基于SAEJ1939的混合动力客车ABS控制系统

ABS Control System of Hybrid Electric Vehicle Based on the SAE J1939 Protocol

研究了混合动力客车的制动过程和能量回收原理,提出在刹车防抱死系统(ABS)参与制动时,混合动力客车制动控制策略和能量回收的实现。依据SAE J1939通讯协议的具体内容,制定了ABS控制系统通讯的数据报文格式,实现了ABS控制器与整车控制器(HECU)之间的数据交流与共享。

The paper researches the energy recycle principle and braking course of hybrid electric vehicle,and then puts forward the braking control strategy and the realization of the energy recycle of hybrid electric vehicle at the condition of ABS system participate in the braking.According the detail content of SAE J1939 protocol,the massage format of communication in ABS control system is designed,which realizes the ABS controller share and communication data with the HECU（High Electronic Control Unit）.
