Abstract

Particular embodiments described herein provide for a system and method to help enable a towing vehicle. In an example, the system can identify a location of the disabled vehicle, deploy the towing vehicle to the location of the disabled vehicle, where the towing vehicle uses sensor data from a sensor suite and a perception module to navigate to the location of the disabled vehicle, and use the towing vehicle to tow the disabled vehicle to a new location.

First claim

What is claimed is:

1. A method for assisting a disabled vehicle using a towing vehicle, the method comprising:
identifying a location of the disabled vehicle;
causing the towing vehicle to drive to the location of the disabled vehicle, wherein the towing vehicle uses sensor data from a sensor suite and a perception module to navigate to the location of the disabled vehicle;
establishing at least a one-way communication connection from the towing vehicle to the disabled vehicle;
performing diagnostic testing on the disabled vehicle;
determining that the disabled vehicle is disabled due to a compute issue;
determining whether a sensor interface module of the disabled vehicle is disabled and whether the towing vehicle is able to supplement sensor data of the disabled vehicle;
in response to determining that the sensor interface module of the disabled vehicle is disabled and that the towing vehicle is unable to supplement sensor data of the disabled vehicle, resetting a sensor interface module of the disabled vehicle;
in response to determining that the sensor interface module of the disabled vehicle is not disabled, determining whether the disabled vehicle is disabled due to a state issue;
in response to determining that the disabled vehicle is disabled due to the state issue, resetting a stack of the disabled vehicle and determining whether resetting the stack resolved the state issue;
in response to determining that resetting the stack resolved the state issue, virtually towing the disabled vehicle to a new location;
in response to determining that resetting the stack did not resolve the state issue, determining whether the disabled vehicle can be moved; and
in response to determining that the disabled vehicle cannot be moved, guarding the disabled vehicle using flashing lights to warn oncoming vehicles about the disabled vehicle.

2. The method of claim 1 , further comprising:
establishing a two-way communication channel between the towing vehicle and the disabled vehicle.

3. The method of claim 2 , further comprising:
in response to determining that the sensor interface module of the disabled vehicle is disabled and that the towing vehicle is able to supplement sensor data of the disabled vehicle, supplementing, by the towing vehicle, sensor data of the disabled vehicle to tow the disabled vehicle to a safe location.

4. The method of claim 1 , wherein the diagnostic testing is performed on the disabled vehicle by the towing vehicle.

5. The method of claim 1 , further comprising:
in response to determining that resetting the stack resolved the state issue, determining whether the towing vehicle can take control of the disabled vehicle.

6. The method of claim 1 , further comprising:
in response to determining that the disabled vehicle is not disabled due to the state issue, determining whether the towing vehicle can take control of the disabled vehicle.

7. The method of claim 1 , further comprising:
in response to determining that the disabled vehicle can be moved, physically towing the disabled vehicle using a physical towing mechanism involving a magnet that magnetically attaches to the disabled vehicle with enough force to physically tow the disabled vehicle.

8. A towing vehicle comprising:
a communication module;
a navigation module to control a motion of the towing vehicle and cause the towing vehicle to travel to a location of a disabled vehicle; and
a disabled vehicle diagnostic module, to:
perform diagnostic testing on the disabled vehicle; and
determine that the disabled vehicle is disabled due to a compute issue;

a disabled vehicle repair module to, based on results of the diagnostic testing:
determine whether a sensor interface module of the disabled vehicle is disabled and whether the towing vehicle is able to supplement sensor data of the disabled vehicle;
in response to determining that the sensor interface module of the disabled vehicle is disabled and that the towing vehicle is unable to supplement sensor data of the disabled vehicle, reset a sensor interface module of the disabled vehicle;
in response to determining that the sensor interface module of the disabled vehicle is not disabled, determine whether the disabled vehicle is disabled due to a state issue; and
in response to determining that the disabled vehicle is disabled due to the state issue, reset a stack of the disabled vehicle and determine whether resetting the stack resolved the state issue; and

a disabled vehicle controller, to:
in response to determining that resetting the stack resolved the state issue, take over system functions of the disabled vehicle and move the disabled vehicle;

wherein the navigation module is further to, in response to determining that resetting the stack did not resolve the state issue, control the towing vehicle to guard the disabled vehicle and to use hazard lights to warn oncoming vehicles about the disabled vehicle.

9. The towing vehicle of claim 8 , wherein the towing vehicle uses the communication module to establish a two-way communication channel with the disabled vehicle and perform the diagnostic testing on the disabled vehicle.

10. The towing vehicle of claim 8 , further comprising:
a disabled vehicle repair module, wherein based on results of the diagnostic testing, the disabled vehicle repair module repairs the disabled vehicle to allow the towing vehicle to tow the disabled vehicle.

11. The towing vehicle of claim 8 , wherein the disabled vehicle diagnostic module is further to, in response to determining that resetting the stack did not resolve the state issue, request assistance from a fleet management system.

12. The towing vehicle of claim 11 , wherein the compute issue is related to a communication module located in the disabled vehicle that is preventing the disabled vehicle from communicating with a fleet management system, wherein the towing vehicle uses the communication module in the towing vehicle as a bridge between the disabled vehicle and the fleet management system to allow the disabled vehicle to communicate with the fleet management system.

13. The towing vehicle of claim 11 , further comprising:
a sensor suite that includes a plurality of sensors, wherein the compute issue is related to collecting and/or processing of sensor data and the towing vehicle shares sensor data from the sensor suite of the towing vehicle with the disabled vehicle.

14. The towing vehicle of claim 8 , wherein
the disabled vehicle diagnostic module is further to, in response to determining that resetting the stack did not resolve the state issue, determine whether the towing vehicle can take control of the disabled vehicle.

15. The towing vehicle of claim 8 ,
wherein the disabled vehicle diagnostic module is further to, in response to determining that resetting the stack did not resolve the state issue, determine whether the disabled vehicle can be moved.

16. The towing vehicle of claim 8 , wherein the towing vehicle uses one or more visual sensors to visually inspect the disabled vehicle.

17. The towing vehicle of claim 16 , wherein a visual inspection of the disabled vehicle performed by the towing vehicle using the one or more visual sensors indicates the disabled vehicle has a flat tire and the towing vehicle activates a tire inflation mechanism to inject an expanding foam into the flat tire to temporarily fix the flat tire and allow the disabled vehicle to travel to a new location.

18. The towing vehicle of claim 8 , further comprising:
a physical towing mechanism to physically attached
