Embodiment Construction

[0028] 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.

[0029] Such as figure 1 As shown, the figure is a schematic diagram of the vehicle active control sound enhancement system.

[0030] Ways for cars to actively control sound enhancement include:

[0031] (1) Detect the active sound controller switch, if the switch is turned on, read the engine speed from the CAN bus;

[0032] (2), the car entertainment host runs the active sound controller file, and provides the customer with a menu for selecting sound files;

[0033] (3), read the sound file number selected by the passenger, and call the corresponding engine sound file;

[0034] (4), in combination with the engine speed and the engine sound file, calculate the gain coefficient Kp of the sound playback interval;

[0035] Among them, Rmin is the...

Abstract

The invention discloses a method and system for actively controlling the sound enhancement of a car. The method is as follows: the active sound controller receives the engine speed in the vehicle CAN network communication, starts the active noise reduction control system, and completes the control initialization; the entertainment host provides pre-storage The list of engine sound files allows passengers to freely select engine sound files; the active sound controller receives the selection items of passengers, and combines the read engine speed to calculate the sound playback gain and sound playback interval corresponding to the engine speed in real time, and perform sound files Match the engine speed of the vehicle; the active sound controller multiplies the sound data to be played by the gain and outputs it to the DA and removes the output sound from the speakers on the car for passengers to experience the sound. The invention provides passengers with free choice of multiple engine sounds, realizes the conversion of different engine enhanced sounds in the vehicle through the active sound control system, and improves the engine auditory effect experienced by passengers.

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...
