“Hands-free” access and/or engine starting system for automobile vehicles
First Claim
1. Authentication device (1) for automobile vehicles (V1, V2) that controls door locking and/or engine starting and is able to interchange data over a certain distance with an identifier (3, 10-12), intended to be carried by a user, when said identifier lies within the emission/reception coverage zone of said authentication device, to enable control of a requested function including “
- hands-free”
vehicle access and/or engine starting by corresponding determined actions of a user on the vehicle, when said identifier has been authenticated by said authentication device,wherein said authentication device (1) is connected to a single antenna (2) inside the vehicle passenger compartment (H) and is able to emit via said antenna at least two distinct emission powers, a first emission power enabling said antenna to cover a first zone (Z1, Z′
1) including at least part of said passenger compartment (H), and a second emission power greater than said first emission power enabling said antenna to cover a second zone (Z2, Z′
2) including at least the whole of said passenger compartment and a coverage zone outside said vehicle, for proximity detection of the identifier by interrogation of a location of the identifier in or outside specific zones according to said user'"'"'s requested function and checking if the location of the identifier allows the requested function.

Abstract
The disclosure relates to an authentication device for automobile vehicles that controls door locking and/or engine starting and is able to interchange data over a certain distance with an identifier, intended to be carried by a user, when said identifier lies within the emission/reception coverage zone of said authentication device, to enable “hands-free” vehicle access and/or engine starting when said identifier has been authenticated by said authentication device, wherein said authentication device is connected to a single antenna inside the vehicle passenger compartment and is able to emit via said antenna at least two distinct emission powers, a first emission power enabling said antenna to cover a first zone including at least part of said passenger compartment, and a second emission power greater than said first emission power enabling said antenna to cover a second zone including at least the whole of said passenger compartment and possibly a coverage zone outside said vehicle.
