The invention discloses a miniature new energy automobile network topology architecture, which comprises an automobile body controller BCM and a gateway module GW, and is characterized in that the automobile body controller BCM and the gateway module GW are respectively connected with a P-CAN, a C-CAN, a B-CAN, a diagnosis CAN and an LIN; the P-CAN is a power CAN, and the P-CAN is connected with an MCU (Microprogrammed Control Unit), a BMS (Battery Management System), a CDU (Condition Data Unit) and a gear switch; the C-CAN is a chassis intelligent driving CAN, and an ESC, an EPB, an EPS and an ACU/EDR are connected to the C-CAN; according to the method, four paths of CANs and one path of LIN are planned, and the problem that the network load rate is too high due to the fact that a vehicle body stabilization system (ESC), a front collision warning (FCW), a lane departure warning (LDW), a door opening warning (DOW) and other functions are added is solved. According to the invention, the independent diagnosis CAN is planned, and the technical requirements of the country on the isolation and access authentication of information inside and outside the vehicle and the like of vehicle information safety regulations are met.

    本发明公开了一种微型新能源汽车网络拓扑架构,包括车身控制器BCM和网关模块GW,所述车身控制器BCM和网关模块GW上分别连接有P‑CAN、C‑CAN、B‑CAN、诊断CAN和LIN;所述P‑CAN为动力CAN,所述P‑CAN上连接有MCU、BMS、CDU和怀挡开关;所述C‑CAN为底盘智驾CAN,所述C‑CAN上连接有ESC、EPB、EPS和ACU/EDR;本发明规划了4路CAN和1路LIN,解决了因增加车身稳定系统(ESC)、前碰预警(FCW)、车道偏离预警(LDW)、开门预警(DOW)等功能造成网络负载率过高的问题。本发明规划了独立的诊断CAN,解决了国家对于车辆信息安全法规要求的车内和车外信息隔离与访问认证等技术要求。
