Problems solved by technology

However, when the vehicle is moving, especially at a high speed, the open sunroof will generate greater wind noise, and the wind noise will increase accordingly with the increase of the speed of the vehicle, thereby seriously affecting the comfort of the vehicle. The sunroof will affect the ventilation

Embodiment 1

[0043] figure 1 It is a flow chart of steps of a noise reduction control method for skylights provided by an embodiment of the present invention.

[0044] The noise reduction control method provided in this embodiment is applied to a sunroof controller of an automobile, and is used to enable the sunroof controller to perform noise reduction control on the sunroof of the automobile, so that users can obtain higher riding comfort by controlling the opening of the sunroof.

[0045] Such as figure 1 As shown, the noise reduction control method in this embodiment specifically includes the following steps:

[0046] S101: Determine whether noise reduction processing is required according to the current interior noise of the car or the setting state of the user.

[0047] Firstly, the current interior noise and setting state of the car are detected. Wherein, the current interior noise refers to the interior noise intensity of the automobile, and the detection of the noise intensity ...

Embodiment 2

[0068] Figure 4 It is a structural block diagram of a noise reduction control device for a sunroof provided by an embodiment of the present invention.

[0069] The noise reduction control device provided in this embodiment is applied to a sunroof controller of an automobile, and is used to enable the sunroof controller to perform noise reduction control on the sunroof of the automobile, so that users can obtain higher riding comfort by controlling the opening of the sunroof.

[0070] Such as Figure 4 As shown, the noise reduction control device in this embodiment specifically includes a noise reduction demand judgment module 10 , a target opening degree reading module 20 and a sunroof adjustment control module 30 .

[0071] The noise reduction demand judging module is used to judge whether noise reduction processing is required according to the current interior noise of the car or the user's setting state when the sunroof of the car is in an open state. The module specific...

Embodiment 3

[0089] Figure 5 It is a structural block diagram of another noise reduction control device for a sunroof provided by an embodiment of the present invention.

[0090] Such as Figure 5 The noise reduction control device provided in this embodiment is based on the previous embodiment with an additional shutdown control module 40 .

[0091]Since the vehicle speed corresponding to the corresponding target control opening in the dynamic noise reduction table is in a relatively wide range, when the vehicle speed is high, the noise in the car is still high after the above control, that is, the current noise in the car is still greater than the preset The second noise threshold, if the opening width and lift angle of the sunroof glass are the minimum values ​​that can be controlled at this time, it is the minimum value in the above dynamic noise reduction table. In order to further control the noise inside the car, directly Close the sunroof glass completely.

[0092] The preset s...

Abstract

The invention discloses a skylight noise reducing control method and device, and a skylight controller. The method and device are applied to the skylight controller of a car, and the noise reducing control method comprises the steps that when a skylight of the car is in an opening sate, whether noise reduction treatment is needed or not is judged according to current in-car noise of the car or a set state of a user; when the noise reduction treatment is needed, read operation is conducted from a preset dynamic noise reduction meter according to the current in-car noise or the current car speedof the car, and the target control opening degree of a skylight is obtained; and skylight glass of the skylight is controlled to act so as to make the current opening degree of the skylight glass reach the target control opening degree. Through control over the current opening degree of the skylight by the scheme, the current in-car noise can be effectively reduced, namely, the in-car noise caused by wind noise of the skylight during running of the car is effectively reduced, and thus the ride comfort of the car is improved effectively.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and device for noise reduction control of a sunroof and a sunroof controller. Background technique [0002] At present, the proportion of cars equipped with sunroofs is getting higher and higher, which can effectively circulate the air in the car and increase the entry of fresh air, thereby effectively improving the air quality in the car. However, when the vehicle is moving, especially at a high speed, the open sunroof will generate greater wind noise, and the wind noise will increase accordingly with the increase of the speed of the vehicle, thereby seriously affecting the comfort of the vehicle. The skylight will affect the ventilation. Contents of the invention [0003] In view of this, the present invention provides a sunroof noise reduction control method, device and sunroof controller, which are used to reduce the wind noise of the sunroof when the car is r...
