混合动力汽车整车控制策略比较分析

Control Strategy Comparison and Analysis for Hybrid Vehicle

对于串联式、并联式和混联式三种混合动力系统的常用结构配置特点和应用分别进行了阐述和分析,重点对三类混合动力系统中实际常用的整车控制策略进行了分析。可以得出混合动力系统越复杂整车控制策略也就越复杂,并从整车性能、开发成本等方面比较和分析各自的优缺点,从而总结出各种控制策略的适用范围和场合。

General configurations and applications of hybrid vehicles in series, parallel and combination of both are presented and analyzed. Focus is on the analysis of vehicle control strategies adopted by these three hybrid systems. The result of the analysis shows that the more hybrid powertrain is complex, the more control strategy is complicated. Then the merits and demerits of vehicle control strategies are compared and analyzed in terms of vehicle performances and costs, from which the application scopes and conditions of various vehicle control strategies are produced.
