The invention provides a vehicle communication method and device and a storage medium, and relates to the technical field of vehicle communication, the vehicle communication method and device are applied to an MCU included in an intelligent cabin of a vehicle, the intelligent cabin further comprises an SOC performing signal interaction with the MCU, a target signal sent by an ECU is received, and the target signal carries first communication data; in response to the fact that the first communication data is detected to change relative to second communication data, an incremental communication mode is adopted, a first communication data packet containing a signal identifier of the target signal and the first communication data is generated, and the second communication data is carried in a previous signal sent by the ECU to the MCU; and sending the first communication data packet to the SOC. According to the method and the device, the incremental communication mode is adopted, so that the data interacted between the MCU and the SOC is changed, and the unchanged data does not occupy communication resources any more, so that the utilization rate of a communication bus is improved, and the communication load is reduced.
本申请提供一种车辆通信方法、装置和存储介质,涉及车辆通信技术领域,应用于车辆的智能座舱中包含的MCU,智能座舱内还包含与MCU进行信号交互的SOC,接收ECU发送的目标信号,该目标信号携带第一通信数据;响应检测到第一通信数据相对第二通信数据发生变化,采用增量通信方式,生成包含目标信号的信号标识和第一通信数据的第一通信数据包,其中,第二通信数据携带在ECU向MCU发送的上一信号中;向SOC发送第一通信数据包。本申请通过采用增量通信方式,使得在MCU与SOC之间交互的都是变化的数据,不变的数据不再占用通信资源,从而提高通信总线利用率,进而降低通信负荷。
