PROBLEM TO BE SOLVED: To provide a switch control device that controls a switch of a power source system which supplies power from a first power source and a second power source to a first electric load and a second electric load via the switch, which can suppress inconvenience that can be caused by the state change of the switch.SOLUTION: A control portion 30, when a first state in which switches 21 and 24 are brought into an ON-state and switches 22 and 23 are brought into an OFF state is switched into a second state in which the switches 22 and 23 are brought into the ON-state and the switches 21 and 24 are brought into the OFF state, executes control so that the first state is switched to a third state in which all switches 21-24 are brought into the ON-state and then switched into the second state. Current consumptions of a rotary electric machine 17 are larger than current consumptions of an electric load 15, and allowable currents of the switch 22 are larger than allowable currents of the switch 23 and the switch 24. Therefore, the control portion, when the first state is switched into the third state, brings the switches 22 and 23 into the ON-state simultaneously, or brings the switch 22 into the On-state before the switch 23.SELECTED DRAWING: Figure 1
【課題】第1電源及び第2電源から第1電気負荷及び第2電気負荷へスイッチを介して電力を供給する電源システムのスイッチを制御するスイッチ制御装置において、スイッチの状態変更に伴って生じうる不都合を抑制する。【解決手段】制御部30は、スイッチ21,24をオン状態、スイッチ22,23をオフ状態とする第1状態から、スイッチ22,23をオン状態、スイッチ21,24をオフ状態とする第2状態へ切り替える際、第1状態から、スイッチ21〜24を全てオン状態とする第3状態へ切り替えた後、第2状態へと切り替える制御を実施し、回転電機17の消費電流量は、電気負荷15の消費電流量より大きく、スイッチ22は、スイッチ23及びスイッチ24に比べて、許容電流量が大きいものであり、第1状態から第3状態へ切り替える際、スイッチ22,23を同時にオン状態とするか、又は、スイッチ23より先にスイッチ22をオン状態にする。【選択図】 図1
