Abstract

Systems and methods are provided herein for operating an autonomous vehicle in the presence of hazardous materials. The autonomous vehicle is operated in travel along a selected route. A determination is made, using a sensor, that a hazardous material is present inside the autonomous vehicle during the operation of the autonomous vehicle. In response, a setting of the autonomous vehicle is changed to counteract the presence of the hazardous material inside the autonomous vehicle. Additionally, also in response, a modified route is calculated, the modified route addressing the presence of the hazardous material inside the autonomous vehicle. Then, the autonomous vehicle is operated to travel along the modified route.

First claim

What is claimed is:

1. A method for operating an autonomous vehicle, the method comprising:
operating the autonomous vehicle to travel along a selected route;
determining, using a sensor, an amount of hazardous material inside the autonomous vehicle during the operation of the autonomous vehicle; and
in response to determining that the amount of hazardous material exceeds a first threshold:
changing a setting of the autonomous vehicle to counteract a presence of the hazardous material inside the autonomous vehicle;
calculating a modified route, wherein the modified route addresses the presence of the hazardous material inside the autonomous vehicle;
operating the autonomous vehicle to travel along the modified route; and
displaying an override option, wherein activation of the override option cancels the setting change and causes the autonomous vehicle to travel along the selected route; and
in response to determining that the amount of the hazardous material in the autonomous vehicle subsequently exceeds a second threshold, removing the display of the override option.

2. The method of claim 1 , wherein the hazardous material is a human-generated biohazardous material, wherein a human-generated biohazardous material comprises at least one of human vomit, human blood, human stool, and human urine.

3. The method of claim 1 , wherein the sensor comprises a gas analyzer, and wherein the amount of the hazardous material comprises a concentration of a chemical compound.

4. The method of claim 3 , wherein the chemical compound comprises at least one of butyric acid and urea.

5. The method of claim 1 , wherein changing a setting of the autonomous vehicle comprises increasing air ventilation inside the vehicle.

6. The method of claim 1 , wherein changing a setting of the autonomous vehicle comprises opening a window of the autonomous vehicle.

7. The method of claim 1 , wherein calculating the modified route comprises adding a stop to the selected route in a vicinity of the current location of the autonomous vehicle to allow the user to exit the autonomous vehicle.

8. The method of claim 1 , wherein calculating the modified route comprises:
selecting a first-responder facility destination; and
calculating a route from the current location of the autonomous vehicle to the first-responder facility destination.

9. The method of claim 8 , wherein calculating the modified route comprises:
providing information indicative of the presence of hazardous material inside the autonomous vehicle to the first-responder facility.

10. The method of claim 1 , wherein calculating the modified route comprises:
selecting a cleaning facility destination; and
calculating a route from the current location of the autonomous vehicle to the cleaning facility destination.

11. The method of claim 10 , wherein calculating the modified route comprises:
providing information indicative of the presence of hazardous material inside the autonomous vehicle to the cleaning facility.

12. The method of claim 1 , wherein determining the amount of hazardous material inside the autonomous vehicle comprises:
receiving video input from a camera located inside the autonomous vehicle; and
determining that the video input includes an indication of hazardous material.

13. The method of claim 1 , further comprising:
displaying a biohazard warning on an outside surface of the autonomous vehicle while the autonomous vehicle travels along the modified route.

14. A system for operating an autonomous vehicle, the system comprising:
circuitry configured to:
operate the autonomous vehicle to travel along a selected route;
determine, using a sensor, an amount of hazardous material inside the autonomous vehicle during the operation of the autonomous vehicle; and
in response to determining that the amount of hazardous material exceeds a first threshold:
change a setting of the autonomous vehicle to counteract a presence of the hazardous material inside the autonomous vehicle;
calculate a modified route, wherein the modified route addresses the presence of the hazardous material inside the autonomous vehicle;
operate the autonomous vehicle to travel along the modified route;
display an override option, wherein activation of the override option cancels the setting change and causes the autonomous vehicle to travel along the selected route; and
in response to determining that the amount of the hazardous material in the autonomous vehicle subsequently exceeds a second threshold, remove the display of the override option.

15. The system of claim 14 , wherein the hazardous material is a human-generated biohazardous material, wherein a human-generated biohazardous material comprises at least one of human vomit, human blood, human stool, and human urine.

16. The system of claim 14 , wherein the sensor comprises a gas analyzer, and wherein the amount of the hazardous material comprises a concentration of a chemical compound.

17. The system of claim 16 , wherein the chemical compound comprises at least one of butyric acid and urea.

18. The system of claim 14 , wherein, while calculating the modified route, the circuitry is configured to:
add a stop to the selected route in a vicinity of the current location of the autonomous vehicle to allow the user to exit the autonomous vehicle.
