A method of communicating between a plurality of modules on a vehicle, each module configured as a publisher or subscriber node that communicate in the operation of the autonomous vehicle utilizing a shared memory communication system. The method may include generating groups of messages by publisher nodes, each group associated with a unique topic and generated by a single publisher node associated with the unique topic, writing a group of messages in a message buffer associated with a single topic, writing in a registry, location information indicating where the messages were written, reading new message information from the registry, the new message information indicative of whether a new message associated with a particular topic is available, reading location information indicating where the new message is stored if a new message is available, and reading the new message from the respective message buffer.
一种车辆上多个模块之间进行通信的方法,每个模块被配置为利用共享存储器通信系统在操作自动驾驶车辆时进行通信的发布者节点或订阅者节点。该方法可以包括由发布者节点生成多组消息,每一组与唯一主题相关联并且由与所述唯一主题相关联的单个发布者节点生成,在与所述唯一主题相关联的消息缓存器中写入一组消息,在注册表中写入这些消息被写入的位置的位置信息,从该注册表读取新消息信息,所述新消息信息指示是否有与特定主题相关联的新消息可用,如果有新消息可用,则读取指示存储该新消息的位置的位置信息,并且从相应的消息缓存器中读取该新消息。
