摘要
制造高性能的混合动力电动车的关键是其各个子系统的协调工作,以及各个子系统之间检测参数的共享,因此对各个子系统之间通信的实时性和信息共享性具有较强的要求。本文主要研究基于CAN总线的混合制动能量回馈系统,采用SAE 1939协议,搭建了CAN总线整车控制网络,系统根据工况将总制动力矩按不同比例分配为能量回馈制动、机械制动和ABS制动,实现最优制动。
The coordination work, as well as the sharing of detecting parameters among each regenerative braking system based on CAN Bus is studied, using SAE 1939 Protocol, and the general control network of the vehicle is built based on CAN Bus. In order to achieve optimal braking control, the total braking torque is divided into energy regeneration braking, mechanical breaking and ABS breaking by different proportion, according to the actual condition.
