A method, system, and apparatus are provided for optimizing control of the rotational speed of a fan in a vehicle so as to reduce the aerodynamic drag of a vehicle in a given operating parameter, and accordingly, to improve fuel efficiency of operation of the vehicle. Certain exemplary embodiments include determining an optimized speed of rotation of a cooling fan of the vehicle for reducing overall fuel demand in given operating conditions, and controlling rotation speed of the fan at the optimized speed in order to minimize fueling demand of a prime mover of the vehicle.

A tire smoke induction prevention system for a motor vehicle includes a tire smoke condition feature and a controller. The tire smoke condition feature may be adapted to produce a warning signal when potential for tire smoke generation exceeds a predetermined level or likelihood. The controller is adapted to respond to such a warning signal and engage a climate control system of the motor vehicle in recirculation mode. A related method for preventing the induction of tire smoke into a passenger cabin of a motor vehicle is also provided.

An air outlet apparatus for an interior of a motor vehicle includes a first ventilation gap and a second ventilation gap, which are spaced apart from each other, a decorative element, which is coupled to a fitting covering for the motor vehicle and arranged between the first and the second ventilation gap, and a control unit, which is coupled to the decorative element and has a first regulating element and a second regulating element. An intensity of an air flow through at least one of the ventilation gaps and, by way of the second regulating element, an alignment of the air flow through at least one of the ventilation gaps can be adjusted independently of each other.

Provided is a high-voltage equipment cooling system for electric-powered vehicles, which is capable of cooling high-voltage equipment (an IPU herein) at an optimum air flow rate without impairing the air-conditioning state of a vehicle interior. This high-voltage equipment cooling system is equipped with an IPU cooling ECU with a control unit, which controls the air flow rate of an IPU fan on the basis of information related to the air blowing method for the IPU, information related to the air flow rate of a blower fan, information related to the selection of inside air circulation mode or outside air introduction mode by an HVAC, information related to the selection of one of air blowing modes by the HVAC, and information related to the air flow rate to be supplied to the IPU.

A vehicle ambient air purification arrangement, a vehicle, a vehicle fleet and a method for purifying air ambient to a vehicle are provided. The arrangement comprises an air conveying apparatus and a controller. The controller is arranged to control the air conveying apparatus to convey ambient air through ducts and filters of a ventilation system in response to a determination that an engine is inoperative and that a voltage supplied to the arrangement from an electricity supply source exceeds a threshold voltage.

The vehicle includes an air conditioner, a temperature sensor configured to measure an indoor temperature of the vehicle, a camera configured to obtain an image data of a passenger, and a bio-signal sensor configured to measure a bio-signal of the passenger. A controller is configured to control, when a predetermined condition is satisfied, the air conditioner to change a type of wind blowing at predetermined time intervals, to obtain emotion information corresponding to the changed type of wind based on at least one of the image data or the bio-signal, and to blow a type of wind for which a degree of positiveness of emotion information is equal to or greater than a threshold level.

A forced-ventilation device ventilates a compartment of a vehicle by forced ventilation by actuating a blower of an air-conditioning device of the vehicle when the compartment is left at a high temperature. When a mode for forced ventilation has been set by the user, when a mobile device approaching the vehicle together with a user enters a predetermined detection area within which the mobile device is detectable by a response signal, and when the response signal is successfully verified, a control portion switches ON an ignition switch of the vehicle, opens one or two or more windows using an opening and closing mechanism, and directs the air-conditioning device to actuate the blower.

A cooling device includes a duct, a passageway, and a plurality of nozzles spaced around the duct. The duct is sized to extend around at least a portion of the dome. The passageway may extend through the duct. The plurality of nozzles may be spaced around the duct and have first openings oriented toward the passageway and second openings oriented toward the surface.

A system and method monitor the interior of a vehicle, in particular a parked vehicle. A detection unit is designed to detect a living being in an interior of the vehicle. At least one control unit is designed to actuate at least one vehicle function in order to influence at least one environmental condition in the interior of the vehicle if: the detection unit detects a living being in the interior of the vehicle, and the at least one environmental condition in the interior of the vehicle exceeds or falls below at least one predetermined threshold value; and/or the control unit is designed to actuate at least one vehicle function in order to influence at least one environmental condition in the interior of the vehicle if: the detection unit detects a living being in the interior of the vehicle, and the at least one environmental condition in the interior of the vehicle exhibits a rise or fall.

An air-conditioning unit for a vehicle includes an air conditioning case, a blower, and a rectifying mechanism. The blower has a blower fan rotating around a fan axis and arranged in an in-case passage of the air conditioning case, and blows out air drawn from one side in an axial direction of the fan axis by rotation of the blower fan. The rectifying mechanism is arranged downstream of the blower fan in the in-case passage, and the air passes through the rectifying mechanism. The blower fan is arranged so that the other side of the fan axis that is opposite to the one side extends toward a downstream side of the in-case passage. The rectifying mechanism suppresses a swirling flow generated by the rotation of the blower fan in the air blown out from the blower fan as compared with the blown-out air prior to flowing into the rectifying mechanism.
