    Abstract: A vehicle and method of controlling the same are provided in which the performance of an electric motor is prevented from being degraded by efficiently and more accurately calculating the temperature of a permanent magnet within the electric motor to adjust the amount of power supplied to the electric motor. The vehicle includes an electric motor having a stator, a rotor, and a permanent magnet and a sensor that measures the temperature of the electric motor. An inverter drives the electric motor and a controller generates a predetermined heat quantity by supplying power to the electric motor to calculate the temperature of the permanent magnet based on the temperature of the electric motor at a predetermined point measured using the sensor. When the temperature of the permanent magnet exceeds a predetermined temperature, the controller reduces the supply of the power.
