摘要
为提升多轴重载车辆在高速极限侧翻工况下的主动抗侧翻性能,以分布式电驱动多轴重载车辆为对象,开发了一种基于转矩分配的多轴重载车辆主动抗侧翻控制方法。该方法以横向载荷转移率为侧倾判据,采用提出的抗抖振模糊-滑模控制算法获得控制所需的期望附加横摆力矩,通过合理分配全轮驱动扭矩产生差动横摆力矩以保证车辆的侧倾稳定,并通过驾驶员在环仿真实验验证了所提出方法的有效性。结果表明:在驾驶员手动操作的极限工况下,所提出控制方法能成功避免车辆发生侧翻,车辆横向载荷转移率最大绝对值降低约2%,车身侧倾角最大值降低约4.9%,横向载荷转移率超侧倾阈值时长降低42.2%。
A multi-axle heavy-duty vehicle active anti rollover control system based on torque distribution was developed to improve the active anti rollover performance of multi-axle heavy-duty vehicles under high-speed extreme rollover conditions,taking the distributed electric drive multi axle heavy-duty vehicle as the object.The lateral load transfer rate was used as the roll criterion,and an Anti-Chattering Fuzzy Sliding Mode Control algorithm was proposed to obtain the desired additional yaw moment,and the differential yaw moment was generated by reasonably distributing all wheel drive torque to ensure the roll stability of the vehicle.And the effectiveness of the proposed method was verified by driver in the loop experiment.The results show that the proposed control method can successfully avoid vehicle rollover under the extreme condition of driver manual operation,and the maximum absolute value of vehicle lateral load transfer rate is reduced by about 2%,the maximum roll angle is reduced by about 4.9%,the time of lateral load transfer rate exceeding roll threshold decreases by 42.2%.
