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: This application relates to the automobile field, and specifically, to a vehicle control method and apparatus, and the like. In the vehicle control method, when a steering mode of braking a rear wheel on an inner steering side is performed, target braking force of the rear wheel on the inner steering side is determined based on hand force applied when a driver performs a steering operation on a steering wheel, and steering control is performed based on the target braking force. In this way, steering control that well reflects an intention of the driver can be implemented, to avoid a case in which the driver frequently performs a driving operation to correct a traveling track of a vehicle, and reduce a driving burden. The method provided in embodiments of this application may be applied to an intelligent vehicle.
