An electronic hydraulic braking system comprises an oil can, a hydraulic main cylinder, an auxiliary main cylinder, a simulation main cylinder, a driving mechanism, a pedal, a pedal simulator, a first pressure sensor, a stroke sensor, a first normally open valve, a first pipeline, a second pipeline, a third pipeline, a fourth pipeline and a control unit. The auxiliary main cylinder is in linkage connection with the hydraulic main cylinder, the driving mechanism is connected with the auxiliary main cylinder, the pedal is connected with the simulation main cylinder, and the stroke sensor is used for detecting the moving stroke of the pedal; the first pipeline and the second pipeline are connected with the hydraulic main cylinder; the third pipeline is connected between the auxiliary main cylinder and the simulation main cylinder, and the first normally open valve and the first pressure sensor are connected to the third pipeline; the fourth pipeline is connected between the simulation main cylinder and the pedal simulator; the control unit is connected with the driving mechanism, the stroke sensor, the first pressure sensor and the first normally open valve. The brake foot feeling can be guaranteed. The invention further provides an electronic hydraulic braking method.
