An air conditioning device for a vehicle is provided in which air cleaning control can be executed to reduce a concentration of floating particulate substances in a vehicle cabin by increasing an air volume passing through a filter by further increasing an air volume blowing out from a blower outlet into the vehicle cabin from an air volume which is necessary for cabin temperature control or an air volume which is set by a passenger of the vehicle, and in which, under an air conditioning condition in which an increase of the cabin temperature is strongly demanded, when a fluid temperature of a fluid which is a heat source of indoor heating is lower than a predetermined fluid temperature, an upper limit value permitted as an amount of increase of an air volume by the air cleaning control is inhibited.

A ventilation system for a mobile structure, in particular a motor vehicle, includes: a variably adjustable filter device including at least one controllable, variable filter characteristic with regard to a pollutant class; means for collecting information about the air quality in the surroundings of the mobile structure and in particular information about the air quality in an interior of the mobile structure; and a control unit for varying filter characteristics of the filter device in a variable, in particular continuous, manner, on the basis of the information about the air quality.

An automatic ventilation system and method for vehicle are disclosed. The system includes: a ventilator to control a ventilation operation of an indoor space of a second vehicle; an input unit to receive information of automatic ventilation for a first vehicle, the automatic ventilation automatically performed based on a change in CO.sub.2 concentration inside the first vehicle; and a controller to determine an initiation time point of an automatic ventilation operation of the second vehicle based on the received automatic ventilation information and to control the ventilator to ventilate the indoor space of the second vehicle at the determined initiation time point, thereby pleasantly ventilating an indoor space of the second vehicle with reference to data related to an automatic ventilation operation of first vehicle including a CO.sub.2 sensor.

A mechanism is provided for controlling the internal air-quality of a vehicle, including determining a changing trend of the in-vehicle air-quality based on acquired in-vehicle sensor data and usage status of the vehicle and responsive to the determined changing trend of the in-vehicle air-quality, signaling a control system of the vehicle to control the usage status of the vehicle based on a control policy.

Provided herein is a system on a vehicle, the system comprising one or more sensors configured to monitor concentrations of each of one or more chemicals in an interior of a vehicle, one or more processors, and a memory storing instructions that, when executed by the one or more processors, causes the system to perform: one or both of ventilating the interior of the vehicle and applying heat in the interior of the vehicle in response to one or more of the concentrations being higher than respective thresholds; in response to the performing one or both of ventilating and applying the heat in the interior of the vehicle, cleaning the interior of the vehicle in response to determining that any of the one or more of the concentrations remain higher than the respective thresholds.

A waste service management system, method, and computer program product improve waste services by responding to air quality that is outside and inside a waste service vehicle. A controller monitors at least one exterior air quality sensor that is mounted to, and exposed to air exterior to, the waste service vehicle. The controller monitors at least one interior air quality sensor that is mounted to the waste service vehicle and exposed to air interior to a waste hauling body that is one of carried and attached to the waste service vehicle. The controller compares measurement levels of exterior and interior airborne chemical constituents to one or more corresponding air quality thresholds. The controller presents a notification on a user interface device indicating any exceedance of the air quality threshold and an associated origin of one of the exterior air and the interior air.

An air conditioning system provides inside air conditioning and performs the function of cleaning the inside air, so that the inside air is maintained to be pleasant. The air cleaning time of cleaning the inside air is decreased, so the possibility of moisture generated on an inside window due to the air cleaning is reduced.

This system (1) includes an air intake (5) outside the cabin (2), a filter (8), and a turbine (10) for supplying pressurized air to the cabin (2). According to the invention: the air intake (5) is the one used to supply the engine of the vehicle with air; the system (1) includes an air intake duct (6) connected directly to the air delivery duct (7) extending between the air filter (8) of the engine of the vehicle and the engine or turbo compressor (9) with which the engine is equipped; and the turbine is a multi-stage turbine (10) which is capable of generating a depression greater than the maximum depression value likely to exist in the air delivery duct (7) depending on the clogged state of the air filter of the engine (8), the speed of the engine and the load on the engine.

An air purge method in a vehicle is provided. The air purge method comprises starting a vehicle ventilation device in response to ventilation instruction; determining a current air purge status based on an operation time of the ventilation device; and indicating the current air purge status via an air purge indication device.

An imaging system connected to an occupant monitoring system includes communications with an apparatus for measuring gas or airborne compound concentrations in a vehicle cabin. The apparatus includes a housing configured as a flow tube in fluid communication with ambient air in the vehicle cabin. A spectrometer is mounted within the housing and subject to ambient air flow through the housing, and the spectrometer is connected to a light source and receives reflected light from the air flow to detect by spectrum analysis the concentration of target gases and/or airborne compounds. The spectrometer identifies spectral changes in the light and reflected light within the ambient air flow. The spectrometer communicates with computerized vehicle control systems, and runs software stored to calculate the concentration of target gases and/or airborne compounds from the spectral changes.
