Architecture of a multimedia and hands-free phone equipment for a motor vehicle
First Claim
1. A multimedia and hands-free phone equipment for a motor vehicle, comprising:
- a) a pilot box (10), adapted to be removably attached to the vehicle dashboard, near the driver, comprising;
a signal processing and equipment control digital processor (18); and
, coupled to said processor;
an information display screen (20);
means for applying user commands; and
means (26) of wireless coupling with a remote phone (28),b) an offset box (12), distinct from the pilot box and adapted to be mounted in the vehicle, remote from the pilot box, and comprising;
an audio amplifier (52) adapted to be linked to a loud-speaker (54) located in the passenger compartment; and
a power supply (46), adapted to be linked to the vehicle electrical network (48), andc) a link (14) for coupling the pilot box to the service box, said equipment being characterized in that;
the coupling link is consisted of a bidirectional digital bus adapted to convey concurrently digital signals and power supply currents;
the pilot box further comprises an interface (32) coupling the processor to the digital bus; and
the offset box further comprises;
an audio codec (56) coupling the digital bus to the audio amplifier; and
an interconnection arrangement (38, 50, 58, 60, 64) for wire connection to a plurality of peripheral devices (40, 42, 44, 62, 68, 72) of the equipment, andthe power supply is adapted to supply (i) directly the offset box circuits, and (ii) indirectly, via the digital bus, the pilot box circuits.

Abstract
The equipment comprises a pilot box (10) mounted on the dashboard, an offset box (12) and a link (14) for coupling these boxes. The pilot box comprises a signal processing and equipment control digital processor (18) and, coupled to this processor, an information display screen (20), means for applying user commands, and means (26) of wireless coupling with a remote phone (28). The offset box (12) comprises an audio amplifier (52) and a power supply (46) linked to the vehicle electrical network (48). The coupling link is consisted of a bidirectional digital bus adapted to convey concurrently digital signals and power supply currents. The offset box comprises an audio codec (56) coupling the digital bus to the audio amplifier, and an interconnection arrangement (38, 50, 58, 60, 64) for the wire connection to a plurality of peripheral devices (40, 42, 44, 62, 68, 72) of the equipment.
