摘要
主机厂对整车性能进行摸底,目前主要有三种方式仿真模拟、转鼓台架测试以及实际道路测试。在整车研发过程中,驱动系统是整车动力的来源,是整车动力性能的贡献者,同时也是整车经济性能的能耗集中点;随着国家政府的大力提倡发展新能源汽车,国内市场各主机厂及零部件厂商形成了百家争鸣的良好竞争景象,正如此,新产品的迭代日益频繁,对整车开发周期、成本、性能等把控提出了新的挑战;根据项目车型开发思路,在产策通过市场调研、竞品分析等方式明确市场定位及初步确定整车性能目标,系统工程师通过匹配计算选型合适部件后,将进行仿真模拟验证阶段;仿真模拟则以成本低,效率高、灵活性强、实用性强、周期短,不受场地环境限制等长处,在项目之初,对整车确定动力性及CLTC经济性目标有着重要指导意义,缩短设计周期和设计成本,降低试制成本和试验成本,减少过程资源的浪费;本文将通过在实际项目开展中用Cruise仿真进行模型设计及应用。
At present,there are three main ways for OEMs to conduct a thorough survey of vehicle performance,such as simulation,drum bench test and actual road test.In the process of vehicle research and development,the drive system is the source of vehicle power,the contributor to the power performance of the whole vehicle,and the energy consumption concentration point of the economic performance of the whole vehicle.With the vigorous promotion of the development of new energy vehicles by the national government,the domestic market OEMs and parts manufacturers have formed a good competition scene of hundreds of schools of thought,just as this,the iteration of new products is becoming more and more frequent,which poses new challenges to the control of vehicle development cycle,cost and performance;According to the project model development ideas,after the production strategy clarifies the market positioning and preliminarily determines the vehicle performance target through market research and competitive product analysis,the system engineer will conduct the simulation and verification stage after calculating the selection of suitable components through matching calculation;Simulation has the advantages of low cost,high efficiency,strong flexibility,strong practicability,short cycle,and no site environment restrictions,and at the beginning of the project,it has important guiding significance for determining the power and CLTC economic goals of the whole vehicle,shortening the design cycle and design cost,reducing the trial production cost and test cost,and reducing the waste of process resources;In this paper,the model will be designed and applied by using Cruise simulation in the actual project development.
