Abstract

A flexible wiring system for an electronic system includes a basic control circuit for controlling specific control circuits to obtain data from a sensor, a communication bus connected with the basic control circuit and the specific control circuits, and an intermediate distributing unit. The intermediate distributing unit includes plural first side connectors connectable with the basic control circuit and the specific control circuits, plural second side connectors connectable with sensors and actuators. The basic control circuit communicates signals with the specific control circuits via the communication bus so that the specific control circuits can control corresponding actuators according to the data obtained from corresponding sensors via the intermediate distributing unit.

Claims

1.
