The invention discloses a distributed electric vehicle stability control method based on a stability domain, and relates to the field of vehicle auxiliary driving. Combined control over the yaw velocity and the side slip angle is achieved, the target longitudinal force and the target yaw moment of the vehicle are obtained respectively, the weight P of a controller is distributed through a stability domain, the weighted yaw moment is obtained, distribution of the additional yaw moment is achieved according to the vertical load dynamic change of wheels, and therefore vehicle stability control is improved. The stability control strategy can obviously improve the operation stability of the vehicle, has many obvious beneficial effects compared with the prior art, and overcomes the defect that the vehicle stability control effect is poor in the prior art.
本发明公开了一种基于稳定域的分布式电动汽车稳定性控制方法,涉及汽车辅助驾驶领域。实现对横摆角速度和质心侧偏角的联合控制,分别获取车辆目标纵向力和目标横摆力矩,利用稳定域分配控制器权重P,得到加权横摆力矩,按照车轮的垂向载荷动态变化实现附加横摆力矩的分配,以此提高车辆稳定性控制。该稳定性控制策略能够明显提高车辆的操纵稳定性,相对现有技术具有非常显而易见的诸多有益效果,解决了现有技术对车辆稳定性控制效果差的缺陷。
