The invention provides an active aerodynamics suite control system based on a four-wheel steering passenger vehicle. The active aerodynamics suite control system comprises a vehicle state information acquisition unit, an active aerodynamics suite control index calculation unit, an active aerodynamics suite mode selection unit and an active aerodynamics suite mechanism unit. The vehicle state information acquisition unit is used for receiving vehicle state information acquired by the sensor in real time; the active aerodynamic suite control index calculation unit is used for calculating a vehicle driving state evaluation factor and each aerodynamic suite action weight factor; the active aerodynamic suite mode selection unit is used for selecting an active aerodynamic suite working mode suitable for current road conditions and vehicle working conditions from a dynamic mode, an energy-saving mode and an emergency braking mode according to the vehicle state information; and the active aerodynamic suite mechanism unit is used for executing a specified action according to the selected active aerodynamic suite working mode.

    本发明提供了一种基于四轮转向乘用车的主动空气动力学套件控制系统,包括车辆状态信息采集单元、主动空气动力学套件控制指标计算单元、主动空气动力学套件模式选择单元、主动空气动力学套件机构单元。车辆状态信息采集单元用于接收来自传感器实时采集的车辆状态信息;主动空气动力学套件控制指标计算单元用于计算车辆行驶状态评价因子与各空气动力学套件动作权重因子;主动空气动力学套件模式选择单元用于根据车辆状态信息,从动态模式、节能模式与紧急制动模式中选择适合当前道路条件与车辆工况的主动空气动力学套件工作模式;主动空气动力学套件机构单元用于根据所选主动空气动力学套件工作模式执行指定动作。
