Abstract
A device for improving the security of a “hands-free” access system for a motor vehicle, the system comprising an identification device installed on the vehicle and able to control the locking the opening leaves of the vehicle, and at least one identifier intended to be worn or carried by a user and capable of setting up a remote exchange of data with the identification device so as to control the locking means, when the identification device has authenticated the identifier, the identification means being intended, after a locking command, to send an interrogation signal into the cabin of the vehicle and receive in response a “present” signal from each identifier still present in the cabin, wherein, when a “present” signal is received by the identification device, the identification device sends into the cabin an inhibit signal which is received and stored in memory by each identifier present in the cabin.
