Patent ID: 8791808

Claim:
A method for wireless communication between a control unit ( 11 ), such as a central unit integrated into a vehicle or an external diagnostic tool manipulated by an interlocutor, and an electronic housing mounted on a vehicle member, said method consisting: in transmitting information to the electronic housing ( 6 - 9 ) in the form either of continuous signals consisting of a carrier wave, or of signals modulated by data forming an encoded message, and in configuring the electronic housing ( 6 - 9 ) so that it possesses, on the one hand, two reception modes dedicated respectively, one to the detection of continuous signals consisting of a specific carrier wave, and the other to the detection of signals modulated by data, and, on the other hand, a strategy of switching between said reception modes, said communication method being characterized in that the strategy for switching over between the two reception modes consists: in establishing a permanent standby state in which the electronic housing ( 6 - 9 ) is set to its continuous signals reception mode, and, during the reception of a continuous signal: in controlling a switchover to the modulated signals reception mode for a predetermined maximum time period T during which the electronic housing ( 6 - 9 ) is programmed to process the data of the potential detected modulated signal, and at the end of which and in the absence of detection of a modulated signal during this period T, the electronic housing ( 6 - 9 ) is programmed to process the reception of the continuous signal at the origin of the switchover, and after processing of the modulated signal or of the continuous signal, in switching over to the permanent standby state, in which the electronic housing ( 6 - 9 ) is set to its continuous signals reception mode.
