Abstract

A computer-implemented method includes determining a vehicle configuration indicative of a towing mode setting for the vehicle, which can include a neutral transmission gear setting, a battery conservation mode, or another towing mode setting. The method can include determining at least one vehicle operation characteristic that changes with time while the vehicle is in the towing mode setting, and performing, via a vehicle control module and based at least in part on the towing mode setting and the vehicle operation characteristic, one or more vehicle actions that include generating an alert signal indicative that vehicle damage may be imminent.

First claim

That which is claimed is:

1. A computer-implemented method, comprising:
determining a vehicle configuration indicative of a towing mode setting for a vehicle;
determining a vehicle operational characteristic that changes with time while the vehicle is in a towing mode setting; and
performing, via a vehicle control module and based on the towing mode setting and the vehicle operational characteristic, vehicle actions comprising generating an alert signal indicative that vehicle damage may be imminent;
wherein determining the vehicle operation comprises determining a vehicle speed; and wherein the vehicle actions comprise:
determining a charge status of a service battery and/or a traction battery;
starting an engine of the vehicle based on the vehicle speed and/or the charge status of the service battery and/or the traction battery;
charging, via the engine, the service battery and/or the traction battery to a predetermined charge value; and
turning off the engine responsive to determining that a charge of the service battery and/or the traction battery has reached the predetermined charge value.

2. The computer-implemented method according to claim 1 , wherein the towing mode setting comprises a neutral transmission gear setting.

3. The computer-implemented method according to claim 1 , wherein the vehicle actions comprises:
determining, based on the vehicle speed, that the vehicle is being towed at a speed that exceeds a predetermined value for sustainable towing speed; and
generating the alert signal based on determining that the vehicle is being towed at a vehicle speed that exceeds the predetermined value for sustainable towing speed associated with the vehicle.

4. The computer-implemented method according to claim 1 , wherein determining the vehicle operational characteristic comprises:
determining a voltage production of a traction motor;
comparing the voltage production to a predetermined limit for voltage; and
generating an over-voltage indication responsive to determining that the voltage production exceeds the predetermined limit for voltage.

5. The computer-implemented method according to claim 1 , wherein determining the vehicle operational characteristic comprises:
determining a transmission output speed for the vehicle.

6. The computer-implemented method according to claim 1 , wherein determining the vehicle operational characteristic comprises:
determining a wheel speed for a front wheel of the vehicle and a rear wheel of the vehicle.

7. The computer-implemented method according to claim 1 , wherein determining the vehicle operational characteristic comprises:
determining a charge status of a service battery or a traction battery.

8. The computer-implemented method according to claim 1 , wherein the vehicle actions comprise:
determining a vehicle location;
determining a jurisdictional rule based on the vehicle location; and
generating, based on the jurisdictional rule, a control command for outputting the alert signal indicative that vehicle damage may be imminent.

9. The computer-implemented method according to claim 8 , wherein the vehicle actions comprises:
executing, via control modules of the vehicle, the control command, wherein the control command causes the control module to sound an audible horn of the vehicle.

10. The computer-implemented method according to claim 1 , wherein the vehicle actions comprise:
executing, via control modules of the vehicle, the control command, wherein the control command causes the control module to flash one or more front lamps of the vehicle.

11. The computer-implemented method according to claim 10 , wherein the vehicle actions comprise:
broadcasting a command to a towing vehicle that is towing the vehicle, wherein the command is configured to cause the towing vehicle to flash a hazard signal.

12. The computer-implemented method according to claim 11 , wherein the command is configured to cause a rear camera system onboard the towing vehicle to display a view of the towed vehicle.

13. The computer-implemented method according to claim 10 , wherein the vehicle actions comprise:
generating a notification; and
broadcasting the notification to a mobile device associated with the towed vehicle.

14. The computer-implemented method according to claim 13 , wherein broadcasting the notification to the mobile device associated with the vehicle comprises:
generating the notification via a cloud-based server associated with the vehicle; and
broadcasting the notification to the mobile device from the cloud-based server.

15. The computer-implemented method according to claim 10 , wherein the vehicle actions comprise:
generating a notification; and
broadcasting the notification to a Telematic Control Unit (TCU) associated with a towing vehicle.

16. The computer-implemented method according to claim 10 , further comprising:
determining a towed distance; and
storing the towed distance to a computer memory.

17. A computer-implemented method, comprising:
determining a vehicle configuration indicative of a towing mode setting for a vehicle;
determining a vehicle operational characteristic that changes with time while the vehicle is in a towing mode setting, wherein determining the vehicle operational characteristic comprises:
determining a voltage production of a traction motor;
comparing the voltage production to a predetermined limit for voltage; and
generating an over-voltage indication responsive to determining that the voltage production exceeds the predetermined limit for voltage; and

performing, via a vehicle control module and based on the towing mode setting and the vehicle operational characteristic, vehicle actions comprising generating an alert signal indicative that vehicle damage may be imminent.

18. A computer-implemented method, comprising:
determining a vehicle configuration indicative of a towing mode setting for a vehicle;
determining a vehicle operational characteristic that changes with time while the vehicle is in a towing mode setting; and
performing, via a vehicle control module and based on the towing mode setting and the vehicle operational characteristic, vehicle actions comprising generating an alert signal indicative that vehicle damage may be imminent, wherein the vehicle actions comprise:
determining a vehicle location;
determining a jurisdictional rule based on the vehicle location; and
generating, based on the jurisdictional rule, a control command for outputting the alert signal indicative that vehicle damage may be imminent.
