PROBLEM TO BE SOLVED: To enhance the fuel consumption of a vehicle by lightening a backup power supply to reduce the weight of the vehicle.SOLUTION: A backup power supply device 8 includes a power supply input unit 9, an output unit 10, a capacitor unit 11, a charging circuit unit 12 provided in a charging path from the power supply input unit 9 to the capacitor unit 11, a boosting circuit unit 13 provided in an output path to the capacitor unit 11 and the output unit 10, and a collision prediction signal input unit 14. When the capacitor unit 11 is charged to a charging voltage in advance by the charging unit 12 and the voltage of the power supply input unit 9 is lower than a threshold value, a boosted voltage boosted from the charging voltage in the boosting circuit unit 13 is output from the output unit 10 in response to reception of a signal by the collision prediction signal input unit 14.SELECTED DRAWING: Figure 1
【課題】バックアップ電源を軽量化して車両を軽量化することにより、車両の燃費を向上させる。【解決手段】バックアップ電源装置8は、電源入力部9と、出力部10と、キャパシタ部11と、電源入力部9からキャパシタ部11への充電経路に設けられた充電回路部12と、キャパシタ部11と出力部10への出力経路に設けられた昇圧回路部13と、衝突予測信号入力部14と、を含む。キャパシタ部11は予め充電回路部12により充電電圧に充電され、電源入力部9の電圧が閾値よりも低い場合に、昇圧回路部13で充電電圧から昇圧された昇圧電圧が、衝突予測信号入力部14が信号を受信したことに応じて、出力部10から出力される。【選択図】図1
