1. An on-vehicle acoustic control system comprising:
- on-vehicle devices including at least one of on-vehicle ECUs and on-vehicle systems that output a command representative of a request to output sound data and the sound data to a sound management ECU;
means for outputting a sound;
means for analyzing a command, when the command is inputted from the on-vehicle devices, to determine priority of the sound data, and when the sound data is inputted from the on-vehicle devices, outputs a sound corresponding to the inputted sound data in an order of the priority of the sound data; and
an Al agent that selectively executes a user mode and a vehicle mode, wherein the user mode detects a user'"'"'s physical condition, and the vehicle mode outputs from the outputting means a sound corresponding to the sound data outputted to the analyzing means from the on-vehicle devices,wherein, when executing the vehicle mode, the Al agent acoustically controls at least one of volume, timing and speed of generation of sound for a sound corresponding to the sound data outputted to the analyzing means from the on-vehicle devices based on the user'"'"'s physical condition detected in the user mode thereby outputting the controlled sound from the outputting means;
whereinthe Al agent increases the volume of the sound and slows down the speed of generation of the sound when the physical condition of the user is determined to be poor.

Abstract
An on-vehicle acoustic control system determines which one of sounds of an audio device and a navigation device should be generated with priority, when both devices are requested to generate respective sounds. The control system further detects a user'"'"'s physical condition based on an interaction with the user, a picture of the user and biometric information of the user. The control system generates sound in the order of determined priority, and varies the manner of sound generation based on the user'"'"'s physical condition.

9. An acoustic control method for a vehicle having a plurality of sound generating devices, the method comprising steps of:
-
determining priority of sound generation of the sound generating devices when at least two sound generating devices are requested to generate respective sounds; detecting indirectly a physical condition of a user in a vehicle; and generating requested sound in the vehicle in an order of the priority determined by the determining step and in a manner variable with the physical condition of the user detected by the detecting step by controlling at least one of volume, timing and speed of generation of sound for the requested sound;
whereinthe sound generating devices include an audio device and a voice message generating device for providing information about a travel path of the vehicle; the determining step determines that the voice message generating device has a higher priority over the audio device; the generating step generates the voice message while reducing a volume of output sound of the audio device in a case that the voice message is requested while the audio device is in a sound generating operation; and the generating step increases a volume of the voice message and decreases a speed of the voice message when the detecting step detects that the user is tired. - View Dependent Claims (10)

11. A computer-readable memory having an Al agent recorded thereon, the Al agent being used in an on-vehicle acoustic control system comprising on-vehicle devices including at least one of on-vehicle ECUs and on-vehicle systems that output a command representative of a request to output sound data and the sound data to a sound management ECU, means for outputting a sound and means for analyzing a command inputted from the on-vehicle devices to determine the priority of the sound data, and outputs from the outputting means a sound corresponding to the sound data inputted from the on-vehicle devices based on the priority of the sound data,
wherein the Al agent, is programmed to selectively execute a user mode that detects a user'"'"'s physical condition and a vehicle mode that outputs from the outputting means a sound corresponding to the sound data outputted to the analyzing means from the on-vehicle devices; - and
acoustically control, when executing the vehicle mode, at least one of volume, timing and speed of generation of sound for a sound corresponding to the sound data outputted to the analyzing means from the on-vehicles devices based on the user'"'"'s physical condition detected in the user mode, thereby outputting a controlled sound from the outputting means;
whereinthe Al agent increases the volume of the sound and slows down the speed of generation of the sound when the physical condition of the user is determined to be poor. - View Dependent Claims (12)
