    摘要:

    傳統(tǒng)內(nèi)燃機(jī)汽車牽引力控制系統(tǒng)發(fā)出的控制命令無法直接給混合動力汽車,，需要重新設(shè)計混合動力汽車的牽引力控制系統(tǒng)。提出ISG型混合動力汽車牽引力分層控制體系,，上層控制采用基于動態(tài)滑模的整車期望驅(qū)動總力矩制定策略,；中層控制采用基于低通濾波的發(fā)動機(jī)目標(biāo)轉(zhuǎn)矩設(shè)計算法和基于模型匹配二自由度控制的轉(zhuǎn)矩動態(tài)協(xié)調(diào)控制策略；底層控制采用基于動態(tài)補(bǔ)償?shù)南到y(tǒng)退出策略,。對控制系統(tǒng)進(jìn)行了仿真和硬件在環(huán)試驗驗證,，結(jié)果表明提出的混合動力汽車牽引力控制方法能夠快速、準(zhǔn)確地抑制車輪的過度滑轉(zhuǎn),，有效地實現(xiàn)了ISG型混合動力汽車牽引力控制功能,。

    Abstract:

    Control method for traction control system of conventional internal combustion engine vehicle is not suitable for hybrid electric vehicle. The traction control system of hybrid electric vehicle should be redesigned. Hierarchical traction control system for ISG hybrid electric vehicle was proposed. In the top layer, desired traction total torque calculation strategy was used based on dynamical sliding mode control. In the middle layer, design algorithm of target engine torque based on low pass filtering and dynamic coordinate control strategy based on model matching 2-DOF control were developed. In the bottom layer, exit strategy based on dynamic compensation was proposed. At last, tests of simulation and hardware-in-loop were performed to verify the control system. Results of simulation and test showed that the proposed hierarchical traction control method for ISG hybrid electric vehicle could control the slipped wheels quickly and accurately to realize the traction control function of ISG hybrid electric vehicle effectively. 
