    • An electric power is surely supplied to a load even if an abnormality is generated in a switching control circuit, which controls a switching part that switches electric connection between a power supply and the load of a vehicle. The switching control circuit controls a state of a contact of a keep relay that switches the electric connection between the power supply and the load. A monitor circuit monitors existence or non-existence of the abnormality of the switching control circuit. When detecting the abnormality of the switching control circuit, the monitor circuit transmits a reset signal in order to reset a state of the switching control circuit. When receiving the reset signal from the monitor circuit, an abnormal-time connection circuit transmits a connection signal to a coil of the keep relay to bring a movable contact into contact with a contact. For example, the present invention can be applied to a power-supply control device for the vehicle.
    • 即使在切换控制电路中产生异常的电力被确实地供给负载,开关控制电路控制切换部件,其切换电源与车辆的负载之间的电连接。 切换控制电路控制切换电源和负载之间的电连接的保持继电器的接触状态。 监视器电路监视开关控制电路的异常的存在或不存在。 当检测到开关控制电路的异常时,监视电路发送复位信号以复位开关控制电路的状态。 当从监视电路接收到复位信号时,异常时间连接电路将连接信号发送到保持继电器的线圈,使可动触头与触点接触。 例如,本发明可以应用于车辆的电源控制装置。
