A wind resistance reducing device comprises an airflow dredging mechanism, the airflow dredging mechanism is arranged on the lower portion of a rear bumper, the airflow dredging mechanism is used for dredging airflow at the bottom of a vehicle to the rear portion of the vehicle, the airflow dredging mechanism is electrically connected with a whole vehicle control unit, and the whole vehicle control unit is used for controlling opening and closing of the airflow dredging mechanism according to the working condition of the vehicle. According to the wind resistance reducing device, when the vehicle is in a high-speed working condition, the airflow dredging mechanism is actively started, airflow at the bottom of the vehicle is dredged to the rear portion of the vehicle, the wind resistance coefficient of the vehicle is reduced to reduce energy consumption, when the vehicle is in a low-speed working condition, the airflow dredging mechanism is actively closed, the airflow at the bottom of the vehicle is blocked by a rear bumper, and the airflow direction deflects; the automobile wind resistance coefficient is increased, and the automobile safety performance is effectively improved. The invention further provides a wind resistance reducing method and a vehicle.
一种降风阻装置，包括气流疏导机构，气流疏导机构设于后保险杠的下部，气流疏导机构用于将车辆底部的气流疏导至车辆后部，气流疏导机构与整车控制单元电性连接，整车控制单元用于根据车辆的工况控制气流疏导机构的开启和关闭。该降风阻装置，当车辆处于高速工况时，主动开启气流疏导机构，将车辆底部的气流疏导至车辆后部，减小车辆风阻系数来降低能耗，当车辆处于低速工况时，主动关闭气流疏导机构，汽车底部气流受到后保险杠的阻挡，气流流向发生偏转，增大了汽车风阻系数，有效提高车辆安全性能。本发明还提供一种降风阻方法和一种车辆。
