The invention discloses a four-wheel active steering control mode switching system which comprises a driving information measuring and calculating module, an active steering multi-mode switching threshold value parameter calculating module, an active steering mode selecting module and an active steering mode executing module. Wherein the driving information measuring and calculating module is used for measuring and calculating the vehicle speed, the road adhesion coefficient, the side slip angle, the yaw velocity, the lateral acceleration and the steering wheel turning angle; and the active steering multi-mode switching threshold value parameter calculation module is used for calculating a multi-mode switching threshold value in an interval between the comprehensive stability control factor and different road adhesion coefficients. The active steering mode selection module selects an automobile steering mode according to the active steering multi-mode switching threshold value parameter; the active steering mode execution module is used for switching automobile steering modes including an automobile front wheel steering mode, a four-wheel steering mode under sliding mode control and a four-wheel steering mode under optimal control.

    本发明公开了一种四轮主动转向控制模式切换系统,包括行驶信息测算模块、主动转向多模式切换门限值参数计算模块、主动转向模式选择模块、主动转向模式执行模块。其中,行驶信息测算模块用于测算车速、路面附着系数、质心侧偏角、横摆角速度、侧向加速度、方向盘转角;主动转向多模式切换门限值参数计算模块用于计算综合稳定控制因子与不同路面附着系数区间内的多模式切换门限值。主动转向模式选择模块根据主动转向多模式切换门限值参数对汽车转向模式进行选择;主动转向模式执行模块用于对汽车转向模式进行切换,包括汽车前轮转向模式、滑模控制下的四轮转向模式以及最优控制下的四轮转向模式。
