基于CRUISE的乘用车起停技术性能仿真分析

摘要

Reducing energy and fuel consumption is a hard topic in the eurrent automobile industry. The paper analyzes the principles of start-stop technology and its strategic application in the working condition of NECD, and the paper establishes a simulation model of start-stop system based on the software of CRUISE. Taking a vehicle as an example, the paper introduces the control strategy an（l methods to reducing fuel eonsumption in the matching process of the whole vehicle. The resuhs show thai the start-slop system will improve the fuel economy about 6% for vehicles, and the system can reduce fuel consumption significantly.%减少能源消耗，降低汽车油耗是目前汽车工业面，临的严峻课题。文章通过分析起停技术原理在实际NEDC工况中的策略应用，运用CRUISE性能分析软件建立起动／停止系统仿真模型，并以某车型为例，解释了在整车匹配过程中降低油耗的控制策略及方法。结果表明，起停技术对该车型整车燃油经济性的影响约为6％，证明将起动／停止系统应用在整车上可以很好地降低整车油耗。
