The invention relates to the field of automobile components, and discloses an electrically-controlled hand brake valve. The electrically-controlled hand brake valve comprises a fixing frame (2); the fixing frame (2) is provided with a handle (1), and the handle (1) rotates on the fixing frame (2); and the fixing frame (2) is provided with an angle position sensor (3), and the angle position sensor (3) is used for detecting the rotating angle of the handle (1). The electrically-controlled hand brake valve further comprises an integrated control module (5), an air pressure controller (6) and an air outlet (8). The rotating angle of the handle (1) is transmitted to the integrated control module (5) through the angle position sensor (3). The integrated control module (5) works out the air pressure value of the air outlet (8) on the basis of the rotating angle of the handle (1) and transmits the air pressure value to the air pressure controller (6). The air pressure controller (6) is used for controlling air pressure output of the air outlet (8). The electrically-controlled hand brake valve has the effects that stable air pressure output of the air outlet is controlled, the braking effect of the hand brake valve is improved, and the safety of automobile running is improved.
