A vehicle system includes: an olfaction sensor comprising: a blower configured to draw air through an inlet; a filter configured to filter particulate from the air; and a volatile organic compounds (VOC) sensor disposed downstream of the filter and configured to measure an amount of VOCs in air after the air flows through the filter; and a control module configured to selectively take one or more remedial actions based on the amount of VOCs.

The present disclosure discloses an infrared sensor, an infrared gas detector and an air quality detection device. The infrared sensor includes electrodes, a substrate, an isolation layer and a graphene film. The graphene film has a periodical nanostructure. The infrared sensor enhances the absorption of infrared light, and is capable of only absorbing specific infrared wavelengths, thus improving the selective performance of the infrared gas detector.

An interior ventilation system for a motor vehicle includes an air measurement chamber, into which outdoor air of the motor vehicle can be fed via an outside air supply line and vehicle interior air of the motor vehicle can be fed via an inside air supply line, air quality sensors for measuring a harmful-substance content in air located in the air measurement chamber, and a measurement air control unit, which is designed to selectively supply outdoor air and/or vehicle interior air to the air measurement chamber. A motor vehicle includes such an interior ventilation system.

Described herein is a system and method for detecting malodor within a cabin of an autonomous vehicle, wherein initiation of a remediation system and/or dispatch of the autonomous vehicle to a service hub for mitigating the malodor is based upon sensor signals that monitor the cabin of the autonomous vehicle. The remediation system can include devices such as an HVAC system or a window, which are operated to reduce the concentration of airborne molecules in the cabin of the autonomous vehicle when the concentration of airborne molecules exceeds an air quality threshold. A dispatch protocol may be initiated to dispatch the autonomous vehicle to a service hub when the malodor is associated with certain predefined incidents or when remediation fails to reduce the concentration of airborne molecules below the air quality threshold.

A vehicle gas-detecting device includes a control unit, a gas-detecting unit, a warning unit, and a power-connecting unit. The gas-detecting unit is electrically connected to the control unit. The gas-detecting unit detects the concentration of a gas in a vehicle. The warning unit is electrically connected to the control unit. The power-connecting unit is electrically connected to the control unit and a power source of the vehicle. Thereby, when the concentration of the gas within the vehicle is greater than a predetermined threshold, the control unit activates the warning unit to give a warning to draw users' attention.

Methods and apparatus for vehicle HVAC control are disclosed. A disclosed example apparatus includes a portable device interface of a vehicle, the portable device interface to be communicatively coupled with a portable device, a heating, ventilation and air conditioning (HVAC) control system of the vehicle, where the HVAC control system is to be communicatively coupled to the portable device interface. The example apparatus also includes a processor to control the HVAC control system based on signals received at the portable device interface from the portable device.

A system includes a blower, a blower sensor, and at least one processor. The blower sensor is operably coupled to the blower and configured to obtain blower operational information. The at least one processor is operably coupled to the blower and the blower sensor, and is configured to determine an operational-based power using the blower operational information; determine an operational-based density using the operational-based power; and control the blower using the operational-based density.

A smart multi-modal vehicular air filtration management system including a first filter element and a second filter element disposed in a fresh air housing, wherein the fresh air housing has an inlet and an outlet. Additionally, a third filter element is provided which is disposed in a cabin housing, the cabin housing having one or more inlet. A fluid channel arranged between the fresh air and cabin housing. Finally, a diverter is included which is disposed near an outlet of the fresh air housing, wherein the diverter is configured to cause air to flow through the fresh air housing selectively through one or both of the first filter element and the second filter element.

A system for ventilating a vehicle interior compartment operates, at least intermittently, to set an air quality mode in which fresh air and/or circulated air is supplied to the vehicle interior compartment, and to control an interior compartment pressure in the vehicle interior compartment through variation of the flow resistance of an interior compartment ventilation device in an open-loop and/or a closed-loop manner such that the interior compartment pressure is higher than an ambient pressure outside the vehicle interior compartment.

A computer-implemented process for controlling a vehicle interior includes detecting a previously defined situation that relates to an undesirable environmental condition of the vehicle interior, and assessing both a risk level and an urgency level, based on a vehicle sensor input. The process also includes generating a vehicle command based upon the detected previously defined situation, the assessed risk level, and assessed urgency level, and executing the generated vehicle command to control at least one of an engine, a window, and a heating, ventilation and air conditioning (HVAC) unit to modify an environmental condition of the vehicle interior.
