The invention discloses a steering mode switching method based on an intelligent electric vehicle. An information acquisition module based on a wireless vehicle sensing system, a driving state comprehensive evaluation module, a steering mode selection module and a steering driving unit execution module are included. The information acquisition module based on the wireless vehicle sensing system is used for acquiring multi-dimensional information such as vehicle and driver states; the driving state comprehensive evaluation module combines a vehicle driving state factor, a road condition and environment factor, a driver behavior and reaction factor, a tire dynamic characteristic factor and a vehicle dynamic stability factor to construct a full-connection neural network model, and outputs a driving state comprehensive evaluation factor; the steering mode selection module selects a front-wheel steering mode, a four-wheel steering mode or an oblique steering mode according to the size relationship between the driving state comprehensive evaluation factor and each steering mode threshold value; and the steering driving unit execution module calculates the turning angle of each wheel and controls the action of each wheel according to the selected mode.
