摘要

以某纯电动轻卡为研究对象,在保持动力传动系统方案不变的前提下,优化整车控制,提出续始里程优化方案。基于CRUISE-MATLAB联合仿真平台搭建整车模型,对各优化方案进行仿真分析。结果表明:在不过度影响车辆驾驶感受的前提下,通过电机制动扭矩优化、及电机功率衰减可以有效的延长车辆的续驶里程,其中电机制动扭矩优化效果较为显著。综合优化方案可以提升28km续驶里程,提高了产品的市场竞争力。
        An electric truck was taken as the research object, optimization control programs were put forward to extend vehicle driving range, in the condition of maintaining current powertrain system. Each program was simulated and computed based on CRUISE-MATLAB co-simulation platform. The results indicate that electric machine braking torque optimization、accelerator pedal position signal optimization and electric machine power attenuation can effectively extend the driving range of the vehicle, and electric machine braking torque optimization is the most significant scheme. The comprehensive optimization scheme can increase 28 km driving range, which improves vehicle competitiveness.
