摘　　要：为降低某微型客车的油耗,对其动力传动系统参数的优化设计和匹配问题进行了分析。利用仿真软件AVL-Cruise建立了整车性能仿真模型,并集成到优化平台iSIGHT软件中,对计算模型进行标定。通过两个软件的集成,对汽车动力传动系统的速比参数进行了优化设计和匹配。结果表明,在满足汽车动力性设计指标的前提下,优化后车辆NEDC工况的油耗降低了0.53L/100km,满足了预期设计要求。In order to reduce fuel consumption of a mini bus,analyzed optimization design and match question of powertrain parameters.Applying simulation software AVL-Cruise to establish simulation model of the complete vehicle performance,integrate with iSIGHT software,and calibrate the calculation model.Based on the integration of the two software,optimized and matched the gear ratio of vehicle powertrain.The results show that fuel consumption of NEDC working condition reduced 0.53 L/100 km and satisfied design requirement,at the same time,the vehicle dynamic performance target is also fulfilled.
