The invention discloses a data transmission method, a dual-SOC vehicle-mounted system and a vehicle machine. Mutual takeover and safety redundancy design of multiple communication modes are achieved between the two SOCs, when one SOC breaks down, the other SOC can be used for achieving data processing, or when one communication mode breaks down, other communication modes can be used for achieving data transmission, and the two SOCs can further add a transmission indication field in a data packet, so that the data transmission efficiency is improved. The transmission indication field is used for endowing the transmission priority for shunting, and the data is transmitted in sequence, so that the problem that the data cannot be processed and transmitted in time due to the fault of a certain SOC or the abnormality of a certain communication link is avoided. And the stability and the reliability of the system are improved through the safety redundancy design.

    本申请公开了一种数据传输方法、双SOC车载系统及车机。通过在双SOC之间实现互相接管和多种通信方式安全冗余设计,当其中一个SOC故障时可以使用另一个SOC实现数据处理,或一种通信方式出现故障时使用其他通信方式实现数据传输,并且双SOC还可以在数据包中增加传输指示字段,以传输指示字段赋予传输优先级进行分流,按序传输,因此避免了由于某一个SOC故障或某一个通信链路异常导致数据无法及时处理和传输的问题。通过安全冗余设计提高了系统的稳定性和可靠性。
