The invention discloses a tire slip angle determination method, system and equipment, a medium and a product, and relates to the field of intelligent tires. The method comprises the following steps: performing frequency domain analysis on an acceleration signal to obtain a frequency domain signal, extracting a vibration amplitude from the frequency domain signal, considering the influence of a vertical load and a tire pressure on the vibration amplitude, and inputting the vibration amplitude, the vertical load of a vehicle tire and the tire pressure of the vehicle tire into a constructed slip angle estimation model; the accurate estimation of the slip angle can be realized. Moreover, the support vector machine model is adopted to construct the side slip angle estimation model, so that the adaptability of the side slip angle estimation model can be improved, and the problems of low model adaptability, low precision, high equipment installation cost, difficulty in industrial application and the like in the prior art are solved.
