Abstract

Systems and methods for situational modification of autonomous vehicle operation are disclosed. According to aspects, a computing device may detect the occurrence of an emergency event and may determine a current operation of an autonomous vehicle that may be associated with the emergency event. The computing device may determine a modification to operation of the autonomous vehicle, where the modification may represent a violation of a roadway regulation that may enable effective handling of the emergency event. The computing device may generate a set of instructions for the autonomous vehicle to execute to cause the autonomous vehicle to undertake the operation modification.

First claim

What is claimed is:

1 . A computer-implemented method in a vehicle of facilitating operation of the vehicle, the method comprising:
detecting occurrence of an emergency event at a location; and in response to detecting the occurrence of the emergency event:
determining a vehicle operation regulation specific to emergency vehicle operation,
determining, based on the location of the emergency event, a vehicle operation modification to direct the vehicle to operate in accordance with the vehicle operation regulation specific to emergency vehicle operation to enable the emergency event to be addressed,
generating, by a computer processor based on the vehicle operation modification, a set of vehicle control instructions for the vehicle, and
operating the vehicle via executing, by an on-board computing device, the set of vehicle control instructions to cause the vehicle to operate in accordance with the vehicle operation regulation specific to emergency vehicle operation to enable the emergency event to be addressed.

2 . The computer-implemented method of claim 1 , wherein detecting the occurrence of the emergency event at the location comprises:
receiving, from a data source, a notification of the emergency event at the location.

3 . The computer-implemented method of claim 1 , wherein the vehicle is an emergency vehicle and the vehicle operation regulation specific to emergency vehicle operation is a speed limit, and wherein determining the vehicle operation modification comprises:
determining the vehicle operation modification corresponding to the speed limit.

4 . The computer-implemented method of claim 3 , wherein the speed limit of the vehicle operation regulation specific to emergency vehicle operation is higher than a speed limit associated with a current location of the vehicle.

5 . The computer-implemented method of claim 1 , wherein the vehicle is an emergency vehicle and the vehicle operation regulation specific to emergency vehicle operation is a turning rule for a roadway, and wherein determining the vehicle operation modification comprises:
determining the vehicle operation modification corresponding to the turning rule for the roadway.

6 . The computer-implemented method of claim 1 , wherein the vehicle operation regulation specific to emergency vehicle operation is a direction of travel of a roadway, and wherein determining the vehicle operation modification comprises:
determining the vehicle operation modification corresponding to the direction of travel of the roadway.

7 . The computer-implemented method of claim 1 , wherein the vehicle is an autonomous vehicle.

8 . A system for facilitating operation of a vehicle, comprising:
a memory storing a set of computer-executable instructions; and a processor interfacing with the memory, and configured to execute the computer-executable instructions to cause the processor to:
detect occurrence of an emergency event at a location, and
in response to detecting the occurrence of the emergency event:
determine a vehicle operation regulation specific to emergency vehicle operation,
determine, based on the location of the emergency event, a vehicle operation modification to direct the vehicle to operate in accordance with the vehicle operation regulation specific to emergency vehicle operation to enable the emergency event to be addressed,
generate, based on the vehicle operation modification, a set of vehicle control instructions for the vehicle, and
operate the vehicle via executing the set of vehicle control instructions to cause the vehicle to operate in accordance with the vehicle operation regulation specific to emergency vehicle operation to enable the emergency event to be addressed.

9 . The system of claim 8 , further comprising:
a transceiver; wherein to detect the occurrence of the emergency event at the location, the processor is configured to:
receive, from a data source via the transceiver, a notification of the emergency event at the location.

10 . The system of claim 8 , wherein the vehicle is an emergency vehicle and the vehicle operation regulation specific to emergency vehicle operation is a speed limit, and wherein the processor determine the vehicle operation modification corresponding to the speed limit.

11 . The system of claim 10 , wherein the speed limit of the vehicle operation regulation specific to emergency vehicle operation is higher than a speed limit associated with a current location of the vehicle.

12 . The system of claim 8 , wherein the vehicle is an emergency vehicle and the vehicle operation regulation specific to emergency vehicle operation is a turning rule for a roadway, and wherein the processor determine the vehicle operation modification corresponding to the turning rule for the roadway.

13 . The system of claim 8 , wherein the vehicle operation regulation specific to emergency vehicle operation is a direction of travel of a roadway, and wherein the processor determines the vehicle operation modification corresponding to the direction of travel of the roadway.

14 . The system of claim 8 , wherein the vehicle is an autonomous vehicle.

15 . A computer-implemented method of facilitating operation of a vehicle, the method comprising:
detecting occurrence of an emergency event at a location; and in response to detecting the occurrence of the emergency event:
determining a vehicle operation regulation specific to emergency vehicle operation,
determining, based on the location of the emergency event, a vehicle operation modification to direct the vehicle to operate in accordance with the vehicle operation regulation specific to emergency vehicle operation to enable the emergency event to be addressed,
generating, by a computer processor based on the vehicle operation modification, a set of vehicle control instructions for the vehicle, and
providing the set of vehicle control instructions to an on-board computing device installed in the vehicle, wherein the on-board computing device executes the set of vehicle control instructions to cause the vehicle to operate in accordance with the vehicle operation regulation specific to emergency vehicle operation to enable the emergency event to be addressed.

16 . The computer-implemented method of claim 15 , wherein detecting the occurrence of the emergency event at the location comprises:
receiving, from a data source, a notification of the emergency event at the location.

17 . The computer-implemented method of claim 15 , wherein the vehicle is an emergency vehicle and the vehicle operation regulation specific to emergency vehicle operation is a speed limit, and wherein determining the vehicle operation modification comprises:
determining the vehicle operation modification corresponding to the speed limit.

18 . The computer-implemented method of claim 17 , wherein the speed limit of the vehicle operation regulation specific to emergency vehicle operation is higher than a speed limit associated with a current location of the vehicle.

19 . The computer-implemented method of claim 15 , wherein the vehicle is an emergency vehicle and the vehicle operation regulation specific to emergency vehicle operation is a turning rule for a roadway, and wherein determining the vehicle operation modification comprises:
determining the vehicle operation modification corresponding to the turning rule for the roadway.

20 . The computer-implemented method of claim 15 , wherein the vehicle is an autonomous vehicle.
