The invention discloses an automobile brake lamp automatic lightening method and system and an automobile. The method comprises the steps that a video image in front of the automobile is obtained through an automobile data recorder and transmitted to an automobile lamp controller, meanwhile, the automobile lamp controller reads the whole automobile speed and the gear of an ignition switch, the state of the ignition switch is judged firstly, and then the automobile speed is judged; when the vehicle speed is larger than a set value and the ignition switch is in an ON gear, the video image is analyzed, and whether the brake lamp of the vehicle is automatically lightened or not is determined by judging the lightening condition of the brake lamp of the front vehicle. The existing automobile data recorder and the like of the whole automobile are directly utilized from hardware, additional cost is not increased, the development period is shortened, and the matching difficulty is reduced. Meanwhile, a more reasonable design is made on control logic, the calculation burden brought by analysis of a large number of video images can be reduced, and the control task execution burden of the system is relieved.
本发明公开一种汽车制动灯自动点亮方法、系统及车辆,所述方法是通过行车记录仪获取车辆前方视频图像并传输给车灯控制器,同时车灯控制器读取整车车速及点火开关档位,先判定点火开关状态,然后判断车速,当车速大于设定值且点火开关处于ON档时,再对视频图像进行分析,通过判定前车制动灯点亮情况来决定是否自动点亮本车制动灯。本发明从硬件上直接利用整车已有行车记录仪等,不增加额外的成本,缩短开发周期,降低匹配难度。同时本发明在控制逻辑上做出了更为合理的设计,可以减少对大量视频图像进行分析所带来的计算负担,并减轻系统的控制任务执行负担。
