The invention discloses an intelligent vehicle stability control method considering a preview angle and time delay compensation, which comprises the following steps: S1, considering the maneuverability, the transverse stability and the roll stability of a vehicle, and constructing a vehicle stability control model; and S2, adjusting each parameter value in the vehicle stability control model to enable the vehicle stability control model to obtain a minimum value, taking a control variable set when the vehicle stability control model obtains the minimum value as an optimal control parameter, and enabling the optimal control parameter to act on the vehicle through time lag. According to the method, the preview information and the time lag of the drive-by-wire execution mechanism can be fully considered, so that the trajectory tracking performance, the transverse stability and the roll stability of the vehicle under various working conditions are improved.

    本发明公开了一种考虑预瞄转角和时滞补偿的智能车辆稳定性控制方法,包括:S1.考虑车辆的机动性、横向稳定性和侧倾稳定性,构建车辆稳定性控制模型;S2.调整车辆稳定性控制模型中各参数值,使得车辆稳定性控制模型取得最小值,将车辆稳定性控制模型取得最小值时设置的控制变量作为优化控制参数,经过时滞后将优化控制参数作用于车辆。本发明能够充分考虑预瞄信息和线控执行机构时滞,以提高车辆在各种工况下的轨迹跟踪性能、横向稳定性和侧倾稳定性。
