The invention discloses an electro-hydraulic braking force distribution method for a pure electric vehicle. The method comprises the steps of establishing a kinematic model of vehicle sprung mass; discretizing the sprung mass kinematic model to obtain a vehicle state prediction model; and an objective function of a braking force distribution controller is established, constraint conditions of the objective function of the distribution controller are set, and a target motor braking torque and a target hydraulic braking torque are calculated according to the vehicle state prediction model and the objective function of the distribution controller. According to the method, the braking safety and the energy recovery efficiency can be balanced, and the electro-hydraulic braking force is reasonably distributed.
