The invention provides a self-adaptive cruise control method based on light intensity, and relates to the technical field of automobile safety. The method comprises the following steps: S1, connectinga lumen detector; S2, judging whether the light intensity is not smaller than a preset threshold value or not; if yes, executing S3; otherwise, executing S5; S3, judging whether the current vehicle speed is not smaller than a first vehicle speed threshold value and whether the distance between the current vehicle and a front vehicle is not larger than a first length threshold value; if yes, sending out a warning; S4, judging whether the relative speed between the front vehicle and the current vehicle is not larger than a relative speed threshold value or not; if yes, controlling braking; otherwise, returning to S3; and S5, judging whether the current vehicle speed is not smaller than a second vehicle speed threshold value and whether the distance between the current vehicle and the frontvehicle is not larger than a second length threshold value; if yes, controlling braking; otherwise, executing S2. The adaptive cruise control method based on light intensity is simple and convenient,the performance is adjusted through the light lumen detector and the millimeter wave radar according to the lumen intensity, the safety is high, and the adaptive cruise control method can adapt to different weathers.

    本发明提供一种基于光线强度的自适应巡航调节方法,涉及汽车安全技术领域,包括:S1:连接流明度探测器;S2:判断光线强度是否不小于预定阈值;若是执行S3;反之执行S5;S3:判断是否当前车速不小于第一车速阈值且与前车之间距离不大于第一长度阈值;若是则发出警示;S4:判断前车与当前车辆之间相对速度是否不大于相对速度阈值;若是则控制制动;反之返回S3;S5:判断是否当前车速不小于第二车速阈值且与前车之间距离不大于第二长度阈值;若是则控制制动;反之执行S2。本发明一种基于光线强度的自适应巡航调节方法简单方便,通过光线流明度探测器,毫米波雷达根据流明度强弱大小来调节性能,安全性高,能够适应不同天气。
