The invention relates to an in-vehicle communication system, an in-vehicle device, and an interface device. An in-vehicle device (2) provided with a function of detecting an abnormality in an in-vehicle system is connected to an interface device (3) including an LED (10) for notifying an occupant of a vehicle of an abnormal state via a communication path (4) for transmitting an AC signal. The cathode of the LED (10) is connected to the body ground of the vehicle, and the anode is connected to the communication line of the communication path (4) via the inductor (13). When the in-vehicle device (2) detects an abnormality in the in-vehicle system, the in-vehicle device (2) applies a DC drive signal to the communication line to drive the LED (10) to notify an occupant of the vehicle of the abnormality.
本发明涉及车载通信系统、车载用装置以及接口装置。具备检测车载系统的异常的功能的车载用装置(2)与包含向车辆的乘客通知异常状态的LED(10)的接口装置(3)经由传输交流信号的通信路(4)连接。使LED(10)的阴极与车辆的车身接地连接,使阳极经由电感器(13)与通信路(4)的通信线连接。车载用装置(2)在检测到车载系统的异常时,通过对通信线施加直流的驱动信号来驱动LED(10)对车辆的乘客通知异常。
