The invention discloses an engine hood wind noise and wind resistance adjusting device and an adjusting method thereof. The engine hood wind noise and wind resistance adjusting device comprises a vehicle speed monitoring device, a control device, a driving device and an adjusting device, the vehicle speed monitoring device and the control device are both installed in a vehicle control system, and the driving device is installed in a vehicle head; the adjusting device is installed on an engine hood and located in front of a front windshield, and the vehicle speed monitoring device is used for monitoring the running speed of a vehicle. The control device is used for controlling the driving device to adjust at least one of the length of the adjusting device extending out of the engine hood and the deflection angle relative to the front windshield according to the running speed so as to reduce wind noise and wind resistance of the engine hood. The rotating angle of a rotating plate and the extension amount of an extension plate in the rear edge structure of the engine hood can be actively adjusted according to different vehicle speeds, so that wind noise and wind resistance of the automobile engine hood are reduced.

    本发明公开了一种引擎盖风噪和风阻调整装置及其调整方法,包括车速监控装置、控制装置、驱动装置以及调整装置,车速监控装置和控制装置均安装在整车控制系统中,驱动装置安装在车头内部,调整装置安装在引擎盖上且位于前挡风玻璃前方,车速监控装置用于监测车辆的行驶速度,控制装置用于根据行驶速度控制驱动装置调整调整装置伸出引擎盖的长度和相对于前挡风玻璃的偏转角度的至少其中之一来降低引擎盖风噪和风阻。本发明可以根据不同的车速主动调整引擎盖后沿结构中旋转板的旋转角度和延伸板的延伸量,来降低汽车引擎盖风噪和风阻。
