The invention discloses an automobile whistle warning system self-adaptive to automobile speed. The automobile whistle warning system involves an air control shifting sheet and a warning whistle whichis fixed to an automobile high-speed airflow passing area and provided with an adjustable opening, wherein a whistle ventilation opening blocking sliding block for adjusting the size of an opening ofthe warning whistle is arranged in the warning whistle, and the air control shifting sheet is connected with the whistle ventilation opening blocking sliding block. According to the automobile whistle warning system self-adaptive to automobile speed, the whistle sound is controlled by the air control shifting sheet, 1), the moving speed of an automobile can be automatically captured, automatic adjustment can be achieved, whistle warning sounds with different grades can be emitted, and the warning whistle sounds with different frequencies can be emitted at different automobile speeds to remindpedestrians to avoid, so that the effect of warning the pedestrians is realized; and 2), the whistle can be automatically closed when the moving speed of the automobile is too high, so that noise isavoided.

    本发明公开了一种自适应车速的汽车鸣哨警示系统,包括风控拨片以及固定于汽车高速气流通过区域的开口可调节的警示口哨,警示口哨内设置有调节警示口哨开口大小的口哨通风口阻塞滑块,风控拨片与口哨通风口阻塞滑块连接。本发明采用风控拨片控制哨音,1)可自动捕捉车辆运动速度,自动调节并发出不同档级的鸣哨警示音,可以在不同车速下发出不同频率的警示哨音提醒行人避让,从而实现警示行人的作用;2)可以在车辆运动速度过高时自行关闭口哨,避免发出噪音。
