The invention discloses a structure for producing sound by using automobile exhaust, a control method thereof and an exhaust system tail pipe. The structure for producing sound by using automobile exhaust comprises an exhaust main pipe and a vehicle-mounted controller, and further comprises a sounding exhaust pipe which is communicated with the exhaust main pipe and is controlled to be opened and closed through a first electric control valve, and a gas sounding device is arranged in the pipe. According to the control method, on the basis of manual control of a driver, the step of analyzing the current vehicle speed is added, the sound production mechanism can be turned on only when the vehicle speed is low, and the sound production mechanism is automatically turned off when the vehicle speed rises; and the exhaust system tail pipe comprises a sound production exhaust pipe and an exhaust tail pipe which are connected to an outlet of a silencer in parallel. When the vehicle is at a low speed, the sound production exhaust pipe is manually opened, the sound of the engine exhaust pipe can be increased, attention of pedestrians can be aroused, the vehicle can be reminded to avoid in time, especially in the starting and reversing stages of the vehicle, accidents at the tail of the vehicle can be effectively avoided, and after the valve is closed, an exhaust pipeline system further has a waterproof function and is simple in structure and easy to install and control.

    本发明公开了利用汽车尾气发声结构及其控制方法、排气系统尾管,该利用汽车尾气发声的结构包括排气主管和车载控制器,还包括一根与排气主管连通的通过第一电动调节阀控制开闭的发声排气管,在管内设有气鸣装置;该控制方法是在驾驶人手动控制的基础上,增加对当前车速分析步骤,只有在车速低时能打开发声机构,且车速升高则自动关闭;该排气系统尾管包括并联连接在消声器出口的发声排气管和排气尾管。在车辆低速时,手动打开发声排气管,可以增大发动机排气管的声音,引起行人的注意,提醒及时避让车辆,尤其在车辆起步、倒车阶段,能够有效避免车尾事故发生,且关闭阀门后,排气管路系统还具有防水功能,结构简单,安装操控容易。
