Abstract
A controller disclosed in the specification is implemented in an electrified vehicle in which a motor generator used to drive a wheel is connected to a battery via a DC-DC converter. The controller is configured to be able to execute a process of acquiring a target value of output voltage of the DC-DC converter, a process of acquiring a measured value of the output voltage of the DC-DC converter, a process of acquiring a direction of reactor current flowing through a reactor of the DC-DC converter, and a process of executing feedback control over an operation of the DC-DC converter in accordance with a deviation of the measured value from the target value of the output voltage. The process of executing feedback control may include a process of determining a feedback gain that varies with the direction of the reactor current.
