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.

    本发明公开了一种基于智能电动汽车的转向模式切换方法,包括基于无线车辆感知系统的信息采集模块、行驶状态综合评价模块、转向模式选择模块和转向行驶单元执行模块。所述基于无线车辆感知系统的信息采集模块用于获取车辆和驾驶员状态等多维信息;所述行驶状态综合评价模块结合车辆行驶状态因子、路况与环境因子、驾驶员行为和反应因子、轮胎动态特性因子、车辆动态稳定性因子,构建全连接神经网络模型,输出行驶状态综合评价因子;所述转向模式选择模块根据行驶状态综合评价因子与各个转向模式阈值的大小关系,选择前轮转向模式、四轮转向模式或斜向转向模式;所述转向行驶单元执行模块根据所选模式,计算各车轮的转角并控制其动作。
