The invention provides a method and device for restraining vehicle jerking, a vehicle and a storage medium, and belongs to the field of energy recuption.The method comprises the steps that under the condition that the running working condition of the vehicle represents that the vehicle is currently in a target deceleration working condition, the motor torque of the vehicle and the suspension height of at least one wheel are obtained; predicting a switching time for switching from the electric brake to the hydraulic brake in the event that the suspension height of at least one wheel changes; on the basis of electric braking force generated by electric braking rising, wheel end pressure corresponding to front wheels and rear wheels of the vehicle when the switching time arrives is determined; and adjusting the damping of the suspension based on the wheel end pressure so as to suppress generation of the vehicle pause when the switching time arrives. By means of the method, the pause phenomenon of the vehicle in the switching process from electric braking to hydraulic braking is effectively restrained, and the stability and driving comfort of the vehicle are improved.

    本发明提供了一种抑制车辆顿挫的方法、装置、车辆及存储介质,属于能量回收领域,所述方法包括:在车辆的行驶工况表征所述车辆当前处于目标减速工况的情况下,获取所述车辆的电机扭矩与至少一个车轮的悬架高度;在至少一个车轮的悬架高度发生变化的情况下,预测由所述电制动切换到所述液压制动的切换时间;基于所述电制动上升产生的电制动力,确定在所述切换时间到来时,所述车辆前轮与后轮各自对应的轮端压力;基于所述轮端压力,对所述悬架的阻尼进行调节,以在所述切换时间到来时,抑制所述车辆顿挫的产生。通过本发明提供的方法,有效地抑制电制动向液压制动的切换过程中车辆的顿挫现象,提高车辆的稳定性和驾驶舒适性。
