Grille shutter control device for vehicle cooling performance optimization
A recently granted patent (Publication Number: US12000327B2) discloses a grille-shutter control apparatus designed to manage the opening and closing of a vehicle's grille shutter. This innovative system includes a processor that can select from a variety of opening-degree determination logics stored in memory based on the temperature of the atmosphere inside the exhaust pipe or catalyst of the internal combustion engine. The selected logic is then executed to control the grille shutter accordingly, ensuring optimal performance.
The apparatus features multiple opening-degree determination logics, including prioritizing raising the atmosphere's temperature or maximizing the vehicle's fuel economy performance. The processor intelligently selects the appropriate logic based on the atmosphere's temperature, either below or above a specified threshold. Additionally, when the selected logic is executed with the grille shutter open, the processor adjusts the opening and closing based on conditions that minimize the likelihood of changes to the shutter's state compared to when the logic is executed with the shutter closed. This advanced control system aims to enhance the vehicle's efficiency and performance by dynamically managing the grille shutter based on real-time conditions.
