摘　　要：为了改善某并联式混合动力SUV汽车的燃油经济性与动力性，运用ADVISOR2002中基于Matlab的多层次参数扫描算法，以燃油经济性为优化目标，以动力性为约束条件，对该车型的多能源控制策略进行优化。最后对控制策略优化前后的SUV性能进行仿真。结果表明，优化后燃油经济性在多种路况下都得到了不同程度提高。For improving the fuel economy and performance of a parallel hybrid electric SUV, an optimiza- tion is conducted on the muhi-energy control strategy for the SUV by using the Matlab-based multi-level parameter sweep algorithm in ADVISOR 2002, with fuel economy as objective and performance as constraint. Finally the performances of SUV with control strategies before and after optimization are simulated and the results show that the fuel economy of SUV after optimization has improved to different extents under different road conditions.
