| 摘 要： | 介绍了采用继电器对发动机管理系统ECU的工作进行控制,同时针对发动机管理系统原有的减速断油模式进行了重新标定,实现了发动机高转速起动功能,且降低了停机时的转速,避免了对发动机ECU频繁的通/断电操作及因频繁起动造成的发动机燃油消耗率和排放性能的不良影响。

| Abstract: | In the paper,the engine start and stop operations of hybrid electric vehicle can improve fuel economy and emission performance. Through engine start control and recalibration of deceleration fuel cutoff(DFCO) mode,engine start is achieved at higher speed,DFCO operation zone is enlarged,engine speed is reduced when engine stops,and turn on / off engine ECU frequently is avoided,engine fuel economy and emission will be improved. |
