本文研究了并联式混合动力汽车(HEV)的行驶性能。标准的等效消耗最小化策略(ECMS)已被修改为考虑驾驶性能指标，而没有导致次最优解的后验修正。结果表明，对于这类车辆，在燃油经济性和驾驶性能之间进行权衡是可能的：以本文所考虑的应用为例，在燃油消耗仅增加1%的情况下，驾驶性能指标可提高2倍。利用离线工具求出了最优控制问题的解，并通过静态映射得到了在线实现。
In this paper the drivability of a parallel hybrid electric vehicle (HEV) is investigated. The standard Equivalent Consumption Minimization Strategy (ECMS) has been adapted to take into account drivability performance indexes without a posteriori corrections that lead to suboptimal solutions. It can be shown that, for this class of vehicle, a trade off between fuel economy and drivability is possible: in the case of the application considered in this paper, for example, the performance indexes of drivability can be improved by a factor 2 while the fuel consumption increases by only 1%. The solution of the reformulated optimal control problem has been developed with offline tools and then an online implementation through static maps has been derived.
