The invention relates to an electric vehicle network architecture system and a vehicle with the same, the electric vehicle network architecture system comprises CAN1, CAN2, CAN3 and CAN4 network segments, each network segment is connected through a gateway, the CAN1 network segment is connected with a battery management unit, a vehicle-mounted charger, a motor control unit, an engine control unit and an AC/DC converter unit, the CAN2 network segment is connected with a transmission, and the transmission is connected with a vehicle-mounted charger. The CAN3 network segment is connected with a brake system control unit and a suspension control unit, the CAN4 network segment is connected with an air-conditioning system control unit and a vehicle body control unit, the whole vehicle control unit and the transmission control unit interact with each other and are simultaneously connected to the CAN1 network segment and the CAN2 network segment, and the whole vehicle control unit interacts with the control unit connected with the CAN1 network segment and the transmission connected with the CAN2 network segment. The whole vehicle control unit further interacts with the control unit connected with the CAN3 network segment and the CAN4 network segment through a gateway, the whole vehicle control unit and the transmission control unit are connected to the CNA1 network segment and the CAN2 network segment in a bridging mode at the same time, and the load of a CAN bus is reduced by shunting signals.
本发明涉及一种电动汽车网络架构系统及具有其的车辆,包括CAN1、CAN2、CAN3和CAN4网段,每个网段均通过网关连接,CAN1网段连接有电池管理单元、车载充电机、电机控制单元、发动机控制单元和交直流转换机单元,CAN2网段连接有变速器,CAN3网段连接有制动系统控制单元和悬架控制单元,CAN4网段连接有空调系统控制单元和车身控制单元,还包括整车控制单元和变速器控制单元,二者相互交互同时连接在CAN1和CAN2网段,整车控制单元与CAN1网段连接的控制单元和CAN2网段连接的变速器交互,整车控制单元还通过网关与CAN3和CAN4网段连接的控制单元交互,将整车控制单元和变速器控制单元同时桥接在CNA1和CAN2网段,通过对信号进行分流降低CAN总线的负载。
