基于AMESim与MATLAB的混合动力汽车联合仿真平台设计

Design of Hybrid Electric Vehicle Co-simulation Platform Based on AMESim and MATLAB

针对一款搭载新型复合功率分流式动力系统的混合动力汽车基于AMESim和MATLAB设计了联合仿真平台。其中,整车物理模型在AMESim中实现,包括整车基本参数,发动机、电机、变速箱和动力学模型;逻辑控制模块在MATLAB中实现,包括电机与发动机转矩、锁止器与离合器和挡位控制信息。该仿真平台在WLTC和NEDC工况下进行验证,结果显示WLTC工况下油耗6.76L/100km,电耗0.1661kW·h,NEDC工况下油耗5.2L/100km,电耗0.1342kW·h。

A co-simulation platform based on AMESim and MATLAB is designed for a hybrid electric vehicle with a new hybrid power split system.The physical model of the vehicle is realized in AMESim,including the basic parameters of the vehicle,engine,motor,gearbox and dynamics model;the logic control module is realized in MATLAB,including motor and engine torque,lock and clutch and gear control information.The simulation platform is verified under WLTC and NEDC conditions.The results show that the fuel consumption is 6.76 L/100 km and the power consumption is 0.1661 kW·h under WLTC condition,and 5.2 L/100 km and 0.1342 kW·h under NEDC condition.
