The invention provides a hydraulic integrated brake-by-wire system, and belongs to the field of automobile brake systems, the hydraulic integrated brake-by-wire system comprises a main cylinder, a first piston, a second piston, a first oil can, a second oil can and an energy accumulator, the first piston and the second piston divide an inner cavity of the main cylinder into a first cavity, a second cavity and a third cavity, and the end, away from the main cylinder, of the first piston is connected with a pedal; a first loop and a second loop are connected between the second cavity and the wheel cylinder set, a third loop is connected between the first cavity and the wheel cylinder set, an oil pump is connected to the first loop in series, the energy accumulator is located between the oil pump and the second cavity, the first oil can is communicated with the first cavity through a pipeline, and the second oil can is communicated with the second cavity and the wheel cylinder set through pipelines. And the first oil pot and the second oil pot are mutually independent. The problem that an existing electronic hydraulic braking system is limited in redundancy capacity is solved. The method has the technical effects that reliable voltage buildup with higher power and higher braking response speed are realized, and the braking effect of redundant braking is ensured while braking decoupling is realized.
