Abstract: A hydraulic brake system includes a pressurizing assembly that is configured to output brake fluid to a brake fluid transmission assembly under control of a controller. The brake fluid transmission assembly is configured to connect the pressurizing assembly to a brake control assembly or a brake assembly under control of the controller to exhaust gas in the assembly connected to the pressurizing assembly.

Abstract: This application discloses a brake assembly, a brake system, a vehicle, and a brake system control method. The brake assembly includes a cylinder body, a piston, an elastic piece, and a driving piece. The piston is mounted in an inner cavity of the cylinder body, so that the piston and the inner cavity of the cylinder body form an accommodating cavity. The driving piece and the elastic piece are disposed in the accommodating cavity, and the driving piece is connected to the piston through the elastic piece. The driving piece drives, through the elastic piece, the piston to move, so as to drive a brake to brake. When braking is canceled, the elastic piece can provide a pulling force for the piston, so that the piston is reset quickly. Therefore, the solutions can help reduce a dragging torque, reduce travel resistance of a vehicle.

Abstract: A command processing method to reduce a system delay and system complexity while ensuring system consistency. A server receives from a client a target request that carries a target command. The server uses a current time as a target timestamp of the target request, adds a local associated command corresponding to the target context number and a local conflicted command corresponding to the target command to a target dependency set, and forwards the target request to a replica server. The server updates the target dependency set according to a feedback from the replica server, and stores an updated target dependency set synchronously with the replica server. And the server determines a target execution sequence of the target command and each command in the updated target dependency set.
