Abstract

Wireless RF technology, for example, Bluetooth®, WiFi, etc. is used to transmit signals between electronic systems and devices in a vehicle. User speech sensed by an in-vehicle microphone may be transferred wirelessly to a remotely located electronic vehicle system/device in the vehicle such as a hands free telephone system, a memo recorder, a radio head unit, a navigation system, etc., using a wireless communication technology. Wireless technology may also be used to communicate signals representing user tactile interactions such as through buttons, switches, dials, knobs, etc., of a user interface in the vehicle to a remotely located vehicle system/device, for example, a hands free telephone system, power door locks, seat controllers, power windows, etc. In addition, audio data and/or audio control/negotiation data may be transmitted from a remote electronic vehicle system/device to an in-vehicle audio system using a wireless communication technology.

WIRELESS-ENABLED MICROPHONE, SPEAKER AND USER INTERFACE FOR A VEHICLE

Abstract

Wireless RF technology, for example, Bluetooth®, WiFi, etc. is used to transmit signals between electronic systems and devices in a vehicle.  User speech sensed by an in-vehicle microphone may be transferred wirelessly to a remotely located electronic vehicle system/device in the vehicle such as a hands free telephone system, a memo recorder, a radio head unit, a navigation system, etc., using a wireless communication technology.  Wireless technology may also be used to communicate signals representing user tactile interactions such as through buttons, switches, dials, knobs, etc., of a user interface in the vehicle to a remotely located vehicle system/device, for example, a hands free telephone system, power door locks, seat controllers, power windows, etc.  In addition, audio data and/or audio control/negotiation data may be transmitted from a remote electronic vehicle system/device to an in-vehicle audio system using a wireless communication technology. 

Description of Innovation

Vehicles may include a number of electronic systems and devices such as an audio system (e.g., a radio, speakers, CD player, MP3 player), a microphone, a hands free telephone system, a navigation system, power door locks, power windows, power seats, user interfaces (e.g., buttons, switches, knobs, dials) for command/control of such devices, etc.  Often, such systems communicate between one another.  Typically, communication between such systems and devices is done via signals sent over wired connections in the vehicle.  Since these devices may be located throughout the vehicle, design and management of the wiring may be difficult and the cost of the wiring may be expensive.

The innovation is the use of wireless RF technology (e.g., Bluetooth®, WiFi, etc.) to transmit signals (e.g., audio signals, command/control signals, etc.) between various electronic systems or devices in a vehicle.  Figure 1 is a block diagram of one embodiment of the innovation.  Wireless RF technology (e.g., Bluetooth®, WiFi, etc.) may be used to transmit audio from a microphone 20 located in a vehicle (e.g., an automobile, minivan, sport utility vehicle, etc.) to a remotely located electronic vehicle system/device 30.  Microphone 20 is mounted or integrated in the vehicle, for example, in an overhead console, headliner, etc.  A user interface 10 comprising, for example, buttons, switches, knobs, dials, etc. may be co-located with microphone 20 or located elsewhere in the vehicle.  Electronic vehicle system/device 30 may be a speech enabled device, such as, a hands free telephone system control module, a memo recorder, a radio head unit, a navigation system, etc.  A hands-free telephone system control module may also be configured to communicate with a vehicle occupant’s cellular phone (not shown) via a wireless communication link, e.g., a Bluetooth® communication link.
