The invention discloses a fault-tolerant control method and device for a four-wheel drive vehicle. The method comprises the steps that when the four-wheel drive vehicle runs abnormally due to the power problem, the movement state and vehicle body parameters of the vehicle are obtained, wherein the movement state comprises the speed, the yawing rate and the yawing inertia, and the vehicle body parameters comprise the vehicle weight, the tire effective rolling radius, the vehicle length, the engine output torque and the vehicle model equation; a torque control signal is determined according to the movement state and the vehicle body parameters. According to error diagnosis and fault-tolerant control based on dynamics for the four-wheel drive electric vehicle, the problem that a control signal cannot achieve adaptive change for engine torque errors in the prior art is solved, and the driving safety of the four-wheel drive vehicle is improved.
