The invention belongs to the technical field of automobile steering control and relates to a steering control method for a four-wheel independent steering automobile. The steering control method includes: (1) by the aid of a data acquiring and processing module, acquiring and processing driver's steering intention information and automobile state information in real time; (2) by the aid of a steering mode judging module, judging a target steering mode as one of an adjusting mode, a four-wheel mode, a transition mode I or a transition mode II according to the data information in the step (1); (3) by the aid of a wheel steering angle calculating module, calculating wheel steering angles in the adjusting mode and wheel steering angles in the four-wheel mode according to the data information in the step (1); (4) by the aid of a steering mode coordination module, determining an executed steering mode of the automobile, calculating final wheel steering angles and transmitting to an execution module for execution according to results of the step (2) and the step (3). The steering control method for the four-wheel independent steering automobile has the advantages that the steering control problem of the four-wheel independent steering automobile is solved, use ratio of lateral force of wheels is increased, steering stability and steering safety of the automobile are improved, and energy consumption in steering is reduced.
