Abstract

This document describes self-sanitizing systems that sanitize the cabins of vehicles. In one aspect, a method includes initiating a sanitizing cycle for sanitizing one or more surfaces of one or more components of a vehicle cabin. During the sanitizing cycle, one or more UV light sources are activated, and at least one of a shape, a position, or orientation of the surface is adjusted with respect to the one or more UV light sources. The sanitizing cycle is terminated.

Claims (53)

1. A method, comprising:

initiating a sanitizing cycle for sanitizing one or more surfaces of one or more components of a vehicle cabin;

during the sanitizing cycle:

activating one or more ultraviolet (UV) light sources configured to illuminate at least a portion of each of the one or more surfaces; and

adjusting at least one of a shape, a position, or an orientation of at least one surface of the one or more surfaces with respect to the one or more UV light sources, wherein by adjusting the shape of the at least one surface with respect to the one or more UV light sources one or more actuation zones of the at least one surface are activated, and wherein each actuation zone of the one or more actuation zones comprises a plurality of cells that adjust the shape of the at least one surface multiple times during the sanitizing cycle; and

terminating the sanitizing cycle based on the adjustment.

2. The method of claim 1 , wherein the one or more UV light sources comprise one or more far-UVC light sources.

3. The method of claim 1 , wherein initiating the sanitizing cycle comprises:

detecting a change of state event indicating (i) that an occupant of the vehicle cabin has departed the vehicle cabin and (ii) a change of state from a clean vehicle cabin to a dirty vehicle interior; and

initiating the sanitizing cycle in response to detecting the change of state event.

4. The method of claim 3 , wherein detecting the change of state event comprises detecting that a color of thermochromic material of the at least one surface is within a specified color range.

5. The method of claim 1 , wherein initiating the sanitizing cycle comprises detecting that a sanitizing zone that comprises the one or more surfaces is unoccupied.

6. The method of claim 1 , wherein terminating the sanitizing cycle comprises:

detecting that a color of photochromic material of the at least one surface is within a specified color range; and

terminating the sanitizing cycle in response to detecting that the color of the photochromic material of the at least one surface is within the specified color range.

7. The method of claim 1 , wherein adjusting at least one of the shape, the position, or the orientation of the at least one surface with respect to the one or more UV light sources comprises:

determining that an area of the at least one surface of a component of the one or more components has not been sufficiently sanitized; and

adjusting the orientation or the position of the component such that the area is illuminated by the one or more UV light sources.

8. The method of claim 1 , further comprising:

detecting a contaminant on the at least one surface; and

generating a notification that indicates that the vehicle cabin is in an unclean state, wherein the notification indicates one or more recommended manual interventions to clean the vehicle cabin.

9. A system, comprising:

one or more processors; and

one or more memory devices interoperably coupled with the one or more processors and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:

initiating a sanitizing cycle for sanitizing one or more surfaces of one or more components of a vehicle cabin;

during the sanitizing cycle:

activating one or more ultraviolet (UV) light sources configured to illuminate at least a portion of each of the one or more surfaces; and

adjusting at least one of a shape, an orientation, or a position of at least one surface of the one or more surfaces with respect to the one or more UV light sources, wherein by adjusting the shape of the at least one surface with respect to the one or more UV light sources comprises activating one or more actuation zones of the at least one surface are activated, and wherein each actuation zone of the one or more actuation zones comprises a plurality of cells that adjust the shape of the at least one surface multiple times during the sanitizing cycle; and

terminating the sanitizing cycle based on the adjustment.

10. The system of claim 9 , wherein the one or more UV light sources comprise one or more far-UVC light sources.

11. The system of claim 9 , wherein initiating the sanitizing cycle comprises:

detecting a change of state event indicating (i) that an occupant of the vehicle cabin has departed the vehicle cabin and (ii) a change of state from a clean vehicle cabin to a dirty vehicle interior; and

initiating the sanitizing cycle in response to detecting the change of state event.

12. The system of claim 11 , wherein detecting the change of state event comprises detecting that a color of thermochromic material of the at least one surface is within a specified color range.

13. The system of claim 9 , wherein initiating the sanitizing cycle comprises detecting that a sanitizing zone that comprises the one or more surfaces is unoccupied.

14. The system of claim 9 , wherein terminating the sanitizing cycle comprises:

detecting that a color of photochromic material of the at least one surface is within a specified color range; and

terminating the sanitizing cycle in response to detecting that the color of the photochromic material of the at least one surface is within the specified color range.

15. The system of claim 9 , wherein adjusting at least one of the shape, the orientation, or the position of the at least one surface with respect to the one or more UV light sources comprises:

determining that an area of the at least one surface of a component of the one or more components has not been sufficiently sanitized; and

adjusting the orientation or the position of the component such that the area is illuminated by the one or more UV light sources.

16. The system of claim 9 , wherein the operations comprise:

detecting a contaminant on the at least one surface; and

generating a notification that indicates that the vehicle cabin is in an unclean state, wherein the notification indicates one or more recommended manual interventions to clean the vehicle cabin.

17. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

initiating a sanitizing cycle for sanitizing one or more surfaces of one or more components of a vehicle cabin;

during the sanitizing cycle:

activating one or more ultraviolet (UV) light sources configured to illuminate at least a portion of each of the one or more surfaces; and

adjusting at least one of a shape, an orientation, or a position of at least one surface of the one or more surfaces with respect to the one or more UV light sources, wherein by adjusting the shape of the at least one surface with respect to the one or more UV light sources one or more actuation zones of the at least one surface are activated, and wherein each actuation zone of the one or more actuation zones comprises a plurality of cells that adjust the shape of the at least one surface multiple times during the sanitizing cycle; and

terminating the sanitizing cycle based on the adjustment.

18. The non-transitory, computer-readable medium of claim 17 , wherein initiating the sanitizing cycle comprises:

detecting a change of state event indicating (i) that an occupant of the vehicle cabin has departed the vehicle cabin and (ii) a change of state from a clean vehicle cabin to a dirty vehicle interior; and

initiating the sanitizing cycle in response to detecting the change of state event.
