Playing method of sound control vehicular player

Abstract

The invention discloses a playing method of a sound control vehicular player. First of all, a parallel table of player control driving signals and entry codes is established; then, a database of sound instruction sample characteristic values and the entry codes is established; next, a BP network model is established, the BP network model is enabled to input the sound instruction sample characteristic values and output the entry codes, data in the database of the sound instruction sample characteristic values and the entry codes is input into the BP network model, and the BP network model is trained until network errors of the BP network model are smaller than and equal to a preset error threshold; and during work, a voice instruction of a driver is acquired, after the voice instruction of the driver is preprocessed, a characteristic value is calculated and then input to the BP network model, a corresponding entry code is obtained, retrieval is carried out in the parallel table, and a corresponding driving control signal is found for driving a player to work. According to the invention, the application is convenient, the driver does not have to move for operating the player, and thus the driving safety is improved.

Problems solved by technology

[0012] Existing car players generally require manual control, such as switching, FM and CD switching, sound adjustment, song switching, etc. Since driving requires a high degree of concentration, it is inevitable to be distracted when performing these operations manually. Check the player status, etc., which can easily cause traffic accidents
