1. A vehicle control device for controlling a vehicle including a transmission, the transmission including a first oil pump driven by rotation of a drive source that drives a drive wheel, and a second oil pump provided with a check valve on a suction side and driven by a motor, wherein
a minimum value of a drive current value of the motor is defined as a first current value, when the second oil pump is driven in a normal drive state, and
a minimum rotation speed of the drive source is increased compared to a case in which the drive current value of the motor is equal to or larger than the first current value, when an automatic downshift control for automatically downshifting a speed ratio of the transmission is executed in a case in which the drive current value of the motor is smaller than the first current value when the second oil pump is driven.
