The invention discloses a trailer lamp control system and method. The trailer lamp control system comprises a controller A, a controller B, a controller C, a VCU, a controller box, a trailer lamp and an instrument. The controller A receives the switching value signal or the message information, performs logic judgment and sends a judgment result to the controller B; the controller B performs power detection and judgment on the load, if the power is a halogen lamp or an LED and the controller B detects that a loop has no fault, a control instruction is output to control the controller box, otherwise, the lamp state is output to the controller A, and the controller A feeds back the instrument; and the controller box controls the trailer lamp according to the control instruction, comprises a DC/DC unit and is used for realizing 24V/12V voltage conversion. When the whole vehicle is subjected to auxiliary braking, the controller C sends an auxiliary braking message to the controller A; the vehicle control unit VCU obtains a brake lamp switch signal, a reverse gear signal or a reverse gear message and sends the signals to the controller A; the invention can be matched with various overseas trailer lamp devices, and is suitable for high-power trailer lamp devices.
一种挂车灯具控制系统及方法,包括:控制器A、控制器B、控制器C、VCU、控制器盒、挂车灯具、仪表;控制器A接收开关量信号或报文信息,进行逻辑判断,将判断结果发送至控制器B;控制器B对负载进行功率检测判断,若功率为卤素灯或LED且控制器B对回路检测无故障,输出控制指令控制控制器盒,反之输出灯具状态至控制器A,控制器A反馈仪表;控制器盒根据控制指令控制挂车灯具,包括DC/DC单元,用于实现24V/12V电压转换。整车进行辅助制动时,控制器C将辅助制动报文发送至控制器A;整车控制单元VCU获取制动灯开关信号、倒档信号或倒挡报文发送至控制器A。本发明可匹配应用海外各类挂车灯具装置,适用于大功率挂车灯具装置。
