the light irradiated on the first location section and the light irradiated on the second location section is extinguished, and the light is irradiated on the third location section and is located in front of the vehicle. If the vehicle continues to move forward and reaches the fourth position interval and the vehicle speed exceeds 50km/h specified in the fourth interval range, the light irradiation is switched to a fourth mode, the light irradiated in the first position interval, the second position interval and the third position interval is controlled to be extinguished, and the light is controlled to be irradiated in the fourth position interval in a flickering state, is positioned in the forward direction of the vehicle and is positioned in front of the vehicle.
