Vehicle, control apparatus for vehicle, and control method for vehicle

A control apparatus for a vehicle that is mounted with a first electric storage device, a second electric storage device, and a converter, comprising:

• a control unit that sets a target voltage to a first voltage if a system stop period from a last stop time point when a system of the vehicle is stopped to an activation time point when the system of the vehicle is activated is longer than a first period,
• sets the target voltage to a second voltage, which is lower than the first voltage, if the system stop period is equal to or shorter than the first period, and
• controls the converter such that a voltage of an electric power supplied from the first electric storage device to the second electric storage device becomes equal to the target voltage, wherein
• the first electric storage device supplies an electric power to an electric rotating machine as a drive source,
• the second electric storage device supplies an electric power to an electric component different from the electric rotating machine, and has a lower voltage than the first electric storage device, and
• the converter adjusts the voltage of the electric power supplied from the first electric storage device, and supplies the voltage-adjusted electric power at least to the second electric storage device.
