The invention discloses an electro-hydraulic power braking system for an automobile. The braking system comprises a signal sensing part, a calculating and controlling unit and a signal executing part, wherein a displacement sensor is connected with a brake pedal through a linkage rod; signals of the displacement sensor, a time signal generator, a wheel speed sensor and an automobile speed sensor are input into the calculating and controlling unit so as to calculate accelerated speed of the brake pedal and a wheel real-time slip ratio; a signal of a tire pressure and tire temperature sensor is input into the calculating and controlling unit through a signal transmitter and a signal receiver so as to calculate tire load coefficient; the calculating and controlling unit is used for controlling the value of the current of an input current amplifier according to the calculating result; under an effect of electromagnetic attraction forces generated by an electromagnetic coil and an iron core component, an armature is used for driving a piston to move down; and oil of both a power cylinder and a braking cylinder rapidly flows into a brake wheel cylinder so that the braking of the automobile is realized. The electro-hydraulic power braking system for the automobile, disclosed by the invention, is advantaged in that a brake power effect can be provided to a hydraulically-braked automobile; the braking is convenient and fast; the braking distance is reduced; and the safety of the automobile in running is improved.
