|Title:||IN-VEHICLE POWER SUPPLY UNIT CONTROL DEVICE AND IN-VEHICLE POWER SUPPLY DEVICE|
Even when abnormality occurs on the high-voltage side than a predetermined position within an in-vehicle power supply unit, the present invention can supply power to a path on the low-voltage side, said power being based on an electricity storage unit on the low-voltage side than the predetermined position. An in-vehicle power supply unit control device (2) is provided with: a bypass conductive path (72) forming a path for supplying power from a first position (P1) between electricity storage units in an in-vehicle power supply unit (91) to a second conductive path (82); a bypass relay (74) interposed in the bypass conductive path (72); and a protection relay (54) disposed between the electricity storage units on the high-potential side than the first position (P1). A control unit (20) switches between a first switching control and a second switching control, said first switching control bringing the protection relay (54) into an on-state and the bypass relay (74) into an off-state, said second switching control bringing the protection relay (54) into an off-state and the bypass relay (74) into an on-state.
