Abstract

Systems of an electrical vehicle and the operations thereof are provided. In particular, a towing cable and methods for utilizing the same in a towing scenario are described. The towing cable is described to facilitate the transfer of power between vehicles as well as data between vehicles. The data transferred between the vehicles involved in the towing include sensor information of the towed vehicle as well as control signals.

First claim

What is claimed is:

1 . A vehicle, comprising:
a charging port that facilitates connection with a towing cable; a power source that is configured to receive power from the charging port or provide power to the charging port when the towing cable is connected with the charging port; and a controller in electrical communication with the charging port, wherein the controller is configured to receive and/or provide data to the charging port to facilitate vehicle-to-vehicle communications via the towing cable.

2 . The vehicle of claim 1 , wherein the controller provides data to the charging port in the form of control signaling when the power source is providing power to the charging port.

3 . The vehicle of claim 2 , wherein the control signaling is communicated to a towed vehicle via the towing cable and wherein the control signaling causes the towed vehicle to adjust at least one of a direction of travel, speed, acceleration, or deceleration in response to the control signaling.

4 . The vehicle of claim 1 , wherein the controller provides data to the charging port in the form of sensor information when the power source is receiving power from the charging port.

5 . The vehicle of claim 4 , wherein the sensor information is communicated to a towing vehicle via the towing cable and wherein the sensor information corresponds to information obtained from one or more sensors of the vehicle and is used by the towing vehicle in connection with making control decisions for the vehicle.

6 . The vehicle of claim 5 , wherein the towing cable does not transfer substantial mechanical forces from the towing vehicle to the vehicle.

7 . The vehicle of claim 1 , wherein the data is communicated via the towing cable via one or more digital signals.

8 . The vehicle of claim 1 , wherein the power is provided as at least one of three-phase AC power, single-phase AC power, and DC power.

9 . The vehicle of claim 8 , wherein the data includes both control signaling and sensor information and wherein the power, control signaling, and sensor information are each communicated over different conductors of the towing cable.

10 . A towing vehicle configured to tow a towed vehicle, the towing vehicle comprising:
a charging port that facilitates connection with a towing cable; a power source that is configured to provide power to the charging port when the towing cable is connected with the charging port and when the towing cable is also connected with the towed vehicle; and a controller in electrical communication with the charging port, wherein the controller is configured to receive and/or provide data to the charging port to facilitate vehicle-to-vehicle communications via the towing cable.

11 . The towing vehicle of claim 10 , wherein the controller provides data to the towed vehicle in the form of control signaling and wherein the controller receives data from the towed vehicle in the form of sensor information.

12 . The towing vehicle of claim 11 , wherein the charging port comprises separate interfaces for communicating the power, control signaling, and sensor information.

13 . The towing vehicle of claim 11 , wherein the controller is configured to operate in a towing mode while the towing cable is connected to both the towing vehicle and towed vehicle and wherein the towing mode causes the controller to consider the sensor information received from the towed vehicle in connection with producing the control signaling for the towed vehicle as well as producing control signaling for the towing vehicle.

14 . The towing vehicle of claim 10 , wherein the charging port comprises one or more indicators that identify when both power and data are being exchanged via the towing cable.

15 . A towed vehicle configured to be towed by a towing vehicle, the towed vehicle comprising:
a charging port that facilitates connection with a towing cable; a power source that is configured to receive power from the charging port when the towing cable is connected with the charging port and when the towing cable is also connected with the towing vehicle; and a controller in electrical communication with the charging port, wherein the controller is configured to receive and/or provide data to the charging port to facilitate vehicle-to-vehicle communications via the towing cable.

16 . The towed vehicle of claim 15 , wherein the controller provides data to the towing vehicle in the form of sensor information obtained from one or more sensors of the towed vehicle and wherein the controller receives data from the towed vehicle in the form of control signaling.

17 . The towed vehicle of claim 16 , wherein the charging port comprises separate interfaces for communicating the power, control signaling, and sensor information.

18 . The towed vehicle of claim 16 , wherein the controller is configured to operate in a limp-home mode while the towing cable is connected to both the towing vehicle and towed vehicle and wherein the limp-home mode causes the controller to adjust one or more actuators of the towing vehicle in accordance with the control signaling received from the towing vehicle.

19 . The towed vehicle of claim 15 , wherein the charging port comprises one or more indicators that identify when both power and data are being exchanged via the towing cable.

20 . The towed vehicle of claim 15 , wherein the power is provided as at least one of three-phase AC power, single-phase AC power, and DC power.
