Zusammenfassung: | The signal exchange takes place between electronic appts. in a car. For reverse call from several control appts. forming slaves (2,3) to a master control appts. (1) the corresp. signal lines (5,7) are coupled to a logic wired AND circuit at a junction point (8). In addition the reverse call pulse trains are synchronised at their start flanks with the start flanks of the master control appts. By the selection of the digital logic (or/and) the largest or smallest of the value transmitted by the slave control appts. becomes effective at the side of the master control appts. USE/ADVANTAGE - For transmission of car engine parameters to control appts. with simple reverse call from slave control appts. to master. |
