    • An improved vehicle communications interface (VCI) is both economical and readily adaptable for running new software. The improved VCI includes a server coupled to a bank of processors. The server can communicate with a host, and the processors can communicate with different vehicle networks. Each processor includes a state machine and a media access controller for a particular vehicle network. The state machine identifies incoming messages that require real time responses and provides the requisite responses directly back to the network, without involvement of the server. Real time requirements of the server are thus relieved, allowing the server to run a non-real time, mainstream operating system for which new product software is readily available.
    • 改进的车辆通信接口(VCI)既经济又易于适应于运行新的软件。 改进的VCI包括耦合到一组处理器的服务器。 服务器可以与主机通信,并且处理器可以与不同的车辆网络进行通信。 每个处理器包括用于特定车辆网络的状态机和媒体访问控制器。 状态机识别需要实时响应的传入消息,并将必要的响应直接提供给网络,而不需要服务器的参与。 因此,服务器的实时要求得到了缓解,使服务器能够运行一个非实时的主流操作系统,为新产品软件提供便利。
