The invention relates to a multi-redundancy electronic and electric appliance framework suitable for a pure electric intelligent driving commercial vehicle, which is characterized in that a gateway is used as a main body of bus data exchange, controllers related to vehicle power are independently networked through function division of a sub-network, and the bus communication rate is improved. Through the establishment of each sub-network and the improvement of the communication rate of the power CAN and the information CAN to 500 kbit/s, the bus load rate of the whole vehicle can be effectively reduced, and faults such as network communication interruption, delay or frame loss can be avoided. Meanwhile, when the core node VDCU breaks down or is powered down, the automatic driving controller (ADU) can still perform network communication with other nodes through the gateway (GW), so that the intelligent driving vehicle can still support the vehicle to be out of danger when part of fault points occur. The purpose of improving the vehicle driving safety and the reliability of an electrical system can be achieved.

    本发明涉及一种适用于纯电智能驾驶商用车的多冗余电子电器架构,使用网关做为总线数据交换的主体,通过子网络的功能划分,将整车动力相关的控制器单独组网,并对总线通信速率进行了提升。通过各子网络的搭建及提升动力CAN和信息CAN的通信速率到500kbit/s,可以有效的降低整车总线负载率,避免网络通信中断、延迟或丢帧等故障。同时在核心节点VDCU发生故障或掉电时,自动驾驶控制器(ADU)仍可以通过网关(GW)与其他节点进行网络通讯,使智能驾驶车辆在出现部分故障点时仍可支撑车辆脱离危险。本发明可以达到提升车辆行车安全和电器系统可靠性的目的。
