HYDRAULIC BRAKE SYSTEM AND GAS DISCHARGE CONTROL METHOD THEREFOR, CONTROLLER, AND VEHICLE

This application provides a hydraulic brake system, an exhaust control method thereof, a controller, and a vehicle, and relates to the field of electronic technologies in the field of automobiles. In the hydraulic brake system provided in this application, a pressurizing assembly can output brake fluid to a brake fluid transmission assembly under control of a controller. The brake fluid transmission assembly can connect the pressurizing assembly to a brake control assembly or a brake assembly under control of the controller, so as to exhaust gas in the assembly connected to the pressurizing assembly. Because the controller can control the pressurizing assembly and the brake fluid transmission assembly to automatically perform an exhaust operation, and the exhaust process does not require manually stepping on a brake pedal, the controller is applicable to a wire-controlled brake system of a future vehicle (for example, an intelligent driving vehicle). Moreover, because the pressurizing assembly is realized by using a motor, a piston and a pressurizing cylinder, fine control of an outlet amount of the brake fluid can be realized.
