20080211625 | METHOD FOR TEMPORARILY INHIBITING, WHEN IT HAS BEEN DETECTED INSIDE A LOCKED VEHICLE, A PORTABLE REMOTE CONTROL UNIT KNOWN AS A TAG BELONGING TO A KEYLESS ENTRY DEVICE - A method for temporarily inhibiting, when it is detected inside a locked vehicle, a portable remote control unit, known as a tag, of a keyless entry device designed to implement access authorization procedures to allow access to the vehicle, these including an initial identification procedure which includes causing a central processing unit to periodically transmit a data frame incorporating a preamble consisting of a predefined wake-up code that can be identified by the tag. The inhibition method include defining a first wake-up code at least intended for the procedure of temporarily inhibiting the tags, and a second wake-up code specifically intended for the procedure of identifying the tags, and in setting up temporary inhibition procedures which consist in causing a specific data frame incorporating, in its preamble, the first wake-up code and designed to deactivate the recognition, by each target tag, of the second wake-up code, to be transmitted. | 09-04-2008 |
