초록 ▼

This invention relates to a control system for controlling equipment provided inside a vehicle utilizing a speech recognition apparatus inside the vehicle. This control system includes an in-phase component detector (4) for detecting an in-phase component of voice signals from microphones (1), a phase shift and in-phase component detector (5) for shifting a phase of the voice signals to detect an in-phase component, and a command seat discriminator (6) for comparing output levels of the in-phase component detector (4) and the phase shift and in-phase component detector (5). In addition, the control system includes validity/invalidity detector (7) for determining the validity and invalidity of a command content resulting from outputs of a speech recognizer (3) based upon a signal generated from the command seat discriminator (6), and a various controller (8) that controls any one of various pieces of equipment with respect to the valid commands output from the validity/invalidity detector (7) to reliably discriminate commands from the driver\s seat and the passenger seats in a noisy vehicle.

대표청구항 ▼

A control system controlling vehicle equipment provided inside a vehicle utilizing a speech recognition apparatus having microphones installed inside the vehicle and speech recognition means for recognizing a voice command having a command content transmitted from the microphones controlling the vehicle equipment including one of audio, air conditioning, telecommunication, navigation and vehicle control equipment installed inside the vehicle and outputting a speech signal responsive to the voice command, said control system comprising: first means including in-phase component detecting means for detecting a first in-phase component having a first output level of voice signals including the voice command for operating the vehicle equipment and transmitted by the microphone positioned symmetrically with respect to a driver seat, and said first means for determining that the voice command is generated at said driver seat; second means including phase shift and in-phase component detecting means for shifting a first phase transmitted by one of the microphones generating a first shifted signal, and a second phase transmitted by another of the microphones generating a second shifted signal, and for generating a second in-phase component having a second output level using said first and second shifted signals for operating said vehicle equipment, said microphones being positioned asymmetrically with respect to passenger seats, and said second means for determining that the voice command is generated at said passenger seats; command seat discriminating means for comparing the first and second output levels to determine from which seat the voice command was generated among several seats, and for generating a command seat signal identifying the seat; and determining means for determining validity or invalidity of the command content using the speech signal output from the speech recognition means, the command seat signal output from said command seat discriminating means and predetermined criteria, and when the voice command is issued from said driver seat the voice command is valid, and when the voice command is issued from one of said passenger seats the voice command is valid or invalid based upon the predetermined criteria, and said control system controls the vehicle equipment when the voice command is valid.
