Abstract: In a method for front-rear driving torque distribution of a vehicle, a controlling apparatus determines an expected status parameter existing during steering of a vehicle based on a wheel angle of the vehicle. The controlling apparatus determines a current correction yawing moment based on an actual status parameter existing during the steering of the vehicle and the expected status parameter, and determines a mapping relationship between a correction yawing moment and a torque distribution coefficient based on the wheel angle and acceleration information of the vehicle. The controlling apparatus then determines a torque distribution coefficient of the vehicle based on the current correction yawing moment and the mapping relationship, and determines front and rear axle driving torques of the vehicle based on the torque distribution coefficient of the vehicle.

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.
