COOLING PUMP DRIVING SYSTEM |
| 摘要 |
A cooling pump driving system includes an electric water pump in a coolant passage line for circulating a coolant and having a variable rotation speed. A sensor disposed at an outlet side of the electric water pump checks a coolant pressure passing through the electric water pump. A controller including a reference value for the pressure change is configured to decrease a rotation speed of the electric water pump when the pressure change detected by the sensor is the reference value or higher. |
