Abstract

Methods and systems for reducing vehicle and animal collisions. One system includes an electronic processor configured to receive vehicle data. The electronic processor is also configured to determine a collision risk of the vehicle based on the vehicle data, the collision risk representing a probability of a collision between the vehicle and an animal. The electronic processor is also configured to adjust a collision parameter of the vehicle based on the collision risk. The electronic processor is also configured to identify when an animal is in a path of the vehicle based on the vehicle data. The electronic processor is also configured to, when an animal is identified in the path of the vehicle, automatically perform a vehicle operation based on the adjusted collision parameter.

First claim

What is claimed is:

1. A system for reducing vehicle and animal collisions, the system comprising:
an electronic processor configured to
receive vehicle data including at least one selected from a group consisting of a time of day, a time of year, and an identified road sign, wherein the vehicle data is collected prior to an animal being within a path of a vehicle,
determine a current collision risk of the vehicle based on the vehicle data, the current collision risk representing a probability of a future collision between the vehicle and an animal,
adjust a collision parameter of the vehicle based on the current collision risk,
after adjusting the collision parameter of the vehicle,
identify an animal in the path of the vehicle based on the vehicle data, and
in response to identifying the animal in the path of the vehicle, automatically perform a vehicle operation based on the adjusted collision parameter.

2. The system of claim 1 , wherein the electronic processor is further configured to
determine a risk of an area that the vehicle is traveling through based on the vehicle data, and
determine the current collision risk of the vehicle based on the risk of the area that the vehicle is traveling through.

3. The system of claim 1 , wherein the electronic processor is further configured to
compare the current collision risk with a predetermined collision risk threshold, and
adjust the collision parameter of the vehicle when the current collision risk exceeds the predetermined collision risk threshold.

4. The system of claim 1 , wherein the vehicle operation includes at least one selected from a group consisting of flashing headlights of the vehicle and outputting an ultrasonic frequency.

5. The system of claim 1 , wherein the electronic processor is configured to adjust the collision parameter of the vehicle by prefilling brakes of the vehicle.

6. The system of claim 1 , wherein the vehicle operation includes adjusting a suspension of the vehicle to increase a pitch of the vehicle prior to the vehicle colliding with the animal.

7. The system of claim 1 , wherein the electronic processor is configured to adjust the collision parameter by limiting a target deceleration of the vehicle.

8. The system of claim 1 , wherein the electronic processor is configured to adjust the collision parameter by modifying an activation threshold of a safety system of the vehicle.

9. The system of claim 1 , wherein the electronic processor is configured to adjust the collision parameter by adjusting a collision response procedure of a safety system of the vehicle, wherein the collision response procedure controls where to autonomously steer the vehicle.

10. A method for reducing vehicle and animal collisions, the method comprising:
receiving, with an electronic processor, a first set of vehicle data, wherein the first set of vehicle data is collected before an animal is in a path of a vehicle;
determining, with the electronic processor, a current collision risk of the vehicle based on the first set of vehicle data, the current collision risk representing a probability of a future collision between the vehicle and an animal;
adjusting, with the electronic processor, a collision parameter of the vehicle based on the current collision risk;
after adjusting the collision parameter of the vehicle,
receiving, with the electronic processor, a second set of vehicle data, the second set of vehicle data collected after adjusting the collision parameter of the vehicle;
identifying, with the electronic processor, that an animal is in the path of the vehicle based on the second set of vehicle data; and
in response to identifying the animal in the path of the vehicle, automatically performing, with the electronic processor, a vehicle operation based on the adjusted collision parameter.

11. The method of claim 10 , further comprising:
identifying a road sign based on the vehicle data; and
determining the current collision risk of the vehicle based on the road sign.

12. The method of claim 11 , wherein determining the current collision risk of the vehicle includes determining the current collision risk of the vehicle based on a collision risk associated with an area that the vehicle is currently traveling through.

13. The method of claim 10 , further comprising:
comparing the current collision risk with a predetermined collision risk threshold; and
adjusting the collision parameter of the vehicle when the current collision risk exceeds the predetermined collision risk threshold.

14. The method of claim 10 , wherein automatically performing the vehicle operation includes performing a brake jerk, wherein the brake jerk notifies a driver of the vehicle of a potential collision with the animal.

15. The method of claim 10 , wherein adjusting the collision parameter of the vehicle includes prefilling brakes of the vehicle.

16. The method of claim 10 , wherein adjusting the collision parameter of the vehicle includes limiting a target deceleration of the vehicle.

17. The method of claim 10 , wherein adjusting the collision parameter of the vehicle includes reprioritizing a collision response procedure of a safety system of the vehicle to prioritize minimizing injury to one or more occupants of the vehicle over minimizing injury to the animal.

18. The method of claim 10 , further comprising:
determining a breed classification of the animal; and
automatically performing the vehicle operation based on the breed classification of the animal.

19. The method of claim 10 , further comprising:
before receiving the second set of vehicle data,
receiving a third set of vehicle data,
determining an updated collision risk based on the third set of vehicle data, and
re-adjusting the collision parameter of the vehicle based on the updated collision risk,

wherein the vehicle operation is performed based on the re-adjusted collision parameter of the vehicle.
