Device and method for automobile voice control and automobile

Abstract

The invention discloses a device and a method for automobile voice control and an automobile and belongs to the automobile field. The device comprises an acquisition noise reduction module used for acquiring a simulation audio signal in the automobile, carrying out analog-to-digital conversion of the signal and noise reduction processing to acquire a digital audio signal and sending the digital audio signal to a signal conversion module, the signal conversion module used for receiving the digital audio signal sent by the acquisition noise reduction module, converting the signal into an automobile audio bus signal and sending the automobile audio bus signal through an automobile audio bus interface to an identification control module, and the identification control module used for identifying the automobile audio bus signal sent by the signal conversion module and performing corresponding control operation according to the identification result. The device is advantaged in that high fidelity of the audio signal and audio transmission timeliness are guaranteed, vehicle wiring complexity is reduced, and weight of a transmission cable bunch is further reduced.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a voice control device and method for automobiles and the automobile. Background technique [0002] Along with the development of society, automobile has become a kind of important means of transportation in people's life. With the further development of the automobile industry, in order to facilitate the driver's operation of the vehicle navigation system and the vehicle entertainment system and other systems, voice recognition technology has been applied in more and more vehicles. [0003] At present, in existing cars, the on-board voice recognition system only has a fixed analog microphone at the driver's position, and the audio signal is output by analog signal, and in terms of wiring, traditional analog audio signal lines are used. In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the directional...

AI Technical Summary

Problems solved by technology

In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: the directional analog microphone can only amplify and collect audio signals, but cannot perform noise reduction processing in the vehicle environment; and the output of audio analog signals is easily disturbed , the signal quality of the output audio cannot be guaranteed; at the same time, because the transmission of audio analog signals uses traditional audio signal lines, the wiring method is very complicated, and the weight and cost of the wiring harness are increased.
