The invention discloses a vehicle side slip angle calculation method and device, electronic equipment and a storage medium, and the method comprises the steps: selecting a first feature set according to the importance evaluation score of a first operation parameter of a vehicle, and carrying out the training of the first feature set to obtain a side slip angle calculation model; the vehicle lateral acceleration, the steering wheel rotation angle and the left front wheel rotation angle speed of the to-be-measured vehicle are input into the side slip angle calculation model, the side slip angle of the to-be-measured vehicle is obtained through direct calculation, and the problem that in the prior art, the side slip angle is obtained through direct integration of a vehicle-mounted sensor signal, and consequently errors are large can be solved; and the problem that in the prior art, the calculation precision of the side slip angle is not high due to the fact that a kinetic model does not conform to the actual situation can also be solved, and therefore the calculation precision of the side slip angle is better guaranteed.
本申请公开了本申请提供一种车辆质心侧偏角计算方法和装置、电子设备及存储介质,该方案通过根据车辆第一运行参数的重要性评估分值选取第一特征集,根据第一特征集训练得到质心侧偏角计算模型后,将待测量车辆的车辆侧向加速度、方向盘转角和左前轮旋转角速度输入至质心侧偏角计算模型中,直接计算得到待测量车辆的质心侧偏角,能够避免现有技术中通过对车载传感器信号直接积分得到质心侧偏角而导致的误差较大的问题;也能够避免现有技术中动力学模型与实际情况不符而导致的质心侧偏角计算精度不高的问题,从而更好地保障质心侧偏角的计算精度。
