The invention provides an electronic hydraulic brake system considering operation characteristics of a driver pedal. The electronic hydraulic brake system comprises a brake pedal, a brake pedal sensor set, a pedal simulation assembly, an electronic hydraulic brake assembly, a brake pressure compensation assembly, an ABS/ESP module and a main control module. The electronic hydraulic brake assembly comprises a main motor, a main motor torque sensor, an oil tank, a hydraulic pump, an electromagnetic reversing valve, a main hydraulic cylinder, a secondary hydraulic cylinder, a brake main cylinder and a pressure sensor. The main control module is electrically connected with the brake pedal sensor set, the pedal simulation motor, the pedal motor torque sensor, the main motor, the main motor torque sensor, the electromagnetic reversing valve, the pressure sensor and the brake pressure compensation assembly. The invention further provides a control method of the electronic hydraulic braking system based on the driver
