摘　　要：提出了一种用于设计汽车运行工况的新方法,以速度和功率(velocity and power,VP)分布一致性为设计目标,建立满意准则模型进行汽车运行工况设计。在分析处理实车试验数据的基础上,设计开发了长春市乘用车运行工况,并且通过分析设计工况的油耗特性,验证了基于VP分布的运行工况设计方法的合理性。A new method is proposed for the design of vehicle driving cycles, which uses the distribution of velocity and power as the design target, and establishes the satisfaction criterion model for designing driving cycles. Then, the driving cycle of passenger ear in Changchun is designed based on the analysis of the test data. Finally, the rationality of the new method to design the vehicle driving cycles has been verified through analyzing the Fuel Consumption Characteris- tic of the designed cycle.
