摘要： PROBLEM TO BE SOLVED: To provide an electric power distribution system capable of reducing unnecessary dark current. SOLUTION: A master CPU (20a) does not immediately transmits an activation signal to a slave CPU (20b) even if it receives a predetermined instruction signal at off of an ignition switch. At this time, electric power required for an electronic control unit (8c) is fed to a converter (10) for feeding a stand-by current. The master CPU (20a) transmits an activation requirement signal to a controller (12) so as to activate an always feed converter (9). The controller (12) transmits an activation finishing signal to the master CPU (20a) after it activates the always feeding converter (9). The master CPU (20a) firstly transmits the activation signal to the slave CPU (20b) after it receives the activation finishing signal. Thereby, all electronic control units (8c-8f) are fed with the electric power from the always feeding converter (9). COPYRIGHT: (C)2006,JPO&NCIPI
