本文对铰接式车辆的主动侧倾控制进行了研究。其目标是最大限度地减少横向荷载转移使用抗侧倾杆结合低带宽液压执行机构。在铰接式车辆上执行的操纵试验的结果被用于验证车辆的非线性偏航/横摇模型。采用简化的线性铰接式车辆模型，建立了装有主动减摇杆的车辆横向加速度控制器的设计方法。研究了有源器件的硬件限制和功耗要求。然后将该控制器应用于已验证的铰接式车辆模型，以评估装有主动减摇杆的铰接式货车的性能。仿真结果表明，使用相对较低的功率系统(10kW)、低带宽的致动器(5赫兹)，可以显著改善车辆的瞬时侧倾性能。
SUMMARY This paper describes an investigation into active roll control of articulated vehicles. The objective is to minimise lateral load transfer using anti-roll bars incorporating low bandwidth hydraulic actuators. Results from handling tests performed on an articulated vehicle are used to validate a nonlinear yaw/roll model of the vehicle. The methodology used to design lateral acceleration controllers for vehicles equipped with active anti-roll bars is developed using a simplified linear articulated vehicle model. The hardware limitations and power consumption requirements of the active elements are studied. The controller is then implemented in the validated articulated vehicle model to evaluate the performance of an articulated lorry with active anti-roll bars. The simulation results demonstrate the possibility of a significant improvement in transient roll performance of the vehicle, using a relatively low power system (10 kW), with low bandwidth actuators (5 Hz).
