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.

Systems and methods are disclosed for supporting and executing automated control of climate comfort settings based on user classification within a group identity database. Methods of generating and employing the group identity database are also disclosed.

Provided herein is a system and method for regulating a sensor enclosure of a vehicle. The system comprises an enclosure comprising a vent at a base of the enclosure, one or more sensors configured to determine a parameter of the vehicle or the enclosure, a fan configured to regulate an internal temperature of the enclosure, and a controller configured to regulate a rotation speed of the fan based on the parameter of the vehicle or the enclosure. The regulating system further comprises a deflector connected to the enclosure and configured to direct an airflow into the vent based on the parameter.

A climate control system for a vehicle includes a front-end or first heat exchanger configured to thermally condition airflow from an environment external to a vehicle cabin, a rear-end or second heat exchanger configured to thermally condition airflow from the vehicle cabin, a recirculation path configured to return airflow from the second heat exchanger to the vehicle cabin, and an extraction path configured to vent airflow from the second heat exchanger to the environment external to the vehicle cabin. Various operational modes of the climate control system direct airflow to either the recirculation path or the extraction path.

Embodiments herein relate to vehicle filter monitoring systems and methods. In an embodiment, a filter monitoring system is included having a filter sensor device configured to generate data reflecting a filter condition value of a filter and a geolocation circuit configured to determine a present geolocation of a vehicle. The system can also include a system control circuit configured to generate or receive local contaminant concentration values at the present geolocation, evaluate the filter sensor device data to determine at least one of the filter condition value and a change in the filter condition value, and generate at least one of a maintenance recommendation and a routing recommendation based on the local contaminant concentration values, time spent at the geolocation of the vehicle, duty cycle of the vehicle, the filter condition value, and a change in the filter condition value. Other embodiments are also included herein.

A cabin air state sensing system for a vehicle may include a divergence structure facilitating measurement of cabin air temperature and dust concentration in a cabin through suction of air using an air suction device and an operation method thereof.

An air quality system includes an air precleaner, a filter identification component, and a control module. The air precleaner has a precleaner housing and a filter disposed inside the precleaner housing. The filter identification component is positioned within the precleaner housing at a first position and is mounted on the filter. The control module is positioned within the precleaner housing at a second position and is configured to emit an electrical field and communicate with the filter identification component via the emitted electrical field.

Provided is an air-conditioning system including: an air pollution level detector configured to detect each of a pollution level of outside air, which is air outside a vehicle, and a pollution level of inside air, which is air inside the vehicle; and an air-conditioning control device configured to control air conditioning by switching an air-conditioning mode of the vehicle between an inside-air circulation mode and an outside-air introduction mode. The air-conditioning control device switches the air-conditioning mode from the outside-air introduction mode to the inside-air circulation mode based on the pollution level of the outside air acquired from the air pollution level detector, and switches the air-conditioning mode from the inside-air circulation mode to the outside-air introduction mode based on the pollution level of the inside air acquired from the air pollution level detector.

A method and a device for detecting odor nuisances along a route of a subject transportation vehicle and for predictively initiating measures for preventing the penetration of the odorants of the odor nuisance into the subject transportation vehicle during travel. The method includes collecting swarm data from a plurality of swarm transportation vehicles in the surroundings of the route of the subject transportation vehicle, relating to the odor nuisance of each swarm transportation vehicle, ascertaining locations of an odor nuisance from the collected swarm data, ascertaining the extent of the odor nuisance around the respective location of the odor nuisance, and initiating measures in the subject transportation vehicle when approaching the location of an odor nuisance while taking into account the extent of the odor nuisance along the future route, wherein the measure is implemented at a predefined distance from the extent of the odor nuisance.

A passenger transport vehicle, such as a rail vehicle, has at least one sanitary module and at least one fan for conveying waste air from the sanitary module. A control unit controls the volumetric flow of waste air from the sanitary module. The control unit is formed for at least two volumetric flows of waste air, which differ from one another and differ from zero. The volumetric flows are conveyed by the at least one fan, at least on the basis of a state of the sanitary module.
