The invention provides a tire slip angle estimation method and device, electronic equipment and a storage medium, and relates to the technical field of vehicle control. The tire slip angle estimation method comprises the following steps: acquiring an acceleration physical quantity sensed when a target position on a tire rotates into a preset area, and obtaining an acceleration signal changing along with time in a first time period; wherein the preset area comprises an area in which the acceleration physical quantity is associated with the tire slip angle; performing time-frequency conversion on the acceleration signal, and extracting spectrum feature information of the acceleration signal; and inputting the frequency spectrum characteristic information into a pre-trained tire slip angle estimation model to obtain an estimated value of the tire slip angle of the tire. The problem that the estimation precision of the tire slip angle is low can be solved.

    本公开提供了一种轮胎侧偏角的估计方法、装置、电子设备及存储介质,涉及车辆控制技术领域。轮胎侧偏角的估计方法包括:获取轮胎上目标位置旋转至预设区域内感应到的加速度物理量,得到第一时间段内随时间变化的加速度信号;其中,预设区域包括加速度物理量与轮胎侧偏角存在关联的区域;将加速度信号进行时频转换,提取加速度信号的频谱特征信息;将频谱特征信息输入至预先训练好的轮胎侧偏角估计模型中,得到轮胎的轮胎侧偏角的估计值。本公开能够解决轮胎侧偏角的估计精度较低的问题。
