Braking system, braking method and automobile

A braking system comprises a pedal assembly (1), a hydraulic assembly (2), a reversing assembly (3), a driving wheel assembly, a pedal feeling simulator (6) and a first electronic control unit (7), the first electronic control unit (7) is electrically connected with the reversing assembly (3) and can control the reversing assembly (3) to switch working positions, and the reversing assembly (3) comprises at least two working positions. At the first working position, a brake fluid output port of the hydraulic assembly (2) is communicated with the driving wheel assembly through the reversing assembly (3). And at the second working position, the first electronic control unit (7) is electrically connected with the driving wheel assembly to control the driving wheel assembly to provide braking force. By means of the system, when a vehicle is in a normal working condition or a non-complete failure working condition, braking force is completely provided based on an electronic mechanical braking system and does not de
