The invention discloses a four-wheel drive hybrid electric vehicle, a drive anti-slip control method and a device. The method comprises steps: a slip rate signal, required torque of an engine in the four-wheel drive hybrid electric vehicle and required torque of a drive motor are acquired; the slip rate signal is used for judging whether wheels in the four-wheel drive hybrid electric vehicle are in a slip state; and if the wheels in the four-wheel drive hybrid electric vehicle are judged to be in the slip state according to the slip rate signal, the required torque of the engine and the required torque of the drive motor are adjusted, and the required torque of the engine and the required torque of the drive motor after adjustment are used for carrying out drive anti-slip control on the four-wheel drive hybrid electric vehicle. Through adjusting the required torque of the engine and the required torque of the drive motor at the best time and carrying out synthesis and arbitration on the required torque of the engine and the required torque of the drive motor after adjustment according to the vehicle speed, the steering sensor angle and the slip rate signal transmitted by an ESP, the phenomenon of vehicle slip can be quickly eliminated, and the drive performance of the vehicle is improved.
