Abstract: A vehicle control method includes whether a vehicle slips is detected by using a difference between an acceleration of a drive wheel and a traveling acceleration of the vehicle and/or a difference between a speed of the drive wheel and a traveling speed of the vehicle. When the drive wheel slips, drive torque output by a drive apparatus to the slipping drive wheel is controlled to be less than required torque, to ensure safety of the vehicle. Further, a slip rate of the drive wheel and a road condition of a road on which the vehicle is located are used as specific control constraints. When the vehicle is a four-wheel drive vehicle, the control method may further implement transfer and reallocation of drive torque.

Abstract: This application discloses a method and an apparatus for activating an ESC of an intelligent driving vehicle. In this method, an ESC activation probability is obtained after an intelligent driving function of the intelligent driving vehicle is enabled. A pre-exit signal of an ADS and a warning signal are outputted when the ESC activation probability is greater than a preset latch interval. The pre-exit signal indicates the ADS to maintain stability of a traveling status of the intelligent driving vehicle. The warning signal prompts a driver to take over the intelligent driving vehicle. A stability parameter of the intelligent driving vehicle is obtained, where the stability parameter represents a stability characteristic of the traveling status of the intelligent driving vehicle. When the stability parameter meets an ESC activation condition, the ESC of the intelligent driving vehicle is activated.

Abstract: A vehicle control method includes responding to a case in which a vehicle in an automatic driving mode enters an unstable state by determining a second torque change rate based on a first torque change rate obtained when the vehicle enters the unstable state, where the second torque change rate is less than the first torque change rate, and periodically calculating torque of the vehicle based on the second torque change rate using torque obtained when the vehicle enters the unstable state as an initial value, controlling the vehicle by using the calculated torque of the vehicle until the vehicle exits the automatic driving mode, and controlling the vehicle based on torque obtained when the vehicle exits the automatic driving mode.

An apparatus for implementing the method, an electronic device, a vehicle, and a storage medium storing the method are further provided.

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: 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.
