The invention provides a signal transmission method and a vehicle-mounted Ethernet system, which can reduce cost and system power consumption while realizing long-distance high-speed signal transmission. The signal transmission method is applied to a vehicle-mounted Ethernet system and comprises the steps that a vehicle-mounted gateway sends a signal in a first digital coding format to a first connector, and the vehicle-mounted gateway and the first connector are connected through a digital interface; the first connector receives the signal in the first digital coding format, converts the signal in the first digital coding format into a signal in a pulse amplitude modulation (PAM) format, and sends the signal in the PAM format.

    本申请提供了一种信号传输方法和车载以太网系统,能够在实现远距离高速信号传输的同时,降低成本,减少系统功耗。该信号传输方法应用于车载以太网系统,包括:车载网关向第一连接器发送第一数字编码格式的信号,所述车载网关和所述第一连接器之间通过数字接口连接;所述第一连接器接收所述第一数字编码格式的信号,并将所述第一数字编码格式的信号转换为脉冲振幅调制PAM格式的信号,发送所述PAM格式的信号。
