Abstract

A method for controlling a mild hybrid vehicle with an electric motor is provided. The electric motor is arranged to selectively output torque and to selectively operate as a generator to harvest electrical power during operation of an internal combustion engine of the mild hybrid vehicle. An interface is provided in a location accessible outside of the vehicle. The interface is configured to control non-driving movement of the mild hybrid vehicle. An input is received from a human operator via the interface. In response to the input, the vehicle moves solely under power of the electric motor of the mild hybrid vehicle.

Claims

1. A method of controlling a mild hybrid vehicle with an electric motor arranged to selectively output torque and to selectively operate as a generator to harvest electrical power during operation of an internal combustion engine of the mild hybrid vehicle, the method comprising:

providing an interface accessible from a location outside of the vehicle and configured to control non-driving mode movement of the mild hybrid vehicle;

receiving an input from a human operator via the interface; and

in response to the input, moving the mild hybrid vehicle in the non-driving mode solely under power of the electric motor.

2. The method of claim 1, further comprising:

providing a hitch attached to the mild hybrid vehicle,

wherein moving the mild hybrid vehicle solely under power of the electric motor includes aligning a hitch coupler with the hitch.

3. The method of claim 1, further comprising steering the mild hybrid vehicle in response to the input to the interface.

4. The method of claim 1, wherein the mild hybrid vehicle further includes an ignition control, the method further comprising enabling the interface from a non-operational state in response to the removal of a key from the ignition control.

5. The method of claim 4, wherein the interface is integral with or connected to the exterior of the mild hybrid vehicle, the method further comprising placing the key in the interface prior to activating the interface.

6. The method of claim 1, wherein the interface is separate from the exterior of the mild hybrid vehicle, and prior to moving the mild hybrid vehicle solely under power of the electric motor, the method further including transmitting a wireless signal from the interface.

7. The method of claim 1, wherein moving the mild hybrid vehicle solely under power of the electric motor includes rotating a crankshaft of the internal combustion engine with the electric motor while the internal combustion engine is not operating.

8. A mild hybrid vehicle comprising:

an internal combustion engine;

an electric motor arranged to selectively output torque and to selectively operate as a generator to harvest electrical power during operation of the internal combustion engine; and

an interface located on or outside of an exterior panel of the vehicle and configured to provide a signal to control operation of the electric motor,

wherein solely the electric motor of the mild hybrid vehicle is configured to provide motive power to at least one driven wheel of the mild hybrid vehicle in response to the signal.

9. The mild hybrid vehicle of claim 8, wherein the interface is further configured to steer at least one driven wheel of the mild hybrid vehicle.

10. The mild hybrid vehicle of claim 8, wherein the interface is separate from the exterior panel of the mild hybrid vehicle and is configured to provide a wireless signal to control operation of the electric motor.

11. The mild hybrid vehicle of claim 8, wherein the electric motor is an integrated starter-generator.

12. The mild hybrid vehicle of claim 8, wherein the interface is positioned on the exterior panel of the mild hybrid vehicle at a rear side of the mild hybrid vehicle.

13. A method of controlling a mild hybrid vehicle to align a hitch of the mild hybrid vehicle with a hitch coupler, the method comprising:

operating the mild hybrid vehicle in a normal driving mode for continuous travel with access to full power from an internal combustion engine and an electric motor of the mild hybrid vehicle;

providing an interface located on or outside of an exterior panel of the mild hybrid vehicle;

enabling the interface from a non-operational state to establish a communication relationship whereby a human input to the interface is transmitted to control operation of the electric motor, wherein enabling the interface transitions operation of the mild hybrid vehicle from the normal driving mode to a non-driving mode in which the mild hybrid vehicle is limited to receiving motive power solely through the electric motor;

operating the electric motor in response to the human input to the interface to move the mild hybrid vehicle in the non-driving mode until the hitch is aligned with the hitch coupler; and

disabling the interface.

14. The method of claim 13, further comprising steering the mild hybrid vehicle in response to the human input to the interface.

15. The method of claim 13, wherein the mild hybrid vehicle further includes an ignition control, the method further comprising enabling the interface in response to removal of a key from the ignition control.

16. The method of claim 15, wherein the interface is integral with or connected to the exterior of the mild hybrid vehicle, the method further comprising placing the key in the interface prior to activating the interface.

17. The method of claim 13, wherein the interface is separate from the exterior of the mild hybrid vehicle, and prior to operating the electric motor in the non-driving mode, the method further including transmitting a wireless signal from the interface.

18. The method of claim 13, wherein operating the electric motor in the non-driving mode includes rotating a crankshaft of the internal combustion engine with the electric motor while the internal combustion engine is not operating.
