The invention discloses a vehicle stability determination method and device, a vehicle and a storage medium. The method comprises the steps of obtaining a current control parameter combination and a current state parameter of a target vehicle; a target convergence domain corresponding to the current control parameter combination is determined based on a preset corresponding relation between the control parameter combination and a vehicle convergence domain, the vehicle convergence domain is obtained through trajectory clustering of a three-dimensional phase plane, and the vehicle convergence domain comprises a set of state parameters of the target vehicle in a stable state; and if the current state parameter is located in the target convergence domain, determining that the target vehicle is in a stable state, and calculating a target stability index of the target vehicle. The scheme can improve the accuracy of the vehicle stability result.

    本发明公开了一种车辆稳定性确定方法、装置、车辆及存储介质,所述方法包括:获取目标车辆的当前控制参数组合以及当前状态参数;基于控制参数组合与车辆收敛域之间的预设对应关系,确定所述当前控制参数组合对应的目标收敛域,其中,所述车辆收敛域通过三维相平面的轨迹聚类得到,且所述车辆收敛域包括所述目标车辆处于稳定状态下的状态参数的集合;若所述当前状态参数位于所述目标收敛域,确定所述目标车辆处于稳定状态,并计算所述目标车辆的目标稳定性指标。本方案能够提高车辆稳定性结果的准确性。
