The invention discloses a vehicle transverse stability control method based on a heuristic algorithm. The method comprises the following steps: parameters of a vehicle are collected, wherein the parameters needing to be collected comprise intrinsic parameters and real-time parameters, and the intrinsic parameters comprise the total mass m of the vehicle, the rotational inertia Iz, the distances lfand lr from a front axle and a rear axle to the gravity center of the vehicle, and the cornering stiffnesses Cf and Cr of a front wheel and a rear wheel, and the parameters are inherent to the vehicle and can be collected and stored in advance. The heuristic algorithm is adopted to solve the output feedback controller, so that complex iteration in a traditional solving method is avoided; the longitudinal speed of the vehicle and the cornering stiffness of the tire are considered as uncertain parameters; the controller designed by the invention is better in robustness, can calculate an appropriate yawing moment, controls the side slip angle and the yawing angular velocity to be within an appropriate range, improves the maneuverability of an vehicle, improves the transverse stability of thevehicle, and reduces the possibility of dangerous situations in the operation process of the vehicle.

    本发明公开了一种基于启发式算法的车辆横向稳定性控制方法,包括下述步骤:采集汽车的参数;需要采集的参数包括固有参数和实时参数,其中:固有参数:包括汽车总质量m,转动惯量I,前、后轴到汽车重心的距离l、l,以及前、后轮的侧偏刚度C、C;这些参数是汽车固有的,可提前采集并存储;本发明采用启发式算法来求解输出反馈控制器,避免了传统求解方法中的复杂迭代;考虑汽车纵向速度和轮胎侧偏刚度为不确定参数,本发明所设计的控制器鲁棒性更好,能够计算出合适的横摆力矩,控制质心侧偏角和横摆角速度在一个合适的范围内,提高汽车的操纵性能,改善汽车的横向稳定性能,降低汽车运行过程中发生危险情况的可能。
