<p><P>PROBLEM TO BE SOLVED: To provide a backup power source system which can restrain an increase in cost, the volume and weight, while restraining electric power consumption in the whole vehicle, while supplying required electric power to a control apparatus when a power source is abnormal. <P>SOLUTION: The backup power source system 1 includes an electronic control brake 50 for operating a brake of a vehicle by receiving electric power supply from a DC/DC converter 20 mounted on the vehicle, and a backup power source 60 for supplying electric power to the electronic control brake 50 when the power source is abnormal when a value of voltage supplied to the electronic control brake 50 is less than a predetermined value. The backup power source 60 has a capacitor 61. Charging voltage of the capacitor 61 is particularly set to high voltage as the temperature of the backup power source 60 becomes low, and is set to high voltage as a speed of the vehicle becomes high. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
