BRAKE SYSTEM, BRAKE METHOD AND VEHICLE

A braking system includes a pedal assembly (1), a hydraulic assembly (2), a reversing assembly (3), a driving wheel assembly, a pedal feel simulator (6), and a first electronic control unit (7), where the first electronic control unit (7) is electrically connected to the reversing assembly (3), and may control the reversing assembly (3) to switch a working location, and the reversing assembly (3) includes at least two working locations. When the reversing assembly is at a first working location, a brake fluid output port of the hydraulic assembly (2) is connected to the driving wheel assembly through the reversing assembly (3). When the reversing assembly is at a second working location, the first electronic control unit (7) is electrically connected to the driving wheel assembly, and controls the driving wheel assembly to provide brake force. In the system, when a vehicle is in a normal working condition or a non-complete failure working condition, brake force is provided entirely by an electro-mechanical braking system, without depending on a hydraulic system. When the vehicle is in a complete failure working condition, brake force can be provided by the hydraulic system in a manner that a driver steps on a brake pedal.
