Description
Technical Field
The invention belongs to the technical field of optimizing sound quality in a vehicle at different vehicle speeds, and relates to a height-adjustable passenger vehicle skylight guide plate control system for optimizing sound quality.
Background
The skylight guide plate is used for inhibiting the wind vibration phenomenon when the driving skylight is opened, but for most vehicles, after the vehicle speed exceeds about 70km/h, the wind vibration phenomenon disappears, and the existence of the guide plate degrades the sound quality of wind noise in the vehicle. Fig. 1a, 1b, 1c show the effect on wind vibration and wind noise quality with respect to the height of the deflector. The use of the deflector can restrain the wind vibration intensity when running at low speed, and most skylights are required to be equipped with the deflector. When the vehicle runs at a high speed, wind vibration does not exist, and the guide plate can cause the quality of wind noise in the vehicle to be reduced, as shown in fig. 1a, 1b and 1c, the hoarseness improves the sharpness of sound, and reduces the sound quality.
The guide plate of the current vehicle can be automatically lifted after the window is opened, and the guide plate can not be changed no matter whether wind vibration exists or not, so that the sound quality is low under certain vehicle speeds.
The guide plate is installed under passenger car skylight opening mode and is designed for solving the wind vibration problem, and the skylight guide plate of all motorcycle types only has a fixed height at present to just get into operating mode as long as the skylight is opened, do not have the guide plate of adjustable height yet. The initial purpose of the skylight guide plate is to solve the skylight wind vibration problem at low speed (the speed of the vehicle is less than 70 Km/h). But the presence of the backflow plate affects the quality of the stale wind noise. In the high-speed condition, the guide plate causes the quality of wind noise in the automobile to be reduced, and the problem of wind vibration under the high-speed working condition (the automobile speed is more than 70Km/h) does not exist, so that the existence of the guide plate is completely redundant and the quality effect of the generated riding sound is negative. Different markets and different crowds have different comprehensive feelings on loudness, roughness, sharpness and speech definition indexes in the car at different wind speeds, and the skylight guide plate of the passenger car with the adjustable height can be used for realizing accurate control on the sound quality of the whole car of the passenger car. The optimal height control strategy of the sound quality of the guide plate under different vehicle speeds can be worked out in a skylight wind noise development test in a passenger vehicle development stage, so that the guide plate can automatically adjust the height under a windowing mode according to the actual working condition, and the subjective perception of the sound quality of drivers and passengers is improved.
