The invention relates to a linear quadratic differential game based four-wheel active steering control method for a four-wheel independently-driven electric vehicle. The linear quadratic differentialgame based four-wheel active steering control method has the advantages that a front-wheel feedforward compensation control steering angle and a rear-wheel feedforward control steering angle are output by a feedforward controller, and serve as two 'players' in a game according to a linear quadratic differential game algorithm; a feedback Nash equilibrium solution of the differential game is acquired by solving the coupled algebraic Riccati equation set, and accordingly, the front-wheel feedforward compensation control steering angle and the rear-wheel feedforward control steering angle are acquired; the handling stability of the electric vehicle during high-speed steering and the handling flexibility thereof during low-speed steering can be improved through four-wheel active drive based onthe combination of feedforward control with feedback control; the side slip angle of the vehicle is effectively decreased under the premise of not changing the driver's feeling about conventional front wheel steering, the ideal yaw velocity of the vehicle can be well tracked, and the active safety performance of the vehicle is improved.
