The invention discloses a drive-by-wire hydraulic brake system and method, and relates to the technical field of automobile braking. The drive-by-wire hydraulic brake system comprises a controller, a brake oil pot, a motor pressurization system, a mechanical pressurization system, a pedal simulation system, an electromagnetic valve, a brake and a first one-way valve; the motor pressurization system is connected with the brake oil pot; the brake oil pot, the mechanical pressurization system and the pedal simulation system are connected in pairs; the motor pressurization system and the mechanical pressurization system are connected with the brake through the magnetic valve; and the controller is connected with the motor pressurization system, the mechanical pressurization system, the pedal simulation system and the electromagnetic valve. The good brake pedal feeling is achieved, meanwhile, brake energy is recycled, automatic brake pressurization can be achieved, deceleration brake of a vehicle is completed, and when a motor active brake pump fails, a driver can step on a brake pedal, and safe brake is achieved. The structure replaces a traditional vacuum booster, braking energy can be recycled, and the battery energy utilization rate is increased.
