Connection system between a master and slave processing units.

摘要

A connection system of the multiplex type between at least one master processing unit (5) and slave units (27), in particular associated with electrical devices (14, 15, 17, 18, 28, 28 min , 32, 33) in a vehicle (1) for activating or controlling at least one electrically functioning component in the corresponding device (14, 15, 17, 15, 28, 28 min , 32, 33), the said slave units (27) being connected in groups to the master unit (5) by means of corresponding communication channels (11, 11 min , 11 sec ,...) common to the units (27) of each group, and in which the master unit (5) includes logical means (6) for controlling the exchange of communications between the various channels (11, 11 min , 11 sec ,...); in particular these logical means include a microprocessor (6) and control corresponding first blocks enabling transmission on such communication channels (11, 11 min , 11 sec ,...) and corresponding second blocks enabling communication between the abovementioned channels (11, 11 min , 11 sec ,...).
