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.

An air-conditioning control system includes an air-conditioning device mounted in a host vehicle, a determination unit mounted in the host vehicle or a server and configured to determine whether a boarding position at which a boarding event in which an occupant boards the host vehicle occurs is a point with a predetermined attribute, and a control unit mounted in the host vehicle and configured to control the air-conditioning device based on a determination result from the determination unit. The control unit sets a ventilation capacity of the air-conditioning device to be greater when the determination unit determines that the boarding position is a point with the predetermined attribute than when the determination unit does not determine that the boarding position is a point with the predetermined attribute.

An apparatus and method for controlling air conditioning of a vehicle are provided. The apparatus includes a sensing device that measures a pollutant concentration and a carbon dioxide concentration in the vehicle using at least one sensor. A controller determines an in-vehicle air condition based on the pollutant concentration and the carbon dioxide concentration, and automatically switches an in-vehicle air circulation mode based on a determination result.

A system and method for robust automatic control of an air-conditioning system in a vehicle includes at least one sensor configured to continuously capture technical driving parameters of the vehicle. The system has a computing unit configured to determine a current air quality from the captured technical driving parameters by way of a suitable algorithm. The system has a control unit configured to control the air-conditioning system in the vehicle, wherein the control of the air-conditioning system includes activating the recirculation circuit of the air-conditioning system and/or activating the fresh-air circuit of the air-conditioning system with reference to the determined air quality.

A motor-vehicle includes one or more electrically-operated valves, arranged on the structure of the motor-vehicle in a lower position with respect to the windows, for providing a communication between a passenger compartment and the external environment, and one or more electronic control units programmed to activate a ventilation mode of the passenger compartment when the motor-vehicle is parked with the engine off, even with the driver outside the vehicle. The ventilation mode includes controlling at least partial opening of one or more windows and the opening of one or more of the valves to generate a flow of natural air from the bottom upwards through the passenger compartment of the motor-vehicle.

An exhaust intrusion mitigation system for a vehicle includes one or more processors and a memory communicably coupled to the one or more processors. The memory stores an enclosure detection module which determines if a vehicle is parked within an enclosure with the engine running. An exhaust module determines a point in time at which one or more vehicle vents should be closed if the vehicle remains in the enclosure and the engine remains on. A mitigation module controls operation of the vehicle to close the one or more vents at the point in time when the vent(s) should be closed.

An air conditioning system of a vehicle and a control method thereof, includes a distance sensor that is configured to detect a distance from the vehicle to another vehicle in front of the vehicle; a humidity sensor that is configured to detect an inside humidity of the vehicle; an inside temperature sensor that is configured to detect an inside temperature of the vehicle; an outside temperature sensor that is configured to detect an outside temperature of the vehicle; and a controller electrically connected to the distance sensor, the humidity sensor, the inside temperature sensor, and the outside temperature sensor and configured for determining an air conditioning mode of the vehicle based on the distance to another vehicle in front detected by the distance sensor, the inside humidity of the vehicle detected by the humidity sensor, the inside temperature of the vehicle detected by the inside temperature sensor, and the outside temperature of the vehicle detected by the outside temperature sensor.

An air-conditioning control system includes: a weather acquisition unit configured to obtain weather information including a weather forecast; a prediction unit configured to predict, based on the weather information, an amount of change in a quantity of water droplets adhering to an evaporator of an air conditioner installed in a vehicle; and a switching control unit configured to control switching of an inside/outside air switching mechanism of the air conditioner based on the amount of change, the inside/outside air switching mechanism switching air delivered to an interior of the vehicle to one of inside air and outside air, the inside air being air in the interior of the vehicle, the outside air being air outside the vehicle.

An air-conditioning apparatus for a vehicle and a control method of the same are provided which may inhibit a closing degree of a door from being insufficient even when the door is closed while a blower fan is actuated. An air-conditioning apparatus for a vehicle includes an inside-outside air switching damper including a damper switching actuator, a blower fan, a control unit, and door opening-and-closing sensors. In a case where the door becomes an open state and a case where the blower fan is actuated and the inside-outside air switching damper is in an outside air introduction mode, the control unit issues a command to the damper switching actuator to switch the inside-outside air switching damper to an inside air circulation mode.
