A fogging suppression apparatus that suppresses fogging of a window of vehicle, comprises an acquisition unit that acquires an external temperature of the vehicle, a heater that heats the window, the heater differing from an air conditioning apparatus including a blower provided in the vehicle; and a control unit that controls the heater so as to heat the window when the external temperature of the vehicle is lower than or equal to a predetermined temperature and there is a request for activation of the air conditioning apparatus.

One or more embodiments described herein relate to a modular multifunctional system for a vehicle, and more specifically, to a versatile sensor system integrated into a modular overhead console. Multiple systems and functions are consolidated into particular overhead units to allow for increase space inside a vehicle, decreased design restrictions, and the use of a single type of modular overhead console in multiple vehicle types and models.

Upon detecting an absence of a user inside a passenger cabin of a vehicle, an object inside the passenger cabin is classified as one of preferred or nonpreferred. Upon classifying the object as preferred, a sensor is activated to monitor an environment outside the passenger cabin based on determining the object is visible from outside the passenger cabin. A priority level for the preferred object is determined based on data from the sensor, wherein the priority level is one of high or low. A vehicle component is actuated to reduce the priority level based on determining the priority level for the preferred object is high.

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.
