Abstract
A vehicle comprises a grille opening, a grille shutter, an Fr spoiler, and a controller, wherein the controller is configured to open the grille shutter when the vehicle speed is less than a first threshold value or when the evaluation indices and of the temperature of the cooling target are equal to or greater than the reference values; and the controller is configured to bring the Fr spoiler into the deployed posture when the vehicle speed is equal to or greater than a second threshold value higher than the first threshold value, and to bring the Fr spoiler into the deployed posture in synchronization with the opening of the grille shutter when the vehicle speed is equal to or greater than the first threshold value and less than the second threshold value.
Claims3
A vehicle comprising:
- a grille opening formed at a front end of the vehicle and configured to allow air to flow toward a cooling target;
- a grille shutter configured to enable the grille opening to open and close;
- a front spoiler disposed at a lower front portion of the vehicle and configured to be capable of changing between a storage posture and a deployed posture protruding downward of the vehicle relative to the storage posture;
- and
- a controller, wherein the controller is configured to:
- open the grille shutter when the vehicle speed is less than a first threshold value or when an evaluation index of a temperature of the cooling target is equal to or greater than a reference value,
- change the front spoiler to the deployed posture when the vehicle speed is equal to or greater than a second threshold value higher than the first threshold value;
- and
- change the front spoiler to the deployed posture in synchronization with the opening of the grille shutter when the vehicle speed is equal to or greater than the first threshold value and less than the second threshold value,
- the cooling target is a heat exchanger that causes an air conditioning refrigerant to exchange heat with outside air, and
- the evaluation index is a pressure of the air conditioning refrigerant.
A vehicle comprising:
- a grille opening formed at a front end of the vehicle and configured to allow air to flow toward a cooling target;
- a grille shutter configured to enable the grille opening to open and close;
- a front spoiler disposed at a lower front portion of the vehicle and configured to be capable of changing between a storage posture and a deployed posture protruding downward of the vehicle relative to the storage posture;
- and
- a controller, wherein
- the controller is configured to open the grille shutter when the vehicle speed is less than a first threshold value or when an evaluation index of a temperature of the cooling target is equal to or greater than a reference value,
- change the front spoiler to the deployed posture when the vehicle speed is equal to or greater than a second threshold value higher than the first threshold value;
- and
- change the front spoiler to the deployed posture in synchronization with the opening of the grille shutter when the vehicle speed is equal to or greater than the first threshold value and less than the second threshold value;
- another aerodynamic device which can be changed to a first posture and a second posture in which an aerodynamic resistance of the vehicle is reduced as compared to the first posture, wherein
- the other aerodynamic device includes at least one of a rear spoiler, a spat, or a side step, and
- the controller is configured to change the other aerodynamic device to the second posture in synchronization with a change of the front spoiler to the deployed posture.
