Definitions

• the present invention relates to improvements to the so-called wireless "hands-free" kits of a motor vehicle. More particularly, it concerns the technical field of new uses of these systems.
• the hands-free kit is a highly recommended accessory for making phone calls by car, because of the prohibition on drivers using a hand-held phone in circulation.
• As an accessory it consists of a loudspeaker and a microphone.
• In original equipment it consists of a microphone and interfaces with the audio system of the vehicle, these facilities to keep both hands on the wheel during a telephone call.
• Bluetooth® technology has revolutionized this hands-free kit concept by providing a seamless and wireless connection between the driver's phone and the car kit: the so-called “wireless handsfree” integrate the reception of telephony on the loudspeakers of the motor vehicle.
• the hands-free kit - which can also be called KML in the rest of the text - automatically recognizes the mobile phone of the driver and connects it. It realizes a hands-free management of phone calls by car. It is enough for the driver to say the phone number, out loud, of the person to contact and the KML dials his number. And if the number of the correspondent is already registered in a telephone address book, it is enough for the driver to pronounce his name.
• An information screen at eye level for example on the dashboard or near the mirror, allows to see the identity of the caller.
• the French patent application No. 2868 235 there is a device for reading the files.
• compressed digital media such as Mp3, JPEG, DivX or others
• This device comprises a multimedia player and a Bluetooth® type radio module.
• the incoming telephone call can be switched to the device via the Bluetooth® radio link.
• the device has various functions. Two or more such devices can communicate with each other.
• the device can also make calls, record multimedia files, have FM radio function, have the clock function.
• Such a device is an autonomous, non-automotive device. It can not fit into an existing automotive system with a multifunction display (EMF) and radio. In other words, this device, if it can be installed in a motor vehicle, can only be completely autonomous, without reuse of existing automotive equipment, such as radio, speakers, screen, command under wheel. In addition, this device does not have the functionality of managing mobile wireless equipment (telephone, audio player, "Smartphone”), ie the possibility of changing, from the system to the nomadic equipment, to audio track, pause, trigger a fast forward or rewind, etc.

• Another object of the present invention is to design an improved wireless hands-free kit system, which includes additional functionalities for managing and controlling nomadic audio equipment.
• Another object of the present invention is to design an improved wireless handsfree kit system, which includes additional features relating to the sound reproduction of the vehicle sound sources on nomadic audio playback equipment.
• the invention proposes a new and improved wireless hands-free kit system, in which the wireless hands-free kit serves as a gateway between the vehicle's multimedia devices and nomadic audio equipment. .
• the nomadic equipment has transmitting functions and the multimedia equipments of the vehicle receiving functions.
• These mobile devices can be a wireless phone, connected to the wireless "handsfree" kit via a wireless link.
• These devices can also be, in addition to the wireless phone or separately, a wireless audio source, connected to the wireless "handsfree" kit via a wireless link.
• the wireless hands-free kit is then coupled to a sound management device, a graphic rendering member and the steering wheel control member.
• the "playlists" (or groupings of pre-selected pieces), all or part of the information relating to the pieces (duration, title, name of the artist, etc.) and the elapsed time of the wireless audio source are displayed on the vehicle's graphic rendering device.
• the sound reproduction of audio transmissions of nomadic equipment is performed by the sound management member on the speakers of the vehicle.
• the nomadic equipment has restitution functions and the vehicle equipment transmitting functions.
• the advanced wireless hands-free kit system then makes it possible to listen to the sound sources of the vehicle on said nomadic restitution equipment.
• These nomadic restitution equipment can include a wireless headset connected by a wireless link to the "hands-free" kit.
• These devices can also be, in addition to the wireless headset or separately, a wireless phone connected by a wireless link to the hands-free kit.
• the control of nomadic equipment can be achieved using the controls under the steering wheel and / or the controls of the radio of the vehicle.
• a vehicle display screen can display information on the status of nomadic restitution equipment.
• the wireless headset may be equipped with a specific automotive Human Machine Interface (HMI), which may be a push button for selecting the sound source of the vehicle that the user wishes to listen to: radio, CD, DVD, telephone vehicle, etc.
• HMI Human Machine Interface
• the wireless links of nomadic playback equipment with the "hands-free" kit can be wireless Bluetooth® type links, or UWB type wireless links.
• the sound management unit can be one or more of the following organs: radio, automobile radionavigation, high fidelity amplifier.
• the graphic rendering member for displaying windows dedicated to the telephony function is one or more of the following organs: multifunction screen, navigation screen.

• the vehicle display screen to display information on the status of the mobile equipment (active or not, source used, etc.)
• each wireless headset 10 it is possible to equip each wireless headset 10 with a specific automotive Human Machine Interface (HMI), for example a push button, which makes it possible to choose the sound source of the vehicle that the user wishes to listen to: radio, CD, DVD, vehicle phone, etc.
• HMI Human Machine Interface
• Each key press makes it possible to send a command to the wireless hands-free kit 1, which then sends the information on the vehicle network 7 to the right recipient.
• the present invention has many advantageous results. On the one hand, it allows to reuse the existing wireless handsfree kit device by considering it as a bridge between the existing equipment of the vehicle (radio, screen, command under steering wheel) and nomadic equipment (cordless phone , wireless sound sources, etc.).
• This enhancement to the wireless hands-free car kit also offers the advantage of making it easier to build a range of customer services ("hands free” kit, listening nomadic audio, differentiated audio listening conductor / passengers, etc.) at a lower cost since the organ exists. It is therefore not necessary to carry out a complete development of this "wireless gateway".
