The invention discloses a braking control method for a new energy commercial vehicle, and relates to the technical field of new energy vehicle braking. Determining an electric braking parameter and a mechanical braking parameter according to the target deceleration of the vehicle; determining an electric braking torque and a mechanical braking torque according to the electric braking parameter and the mechanical braking parameter; controlling the vehicle to brake according to the electric brake torque and the mechanical brake torque; wherein the step of determining the electric braking parameters and the mechanical braking parameters according to the target deceleration of the vehicle comprises the steps that when the target deceleration of the vehicle is smaller than a first preset deceleration, the electric braking parameters are calculated according to a first regression curve equation about the target deceleration of the vehicle; and when the target deceleration of the vehicle is greater than a second preset deceleration, calculating the mechanical braking parameter according to a second regression curve equation about the target deceleration of the vehicle. And the problem that the sudden change of the braking force is large under the unstable critical working condition of the vehicle due to gradual braking is solved.
