The embodiments described below with reference to the accompanying drawings are exemplary, only used to explain the present invention, and should not be construed as a limitation of the present invention.
下面参考图1和图2描述根据本发明实施例的用于车辆的降噪方法。A noise reduction method for a vehicle according to an embodiment of the present invention will be described below with reference to FIGS. 1 and 2 .
根据本发明的用于车辆的降噪方法包括至少如下步骤：The noise reduction method for a vehicle according to the present invention comprises at least the following steps:
S1：将车辆信息、道路信息、附近车辆信息、障碍物信息、环境信息上传至星链系统；S1: Upload vehicle information, road information, nearby vehicle information, obstacle information, and environmental information to the Starlink system;

S3：车辆根据声场声压信息采集降噪措施。S3: The vehicle collects noise reduction measures according to the sound field sound pressure information.
也就是说，本发明的用于车辆的降噪方法可以采集更加全面的声源和声场信息，相较于现有技术中采集的信息更加广泛，不仅包括自身车辆的信息，还可以采集道路信息以及附近车辆的信息，另外车辆周围的环境信息也可以被采集，从而不仅可以即时地计算车辆周围的声场和声压，还可以预测车辆即将碰到的噪声源，提前计算好反相的声源，在碰到突发的噪声后也能够提前应对。That is to say, the noise reduction method for vehicles of the present invention can collect more comprehensive sound source and sound field information, which is more extensive than the information collected in the prior art, including not only the information of the own vehicle, but also road information. As well as the information of nearby vehicles, and the environmental information around the vehicle can also be collected, so that not only the sound field and sound pressure around the vehicle can be calculated in real time, but also the noise source that the vehicle is about to encounter, and the opposite-phase sound source can be calculated in advance. , and can also respond in advance after encountering sudden noise.
根据本发明的用于车辆的降噪方法，采集的声音信息不仅包括车辆自身信息，还包括车辆排气、周围车辆、道路形貌、其他障碍物、雷雨等天气因素等综合因素对车辆周围声场的影响，星链系统结合气象云平台和北斗导航系统，具有较高的精确度和集成度，通过量子计算实时计算车辆周围的噪声声压，进而通过车载噪声处理系统进行主动降噪。According to the noise reduction method for a vehicle of the present invention, the collected sound information not only includes the vehicle's own information, but also includes comprehensive factors such as vehicle exhaust, surrounding vehicles, road topography, other obstacles, thunderstorms and other weather factors that affect the sound field around the vehicle. The Starlink system combines the meteorological cloud platform and the Beidou navigation system with high accuracy and integration. It calculates the noise sound pressure around the vehicle in real time through quantum computing, and then uses the on-board noise processing system for active noise reduction.
在本发明的一些实施例中，车辆信息包括车辆的外观尺寸、车速以及车辆的位置。车辆的外观尺寸、车辆的速度以及车辆的位置可以对车辆周围的声场产生影响，将车辆信息上传到星链系统中，可以提高计算车辆周围声场声压的精度，为后续的降噪措施提供前提条件，使得车辆的降噪效果更好。In some embodiments of the present invention, the vehicle information includes the exterior dimensions of the vehicle, the speed of the vehicle, and the location of the vehicle. The appearance size of the vehicle, the speed of the vehicle and the position of the vehicle can have an impact on the sound field around the vehicle. Uploading the vehicle information to the Starlink system can improve the accuracy of calculating the sound pressure of the sound field around the vehicle and provide a prerequisite for subsequent noise reduction measures. conditions, so that the noise reduction effect of the vehicle is better.
当然，需要说明的，本发明的车辆信息不限于车辆的外观尺寸、车速以及车辆的位置，本发明不对车辆的信息进行具体限定。Of course, it should be noted that the vehicle information of the present invention is not limited to the appearance size, speed and position of the vehicle, and the present invention does not specifically limit the information of the vehicle.
进一步地，所述车辆信息还包括：车辆的排气信息和车窗开度信息。车辆的排气信息和车窗的开度都会对车辆内部获取的噪音的强度的方向产生影响，因此将车辆的排气信息与车窗的开度信息上传到星链系统，可以提高计算车辆周围声场声压的精度，为后续的降噪措施提供前提条件，使得车辆的降噪效果更好。Further, the vehicle information further includes: exhaust information and window opening information of the vehicle. The exhaust information of the vehicle and the opening of the windows will both affect the direction of the intensity of the noise obtained inside the vehicle. Therefore, uploading the exhaust information of the vehicle and the opening of the windows to the Starlink system can improve the calculation of the surrounding area of the vehicle. The accuracy of the sound pressure in the sound field provides preconditions for subsequent noise reduction measures, so that the noise reduction effect of the vehicle is better.
在本发明的一些实施例中，道路信息包括道路的类型、道路的坡度以及道路的摩擦力。道路的类型以及道路的坡度会影响到车辆与地面之间的路噪，而车辆与道路的摩擦力也能够影响车辆的路噪。显然相同速度下，柏油马路上车辆产生的路噪要小于在石子路上产生的路噪。将道路的类型、道路的坡度以及道路的摩擦力上传到星链系统，可以提高计算车辆周围声场声压的精度，为后续的降噪措施提供前提条件，使得车辆的降噪效果更好。In some embodiments of the present invention, the road information includes the type of road, the grade of the road, and the friction of the road. The type of road and the slope of the road can affect the road noise between the vehicle and the ground, and the friction between the vehicle and the road can also affect the road noise of the vehicle. Obviously, at the same speed, the road noise generated by vehicles on the asphalt road is less than that generated on the gravel road. Uploading the type of road, the slope of the road and the friction force of the road to the Starlink system can improve the accuracy of calculating the sound pressure of the sound field around the vehicle, provide preconditions for subsequent noise reduction measures, and make the noise reduction effect of the vehicle better.
当然，需要理解的是，本发明的道路信息不限于道路的类型、道路的坡度以及车辆与道路的摩擦力，本发明不对道路信息进行具体限定。Of course, it should be understood that the road information of the present invention is not limited to the type of the road, the gradient of the road, and the friction between the vehicle and the road, and the present invention does not specifically limit the road information.
在本发明的一些实施例中，反相附近车辆信息包括：附近车辆的速度、附近车辆相对于本车的位置以及附近车辆的外观尺寸。将附近车辆信息上传到星链系统中，可以提高计算当前车辆周围声场声压的精度，为后续的降噪措施提供前提条件，使得车辆的降噪效果更好。In some embodiments of the present invention, the inverted nearby vehicle information includes: the speed of the nearby vehicle, the position of the nearby vehicle relative to the own vehicle, and the appearance size of the nearby vehicle. Uploading the information of nearby vehicles to the Starlink system can improve the accuracy of calculating the sound pressure of the sound field around the current vehicle, provide preconditions for subsequent noise reduction measures, and make the noise reduction effect of the vehicle better.
在本发明的一些实施例中，障碍物信息包括行人、动物、减速带等。障碍物包括即将碰撞到或者车辆周围阻碍车辆前进的物体。例如，在车辆前方有减速带时，星链可以计算车辆距离前方的减速带之间的距离以及到达减速带时的时间，然后从噪声数据库中获取与通过减速带时的噪声数据并在车辆通过减速带时时播放反相噪声信号，从而达到主动降噪的效果。In some embodiments of the present invention, the obstacle information includes pedestrians, animals, speed bumps, and the like. Obstacles include objects about to collide with or around the vehicle that impede the vehicle's progress. For example, when there is a speed bump in front of the vehicle, Starlink can calculate the distance between the vehicle and the speed bump in front and the time to reach the speed bump, and then obtain the noise data from the noise database and pass the speed bump and when the vehicle passes The speed bump will play the anti-phase noise signal from time to time, so as to achieve the effect of active noise reduction.
在本发明的一些实施例中，环境信息包括风场信息以及降雨信息等，将风场信息和降雨信息上传到星链系统中，可以进一步提高计算车辆周围声场声压的精度，为后续的降噪措施提供前提条件，使得车辆的降噪效果更好。In some embodiments of the present invention, the environmental information includes wind field information and rainfall information, etc. Uploading the wind field information and rainfall information to the Starlink system can further improve the accuracy of calculating the sound pressure of the sound field around the vehicle, which is the basis for subsequent reductions. Noise measures provide preconditions to make the noise reduction effect of the vehicle better.
根据本发明的一些实施例，车辆可以根据声场声压信息来改变车辆的表面结构来实现降噪。也就是说，通过星链系统找出产生噪声的主要原因，然后针对该主要原因改变车辆的表面结构来实现降噪，该降噪方法主要针对噪声源单一的情况。According to some embodiments of the present invention, the vehicle may change the surface structure of the vehicle according to the sound field sound pressure information to achieve noise reduction. That is to say, the main cause of noise is found out through the Starlink system, and then the surface structure of the vehicle is changed to achieve noise reduction. This noise reduction method is mainly aimed at the case of a single noise source.
在本发明的另一些实施例中，车辆根据声场声压信息发生反相声波来进行主动降噪。从而正相声波与反相声波叠加，来实现主动降噪，该降噪方式可以应对噪声源为多个的情况。In other embodiments of the present invention, the vehicle generates anti-phase sound waves according to the sound pressure information of the sound field to perform active noise reduction. Therefore, the normal phase sound wave and the reverse phase sound wave are superimposed to realize active noise reduction, and this noise reduction method can cope with the situation where there are multiple noise sources.
进一步地，本发明的降噪方法还包括：获取车辆与障碍物之间的距离并计算车辆与障碍物碰撞的时间，从预设的噪声数据库中获取相应的噪声数据并在车辆与障碍物相碰时播放反相噪声信号。Further, the noise reduction method of the present invention further comprises: obtaining the distance between the vehicle and the obstacle and calculating the collision time between the vehicle and the obstacle, obtaining the corresponding noise data from a preset noise database and comparing the distance between the vehicle and the obstacle. Plays an inverted noise signal when it hits.
当汽车行驶时，采集汽车前方路面的实时图像，并识别获得前方路面存在的障碍物；在识别获得前方路面存在障碍物时，对该障碍物进行测距，测量获得汽车与障碍物之间的距离；获取汽车的实时行驶数据后，计算获得车轮与障碍物接触撞击产生噪声的时间信息，并从预设的噪声数据库读取相应的噪声数据；根据读取的噪声数据，生成对应的反相噪声信号；根据时间信息，在车轮行驶至障碍物处并与障碍物接触撞击时，在汽车底部播放该反相噪声信号，从而达到主动降噪的目的。When the car is driving, a real-time image of the road in front of the car is collected, and the obstacles existing on the road ahead are identified; when it is recognized that there is an obstacle on the road ahead, the obstacle is measured and the distance between the car and the obstacle is measured. distance; after obtaining the real-time driving data of the car, calculate and obtain the time information of the noise generated by the collision between the wheel and the obstacle, and read the corresponding noise data from the preset noise database; according to the read noise data, generate the corresponding inverse phase Noise signal; according to the time information, when the wheel travels to the obstacle and collides with the obstacle, the anti-phase noise signal is played at the bottom of the car, so as to achieve the purpose of active noise reduction.
需要说明的是，本发明中的道路信息、车辆信息、附近车辆信息、障碍物信息等可以通过导航系统(例如，北斗导航系统)获取并上传到星链系统。环境信息，例如风场信息以及降雨信息等可以有气象云平台上传到星链系统。星链系统将接收到的车辆的参数信息和周围环境参数，通过量子计算，得到车辆周围的实时噪声声压，即可得到风噪、雨滴噪声、障碍物撞击时噪声等实时噪声声压信息。It should be noted that the road information, vehicle information, nearby vehicle information, obstacle information, etc. in the present invention can be obtained through a navigation system (eg, Beidou navigation system) and uploaded to the Starlink system. Environmental information, such as wind field information and rainfall information, can be uploaded to the Starlink system through the meteorological cloud platform. The Starlink system uses the received vehicle parameter information and surrounding environment parameters to obtain real-time noise and sound pressure around the vehicle through quantum computing, and can obtain real-time noise and sound pressure information such as wind noise, raindrop noise, and noise when obstacles hit.
