A drive device (40) is fastened to the main body (20) and generates a moving force for the slat (30). A lever mechanism (50) forms an operative connection between the drive device (40) and the at least one slat (30). The lever mechanism (50) has at least one drive lever (52) operatively connected to the drive device (40) in a torque-transmitting manner and fastened in an end position (EP) of a keyhole opening (26) in the main body (20).

A heat exchanger system for an agricultural vehicle. The heat exchanger system has at least two separate heat exchanger assemblies, where an adjustable baffle is used to vary the airflow between the heat exchanger assemblies, accordingly varying the cooling effect of the assemblies, based on system requirements. The adjustable baffle may be arranged to restrict or block at least a portion of a heat exchanger to reduce airflow through the exchanger, to provide a flow bypass of an exchanger, and/or to proportionally adjust the airflow through a pair of heat exchangers provided as part of a single heat exchanger assembly.

An actuation mechanism for at least partially asynchronously actuating two closure devices of an air flow control assembly for a vehicle, comprising a control element that is/can be connected to an actuator. This is operatively connected via a first coupling part provided for actuating the first closure device and via a second coupling part provided for actuating the second closure device in such a way that a movement of the control element occurring about an axis of rotation can be converted into a shifting of the two coupling parts via a slide controller having corresponding control pins and bearing grooves. The control element having the control pins is integrated at least partially between the two coupling parts which are at least partially overlapping and can be shifted relative to the control element. The control pins engage at least partially into the bearing grooves positioned on the coupling parts.

A method is provided for diagnosing an AGS system fault in a hybrid electric vehicle. That method includes validating shutter movement and inferring shutter position based upon stall current of a shutter drive motor and current drawn by an HEV traction motor. A new and improved active grill shutter system for a hybrid electric vehicle is also disclosed.

The present disclosure relates to a system for controlling an air flow rate into a vehicle engine room. The system includes: an air intake port receiving an exterior air at a front portion of the vehicle and supplying the air into the engine room; air ducts formed at both sides of the air intake port and introduce the exterior air into a wheel side in order to improve aerodynamic characteristic; a control valve configured to selectively convey the air flowed in the air intake port into the air ducts; a radiator disposed between the air intake port and the engine room; and a control portion configured to control the control valve based on an operating state of vehicle. The air ducts are selectively communicated with the air intake port and disposed at upstream of the radiator.

Provided are a vehicle and a control method for the vehicle. The vehicle includes an engine, a fuel tank configured to store a fuel for the engine, a grille shutter, and an ECU. The grille shutter is configured to regulate an introduction air from an outside of the vehicle to an inside of the vehicle. The ECU is configured to determine whether or not the fuel is deteriorating. The ECU is configured to control the grille shutter such that an amount of the introduction air in a case where the fuel is deteriorating is larger than an amount of the introduction air in a case where the fuel is not deteriorating.
