The invention provides a vehicle lamp fault error reporting system, which comprises a vehicle lamp module circuit and a vehicle body controller, wherein the vehicle lamp module circuit comprises a vehicle lamp module, a detection module and a signal interface; the vehicle lamp module comprises a first end point and a second end point; the detection module can generate an open-circuit error reporting signal after the first level of the first end point changes, can generate a short-circuit error reporting signal after the second level of the second end point changes, and comprises a third end point used for outputting the open-circuit error reporting signal and the short-circuit error reporting signal; the signal interface comprises a fourth end point, and the third end point is connected with the fourth end point; and the vehicle body controller is connected with the signal interface. The detection module of the vehicle lamp fault error reporting system can send a signal to the vehiclebody controller after the first level or the second level changes, so that the vehicle body controller can receive a signal representing a vehicle lamp fault when the vehicle lamp is in an open-circuit fault or a short-circuit fault.
本发明提供了一种车灯故障报错系统,包括:车灯模组电路,所述车灯模组电路包括车灯模块、检测模块和信号接口;所述车灯模块包括第一端点和第二端点;所述检测模块能够在所述第一端点的第一电平变化后生成开路报错信号,所述检测模块能够在所述第二端点的第二电平变化后生成短路报错信号,所述检测模块包括用于输出所述开路报错信号和短路报错信号的第三端点;所述信号接口包括第四端点,所述第三端点和所述第四端点连接;车身控制器,所述车身控制器与所述信号接口连接。这种车灯故障报错系统的检测模块能够在第一电平或第二电平变化后向车身控制器发送信号,让车身控制器在车灯处于开路故障和短路故障时均能够收到表示车灯故障的信号。
