PROBLEM TO BE SOLVED: To prevent excessive prolongation of time required for a bypass switch element to be turned on, when an output current of a voltage converter is in a state of exceeding a current threshold.SOLUTION: A vehicular power supply controller comprises: a first power storage part in which an upper limit voltage is set to a prescribed voltage value; a second power storage part in which an upper limit voltage is set to a voltage higher than the prescribed voltage value, and which can be charged/discharged faster than the first power storage part; and a control part which, when an output current of a voltage converter exceeds a predetermined current threshold in an OFF state of a bypass switch element, executes operation of a bypass transition mode for a predetermined transition time, and when the transition time has passed, terminates the bypass transition mode operation and executes a bypass mode operation. In the bypass transition mode, the control part stops power generation of a power generator and determines whether a predetermined operation condition is fulfilled or not, and when the operation condition is determined to be fulfilled, a high voltage electric load is forcedly actuated.SELECTED DRAWING: Figure 1
【課題】電圧変換器の出力電流が電流閾値を超えた状態になったときに、バイパススイッチ素子がオンにされるまでに要する時間が過度に長くなるのを防止する。【解決手段】車両用電源制御装置は、上限電圧が所定電圧値に設定された第1蓄電部と、上限電圧が所定電圧値より高い電圧に設定され、第1蓄電部より急速な充放電が可能な第2蓄電部と、バイパススイッチ素子がオフの状態で、電圧変換器の出力電流が予め定められた電流閾値を超えると、バイパス移行モードの動作を予め定められた移行時間の間実行し、移行時間が経過すると、バイパス移行モードの動作を終了してバイパスモードの動作を実行する制御部と、を備える。制御部は、バイパス移行モードでは、発電機の発電を停止させ、予め定められた作動条件が満たされるか否かを判定し、作動条件が満たされると判定すると高電圧電気負荷を強制的に作動させる。【選択図】図1
