Wake-up system for stations associated for implementing at least a distributed function, in particular in a motor vehicle

摘要

The invention concerns a wake-up system of stations connected to a data transmission network (37) in particular for a motor vehicle, wherein the stations (31, 32, 33, 34, 35, 36) must shift from a standby or off state to a wake-up state to exchange data concerning the distributed function. The invention is characterized in that all the stations are connected by a single line (38) transmitting a station wake-up signal, and at least some of said stations comprise means (39) for generating a wake-up signal on said line (38) to cause the other stations to shift into their wake-up state and means (40) for transmitting data concerning the distributed function, over the data transmission network, and at least some of said stations comprise means (40) for analyzing said data over the data transmission network to determine whether they are concerned thereby and hence by the corresponding distributed function, so as to remain in wake-up state or to shift into standby or off state otherwise.
