This application provides a method and an apparatus for front and rear driving torque distribution of a vehicle, and a vehicle. The method includes: determining an expected status parameter existing during steering of a vehicle based on a wheel angle of the vehicle; determining a current correction yawing moment based on an actual status parameter existing during the steering of the vehicle and the expected status parameter, where the expected status parameter is determined based on the wheel angle of the vehicle; determining a mapping relationship between a correction yawing moment and a torque distribution coefficient based on the wheel angle and acceleration information of the vehicle; determining a torque distribution coefficient of the vehicle based on the current correction yawing moment and the mapping relationship; and determining front and rear axle driving torques of the vehicle based on the torque distribution coefficient of the vehicle. This improves operation stability during steering of a vehicle and provides high applicability.
