A control device that controls an ultraviolet emission device such that the inside of a vehicle is sterilized is provided. The control device includes a vehicle state acquiring unit configured to acquire a state of the vehicle, a determination unit configured to determine whether a person is present inside of the vehicle based on the state of the vehicle, and a control unit configured to control the ultraviolet emission device with reference to a result of determination of whether a person is present inside of the vehicle.

A system for cleaning a compartment includes a conductive thread incorporated near a surface that has microbes on it. An electric current may flow through the conductive thread to kill the microbes on the surface through low-frequency electromagnetic pulse sterilization of the surface. The conductive trace is also in contact with air in the compartment. The electric current flowing through the conductive trace also ionizes the air within the compartment, which produces charged particles that are removed from the air.

An autonomous vehicle (AV) implements a health protocol that may reduce pathogen transmission between users of the AV. The AV is equipped with a thermal sensor that captures a body temperature of a user. The AV compares the user's temperature to a threshold temperature, and if the user's temperature exceeds the threshold temperature, the AV performs checks to ensure that the user's planned trip follows current regulations or recommendations. For example, the AV confirms that the user is traveling between the user's home and a healthcare facility. If the trip is permitted, the AV enables the user to enter the AV. The AV may include a disinfectant system for disinfecting the passenger compartment or surfaces after the user exits the AV.

A sterilization system for a vehicle includes an outer housing configured to rotate about a first shaft and having an opening formed to face an interior space, an inner housing installed inside the outer housing, exposed to the interior space through the opening, configured to rotate about a second shaft, and having a light transmitting portion through which sterilizing light is transmitted, a light source embedded in the inner housing and configured to irradiate the sterilizing light toward the light transmitting portion, and a driver configured to rotate the outer housing and the inner housing to irradiate the sterilizing light to the interior space and to change an irradiation angle of the sterilizing light.

A system for bacteria irradiation from an occupant zone of a vehicle is provided. The system comprises an interior portion disposed in the occupant zone. The interior portion has one of a predetermined surface porosity and a predetermined surface roughness. The interior portion has phosphorescent paint for visual indication. The system further comprises a high energy visible (HEV) light source integrated within the interior portion. The HEV light source has an emission wavelength of between about 375 nm and about 425 nm. The HEV light source further provides a cumulative energy of between about 1 J/cm.sup.2 and about 50 J/cm.sup.2. The system further comprises a vehicle processor in communication with the HEV light source. The vehicle processor is configured to enable the HEV light source. The system further comprises a sensor in communication with the vehicle processor and configured to provide input on when to enable light source.

A system comprises a processor and a memory. The memory stores instructions executable by the processor to determine a baseline polarization for a surface of a material based on a first polarimetric image of the surface, to determine a second polarization for the surface based on a second polarimetric image of the surface, to determine, based on the baseline polarization data and the second polarization data, that there is a wet area on the surface, and upon determining the wet area, actuate an actuator to cause a clean the surface.
