A system for the controlled exclusion of branches of a serial communication network in an electronic control system for onboard devices of motor vehicles
摘要：
A control system comprises at least one electronic control unit (10) intended to manage the passenger compartment and/or vehicle body functions, which can be connected to a plurality of driving circuit modules (14-17) for driving on board devices through a serial communication network (12), in which the driving modules (14-17) of the on board devices are each connected through a respective peripheral communication branch (24-26) to a common node of the network (12), and to the control unit (10) through a single main physical communication line (20).
An interface circuit (35) is interposed between the main communication line (20) and the branches (24-26) of the network (12) at the common node, and includes a plurality of controlled switching devices (40) corresponding in number to the number of branches (24-26) of the network (12), and is operable selectively to interrupt connection of one or more peripheral communication branches (24-26) to the main communication line (20).
摘要（中）：

一种控制系统，包括用于管理乘客室和/或车体的功能，其可以被连接到驱动电路模块（14-17）的多个用于通过串行驱动船上设备的至少一个电子控制单元（10） 通信网络（12），其中，所述车载设备的驱动模块（14-17）各自通过一个respectivement外围通信分支（24-26）到网络（12）的公共节点连接，并且所述控制 单元（10）通过单个主物理通信线路（20）。 接口电路（35）插置在主通信线路（20），并且在公共节点的网络（12）的分支（24-26）之间，并且包括受控开关器件在数目对应于多个（40） 网络（12）的分支（24-26）的数量，并且可操作选择性地中断到主通信线路（20）中的一个或多个外围通信分支（24-26）连接。
