Abstract

In embodiments, an apparatus for safety collaboration in autonomous or semi-autonomous vehicles may include an input interface to obtain sensor data from one or more sensors of a computer-assisted or autonomous driving (CA/AD) vehicle, an output interface, and an analyzer coupled to the input and output interfaces to process the sensor data to identify an emergency condition of the CA/AD vehicle, and in response to the identified emergency condition, cause a communication interface of the CA/AD vehicle, via the output interface, to broadcast a request for assistance to be received by one or more nearby CA/AD vehicles. In embodiments, the apparatus may be disposed in the CA/AD vehicle.

First claim

What is claimed is:

1. An apparatus for safety collaboration in autonomous or semi-autonomous vehicles, comprising:
an input interface to obtain sensor data from one or more sensors of a computer-assisted or autonomous driving (CA/AD) vehicle;
an output interface; and
an analyzer coupled to the input and output interfaces to process the sensor data to identify an emergency condition of the CA/AD vehicle, and in response to the identified emergency condition, cause a communication interface of the CA/AD vehicle, via the output interface, to broadcast a request for assistance to be received by one or more nearby CA/AD vehicles;
wherein the input interface is further to receive one or more responses to the request for assistance provided by other nearby vehicles, and
wherein the analyzer, in response to the one or more responses, is to formulate an emergency response plan, and send the emergency response plan, via the output interface, to the other nearby vehicles that responded.

2. The apparatus of claim 1 , wherein:
the apparatus is disposed in the CA/AD vehicle, and wherein the request for assistance includes a risk assessment of the emergency condition.

3. The apparatus of claim 1 , wherein each of the one or more responses includes one or more of: size of the responding vehicle, mass of the responding vehicle, speed and location of the responding vehicle, any constraints on an ability of the responding vehicle to assist, passengers in the responding vehicle, or any special resources of the responding vehicle.

4. The apparatus of claim 1 , wherein the input interface is further to receive a confirmation signal from the one or more responding vehicles, and upon its receipt, the analyzer is further to monitor execution of the emergency response plan.

5. The apparatus of claim 4 , wherein the analyzer, upon completion of execution of the emergency response plan, is further to send a signal indicating that the emergency condition has been resolved, via the output interface, to the one or more responding vehicles.

6. The apparatus of claim 1 , wherein the apparatus comprises a distress controller having the input interface, the output interface and the analyzer.

7. The apparatus of claim 6 , further comprising:
a main vehicle controller, coupled to the distress controller and to the one or more sensors of the CA/AD vehicle;
wherein the distress controller obtains the sensor data in an alarm signal received from the main vehicle controller.

8. The apparatus of claim 7 , further comprising the one or more sensors of the CA/AD vehicle.

9. The apparatus of claim 7 , wherein at least one of:
the main vehicle controller polls the one or more sensors at one of pre-defined intervals or continuously, and generates the alarm signal in response to pre-defined sensor values, or
the distress controller is integrated into the main vehicle controller.

10. The apparatus of claim 1 , wherein the input interface obtains the sensor data at one of pre-defined intervals or continuously.

11. The apparatus of claim 1 , wherein the one or more sensors of the CA/AD vehicle include one or more of a speed sensor, a brake failure sensor, a flat tire sensor, a tire blowout sensor, a collision sensor or a steering failure sensor.

12. The apparatus of claim 1 , wherein at least one of the one or more responses from the nearby CA/AD vehicles includes at least one suggestion for remedial action to address, at least in part, the emergency condition.

13. One or more non-transitory computer-readable storage media comprising a plurality of instructions that in response to being executed cause a controller disposed in a CA/AD vehicle, to:
obtain sensor data from one or more sensors of a computer-assisted or autonomous driving (CA/AD) vehicle;
process the sensor data to identify an emergency condition of the CA/AD vehicle;
in response to the identified emergency condition, cause a communication interface of the CA/AD vehicle to broadcast a request for assistance to be received by one or more nearby CA/AD vehicles;
receive one or more responses to the distress signal from the nearby CA/AD vehicles; and
in response to the one or more responses:
formulate an emergency response plan, and
send the emergency response plan to the nearby CA/AD vehicles;

wherein the request for assistance includes at least one of an emergency type and a risk assessment.

14. The one or more non-transitory computer-readable storage media of claim 13 , wherein each of the one or more responses includes one or more of:
size of the responding vehicle, mass of the responding vehicle, speed and location of the responding vehicle, any constraints on an ability of the responding vehicle to assist, passengers in the responding vehicle, or any special resources of the responding vehicle.

15. The one or more non-transitory computer-readable storage media of claim 13 , further comprising instructions that in response to being executed cause the controller to:
receive a confirmation signal from the one or more responding vehicles, and upon receipt of the confirmation signal, monitor execution of the emergency response plan.

16. The one or more non-transitory computer-readable storage media of claim 15 , further comprising instructions that in response to being executed cause the controller to:
upon completion of execution of the emergency response plan, send to the one or more responding vehicles a signal indicating that the emergency condition has been resolved.

17. The one or more non-transitory computer-readable storage media of claim 15 , wherein the emergency type of the request for assistance includes loss of breaks, and the emergency response plan includes a jump and stop.

18. The one or more non-transitory computer-readable storage media of claim 13 , wherein the controller is at least one of:
a distress controller of a CA/AD vehicle, or
a distress controller of a CA/AD vehicle, and part of an on-board system of the CA/AD vehicle.

19. The one or more non-transitory computer-readable storage media of claim 13 , wherein the request for assistance further includes a mass, a velocity and a position of the CA/AD vehicle.

20. The one or more non-transitory computer-readable storage media of claim 13 , wherein at least one of the one or more responses from the nearby CA/AD vehicles includes at least one suggestion for remedial action to address, at least in part, the emergency condition.

21. A method of collaboratively responding to emergency conditions in computer-assisted or autonomous driving (CA/AD) vehicles, comprising:
obtaining, by an apparatus on board a CA/AD vehicle, sensor data from one or more sensors of the CA/AD vehicle;
processing, by the apparatus, the sensor data to identify an emergency condition of the CA/AD vehicle; and
in response to the identified emergency condition, causing, by the apparatus, broadcast of a request for assistance to be received by one or more nearby CA/AD vehicles;
receiving, by the apparatus, one or more responses to the request for assistance from the nearby CA/AD vehicles; and
in response to the one or more responses:
formulating by the apparatus, an emergency response plan, and
sending by the apparatus, the emergency response plan to the nearby CA/AD vehicles that responded,

wherein the request for assistance includes at least one of an emergency type and a risk assessment.

22. The method of claim 21 , wherein each of the one or more responses includes one or more of:
