VEHICLE AND METHOD FOR CONTROLLING THE SAME
First Claim
1. A vehicle comprising:
- a driving motor connected to a vehicle wheel and configured to supply driving force to the vehicle wheel;
a power converter connected to an external power source and the driving motor and configured to use a coil provided in the driving motor to transform power input from the external power source;
a battery connected to the power converter and configured to be charged according to counter electromotive force of the driving motor in a regenerative braking mode, charged according to the power transformed by the power converter in a charging mode, and supply driving power to the driving motor in a driving mode;
an oil pump configured to supply oil to the driving motor;
a detector configured to detect oil temperature of the oil; and
a controller connected to the oil pump and configured to control the oil pump to be operated in a warm-up mode when the oil temperature detected by the detector is less than a first threshold temperature and the battery is in the charging mode, and apply reference power to the oil pump to move the oil to the driving motor in the warm-up mode.

12. A method for controlling a vehicle having a driving motor configured to apply driving force to a vehicle wheel and a battery configured to supply power to the driving motor, the method comprising:
-
detecting oil temperature of oil stored in an oil reservoir; determining, by a controller, when the vehicle is operated in a charging mode when the detected oil temperature is lower than a first threshold temperature; operating, by the controller, an oil pump in a warm-up mode when the vehicle is operated in the charging mode; checking, by the controller, temperature of the oil during the warm-up mode of the oil pump; and operating, by the controller, the oil pump in a normal mode when the checked oil temperature is higher than a second threshold temperature, wherein the operating of the oil pump in the warm-up mode includes applying reference power to the oil pump such that the oil is moved to the driving motor, and wherein the first threshold temperature is lower than the second threshold temperature. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
