The invention provides an automobile network topology structure and an automobile, all controllers of the whole automobile are integrated in a central controller and three domain controllers, and the domain controllers are distributed on three sides of the central controller and are in communication connection with the central controller through a ring Ethernet. All sensors and actuators of the whole vehicle are distributed to nearby domain controllers to be controlled according to the principle of proximity, and each domain controller controls the sensors and/or actuators within the control range of the domain controller through a CAN bus and/or an LIN bus. The number of vehicle control units is effectively reduced, the centralization degree of domain controller functions and the intelligent safety of a network topology structure are improved, and hardware platformization is conveniently achieved. The bandwidth rate is improved, a traditional network topology structure is simplified, and the problems that traditional wire harness wiring and changing are complex and frequent, and wire harness cost, quality and weight are difficult to control are effectively solved.
本申请提供一种汽车网络拓扑结构及汽车,整车的所有控制器集成于一个中央控制器和三个域控制器中,各域控制器分布于中央控制器的三面,并通过环形以太网与中央控制器通信连接。整车的所有传感器及各执行器按照就近原则分配至就近的域控制器控制,每个域控制器对自身控制范围内的传感器和/或执行器通过CAN总线和/或LIN总线实现控制。有效减少了整车控制器的数量,提高了域控制器功能的集中化程度以及网络拓扑结构的智能安全性,便于实现硬件平台化,并提高了带宽速率并简化了传统网络拓扑结构以及有效解决了传统线束布线和变更复杂又频繁、线束成本和质量以及重量难以控制等问题。
