The invention provides a control method for a four-wheel drive hybrid electric vehicle. The control method comprises the following steps: A: in a travelling process of the four-wheel drive hybrid electric vehicle, detecting whether a brake pedal is depressed or not; B: if yes, further judging whether a first motor braking condition is satisfied or not; C: if the first motor braking condition is satisfied, further judging whether the maximum motor braking moment which can be provided by a back shaft driving motor of the vehicle is greater than or equal to moment required by braking; and D: if yes, providing the motor braking moment which is the same as the moment required by braking by the back shaft driving motor so as to bake the vehicle, and recovering energy for the motor brake. The control method disclosed by the invention can realize the purpose that regenerative braking and recovering is completely performed by the motor, and under the premise of ensuring the braking safety of the whole vehicle, recovering the braking energy is performed furthest, so that the recovery efficiency of the braking energy of the whole vehicle is improved.
