Disclosed is a cooling system of a vehicle. The cooling system includes an integrated controller for controlling a cooling fan and an active air flap, wherein the cooling fan is connected to the integrated controller through a single data line, and the active air flap is connected to the integrated controller through a single data line. The integrated controller is configured to receive signals of temperatures of cooling water and ambient air via controller area network (CAN) communication using two data lines.

Methods and systems are provided for adjusting grille shutters based on engine coolant temperature and a difference in aerodynamic drag between the grille shutter positions. In one example, the grille shutters may be adjusted into a position closer to a first smaller opening when a difference in aerodynamic drag between the first and second positions is large. In other examples, the grille shutters may be adjusted into a position closer to the second larger opening when a difference in aerodynamic drag between the first and second positions is small thus maintaining the engine at lower temperatures.

The invention relates to a thermostat valve for an internal combustion engine, comprising a housing having a plurality of cooling fluid connections and comprising at least two hollow valve elements, which are arranged adjacent to one another and are mounted in the housing so as to be rotatable about a common rotational axis, wherein the valve elements each have at least one opening which is formed in the region of their shell surface, wherein the openings can be connected selectively to one or more, of the cooling fluid connections of the housing by rotating the valve elements, wherein drive means are provided with which a first of the at least two valve elements can be rotated between two end positions, wherein a second of the at least two valve elements can be coupled selectively to the first valve element and decoupled from the first valve element, wherein in the state in which it is coupled to the first valve element the second valve element is also driven in rotation by a rotation of the first valve element, and wherein coupling means are provided which are actuated by rotating the first valve element into the first end position, in such a way that the second valve element is coupled to the first valve element, and which are actuated by rotating the first valve element into the second end position in such a way that the second valve element is decoupled from the first valve element.

Provided is a system for controlling opening/closing of a shutter for a vehicle, which allows the shutter to be appropriately opened and closed on the whole travel path of the vehicle. A control device for the shutter includes: an opening/closing control unit that brings the shutter into an open state when a temperature in an engine room exceeds a predetermined threshold, and brings the shutter into a closed state when the temperature is the threshold or less; and a traveling state predicting unit that predicts a traveling state of the vehicle after a lapse of a predetermined time based on map information and path information. The opening/closing control unit has a threshold changing section that changes the threshold based on the traveling state of the vehicle after the lapse of the predetermined time predicted by the traveling state predicting unit.
