The invention discloses a whole vehicle communication system of an unmanned vehicle and the unmanned vehicle in the technical field of unmanned vehicles, the whole vehicle communication system of the unmanned vehicle comprises a central whole vehicle controller, and the central whole vehicle controller is in communication connection with a vehicle-mounted sensor, a power system and a suspension control system through a CAN bus; and the central vehicle control unit is in communication connection with a motor controller for driving the unmanned vehicle to walk through a FlexRay bus. According to the unmanned platform vehicle communication system based on the CAN-FlexRay double buses, the problem that when a single CAN bus is adopted by an unmanned vehicle, the real-time performance of a network is poor when data are generated at the same time by multiple nodes is solved; the technical problems that when a plurality of CAN buses are adopted for network layout and construction, the network architecture structure is complex, and the requirement of a control system cannot be met are solved, and the system has the advantages of being good in universality, simple in structure, low in cost, easy to achieve and capable of effectively avoiding potential safety hazards and improving the communication reliability of the whole unmanned vehicle system.
本发明公开了无人车技术领域的一种无人车整车通信系统及无人车,无人车整车通信系统包括中央整车控制器,所述中央整车控制器通过CAN总线分别与车载传感器、动力系统和悬挂控制系统通信连接;所述中央整车控制器通过FlexRay总线与用于驱动无人车行走的电机控制器通信连接。本发明实现了一种基于CAN‑FlexRay双总线的无人化平台整车通信系统,避免了无人车采用单一CAN总线,当多个节点同时发生数据时,网络实时性较差的问题;解决了采用多条CAN总线进行网络布局和搭建时,网络架构结构复杂,不能确保满足控制系统的要求的技术问题,具有较好的通用性,结构简单、成本低、易于实现,能有效的避免安全隐患,提高无人车整车系统的通信可靠性。
