The invention discloses a whole vehicle dynamic performance control method and system based on road adhesion coefficient recognition, and provides a global control strategy capable of improving transverse and longitudinal dynamic performance of a whole vehicle by comprehensively considering a cooperative work mechanism of subsystems of the vehicle and a transverse and longitudinal coupling influence mechanism of vehicle dynamics aiming at a traditional power four-wheel drive vehicle. A modern control theory and vehicle dynamics are combined, an agile dynamics control method is used, agility, smoothness and control stability of the whole vehicle in a curve under different road surfaces are improved, and a driving experience of a driver is improved. Compared with the prior art, the method and the system have the advantages that whole vehicle steering response of a daily use condition of a user can be improved; safety, driving stability and turning smoothness of the vehicle are improved;meanwhile, the method and the system can be used for optimizing an automatic driving vehicle control technology by referring to the field of automatic driving vehicle control, and particularly can beused for coupling control in the curve.

    基于路面附着系数识别的整车动态性能控制方法及系统,其针对传统动力四轮驱动车辆,综合考虑了车辆各子系统的协同工作机制以及车辆动力学的横纵向耦合影响机制,提出了可改善整车横纵向动力学性能的全局控制策略。其结合现代控制理论、车辆动力学,用一种敏捷动力学控制方法,改善了不同路面下整车在弯道中的敏捷性、平顺性和操纵稳定性,提高驾驶员的驾乘体验。相对于现有技术,可改善用户日常使用工况的整车转向响应,提高车辆的安全性、行驶稳定性及过弯平顺性,同时还能够借鉴于自动驾驶车辆控制领域,用于对自动驾驶车辆控制技术的优化,尤其可用于弯道中的耦合控制。
