The invention discloses a bionic fin structure lateral airflow interference resisting device for a passenger car, and provides a device for reducing lateral airflow interference by analyzing a flow field of the passenger car when the passenger car passes through an object and referring to a self-balancing mode of a fish swinging fins. According to the device, a visual sensor is arranged at a rearview mirror in front of a vehicle; a fin plate driving motor and a fish-like fin plate are arranged at the tail of the vehicle; the visual sensor detects passenger car environment information; data istransmitted to ECU, whether to approach the object to drive is determined and a decision whether to rotate the fin plate driving motor or not is made; and finally, the data is transmitted to the fin plate driving motor of the fish-like fin plate, and the fin plate driving motor is controlled to execute corresponding actions so that the air flow field of the passenger car when the passenger car travels next to the object is changed, the lateral airflow interference is reduced, and a lateral force generated by a lateral airflow effect when the passenger car passes through the object is decreased. And meanwhile, for the passenger car running normally in a straight line, a fin plate unfolding angle of the bionic fin structure device is controlled, an air resistance coefficient can be effectively reduced, and the fuel economy of the passenger car is improved.

    一种用于客车的仿生鱼鳍结构抗侧向气流干扰装置,通过对客车经过物体行驶时的流场进行分析,借鉴鱼摆动鱼鳍进行自身平衡的方式,提出的一种减小侧向气流干扰的装置。该装置在车辆前车后视镜处布置视觉传感器,车尾布置鳍板驱动电机和仿鱼鳍板,视觉传感器检测客车环境信息,并将数据传输到ECU,判断是否将靠近物体行驶并作出是否转动鳍板驱动电机的决策,最后将数据传输至仿鱼鳍板鳍板驱动电机上,控制其执行相应动作,以改变客车在接下来的靠近物体行驶时的空气流场,减少侧向气流干扰,降低经过物体时侧向气流作用产生的侧向力。同时对于正常直线行驶的客车,控制仿生鱼鳍结构装置的鳍板展开角度,可以有效减低空气阻力系数提高客车燃油经济性。
