<P>PROBLEM TO BE SOLVED: To obtain a power supply control system for a vehicle capable of reducing consumption of power not by a hardware, but by a software. <P>SOLUTION: Information indicating whether an ECU 2 is under a security condition or not is transmitted from the ECU 2 to a power supply control ECU 3 via a channel 4. When the ECU 2 is under the security condition, the power supply control ECU 3 turns off an accessory switch (relay 11). The accessory switch is turned off, so that supply of a driving power from an ECU power source 10 to the ECU 2 is turned off. <P>COPYRIGHT: (C)2007,JPO&INPIT |
