The invention discloses a control method for an automobile turning lighting system. The control method comprises the steps that S1, road surface information is obtained in real time; s2, judging whether the front is a curve or not, and if yes, entering S3; otherwise, returning to S1; s3, judging whether the external illumination intensity is lower than a first threshold value or not, and if yes, entering S4; otherwise, returning to S1; s4, whether a steering lamp is turned on or not is detected, and if yes, S7 is executed; otherwise, entering S5; s5, monitoring whether the head of the driver rotates left and right or not, and if yes, entering S6; otherwise, returning to S1; s6, according to the road surface information and the lane where the vehicle is located, whether a steering trend exists or not is judged, and if yes, S7 is executed; otherwise, returning to S1; and S7, the side lighting unit on the corresponding side is turned on according to the turning-on direction of the steering lamp or the steering lamp and the side lighting unit on the corresponding side are turned on according to the rotating direction of the head. Whether a driver has the turning intention or not can be judged, the side lighting unit makes a response in advance, and the risk that the side lighting unit collides with pedestrians around a vehicle body due to the fact that the side lighting unit is turned on late is reduced.
本发明公开了一种汽车转弯照明系统的控制方法,包括:S1、实时获取路面信息;S2、判断前方是否为弯道,若是,进入S3;否则回到S1;S3、判断外界光照强度是否低于第一阈值,若是,进入S4;否则回到S1;S4、检测转向灯是否开启,若是,进入S7;否则进入S5;S5、监测驾驶员头部是否左右转动,若是,进入S6;否则返回S1;S6、根据路面信息和本车所处车道,判断是否有转向趋势,若是,进入S7;否则回到S1;S7、根据转向灯开启的方向开启对应一侧的侧面照明单元或根据头部转动方向开启对应一侧的转向灯和侧面照明单元。本发明可以判断驾驶员是否具有转弯意向,使侧面照明单元提前做出响应,降低了因侧面照明单元打开较晚而撞到车身周围存在行人的风险。
