METHOD OF DIAGNOSING ELECTRONIC WATER PUMP OF ENGINE |
| 摘要 |
A method for diagnosing an electronic water pump of an engine in a vehicle includes determining whether a stall occurs while a sensorless 3-phase motor used for the electronic water pump of the engine is driven, based on a peak value of a torque of the motor. The method further includes determining whether the stall occurs while the motor is stopped, based on the torque of the motor. |
