METHOD AND SYSTEM FOR ADJUSTING GRILLE SHUTTERS BASED ON TEMPERATURE AND POSITION FEEDBACK |
| 摘要 |
Methods and systems are provided for adjusting vehicle grille shutters based on engine coolant temperature. In one example, a method includes adjusting grille shutters based on engine coolant temperature and additional engine operating conditions when engine coolant temperature is below a threshold and adjusting the grille shutters base on the engine coolant temperature only when the engine coolant temperature is above the threshold. Further, the method may include recalibrating a position of the grille shutters based on a grille shutter position error. |

1. An engine method, comprising:
during a first condition, adjusting grille shutters based on engine coolant temperature (ECT) and additional engine operating conditions; and during a second condition when ECT is greater than a threshold temperature, adjusting the grille shutters from a partially open position based on ECT independent of the additional engine operating conditions. |
