Abstract

A method of controlling a vehicle includes steps of: detecting a temperature of oil; detecting a temperature of a drive motor; identifying a target rotational speed of an oil pump corresponding to the detected temperature of the oil and the temperature of the drive motor; when the identified target rotational speed is less than a limit rotational speed, controlling an operation of the oil pump based on the identified target rotational speed; and when the identified target rotational speed is greater than or equal to a limit rotational speed, adjusting the identified target rotational speed based on a temperature gradient of the drive motor in a current period and a temperature gradient of the drive motor in a previous period and controlling the operation of the oil pump based on the adjusted target rotational speed.
