The invention provides a control method for a four-wheel-driven hybrid electric vehicle. The control method comprises the first step of detecting ignition key signals, torque required by the vehicle, the charge state of a power battery and vehicle speed signals, and the second step of controlling the vehicle to switch between multiple working modes according to the ignition key signals, the torque required by the vehicle, the charge state of the power battery and the vehicle speed signals. According to the control method, the multiple working modes are adopted, and the advantages of four-wheel-driven hybrid power can be given to full play. Through switching between the multiple working modes, the vehicle can be in an optimal working state all the time, so that fuel consumption is lowered. In addition, through distribution of the torque of all components in different working modes, the working efficiency of an engine, an ISG motor and a rear axle motor can be optimized, so that the fuel consumption of the whole vehicle is further lowered.
