The invention discloses a force closed-loop sliding-mode control method for an electronic mechanical braking system, and relates to the technical field of an EMB system of an electric vehicle, and the method comprises the steps: building a motor model according to the basic characteristics of a motor under a rotor synchronous coordinate system; and based on a novel power exponent reaching law, force closed-loop sliding mode control of the electronic mechanical braking system is constructed according to a motor model and a relational expression between clamping force and friction plate displacement. By designing the force closed-loop sliding mode control power exponent reaching law, the clamping force is controlled in real time, and the problems that under the condition that other coefficients of an existing sliding mode control reaching law are the same, the reaching speed of a state variable to a sliding mode surface s = 0 is low, and buffeting can be generated are solved.
