Abstract

Systems and methods are provided for automated detection and disinfection of microbes in autonomous vehicles, to prevent possible transmission of diseases or illness to subsequent users. Automated detection and disinfection of a vehicle includes autonomously scanning various parts of the autonomous vehicle for microbes, selecting a disinfectant based on detected microbes, and autonomously disinfecting at least a portion of the autonomous vehicle.

First claim

1 - 20 . (canceled)

21 . A system for automated detection and disinfection of microbes in an autonomous vehicle fleet, comprising:
the fleet of autonomous vehicles, each autonomous vehicle comprising:
a microbe detection unit coupled to the respective autonomous vehicle configured to autonomously perform microbe detection, wherein the microbe detection unit includes a scanning element configured to scan a plurality of parts of the respective autonomous vehicle for microbes;
an onboard computer in the respective autonomous vehicle configured to:
receive scans of the plurality of parts of the respective autonomous vehicle from the scanning element, and
determine whether microbes are detected on each of the plurality of parts; and

a disinfection system configured to autonomously disinfect at least one part of the plurality of parts of the respective autonomous vehicle wherein the at least one part includes detected microbes,
wherein the disinfection system is configured to autonomously disinfect for a predetermined time while the respective autonomous vehicle is driving along a route, and
wherein the disinfection system is configured to contact a routing coordinator to determine whether to add time for disinfection following the route; and

a central computer in communication with each autonomous vehicle of the fleet of autonomous vehicles, configured to:
receive microbe detection data from the fleet of autonomous vehicles, and determine fleet-wide levels of microbes.

22 . The system of claim 21 , wherein the onboard computer in each respective autonomous vehicle is further configured to identify a species of the microbes and select a disinfecting method based on the species of the microbes.

23 . The system of claim 22 , wherein the central computer is further configured to receive microbe detection data including identified species of microbes.

24 . The system of claim 23 , wherein the central computer is further configured to identify a plurality of disinfectants to carry on each vehicle, based on the fleet-wide data including identified species of microbes.

25 . The system of claim 24 , wherein each respective autonomous vehicle further comprises a plurality of storage tanks for storing the plurality of disinfectants.

26 . The system of claim 24 , wherein the plurality of disinfectants includes a plurality of disinfecting methods, wherein the disinfecting methods include an ultraviolet (UV) light source configured to emit UV light and spray elements configured to emit a disinfecting solution.

27 . A system for automated detection and disinfection of microbes in an autonomous vehicle, comprising:
a microbe detection unit coupled to the autonomous vehicle configured to autonomously perform microbe detection, wherein the microbe detection unit includes a scanning element configured to scan a plurality of parts of the autonomous vehicle for microbes; an onboard computer in the autonomous vehicle configured to:
receive scans of the plurality of parts of the autonomous vehicle from the scanning element, and
determine whether microbes are detected on each of the plurality of parts; and
a disinfection system configured to autonomously disinfect at least one part of the plurality of parts of the autonomous vehicle wherein the at least one part includes detected microbes,
wherein the disinfection system is configured to autonomously disinfect for a predetermined time while the autonomous vehicle is driving along a route, and
wherein the disinfection system is configured to contact a routing coordinator to determine whether to add time for disinfection following the route.

28 . The system of claim 27 , further comprising a plurality of storage tanks for storing different disinfecting solutions.

29 . The system of claim 28 , further comprising a plurality of spray elements coupled to the autonomous vehicle for emitting the disinfecting solutions,
wherein a first spray element is directed at a first part of the autonomous vehicle and a second spray element is directed at a second part of the autonomous vehicle, and wherein a first storage tank is connected to the first spray element and a second storage tank is connected to the second spray element.

30 . The system of claim 27 , wherein the onboard computer is further configured to receive fleet data including fleet-wide levels of microbes.

31 . The system of claim 27 , wherein the onboard computer is further configured to identify a species of the microbes and select a disinfecting method based on the species of the microbes.

32 . The system of claim 27 , further comprising an ultraviolet (UV) light source configured to emit UV light on the plurality of parts of the autonomous vehicle.

33 . The system of claim 32 , wherein the UV light source is configured to illuminate microbes on the plurality of parts of the autonomous vehicle.

34 . The system of claim 32 , wherein the UV light source is configured to disinfect microbes on the plurality of parts of the autonomous vehicle.

35 . The system of claim 27 , wherein the onboard computer is configured to identify selected parts of the plurality of parts having microbes, and the disinfection system is configured to disinfect the selected parts.

36 . A system for automated detection and disinfection of microbes in an autonomous vehicle fleet, comprising:
a plurality of autonomous vehicles, each autonomous vehicle comprising:
a microbe detection unit coupled to the respective autonomous vehicle configured to autonomously perform microbe detection;
an onboard computer in the respective autonomous vehicle configured to:
determine whether microbes are detected on each of the plurality of parts and
identify a species of the microbes; and

a disinfection system configured to autonomously disinfect at least one part of the plurality of parts of the respective autonomous vehicle wherein the at least one part includes detected microbes,
wherein the disinfection system is configured to autonomously disinfect for a predetermined time while the respective autonomous vehicle is driving along a route, and
wherein the disinfection system is configured to contact a routing coordinator to determine whether to add time for disinfection following the route.

a central computer in communication with each autonomous vehicle of the plurality of autonomous vehicles, configured to:
receive microbe detection data from the plurality of autonomous vehicles including identified species of microbes, and
identify high levels of microbes across the plurality of autonomous vehicles.

37 . The system of claim 36 , wherein the onboard computer in each respective autonomous vehicle is further configured to select a disinfecting method based on the species of the microbes.

38 . The system of claim 36 , wherein the central computer is further configured to identify a plurality of disinfectants to carry on each vehicle, based on the identified species of microbes.

39 . The system of claim 38 , wherein each respective autonomous vehicle further comprises a plurality of storage tanks for storing the plurality of disinfectants.

40 . The system of claim 36 , wherein the central computer is further configured to determine levels of each of the identified species of microbes across the plurality of autonomous vehicles.
