US 11,692,933 B2 · Systems and methods of ambient gas sensing in a vehicle

Abstract

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.

Dependent claims

A system for measuring gas or airborne compound concentration in a vehicle cabin comprising:

a 3D infrared time of flight camera having a field of view encapsulating at least a portion of a vehicle cabin and emitting light into the field of view,
a processor communicatively coupled to a computerized memory;
wherein the 3D infrared time of flight camera collects image data comprising a 3D view from the field of view, wherein the 3D view is created by light reflected back to the 3D infrared time of flight camera from a gas in the ambient air or an airborne particle in the ambient air;
wherein the computerized memory comprises software that uses the image data to calculate identification data regarding the gas and/or airborne particle in the ambient air, and wherein the processor is configured to transmit the identification data to a vehicle computer system;
wherein the vehicle computer system uses the identification data to trigger at least one remedial action for neutralizing the presence of the gas and/or airborne particle in the ambient air.
