Abstract: This application provides a brake-by-wire system and a control method. This application is applicable to an intelligent vehicle, a new energy vehicle, a conventional vehicle, or the like. The braking control system includes: a brake master cylinder, a first pressure booster, a second pressure booster, at least one second control valve, at least one third control valve, at least one fourth control valve, and a second pedal feel simulation system. When a master brake system fails, a redundant brake system can independently control each brake wheel cylinder, to implement function backup for a master brake system, meeting requirements for braking functions such as ABS/AEB/ESC/TCS of a vehicle. The redundant brake system can further improve safety of the brake system and ensure pedal experience of a driver, thereby bringing more stable and comfortable driving experience to the driver.

Abstract: A hydraulic control unit is provided, including a hydraulic control apparatus with a bidirectional pressurization function, where the hydraulic control apparatus includes a second hydraulic chamber and a first hydraulic chamber. The second hydraulic chamber provides a braking force for a first group of wheel cylinders through a first brake line provided with a first control valve. The first hydraulic chamber provides a braking force for a second group of wheel cylinders through a second brake line provided with a second control valve.
