An automobile lamp control system, a control method and an automobile, the system comprises a tail lamp (3), a plurality of automobile lamp connecting lines (2), an automobile body controller (1) and a tail lamp controller (37), a plurality of automobile lamps are integrated in the tail lamp (3), each automobile lamp is provided with a signal generator (36), one end of each automobile lamp connecting line (2) is connected with the automobile lamp, and the other end of each automobile lamp connecting line (2) is connected with the automobile body controller (1); the vehicle body controller (1) is used for obtaining the distance change signal, determining a target vehicle lamp from the multiple vehicle lamps according to the distance change signal, and controlling a target signal generator (36) on the target vehicle lamp to send a PWM signal with a preset duty ratio, so that a tail lamp controller (37) controls a tail lamp (3) to execute a preset control mode based on the PWM signal with the preset duty ratio. According to the system, control over different taillight modes can be achieved through the taillight connecting line (2) which is a hard line, cost is low, expandability is good, and the problems that cost is high and expandability is low when taillight mode control is achieved through a CAN bus in the prior art are solved.

    一种车灯控制系统、控制方法及汽车,该系统包括尾灯(3)、多根车灯连接线(2)、车身控制器⑴以及尾灯控制器(37),尾灯⑶内集成有多个车灯,每个车灯上均设置有信号发生器(36),每根车灯连接线⑵均一端与车灯连接,另一端与车身控制器⑴连接;车身控制器⑴用于获取距离变化信号根据距离变化信号从多个车灯中确定目标车灯,控制目标车灯上的目标信号发生器(36)发送预设占空比的PWM信号,以使得尾灯控制器(37)基于预设占空比的PWM信号控制尾灯⑶执行预设控制模式。该系统利用车灯连接线⑵这一硬线即可实现不同尾灯模式的控制,成本低且扩展性好,解决了现有技术中通过CAN总线实现尾灯模式控制成本高且可扩展性低的问题。
