The invention discloses an electronic hydraulic braking system with a novel decoupling mode. The electronic hydraulic braking system comprises a brake pedal with a bolt, a ball screw with a sliding groove, a pedal displacement sensor, a braking main cylinder, a pressure sensor, a pedal simulator, an electronic control linear movement module and an ABS/ESP module. The bolt of the brake pedal is matched with the sliding groove of the ball screw to achieve mechanical decoupling. The braking main cylinder is hydraulically coupled with vehicle wheel brakes through the ABS/ESP module. The electronic control linear movement module drives a movement adjustment mechanism through a motor to drive a push rod to move, and the motor is controlled through a displacement signal to control the braking pressure. The ABS/ESP module can passively adjust the pressure conveyed to the wheel brakes through the main cylinder and can also actively adjust the pressure of the wheel brakes. By means of the electronic hydraulic braking system, rapid responding can be achieved, the hydraulic pressure can be accurately controlled, the brake pedal feeling of a driver can be actively simulated, and the electronic hydraulic braking system has the advantages of being simple in structure, easy to maintain and the like; meanwhile, the mechanical connection fail safe mode is designed, and the high safety and the high reliability are achieved.
