Example Embodiment

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] see image 3 , the embodiment of the present invention includes a left front microphone 1, a right front microphone 2, a rear microphone 3, a voice control unit and the like. The left front microphone 1 and the right front microphone 2 are installed symmetrically about the longitudinal axis of the car, and the front right microphone 2 and the rear microphone 3 are installed symmetrically about the horizontal axis of the car.

[0046] The working principle of the present invention is described as follows:

[0047] see figure 1 , the left front microphone 1 , the right front microphone 2 , and the rear microphone 3 are installed and fixed, that is, the coordinate positions are known, but the sound source 4 is unknown. Although the position of the sound source is unknown, if the sound source 4 does not move, the distance differ...

Abstract

The invention provides a vehicle-mounted voice control method and system based on sound source positioning. The position of a voice source in a vehicle is judged through a time difference method according to the competitiveness of voice commands of drivers and passengers in the vehicle, whether execution is carried out or not is selected according to setting, the driving safety performance is guaranteed, meanwhile, the man-machine interaction function and scene are enriched, the function that the designated person controls the designated vehicle is achieved, and the safety of vehicle use is improved. The voice command users including the main driver, the co-driver and the back row passengers are customized, the choices are diversified, and the use is flexible. The method is simple in example, does not need complex operation, and improves the response sensitivity. According to the invention, free switching of functions can be realized, the functions of the vehicle-mounted terminal are enriched, and the advanced sense is improved. The device is simple in structure and low in cost.

Description

technical field [0001] The invention belongs to the technical field of sound source localization, and in particular relates to a vehicle voice control method and system based on sound source localization. Background technique [0002] As the concepts of autonomous driving and smart cockpit become more and more popular and voices are getting higher and higher, the requirements for on-board equipment are getting higher and higher, not only need to realize the function, but also need to refine the function. At present, the vehicle-mounted IVI on the market can already realize the basic voice interaction function, which is convenient for the driver and passengers to a certain extent, but the current product does not judge the source of the voice, that is to say, no matter who it is, as long as the voice command is issued, The system will automatically execute related functions, the functions are relatively single, and it is safer for some voice commands related to driving safety...
