The invention relates to a dynamic steering lamp fault diagnosis system and method, a vehicle body controller and a vehicle. The system comprises a dynamic steering lamp module which comprises a leftside steering lamp module and a right side steering lamp module which are connected in parallel; the left side steering lamp module continuously outputs a left side feedback signal under the conditionthat the left side steering lamp module is in a working state; the right side steering lamp module continuously outputs a right side feedback signal under the condition that the right side steering lamp module is in a working state; and the vehicle body controller is connected with the left side steering lamp module and the right side steering lamp module which are connected in parallel, and is used for receiving the left side feedback signal or the right side feedback signal, detecting whether the left side feedback signal or the right side feedback signal is subjected to level overturning in a preset time period of each power supply period, and obtaining a fault diagnosis result according to the detection result. According to the dynamic steering lamp fault diagnosis system and method,the vehicle body controller and the vehicle, hardware resources of the vehicle body controller can be saved, the left steering lamp module and the right steering lamp module are subjected to time-sharing diagnosis, and the accuracy of fault diagnosis is improved.
本申请涉及一种流水转向灯故障诊断系统、方法、车身控制器和车辆,所述系统包括:流水转向灯模组,流水转向灯模组包括并联连接的左侧转向灯模块和右侧转向灯模块;左侧转向灯模块在处于工作状态的情况下持续输出左侧反馈信号;右侧转向灯模块在处于工作状态的情况下持续输出右侧反馈信号;车身控制器,与并联后的左侧转向灯模块和右侧转向灯模块相连接,用于接收左侧反馈信号或右侧反馈信号,并检测左侧反馈信号或右侧反馈信号在每一供电周期的预设时段内是否发生电平翻转,且根据检测的结果得到故障诊断结果。本申请可节约车身控制器的硬件资源,并对左侧转向灯模块和右侧转向灯模块进行分时诊断,提高了故障诊断的准确性。
