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.
