Embodiment Construction

[0014] The following description pertains to adjusting a vehicle grille shutter to adjust an engine system such as figure 1 A system and method for cooling the engine system shown). Vehicle grille shutters may be positioned at the grille of the vehicle's front end, such as figure 2 shown. A grille shutter opening percentage may be adjusted based on engine operating conditions to increase or decrease cooling air flow to the engine. Specifically, the engine controller may send the commanded grille shutter position to a motor coupled to the grille shutter, such as image 3 motor shown. The motor may then adjust the grille shutters to the commanded position. Figure 4 Different grille shutter positions are shown relative to the opening angle of the grille shutters. In some cases, after adjusting the grille shutters, the actual resulting grille shutter position may differ from the commanded grille shutter position (resulting in a position error). This position error may be c...

Abstract

Methods and systems are provided for adjusting vehicle grille shutters based on a direction of motion of the grille shutters. In one example, a method includes adjusting a motor coupled to the grille shutters based on the direction of motion of the grille shutters, a desired opening of the grille shutters, and vehicle speed. Further, the method may include determining the direction of motion of the grille shutters based on a desired motor position relative to an actual motor position.

Description

technical field [0001] The present application relates to a method for adjusting grill shutters of a vehicle based on vehicle speed and direction of grill shutter adjustment. Background technique [0002] A vehicle grille is typically located at the front end of the vehicle and may be configured to provide openings, such as grille openings or bumper openings, through which intake air is received from the outside of the vehicle. This intake air may then be directed to the engine compartment of the vehicle to assist the vehicle cooling system in cooling the engine, transmission, and other such components of the engine compartment. This flow of air through the grille can add aerodynamic drag when the vehicle is in motion. Accordingly, the grille may include grille shutters / louvers that impede this air flow, thus reducing aerodynamic drag and improving fuel economy. A closed grille shutter also provides faster drivetrain warm-up, which improves fuel economy because there is le...
