Abstract
A backup power supply system for a shift-by-wire system includes a power storage unit and a control unit. Power storage unit supplies power to a shift-by-wire system. When at least one of a first condition or a second condition is satisfied, control unit outputs an instruction signal, instructing that a shift range of an automatic transmission should be changed into a parking range, to shift-by-wire system. First condition requires that the duration for which output voltage of the mains power supply remains equal to or less than a first voltage threshold value should be longer than a first duration. Second condition requires that the duration for which the output voltage of the mains power supply remains equal to or less than a second voltage threshold value, smaller than the first voltage threshold value, should be longer than a second duration which is shorter than the first duration.
