    摘要:

    針對現(xiàn)行電動汽車再生制動的不足,提出一種新型電磁機械耦合再生制動系統(tǒng)(EMCB),,進行了動力學分析和耦合機理研究;針對目前傳統(tǒng)ABS離散開關控制的不足,,基于EMCB系統(tǒng)和模糊自適應滑模控制提出了一種連續(xù)狀態(tài)控制的ABS控制策略,,以對接路面下的車輛直行制動工況和低附路面下的彎道制動工況為例,,對車輪滑移率、制動能回收率,、制動穩(wěn)定性等進行了仿真分析,。研究結果表明,所提出的ABS控制策略具有良好的響應性,、 魯棒性和滑移率控制性能,,既保證了制動穩(wěn)定性和制動效能,又提高了制動能回收率,,有效增加了電動汽車的續(xù)駛里程,。

    Abstract:

    For the deficiency of current electric vehicle compound regenerative braking, a new design of electromagnetic-mechanical coupled regenerative braking system was proposed (referred to as EMCB), and the coupled mechanism and dynamic model were analyzed. For the deficiency of conventional ABS discrete on-off control, a continuous-state control of anti-lock braking control strategy was proposed based on EMCB system and fuzzy-adaptive sliding mode control for electric vehicle. With Matlab/Simulink the dynamic model of EMCB and controller model were established, and the vehicle model was built by CarSim. With the co-simulation platform of Matlab/Simulink and CarSim, the braking energy recovery, braking stability and braking efficiency were studied and simulated in case of straight braking condition on step adhesive coefficient road and cornering braking condition on low adhesive coefficient road. The results showed that the ABS control strategy had good responsiveness, robustness and slip control performance. Fuzzy-adaptive variable structure control was insensitive to the road conditions and system model and control variable was flat and smooth, it reduced the demand of executive system. The control strategy ensured braking stability and braking efficiency at the limit of adhesion and large angle steering, which can maintain high recovery efficiency and increase the driving range of electric vehicles effectively.
