The invention discloses a vehicle stability test method, a storage medium and a vehicle. The method comprises the steps that in the stability testing process of a vehicle, in response to the situation that the steering wheel rotation angle of the vehicle is larger than a preset rotation angle threshold value and the steering wheel rotation speed of the vehicle is larger than a preset rotation speed threshold value, a side slip angle set and a side slip angle speed set of the vehicle are obtained; constructing an intercept elliptic equation based on a first side slip angle in the side slip angle set and a first side slip angle speed in the side slip angle speed set, and constructing a maximum elliptic equation based on the side slip angle set and the side slip angle speed set; performing similarity fitting on the intercept elliptic equation and the maximum elliptic equation to obtain a fitted elliptic equation; and determining a test result of the vehicle based on the fitting elliptic equation, the test result being used for representing whether the stability of the vehicle meets a preset condition. According to the invention, the technical problem of low vehicle stability test efficiency in the prior art is solved.

    本发明公开了一种车辆的稳定性测试方法、存储介质及车辆。其中,该方法包括:在车辆进行稳定性测试的过程中,响应于车辆的方向盘转角大于预设转角阈值,且车辆的方向盘转速大于预设转速阈值,得到车辆的质心侧偏角集合和质心侧偏角速度集合;基于质心侧偏角集合中的第一质心侧偏角和质心侧偏角速度集合中的第一质心侧偏角速度,构建截距椭圆方程,并基于质心侧偏角集合和质心侧偏角速度集合,构建最大值椭圆方程;对截距椭圆方程和最大值椭圆方程进行相似度拟合,得到拟合椭圆方程;基于拟合椭圆方程确定车辆的测试结果,其中,测试结果用于表示车辆的稳定性是否符合预设条件。本发明解决了相关技术中车辆稳定性测试效率较低的技术问题。
