An automobile drive-by-wire electronic hydraulic braking system comprises a hydraulic pump assembly of a high-pressure energy accumulator, a hydraulic control unit, an electronic control unit and an ABS/ESC unit. The hydraulic control unit comprises a sensor group, a liquid storage tank, a main cylinder, a pedal simulator, a normally closed electromagnetic valve group and a normally open electromagnetic valve group; the sensor group is in signal connection with the electronic control unit and comprises a high-pressure energy accumulator pressure sensor and a displacement sensor; the normally-closed solenoid valve group comprises a first-path pressurizing normally-closed solenoid valve, a second-path pressurizing normally-closed solenoid valve, a first-path pressure-reducing normally-closed solenoid valve, a second-path pressure-reducing normally-closed solenoid valve and a second-stage normally-closed solenoid valve; and the normally open solenoid valve group comprises a first normally open solenoid valve and a second normally open solenoid valve which are arranged between the main cylinder and the ABS/ESC unit. Therefore, the automobile drive-by-wire electronic hydraulic braking system can replace a traditional vacuum booster braking system, and the conventional braking function and the active braking function are achieved.
