The invention provides an intelligent drive-by-wire chassis system and a decoupling control method. The system comprises a drive-by-wire chassis domain controller, a steer-by-wire system, a drive-by-wire braking system, a drive-by-wire driving system and a drive-by-wire suspension system. Reversibility of the drive-by-wire chassis system is analyzed by using a fuzzy least square support vector machine; a drive-by-wire chassis system inverse system is designed; based on a decoupled drive-by-wire chassis pseudo-linear system, control strategies such as chassis subsystem braking energy recovery,braking force distribution, front and rear axle torque distribution, smoothness and steering stability are designed; and mutual coupling interference among the subsystems is reduced, corresponding decoupling control can be better implemented on the subsystems, and a problem that conflicts are generated due to a fact that control targets of a drive-by-wire chassis execution end are inconsistent issolved.
本发明提供了一种智能线控底盘系统及解耦控制方法,包括线控底盘域控制器、线控转向系统、线控制动系统、线控驱动系统、线控悬架系统,通过利用模糊最小二乘支持向量机分析线控底盘系统可逆性,设计线控底盘系统逆系统,基于解耦后的线控底盘伪线性系统设计底盘子系统制动能量回收、制动力分配、前后轴扭矩分配、平顺性和转向稳定性等控制策略,降低了各子系统之间的相互耦合干扰,有利于更好的对各子系统实施相应的解耦控制,解决了线控底盘执行端控制目标不一致而产生冲突的问题。
