The invention relates to the field of vehicle light control, and discloses a control method of a steering lamp of a tractor and a control system of a vehicle body controller. A lightening instruction is sent to a reserved plug-in type electric connector, corresponding to a chassis, of the trailer steering lamp and a main vehicle steering lamp according to the set frequency; the vehicle body controller detects a first current value of a reserved plug-in type electric connector corresponding to the trailer steering lamp and the duration time of the corresponding current; and when the first current value is smaller than or equal to a set first current threshold value, the duration time of the first current value is larger than a first time threshold value, and the vehicle body controller detects an open-circuit fault, the main vehicle steering lamp is controlled to output normally. According to the control method of the tractor steering lamp and the control system of the vehicle body controller, the trailer steering lamp and the main vehicle steering lamp are accurately controlled without additionally arranging an external device or by means of other system signals.

    本申请涉及车辆灯光控制领域,公开了一种牵引车转向灯的控制方法及车身控制器的控制系统,控制方法包含以下步骤:车身控制器接收到转向灯的上升沿信号后,按照设定频率向挂车转向灯在底盘对应的预留插接式电连接器及主车转向灯发送点亮指令;车身控制器检测挂车转向灯对应的预留插接式电连接器的第一电流值和对应电流持续的时间;当第一电流值小于等于设定的第一电流阈值,且第一电流值持续的时间大于第一时间阈值,车身控制器检测到开路故障,则控制主车转向灯正常输出。本申请的牵引车转向灯的控制方法及车身控制器的控制系统,无需新增外部装置或者借助其它系统信号,精准控制挂车转向灯和主车转向灯。
