An automobile becomes a life necessity of people, internal control communication of an existing automobile depends on a CAN bus, and the building cost and the maintenance cost of the automobile are high. In-vehicle entertainment communication expects'star flash ', and external communication depends on a mobile network. In addition, along with the urgent need of intelligent upgrading of urban traffic management, interactive communication between automobiles and various road facilities becomes more and more important. According to the invention, independent narrowband wireless communication systems which are respectively used for two different passing environments inside and outside the vehicle and have different frequencies are introduced outside an existing mobile network and a star flash system, so that the problem of communication between vehicles, between vehicles and people and between the vehicles and people and the outside when the vehicles enter an area without network signal coverage is solved; and the high-frequency wireless system gradually replaces a CAN bus connection mode, so that the construction and maintenance cost of the automobile is greatly reduced, the interaction capability between the automobile and road traffic facilities is greatly enhanced, and help is provided for unmanned driving.

    汽车已成为人们生活必需品,现有汽车内部控制通信依赖CAN总线,其建造和维修成本都很高;车内娱乐通信则期盼“星闪”,对外通信则依赖移动网络。除此之外,随着城市交通管理智能化升级的急迫需要,汽车与各种道路设施的互动通信也变得越来越重要。本发明在现有移动网络和“星闪”系统之外,引进了分别用于车内和车外两种不同通行环境不同频率的独立窄带无线通信系统,既解决汽车进入无网络信号覆盖区时,车与车、车与人之间,以及他们与外界的通信联系问题,而且其中的高频无线系统将逐步取代CAN总线连接方式,这不仅将大大降低汽车的建造维修成本,而且还将大大加强车辆与道路交通设施之间的互动能力,为无人驾驶提供了帮助。
