| 发明名称 | Shutter control during ambient temperature warm-up across a freezing point | ||
| 摘要 | A method of controlling operation of an adjustable shutter adapted for varying an amount of airflow to cool a powertrain in a vehicle includes monitoring the ambient temperature. The method also includes sensing an increase in the ambient temperature up to a threshold temperature value. The method additionally includes changing a position of the shutter after a predetermined amount of time has elapsed following the increase in the ambient temperature up to the threshold temperature value. A vehicle using a controller to perform such a method is also provided. | ||

| 主权项 | 1. A method of controlling operation of an adjustable shutter adapted for varying an amount of airflow to cool a powertrain in a vehicle, the method comprising: monitoring the ambient temperature; sensing an increase in the ambient temperature from below the freezing point of water up to a threshold temperature value that is above the freezing point; and changing a position of the shutter after a predetermined amount of time has elapsed following the increase in the ambient temperature up to the threshold temperature value, wherein the predetermined amount of time is indicative of an amount of time needed to thaw ice on the shutter. | ||
