An auxiliary power supply apparatus is disposed on a power supply path from a main power supply apparatus to an electric power steering apparatus. The auxiliary power supply apparatus includes an auxiliary power supply that is a rechargeable power storage device, an on-off switch that is configured to selectively disconnect or connect the electric power steering apparatus and the auxiliary power supply from or to the main power supply apparatus, and an operation unit that is configured to operate the on-off switch. The operation unit is configured to switch the on-off switch from an ON state to an OFF state on a condition that a voltage supplied to the auxiliary power supply apparatus from the main power supply apparatus is less than or equal to a specified voltage reduction determination value and a vehicle speed is greater than a specified low vehicle speed determination value.
