Embodiment Construction

[0026] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0027] Such as figure 1 As shown, the figure is a schematic diagram of the vehicle active control sound enhancement system.

[0028] Ways for cars to actively control sound enhancement include:

[0029] 1. Detect the active controller switch, if the switch is turned on, read the engine speed from the CAN bus;

[0030] 2. The on-board entertainment host will automatically generate the controller file and provide the customer with a menu to select the sound file;

[0031] 3. Read the number of the sound file selected by the passenger, and call the corresponding engine sound file;

[0032] 4. Combining the engine speed and the engine sound file, calculate the gain coefficient Kp of the sound playback interval;

[0033] Among them, Rmin is the min...

Abstract

The invention discloses a method and system for automobile actively controlling sound enhancement. The method comprises the following steps that 1, an active generation controller receives the enginerotation speed in the CAN network communication of an automobile, an active noise reduction control system is started, and control initialization is finished; 2, an entertainment host provides a listof pre-stored engine sound files, and a passenger can freely select the engine sound files; 3, the active generation controller receives a selection item of the passenger, reads the engine speed froma CAN bus, calculates the sound gain and play interval corresponding to the engine speed in real time, and matches the sound file with the automobile acceleration; and 4, the active generation controller multiplies the sound data to be played by the gain and outputs to a DA and removes the output sound of automobile loudspeakers so as to provide a sound experience for the passenger. The method provides passengers with the multiple engine sounds freely selected, realizes the conversion of different engine enhanced sounds in the automobile through an active sound control system, and greatly improves the engine auditory effect felt by the passenger.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for actively controlling sound enhancement of automobiles. Background technique [0002] As the car is one of the necessary means of transportation in people's life, more and more attention is paid to the sound experience that the car brings to passengers. In the industry, some research and development related to engine sound control focuses on active noise reduction to provide passengers with a quiet and comfortable riding environment, and more and more car owners, especially young car owners, are interested in the powerful sound and sound quality brought by the engine. Texture is becoming more and more demanding. [0003] The current car sound control is mainly noise reduction in the car. For example, the announcement number is CN106089361A, and the announcement date is 2016.11.09. The announcement number is CN205652027U, and the announcement date is 2...
