A vehicle system includes: a blower configured to draw air from within a passenger cabin of a vehicle through an inlet; a binding agent source configured to flow a binding agent into the air; and a sensor disposed downstream of the binding agent source in the direction of airflow, the sensor configured to determine an amount of smoke in the air from within the passenger cabin based on a measured characteristic of particulate at the sensor and a predetermined characteristic of the binding agent.

A vehicle air monitoring system includes a housing defining an interior and an inlet. An airflow assembly is disposed within the interior and includes a pump configured to draw an air sample into an airflow passage via the inlet. A detection assembly is in fluid communication with the airflow passage of the airflow assembly. The detection assembly includes a light source configured to illuminate a biochip and a photodetector configured to detect an optical transmission of the biochip based on a photocurrent of the photodetector. A control assembly is in communication with the airflow assembly and the detection assembly.

This disclosure is generally directed to systems and methods for protecting the health of occupants of a vehicle. In an example method, a health monitoring apparatus in a vehicle evaluates an individual and detects a symptom of a contagious disease. The individual may be already seated in a first seat in the vehicle or intends to enter the vehicle. The health monitoring apparatus identifies a second seat that has a pre-defined spatial separation distance from the first seat. The pre-defined spatial separation distance can exceed a threshold spatial separation distance selected to provide health protection against the contagious disease. The health monitoring apparatus issues an advisory to the individual to occupy the second seat. In another example method, the health monitoring apparatus may adjust an airflow pattern in the vehicle so as to provide directional airflows to protect various occupants of the vehicle against an airborne contagious disease.

For the purpose of gas quality monitoring, a spectroscopic examination of a gas sample from a space (10) to be monitored is carried out, e.g. by Raman spectroscopy. The spectroscopic examination yields a measurement spectrum extending over a wavelength range. A deviation of the measurement spectrum from at least one comparison sample (160) is then detected. Depending on the detected deviation, a gas quality warning (QW) is produced.

An air quality system for a vehicle includes a chemical detection apparatus including a plurality of nanofiber chemical sensors for sensing a plurality of airborne materials in a compartment of the vehicle. The plurality of nanofiber chemical sensors are configured to adjust a characteristic electrical signal in response to changes in the presence of the plurality of airborne materials. The chemical detection apparatus further includes a processor coupled to the nanofiber chemical sensor, wherein the processor is configured to monitor the characteristic electrical signals from the nanofiber chemical sensors and generate a detection signal in response to a change in the characteristic electrical signals. The processor is in communication with a controller configured to control at least one vehicle system in response to the detection of one or more of the airborne materials.

The present invention relates to a breath analyzing system and method. In particular the invention relates to a breath analyzing system combined with a heat, ventilation and air conditioning system (HVAC-system) of the vehicle, wherein the settings of the HVAC system are controlled to optimize the performance of the breath analyzing system. In particular the HVAC system may be set to a closed position facilitating a concentration build up of breath gases in the compartment. Alternatively the HVAC system may shift between open and closed positions.

A method of operating a vehicle climate system when an ambient temperature is below a threshold temperature is provided. In response to an ambient temperature being less than a threshold temperature, a controller is adapted to operate a blower motor at a voltage that depends on whether the vehicle is in charge sustain mode or charge deplete mode. The controller operates the blower motor according to a first voltage responsive to a charge sustain mode, and operates the blower motor according to a second voltage different than the first voltage in response to a charge deplete mode.

An apparatus and a method for controlling a vehicle, which control a route of the vehicle or an air circulation mode of the vehicle based on an outdoor air condition of an autonomous driving vehicle and control an indoor air cleaner of the vehicle based on an indoor air condition. In some implementations, an apparatus for controlling a vehicle includes an outdoor measurement sensor attached to an exterior of the vehicle and measuring an external fine dust concentration, a communicator receiving, from an environment server, a local fine dust concentration corresponding to a position of the vehicle, and when a difference between the measured external fine dust concentration and the received local fine dust concentration exceeds a set allowance, a controller checking whether an object generating fine dust exists outside the vehicle and allowing the vehicle to travel while avoiding the object when it is confirmed that the object exists.

A method of preventing exhaust gas intrusion in a passenger compartment of a vehicle is provided. Whether a vehicle operating condition resulting in an increased carbon monoxide emission at an exhaust pipe is present is detected. Whether a vehicle component condition is present is detected. The vehicle component condition is an open window or an open sunroof. An HVAC setting is switched from a recirculating air mode to a fresh air mode when at least one of the vehicle operating condition and the vehicle component condition is detected as being present.
