摘要
前向式仿真模型在车辆设计过程中不可缺少,考虑到当前混合动力SUV发展快速,以Advisor软件为基础,通过二次开发建立四驱型混合动力汽车前向仿真模型。模型的主控模块中包含驾驶员模型,驾驶员模型中包含PI控制模块、车辆需求纵向作用力预估模块,并且主控模块集成了制动力分配策略和能量分配策略,以此简化顶层模型。四驱车轮模块考虑了驱动防滑及纵向作用力前后合理分配的基本原理,从而较好地模拟扭距分配。针对某款混合动力SUV用此四驱前向仿真模型进行模拟工况分析。仿真结果表明:模型的有效性,可以用于前向性仿真分析。
Facing-forward simulation model is necessary during the process of vehicle design,in considering of the rapid development of hybrid SUV,in the paper,a facing-forward simulation model for 4WD（ 4 wheel drive） hybrid vehicle is established by secondary development of the Advisor software. The main control module of the simulation model includes a driver model,which contains a PI control module and the demand prediction module of vehicle longitudinal force. The braking force distribution strategy and energy distribution strategy are also integrated into the main control module to simplify the top model. Basic theory of ASR（ Acceleration Slip Regulation） and reasonable distribution of longitudinal force between front wheel and rear wheel are considered in the 4WD wheel module to simulate torque distribution. The established facing-forward 4WD simulation model is applied in the analysis of a hybrid SUV with a virtual working condition,the result shows the established model is valid in facing-forward simulation.
