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.

A method for controlling a vehicle in the event of an oil-pump failure may include: a first comparison step of comparing, by a controller, an actual RPM of an EOP with a first set value set in advance based on a target RPM of the EOP; a maximum EOP driving step of driving the EOP to a maximum output by the controller when a result of the comparison in the first comparison step shows that the actual RPM is smaller than or equal to the first set value; a second comparison step of comparing the actual RPM of the EOP with a second set value by the controller after the maximum EOP driving step; and a creep driving step of making the vehicle perform creep driving using a motor by the controller when a result of the comparison in the second comparison step shows that the actual RPM is larger than the second set value.
