<p><P>PROBLEM TO BE SOLVED: To perform non-arc release and failure determination for a power supply system. <P>SOLUTION: The power suppl system 1000 comprises a SMR120; an MG inverter 130; a first MG140; a second MG142; a high-voltage power supply 160; a low-voltage power supply 170; an AC inverter 200; a HV_ECU100 which commands the MG inverter 130 to cut off the first MG140 and a second MG142 through a signal line 102, and commands to cut off the AC inverter 200 through a signal line 104 and then releases the SMR120; and an AC_ECU400 which makes a signal line 104 determine it as a trouble of GND circuit-shorting, if a state of the AC inverter 200 recognized based on a signal from the AC inverter 200 and a state of the AC inverter 200 are not matched each other. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
