System and method for receiving audible input in a vehicle
First Claim
1. A steering wheel system for a vehicle, comprising:
- a first microphone mounted in a steering wheel;
a second microphone mounted in the vehicle, the first and second microphones each configured to receive an audible input, the audible input comprising an oral command component and a noise component; and
a controller configured to identify the noise component by determining that the noise component received at the first microphone is out of phase with the noise component received at the second microphone, the controller configured to cancel the noise component from the audible input.

Abstract
A steering wheel system for a vehicle. The steering wheel system includes a first microphone mounted in a steering wheel and a second microphone mounted in the vehicle. The first and second microphones are each configured to receive an audible input. The audible input includes an oral command component and a noise component. The steering wheel system also includes a controller configured to identify the noise component by determining that the noise component received at the first microphone is out of phase with the noise component received at the second microphone. The controller is configured to cancel the noise component from the audible input.

10. A method for canceling noise received from an audible input received by a vehicle system configured to receive oral commands, the vehicle system including a first microphone, a second microphone, and a controller, the method comprising the steps of:
-
receiving the audible input at the first microphone; receiving the audible input at the second microphone, the audible input comprising an oral command component and a noise component; identifying the noise component using the controller by determining that the phase of the noise component received at the first microphone is different than the phase of the noise component received at the second microphone; and canceling the noise component from the audible input using the controller. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
