<p><P>PROBLEM TO BE SOLVED: To provide a control system in which a plurality of control devices for controlling respectively a plurality of objects to be controlled are connected bus-like to send/receive a signal with low power consumption, and to provide a control device used for the control system with the low power consumption. <P>SOLUTION: When an object to be controlled by ECU 3a, 3b, 3c, 3d, 3e, 3f, 3g and 3h is caused to carry out a specific operation, an ECU 2 selects an ECU having a microcomputer to which electric power is supplied, from among the ECU 3a, 3b, 3c, 3d, 3e, 3f, 3g and 3h. The ECU 2 forms device information showing the selected ECU and outputs the signal including the formed device information to a communication line 4. Each of the ECU 3a, 3b, 3d, 3e, 3f, 3g and 3h receives the signal including the device information, uses the device information included in the received signal to determine whether the power is supplied or not to own microcomputer, and when determining that the power is supplied, the ECU 2 permits power supply from a battery to the microcomputer. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
