An air extraction system is provided for a motor vehicle. That air extraction system includes an air extractor having an air flow control valve and an actuator operatively connected to the air flow control valve. Further the system includes a controller configured to activate the actuator and open the air flow control valve when a closure of the motor vehicle is opened thereby mitigating a vacuum-effect otherwise created in the passenger cabin of the motor vehicle. Such a system is particularly effective in mitigating moon roof draw down on moon roof equipped motor vehicles. A related method is also provided.

The invention provides an alternative electrical charging system for a vehicle which is at least partially powered by electricity. The system employs a wind driven generator which produces electricity in response to air motion. When the generator is operating, electricity is communicated the battery of the vehicle. Operation of the generator involves a controller that monitors the electrical status of the battery and selectively activates a fan or opens a ducting system communicating with the generator. The controller also, in some embodiments, monitors the motion and the attitude of the vehicle.

Proposed is system and method for determining a driver's fatigue to promote safe driving by determining the driver's fatigue according to a change in a brain wave of a driver during driving of a vehicle.

A temperature control system includes a battery; a power electronics device that converts high-voltage electric power; an air passage; an inside-air intake passage and an outside-air intake passage that acquire inside air and outside air of a vehicle, and supply the airs to the air passage; an intake opening/closing member that opens and closes between the air passage and each of the intake passages; a passage switch that switches among a power-electronics prioritized state, a battery prioritized state, and a retention state; and a control device including a processor and a memory coupled to the processor. In a state in which a temperature of the outside air is lower than a battery lower limit temperature, the processor performs switching control of a power-electronics prioritized state, a battery prioritized state, and a retention state with the passage switches, based on an output value of the power electronics device.

A temperature control system includes an air-cooling target unit, an air passage in which the air-cooling target unit is disposed and through which air that exchanges heat with the air-cooling target unit flows, an inside-air intake passage, an outside-air intake passage, an intake opening/closing member, and a control device including at least one processor and at least one memory coupled to the processor. The processor performs a process including: determining whether transition of a temperature of the air-cooling target unit is in a rising trend; performing an intake air determination process of determining which of inside air and outside air is to be introduced into the air passage when the transition of the temperature of the air-cooling target unit is in the rising trend; and refraining from performing the intake air determination process when the transition of the temperature of the air-cooling target unit is not in the rising trend.

An air conditioning device for a vehicle includes a door control unit that controls multiple blowing port doors or an air mix door to prevent a heat generated from a heater core from leaking out of an air conditioning case before air conditioning of a vehicle interior is determined to be started. The air conditioning device includes an air conditioning control unit that performs the air conditioning of the vehicle interior by controlling the multiple blowing port doors to open at least one of multiple blowing ports and blow out a heat in the air conditioning case as hot air to the vehicle interior from the at least one blowing port after the air conditioning in the vehicle interior is determined to be started.

A method for natural ventilation of a vehicle interior includes steps of: determining, by a controller, formation of an interior negative pressure in an interior space while driving of a vehicle is maintained as an internal air mode, determining, by the controller, an over-production of a harmful gas in an exhaust gas using an air-to-fuel ratio or an Accelerator Position Scope (APS), in an air conditioning system; regarding satisfaction of the formation of the interior negative pressure and satisfaction of the over-production of the harmful gas as an entry condition and mixing an exterior air into the interior space so as to mitigate the interior negative pressure in the internal air mode; and after mixing the exterior air, regarding the non-satisfaction of the over-production of the harmful gas as a cancellation condition and blocking the exterior air.

A system according to the present disclosure includes a start-stop module, a bypass valve control module, and a flapper valve control module. The start-stop module is configured to stop an engine of a vehicle independent of an ignition system of the vehicle. The bypass valve control module is configured to adjust a bypass valve to a bypass position to prevent engine coolant from flowing from the engine to a heater core of the vehicle when the engine is stopped independent of the ignition system. The flapper valve control module is configured to control a flapper valve to adjust an amount of airflow from an evaporator of the vehicle to a cabin of the vehicle through the heater core.

An air conditioner for a vehicle including a case body having a floor outlet, a roof outlet, an evaporator, and a heater core; a mode door adjusting an opening amount of each of the vents; and a temp door adjusting an opening amount of a cold-air passage and a hot-air passage, includes: an actuator lever connected to an actuator provided in the case body, and a main lever connected to the actuator lever to simultaneously control the mode door and the temp door.

A vehicle air control system includes a vehicle body that defines an interior. A first particulate matter sensor is coupled to an exterior of the vehicle body. A second particulate matter sensor is disposed within the interior of the vehicle body. A temperature sensor is coupled to the exterior of the vehicle body. A vehicle speed sensor is coupled to the vehicle body. A heat, ventilation, and air condition (HVAC) system is disposed within the interior of the vehicle body. The HVAC system includes an inlet door rotatable between a first position, a second position, and a third position therebetween. A controller is configured to receive a signal from at least one of the first and second particulate matter sensors, the temperature sensors, and the vehicle speed sensor. The controller is configured to rotate the inlet door in response to the signal.
