The invention discloses a four-wheel steering mode dynamic switching control system which comprises an automobile parameter acquisition module, a target steering mode wheel turning angle calculation module, a steering mode dynamic switching control module and a steering mode dynamic switching execution module. Wherein the automobile parameter acquisition module is used for acquiring automobile basic parameters and driving state information; the target steering mode wheel rotation angle calculation module is used for determining target wheel rotation angles of all steering modes of the automobile; the steering mode dynamic switching control module comprises an automobile steering mode judgment module, a steering mode dynamic switching transition state target wheel rotation angle calculation module, a steering mode dynamic switching transition module and an automobile steady state control module and is used for dynamically switching steering modes; and the steering mode dynamic switching execution module is used for sending the wheel turning angle output by the steering mode dynamic switching control module to an automobile steering controller, so that the automobile runs at the target wheel turning angle.
