A vehicle has an engine (26), a power storage device (10), two motor/generators (M/G1, M/G2), a front grille with a shutter, an engine room, a first temperature sensor, a second temperature sensor, and a controller. The shutter changes the amount of air introduced from the front grille into the engine room. The first temperature sensor detects a temperature (Tw) of a coolant of the engine, and outputs the detected coolant temperature to the controller. The second temperature sensor detects an outside air temperature (Te), and outpots the detected outside air temperature to the controller. The controller starts the engine (26) when the coolant temperature is equal to or lower than a threshold value. When the coolant temperature is higher than the threshold value, and the vehicle starts traveling in a first mode with power from the power storage device (10), the controller drives the shutter such that the amount of the air is reduced when the coolant temperature (Tw) is higher than the outside air temperature (Te).

Disclosed is a wheeled vehicle. The wheeled vehicle includes various features for operation by a rider, such as a throttle actuation assembly and various components for operation and manipulation of the vehicle.

An active air flap system mounted in a predetermined portion of a vehicle, includes: a housing, a flap mounted on the housing to be relatively movable, an actuator coupled to the at least one flap and configured to drive the at least one flap, and a power transfer mechanism engaging the actuator and the flip and configured to transfer power from the actuator to the at least one flap so that the at least one flap performs a dual operation of a sliding movement operation and a rotation operation of rotating around a predetermined rotation axis, preventing the occurrence of design heterogeneity and the air resistance caused by forming the space between the at least one flap and the radiator grill, and improving shielding properties.

A vehicle structure includes a cooling device, an air guide member, and a horn. The cooling device is cooled with a flow of moving air which a vehicle receives while traveling. The air guide member guides the moving air into the cooling device. The air guide member has a single opening in a front of the vehicle. The horn is disposed at a side of the air guide member. The cooling device and the horn are arranged in a vehicle-width direction. The cooling device and the horn face the single opening viewed form the front of the vehicle.

A radiator unit includes a cooling air duct, a first heat exchanger that is arranged in the cooling air duct and incompletely fills out the cross section of the cooling air duct and a second heat exchanger that fills out at least the part of the cross section not filled out by the first heat exchanger. An air flap arrangement meters a cooling air flow through the heat exchangers. A first part of the air flap arrangement predominantly fluidically overlaps the first heat exchanger. A second part of the air flap arrangement predominantly fluidically overlaps the part of the cross section not filled out by the first heat exchanger. The air flaps of the first and second part are coupled for swiveling in opposite directions around axes that are parallel to a boundary between the two parts.

A flap system for supplying cooling air of a motor vehicle, and which includes a drive component which receives and supports at least one flap element to be pivoted about a longitudinal axis. The flap element is to be supported at ends thereof by a shaft which is received in a cylindrical bearing receiving member of a rail.

A grille shutter is a device configured to adjust a temperature of coolant water of an engine by adjusting an amount of outside air introduced into a radiator of the engine. An ECU performs a failure diagnosis for the engine based on a temperature of coolant water of the engine. When the grille shutter is immovable in an opened state of the grille shutter regardless of an operating command to the grille shutter, the ECU renders the failure diagnosis process for the thermostat valve not to be executed. As a result, an incorrect operation of various controls executed based on a temperature of coolant water of the engine can be suppressed.

A mid-mounted radiator in a motor vehicle has at least one outgoing air guide attached laterally on the left and right of the radiator. In vehicles with a relatively low cooling requirement, the lateral outgoing air guides are removed and the openings are closed by a cover.
