基于CAN总线的混合动力汽车控制系统

Development of a CAN Bus Based Control System for Hybrid Electric Vehicle

介绍了基于 CAN总线开发的混合动力汽车控制系统及各子系统的任务、网络图和部分信息流。为了解决整车控制的实时性与汽车车身网络控制系统数据传输量大的矛盾 ,系统采用了高、低速双 CAN总线结构 ,并且通过信息交换模块实现对高、低速 CAN网络中的部分需交换信息的数据交换。

This paper developed a CAN bus based control system for a hybrid electric vehicle (HEV), as well as its task, network figure and partial information streams of the subsystems. To solve the conflict between the real time control of the whole vehicle and the transmission of a huge amount of data in network control system of vehicle body, both high and low speed CAN buses were used in the work system. Some information that needed to be exchanged in the network was exchanged by an information exchange module.
