POWER SUPPLY SYSTEM FOR VEHICLE

摘要

A controller of a power supply system includes HV_ECU (320) and EPS_ECU (420) and receives IG on/off signals separately. Based on the operation of the passenger of a hybrid vehicle, the HV_ECU (320) controls open/close operation of an SMR (500) which electrically connects and interrupts a battery (220) for driving and a load. When abnormality of a communication line is detected, the HV_ECU (320) does not turn off the SMR (500) until a set delay time elapses even if an IG off signal is inputted. After the IG off signal is inputted, the EPS_ECU (420) performs evacuation operation during delay time.
