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 for diagnosing demagnetization of a motor of a vehicle can accurately diagnose an irreversible demagnetization state of a permanent magnet of a traction motor or a hybrid starter-generator (HSG) without additional hardware, while minimizing influence of irreversible demagnetization of the permanent magnet of the traction motor or the HSG on vehicle performance. The method includes acquiring operating state information of the motor, determining whether a diagnosis entrance condition including a state in which the motor performs an electricity generating operation is satisfied based on the acquired operating state information of the motor, acquiring a direct current (DC) value in diagnosis, and determining whether irreversible demagnetization occurs by comparing the acquired DC value in diagnosis with a pre-stored DC current value in a normal state of the permanent magnet.
