According to the vehicle light control method and system, a vehicle comprises a warning projection lamp, the warning projection lamp projects warning light to the ground, and the warning light is located in the first direction of the vehicle; the control method comprises the steps that information about whether an object exists in a first direction of a vehicle is obtained; acquiring the distance L from the object to the vehicle; controlling the lightening state of the warning projection lamp according to the distance L: if the distance L is greater than a specific safety distance, the warning projection lamp is in a first conventional working state; if the distance L is smaller than the specific safety distance, the warning projection lamp is in a first warning working state, and the visual effect of warning light in the first normal working state is different from that in the first warning working state. And when it is judged that the distance L between the object outside the vehicle and the vehicle is too close and the collision risk exists, the state of the warning projection lamp is controlled to change so as to prompt other people or a driver of the vehicle to take danger avoiding measures to reduce the collision risk.

    提出一种车辆灯光控制方法及其控制系统,车辆包括警示投光灯,该警示投光灯向地面投射警示光,该警示光位于车辆的第一方向;控制方法包括:获本车在第一方向是否存在物体的信息;获取物体到本车的距离L;根据距离L控制警示投光灯的点亮状态,包括:若距离L大于特定安全距离,警示投光灯处于第一常规工作状态;若距离L小于特定安全距离,警示投光灯处于第一警示工作状态,其中第一常规工作状态与第一警示工作状态下的警示光的视觉效果不同。当判断车外物体到本车的距离L过近而存在碰撞风险时,控制警示投光灯出现状态变化,以提示其他人或本车驾驶员采取避险措施降低碰撞风险。
