基于转矩优化分配的电动汽车横摆稳定性研究
Research on Electric Vehicle Yaw Stability Based on Torque Optimum Distributions
摘要
Abstract
With improving vehicle stability as obj ective,a combination control strategy of yaw rates and slip angles was designed for a four in-wheel-motor driven electric vehicle based on fuzzy con-trol method.A hierarchical control structure was investigated,the upper layer obtained required addi-tional yaw moments based on fuzzy control theory,while lower layer used weighted least squares method to optimize torque distributions by adopting an in-wheel motors/hydraulic brake system com-bined control strategy.And real-time simulation experiments were carried out based on real-time sim-ulation platform,simulation results show that the optimal allocation control strategy of combined in-wheel motor and the hydraulic braking system may improve the stability of vehicles effectively.关键词
