The invention discloses an intelligent early braking system of an electric automobile. The intelligent early braking system comprises an information acquisition module based on an automobile wireless communication technology, an early braking judgment module, an early braking starting sensitivity adaptation module, an early braking force calculation module and an early braking and normal braking connection module. The information acquisition module based on the vehicle wireless communication technology is used for acquiring various information between the vehicle and the surrounding environment; the pre-braking judgment module judges whether pre-braking is started or not according to a comparison result of the pre-braking demand degree characterization coefficient and a pre-braking starting threshold value; the early braking opening sensitivity adaptation module is used for calculating an early braking opening threshold value; the advance braking force calculation module adopts a near-end strategy optimization algorithm to calculate advance braking force; the early braking and normal braking connection module achieves reasonable transition between early braking and normal braking according to the braking connection rule.
