Problems solved by technology

[0009] When the oil injection speed is increased in response to an increase in the temperature of the driving motor, if the oil injection speed is increased beyond a certain speed, there is a problem that the injected oil does not flow into the driving motor after the oil contacts the coil of the driving motor. into the coils of the motor, but instead flow down the shape of the coils or bounce off the coils and fly out to the outside of the drive motor
[0010] In this way, when the oil injection speed is increased in response to an increase in the temperature of the drive motor, even if a large amount of oil is injected, most of the injected oil is not used to cool the drive motor, thereby reducing the cooling performance of the drive motor

Abstract

An oil pump, a vehicle having the same and a method of controlling the vehicle are provided. The 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.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims the benefit of priority from Korean Patent Application No. 10-2020-0039724 filed with the Korean Intellectual Property Office on April 1, 2020, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to an oil pump for effectively cooling a driving motor, a vehicle having the oil pump, and a method of controlling the vehicle, and more particularly, relates to a method for controlling the temperature of the motor according to the temperature gradient of the motor when the target speed of the oil pump is greater than or equal to the limit speed. An oil pump to adjust the speed of the oil pump. Background technique [0004] Vehicles running on roads are equipped with various devices for protecting occupants, assisting driving, and improving ride comfort. [0005] Examples of vehicles include motor vehicles ...
