Abstract

A vehicle system includes a hands-free phone module. The hands-free phone module may be configured to wireless connect with a cellular phone to enable the vehicle's audio system to be used as a part of the hands-free phone. The volume of the outputs (voice, ringer, etc.) may be adjusted to compensate for increasing ambient noise in the vehicle. Volume may be adjusted based on an increase in vehicle speed, a change in tire pressure of the vehicle's tires, an increase in ambient noise, a combination of these factors, or some other factor or combination of factors. Ambient noise and voice inputs from a user may be received by a common microphone. The volume adjustments may take place in the hands-free module, in the vehicle audio system, and/or in the portable phone itself.

Description of Innovation

Background

    New vehicle systems are being introduced into the market to allow consumers to have hands free phone operation while in the vehicle. It allows the consumer's mobile phone to link to the vehicle audio system and includes a microphone in the vehicle for high quality hands free phone operation. See Diagram 1 (attached). This hands-free operation may be facilitated by a wireless link (such as using a BluetoothTM link) from the phone to the vehicle audio system. One problem is the ringer and the phone audio which are transmitted through the vehicle speakers are difficult to hear as the vehicle speed increases and the ambient noise level in the vehicle increases.

Description

    A vehicle phone system 8 includes a hands-free phone module 10 which communicates with a cellular phone 24 by way of a wireless link 22. Hands-free phone module 10 is connected to a vehicle audio system 16 and is configured to transfer audio data 20 from wireless phone 24 to vehicle audio system 16 to be output by speakers 14. Hands-free phone module 10 may also be configured to mute 18 other audio data from vehicle audio system 16 so that speakers 14 only output sound representative of phone audio data 20. hands-free phone module 10 may also include a microphone 12 for receiving user audio inputs. Hands-free phone module 10 may be configured to transfer data based on the user audio inputs to cellular phone 24 by way of wireless link 22. Hands-free phone module 10 may also be configured to receive a wired phone input.

    Hands free phone module 10 may have access to information on the vehicle's data bus. Hands-free phone module 10 may receive d...
