车辆及车辆的控制方法
摘要：
本发明提供一种车辆及车辆的控制方法，在车辆及车辆的控制方法中，通过有效且更准确地计算电动马达内的永磁体的温度以调节供应给电动马达的电力量来防止电动马达的性能劣化。该车辆包括：电动马达，包括定子、转子和永磁体；传感器，测量电动马达的温度；逆变器，驱动电动马达；以及控制器，通过使用逆变器向电动马达供应电力来产生预定的热量，基于使用传感器测量的预定点的电动马达的温度来计算永磁体的温度，并且当永磁体的温度超过预定温度时，控制器减少电力的供应。
摘要（英）：

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.
