摘　　要：线控转向与主动防倾杆均有助于提高车辆行驶的主动安全性,为更好发挥这2个子系统的功能,对线控转向与主动防倾杆进行协同控制研究。由于车辆结构具有复杂性和模型参数的不确定性,协同控制采用模糊控制器实现,经过模糊控制可以得到车辆的附加前轮转角和前后主动防倾杆的力矩分配系数,以此实现对线控转向和主动防倾杆的协同控制。为证明协同控制的有效性,进行阶跃工况试验和双移线工况试验的仿真验证。仿真结果表明,经过协同控制的车辆与未协同控制的车辆相比,可以有效改善车辆的操纵稳定性和行驶安全性。Both steering-by-wire and active anti-roll bar are helpful to improve the active safety of vehicle driving.In order to give better play to the functions of these two subsystems,the cooperative control of steering-by-wire and active anti-roll bar is studied.Because of the complexity of vehicle structure and the uncertainty of model parameters,the cooperative control is realized by fuzzy controller.Through fuzzy control,the additional front wheel angle and the moment distribution coefficient of front and rear active antiroll bar can be obtained,so as to realize the cooperative control of the linear steering and active anti-roll bar.In order to prove the effectiveness of the cooperative control,the step condition test and the double shift condition test are simulated and verified.The simulation results show that the vehicle with cooperative control can effectively improve the vehicle handling stability and driving safety compared with the vehicle without cooperative control.
