A torque distribution method for four-wheel drive of an electric vehicle, and a system and a vehicle. The method includes: acquiring the total demanded torque of a whole vehicle; determining a demand state of the whole vehicle according to traveling parameter information obtaining a first front and rear axle torque distribution coefficient according to a mathematical model of front and rear axle driving force when front and rear wheels slip simultaneously, and according to the total demanded torque of the whole vehicle; obtaining the front and rear axle torque distribution coefficient according to the first front and rear axle torque distribution coefficient; and obtaining target torque of front and rear driving system according to the front and rear axle torque distribution coefficient and the total demanded torque of the whole vehicle. The best road adhesion performance and the highest driving efficiency of a vehicle can be realized.
