摘要
随着汽车使用的普及,能源消耗和污染物排放已经成为日益严重的问题,降低油耗减少污染物排放是汽车行业必须面临的问题。法规对油耗目标值的要求也越来越严格。建立了整车的参数化模型和控制策略模型,通过对整车参数的灵敏度进行分析,优化整车设计参数和控制参数,找到降低油耗的参数优化方案,使整车油耗满足国家的目标要求。
With the popularization of automobile,energy consumption and pollutants emission have become increasingly serious problems.Reducing fuel consumption of automobile and reducing pollutants emission are the problems that automobile industry must face.Regulations on fuel consumption limits are becoming more and more stringent.The parametric model and control strategy model of the vehicle were established to analyze the sensitivity of vehicle parameters.By optimizing the design parameters and control parameters of the automobile,the methods of reducing fuel consumption were achieved,so the fuel consumption of the whole vehicle meets the requirements of national laws and regulations.
