Problems solved by technology

However, during such conditions, engine temperature control may require effective cooling
While other vehicle cooling components such as cooling fans and coolant circulation systems can be used for vehicle cooling during these conditions, continued use of such cooling components increases engine parasitic losses
Specifically, increased engine power or battery power consumption adversely affects engine fuel efficiency and performance

Abstract

Methods and systems are provided for estimating a cooling demand of a vehicle powertrain component and selecting a mode of operation of a vehicle cooling system based on the estimated cooling demands of the vehicle powertrain component and the energy usage of the cooling system components. Based on the selected operating mode, each of a radiator fan speed, a coolant system pump output, a vehicle grille shutter opening, and an opening of vents coupled to a powertrain component insulating enclosure may be concurrently adjusted to minimize the cooling parasitic losses while satisfying the cooling requirements of the vehicle.

Description

technical field [0001] The present description generally relates to methods and systems for tuning various components of a vehicle cooling system. technical background [0002] A vehicle cooling system may include multiple cooling components such as radiators, cooling fans, coolant circulation systems, and the like. The different cooling components operate using power from the engine and / or from the battery. Additionally, the cooling system may receive cooling air from the front end of the vehicle, such as through active grille shutter (AGS) openings, to help cool the engine, transmission, and other components in the underhood area. This type of frontal airflow can cause a parasitic loss of engine power by increasing aerodynamic drag when the vehicle is in motion. [0003] Different approaches may be used to reduce vehicle aerodynamic drag due to AGS opening when providing cooling to vehicle components. One exemplary method for AGS adjustment is shown by Klop et al. in US...
