The invention discloses an intelligent control method and system for a drum-type inhaul cable electronic parking system and electronic equipment, and the method comprises the steps: dynamically predicting the mechanical overshoot risk through monitoring the current rising trend (including an instantaneous value and a change rate) in real time based on the motor current characteristics of an inhaul cable-type EPB at a release tail end, and adaptively adjusting the target rotating speed of a motor according to the mechanical overshoot risk. And the mechanical inertia is counteracted by actively suppressing the kinetic energy of the system, so that the release action is accurately stopped. According to the method, on the premise that extra hardware cost is not increased, real-time detection and inhibition of excessive release of the inhaul cable are achieved, inhaul cable loosening, clamping response delay and abnormal abrasion of an internal mechanical structure of a braking system caused by the fact that the release stroke is too large are effectively avoided, and the service life of the braking system is prolonged. And the working reliability of electronic parking braking and the parking safety level of the whole vehicle are obviously improved.
