Circuit module for interconnection between local networks in a distributed electronic system for motor vehicles.

摘要

A module (I) circuit for interconnection between local networks (CAN, LIN) of an electronic control system on board motor vehicles to control func- tions of the passenger compartment and ceria carro-, the system comprising: a plurality of electronic units (M) connected control each other by means of at least one main network (CAN) serial communication using a first proto- colo transmission, and a plurality of circuits (S) for actuating provi- tive board, connected to a mode of the main network (CAN) by means of at least one peripheral network (LIN) communica- tion in series in which they act as nails is- nodes, using said circuits (S) one the second transmission protocols in which the module (I) circuit is arranged to interconnect the peripheral network (LIN) serial communication and the main network (CAN) serial communication, acting as a pri network node ncipal (CAN) and as the master of the peripheral network (LIN) node, and comprise an electronic processing unit adapted to control signal conversion between signals bitstreams (FCAN, FLIN) relating to the first and second transmission protocols to enable data transfer between units (M) control and driver circuits (S), is- Tando unit arranged to divide the bit string (FCAN; FLIN) of a signal received from one (CAN network; LIN) into a plurality of elements (fi) of information and to assemble a plurality of elements (fi ') information in a signal chain different bits (FLIN; FCAN ) for transmission to the other network (LIN; CAN).
