摘要: 针对车辆在侧向加速度或路面不平干扰时,易发生侧翻的特点,采用了主动横向稳定杆装置。为控制车辆的侧翻并保证车辆的舒适性,利用线性二次型最优控制理论设计了控制器,并采用微粒群优化算法对控制器的权系数进行优化。由于采用AARB控制车辆侧翻时,存在车辆失稳的特点,通过采用ESP装置及设计模糊控制器对带有AARB车辆的失稳进行控制,并进行了仿真试验。仿真结果表明,该集成控制能有效控制车辆的侧翻与失稳,有效提高了车辆的行驶安全性。Abstract: When interfered by the lateral acceleration or uneven road surface, the vehicle was prone to rollover. In this paper, the active anti-roll bar was adopted and the vehicle dynamic model with six degrees of freedom was established for rollover prevention. In order to prevent the rollover and ensure the comfortable riding of vehicle, the linear quadratic (LQ) optimal controller was designed and the weights of the controller were optimized by particle swarm optimization algorithm. However, this approach has a drawback in the loss of maneuverability because the active anti-roll bar for rollover prevention produces instability in vehicle. To overcome this drawback of the active anti-roll bar based method, ESP is designed. Furthermore, this paper carried out a series of simulation experiments which tested the validity of the proposed control strategy in maintaining yaw and roll stability of the vehicle. Simulation results showed that the integrated control method is effective in preventing the rollover and instability of the vehicle.
