Provided is a passenger protection system including a passenger protection device (11), an acceleration sensor (16), a control unit (13), a switch unit (Q), and a power source unit. The passenger protection system has the following: a startup unit (12) that switches the switch unit to be in a conductive state or a non-conductive state depending on whether or not a supply voltage (E1) supplied from a battery to a first power source line (L1) through an ignition switch (IGSW) is greater than or equal to a voltage threshold; a second power source line (L2) that electrically connects the battery to the power source unit through the switch unit but not through the ignition switch; and a vehicular speed reflection unit (15) that switches the switch unit to be in the conductive state or the non-conductive state according to a calculated value calculated using an acceleration detected by the acceleration sensor. |
