The invention provides a vehicle-mounted system and a communication method thereof, and the vehicle-mounted system comprises a vehicle-mounted communication unit which is used for obtaining vehicle data and transmitting the vehicle data to other function modules of the vehicle-mounted system; the automatic driving unit is in communication connection with the vehicle-mounted communication unit so as to control the vehicle according to the received vehicle data; wherein the vehicle-mounted communication unit comprises a data receiving and transmitting module and a shared memory module which are in communication connection with each other, and the data receiving and transmitting module and the automatic driving unit perform data access based on the shared memory module so as to realize communication between the vehicle-mounted communication unit and the automatic driving unit. The technical problems to be solved are that the requirement of an automatic driving module for the timeliness of vehicle data is high, an event-driven communication mode is complex, the timeliness of vehicle data transmission is difficult to guarantee, and packet loss illusion is easily caused.

    本申请提供了一种车载系统及其通信方法,车载系统包括:车载通信单元,用于对车辆数据进行获取以及将车辆数据传输至车载系统的其他功能模块;自动驾驶单元,自动驾驶单元与车载通信单元通信连接,以实现根据接收到的车辆数据,从而对车辆进行控制;其中,车载通信单元包括相互通信连接的数据收发模块和共享内存模块,数据收发模块与自动驾驶单元基于共享内存模块进行数据存取,以实现车载通信单元与自动驾驶单元之间的通信。本申请拟解决的技术问题是,自动驾驶模块对车辆数据的时效性要求高,而事件驱动的通信方式较为复杂,难以保证车辆数据传输的时效性,容易造成丢包假象。
