System for detecting the intention of a user to open a hatch of a vehicle

An identifier for a vehicle, the identifier being configured to interact with an electronic control unit, the identifier comprising means for recording intention to open a hatch and being configured to:

• authenticate itself with the electronic control unit, the latter being integrated in the vehicle,
• when it is located in a region of proximity around a hatch of the vehicle, receive from the electronic control unit a request for confirmation of intention to open a hatch,
• following receipt of the request for confirmation of intention to open a hatch, verify a command confirming intention to open a hatch is stored in a memory in the identifier,
• if the command confirming intention to open a hatch is stored, send to the electronic control unit a command signal corresponding to the command confirming intention to open a hatch,
• if the command is not stored, send a data signal to a user of the identifier to initiate the command confirming intention to open a hatch via the means for recording intention to open a hatch,
• when the command confirming intention to open a hatch is initiated, send to the electronic control unit a command signal corresponding to the command confirming intention to open a hatch.

An electronic control unit configured to interact with an identifier, the electronic control unit being integrated in a vehicle and being configured to:

• authenticate the identifier,
• locate the identifier in region of proximity around a hatch of the vehicle,
• when the identifier is located in the region of proximity around the hatch, send to the identifier a request for confirmation of intention to open a hatch,
• if a command confirming intention to open a hatch is verified by the identifier as being stored in a memory in the identifier, receive from the identifier a command signal relating to a command confirming intention to open a hatch, and
• if the command is not stored, receive from the identifier a command signal corresponding to a command confirming intention to open a hatch if a user initiates the command confirming intention to open a hatch via a means for recording intention to open a hatch.

A method for detecting an intention of a user to open a hatch of a vehicle, the vehicle comprising an electronic control unit configured to interact with an identifier, the detecting method comprising:

• the electronic control unit authenticating the identifier,
• the electronic control unit locating the identifier in a region of proximity around the hatch,
• when the identifier is located in the region of proximity around the hatch, the electronic control unit sending to the identifier a request for confirmation of intention to open a hatch and the identifier receiving the request for confirmation of intention to open a hatch,
• on receipt of the request for confirmation of intention to open a hatch, the identifier verifying a command confirming intention to open a hatch is stored in a memory in the identifier and, if the command is stored, sending to the electronic control unit a corresponding command signal to open a hatch,
• if the command is not stored, the identifier sending a data signal to a user of the identifier to initiate the command confirming intention to open a hatch via the means for recording intention to open a hatch,
• when the command confirming intention to open a batch is initiated, the identifier sending to the electronic control unit a command signal corresponding to the command confirming intention to open a hatch,
• the electronic control unit receiving the command signal.
