摘要： A method and a system for diagnosing insufficiency of vehicle coolant includes a preparing step of checking whether the vehicle is in a stop state and is on flat ground. An operating step applies a predefined output to a coolant water pump when the vehicle is in the stop state and is on flat ground. A measuring step measures a rotation speed of an impeller of the coolant water pump for a period in which the predefined output is applied to the coolant water pump. A M determining step compares the measured rotation speed of the impeller of the coolant water pump with a reference speed to determine whether or not the coolant is insufficient.

摘要： A method of estimating a temperature of a permanent magnet in a motor that is capable of precisely estimating the temperature of a permanent magnet included in a motor and of preventing demagnetization of the magnet is provided. Specifically, the method of estimating a temperature of a permanent magnet in a motor is capable of deriving heat transfer coefficients through an analysis of an interrelation between a variation of permanent magnet temperature and a rotor loss per motor operating condition based on an actually measured value and constructing a heat model of the permanent magnet using the same to estimate the temperature of the permanent magnet, and accordingly, it is possible to precisely estimate real-time temperature of the permanent magnet based on the operational condition of the motor.
