DETAILED DESCRIPTION

This disclosure details a winch assembly having a winch and a charge port connector. The winch can be powered by an electrified vehicle through a charge port of the electrified vehicle. This approach provides adequate power to the winch without requiring substantial modifications to a vehicle.

With reference to FIG. 1, an electrified vehicle 10 includes an electrified powertrain. In the exemplary embodiment, the electrified vehicle 10 is a battery electric vehicle (BEV). However, the concepts described herein are not limited to BEVs and could extend to other electrified vehicles, including, but not limited to, plug-in hybrid electric vehicles (PHEVs), fuel cell vehicles, etc. Therefore, although not specifically shown in this embodiment, the electrified vehicle 10 could be equipped with an internal combustion engine that can be employed either alone or in combination with other energy sources to propel the electrified vehicle 10.

In the embodiment illustrated in FIG. 1, the vehicle 10 is a full electric vehicle propelled through at least one electric machine 12 without any assistance from an internal combustion engine. The electric machine 12 may operate as an electric motor, an electric generator, or both. The electric machine 12, when powered, provides a rotational output torque to one or more drive wheels 14 through, for example, a transmission or gearbox (not shown).

A voltage bus 16 electrically connects the electric machine 12 to a battery pack 18. The traction battery pack 18 can be a high-voltage traction battery pack that includes one or more battery arrays 20 (i.e., battery assemblies or groupings of rechargeable battery cells capable of outputting electrical power to operate the electric machine and/or electrical loads of the electrified vehicle 10). The traction battery pack 18 can be recharged by connecting a charge cord to a charge port 24 of the electrified vehicle 10.

With reference now to FIGS. 2 and 3 and continued reference to FIG. 1, a winch 30 can be connected to the vehicle 10. In this example, the winch 30 is connected to the front end 34 of the vehicle 10. In another example, the winch 30 could be connected to another area of the vehicle 10, such as an aft end 36 of the vehicle 10.

The winch 30 is a powered winch. The winch 30 can include a DC motor that is used to drive the winch 30.

During operation of the winch 30, a cord 38, and a charge port connector 40 are used to electrically couple the winch 30 to the electrified vehicle 10. In particular, the charge port connector 40 couples directly to the charge port 24 of the electrified vehicle 10. Because power transfers to the winch 30 through the charge port connector 40, the winch 30 is powered through the charge port connector 40. Because the power transfers to the winch 30 through the charge port 24, the winch 30 is powered through the charge port 24.

Powering the winch 30 through the charge port connector 40 and the charge port 24 enables the winch 30 to be relatively simply transitioned from an uninstalled position, shown in FIG. 2, to an operational position, shown in FIG. 3. The winch 30 with the cord 38 and charge port connector 40 can be offered to users as an after-market item and incorporated relatively simply into the user's existing vehicle 10. If the winch 30 were instead powered entirely through the electrified vehicle 10, modifications within the vehicle 10 would potentially be required in order to power the winch 30 during operation.

Power supplied to the charge port connector 40—and ultimately to the winch 30—is from the traction battery pack 18. That is, the winch 30 is powered through the charge port connector 40 by the traction battery pack 18.

In some examples, a power source 52 that is external to the electrified vehicle 10 can provide power while the traction battery pack 18 is providing power to the winch 30. The power source 52 can be grid power, for example. In another example, the power source 52 could be another electrified vehicle. Providing power to the vehicle 10 from the external power source 52 while the traction battery pack 18 is powering the winch 30 can prevent a state of charge of the traction battery pack 18 from falling to a level inadequate for continuing to power the winch 30. The vehicle 10 can include a second charge port 54 that permits the vehicle 10 to be electrically coupled to the external power source 52 while the charge port 24 is electrically coupled to the charge port connector 40.

The vehicle 10 includes various lights, including headlights 56 at the front end 34 of the vehicle 10. As the winch 30 extends and retracts a cable 60, the headlights 56 of the vehicle 10 can be controlled to adjust in response to operation of the winch 30. For example, the headlights 56 may increase in intensity and/or brightness when power provided to the winch 30 increases due to, for example, a load on the winch 30 increasing. The lights of the vehicle 10 can provide a visual indication of a winch load rating being approached or exceeded. The lights can be used as a redundant notifier to an alert displayed within the vehicle 10 on a user's smartphone.

In FIG. 3, the winch 30 is shown in an operational position where the winch 30 is powered through the charge port connector 40 and the charge port 44 while the winch 30 is connected to the vehicle 10. In other examples, the winch 30 could be disconnected from the vehicle 10 while powered through the charge port connector 40 and the charge port 44. The winch 30 could however remain powered through the charge port 44 by keeping the charge port connector 40 coupled to the charge port 44. The winch 30 could then be used in areas where the winch 30 is spaced from the electrified vehicle 10.

It is also envisioned that the winch 30 could be designed to be regenerative so as the winch 30 lowers a load, the load power is converted into power to charge the traction battery pack 18. This can extend usage time of the traction battery pack 18.

FIG. 4 shows a digital image of another example winch 30A that is utilized at a position spaced from a vehicle (not shown). The winch 30A is powered by a vehicle through the charge port while beings used to raise and lower a load 64.

A user 68 can utilize a monitoring device, such as a smartphone 72, to monitor the movement of the load 64 utilizing the winch 30A. In some examples, the winch 30A can include a camera to take images of areas surrounding the winch 30A. These images can be sent to the smartphone 72 to help the user monitor the load 64.

In some examples, the user 68 may be able to control operation of the winch 30A from a location remote from the winch 30A. The user 68 could control operation of the winch 30A through the smartphone 72 or another device.

Controlling and monitoring the winch 30A from a location remote from the winch 30A enables the user 68 to, among other things, maintain a distance from the load 64 and the winch 30A during operation of the winch 30A.

During operation of the winch 30 of FIGS. 1-3 or the winch 30A, prognostics (e.g. HV battery range, SOC, etc.) for the electrified vehicle 10 as well as on-board sensors (e.g. sound exciters/microphones, camera/radar sensors etc.) can be relied on to alert the user 68 of issues with the winch operation (e.g. wire cable tangling, earth blockage etc.).

Sound exciters 74 (such as a microphone) can be located in the vehicle 10 near the winch 30 or 30A. These exciters would be able to listen to the pull in/out windings and detect any audible discrepancies (e.g., listen to any sound deltas from expected winch cable under tension harmonics, or listen for “grinding” noises that may indicate tangled cable/knotting etc.) Additionally, the sound exciters would be used to pick up an audible command from the user 68. The winch 30 or 30A can operate in response to a shouted command of stop, for example.

Cameras 76 of the vehicle 10 can be used to provide perspective and enable the ability to live broadcast the video feed to, for example, a site supervisor's smartphone throughout the winch control process.

In some examples, Advanced Driver Assistance System sensors or RADAR sensors can measure changing environmental conditions as well as stop the process when a destination was reached or a pile up of earth or other blockage was being created.

With reference to FIG. 5, an example method of controlling the winches 30 and 30A can begin at a step 100, which asks, at a step 104, whether a winch, such as the winches 30, 30A, is connected to the vehicle 10. If not, the method prompts the user to connect the winch at a step 108.

If the winch is connected at step 104, the method moves to a step 112, which confirms whether or not a user is present. If not, the method moves back to the step 100. If yes, the method moves from the step 112 to a step 116 where the method prompts the user to provide winch metrics such as torque required, amount of movement required, etc. In some examples, the user inputs these metrics utilizing the smart device shown in FIG. 4.

The method then moves to a step 120 which confirms whether or not the vehicle 10 is a parking gear. If not, the method moves to the step 122 which notifies the user to engage park and E-brake of the vehicle. If, at the step 120, the vehicle is shifted to park, the method moves to the step 124 where the user enters winch presets. If the presets are not entered, the method moves to the step 128, which prompts the user to enter metrics for the winch.

If at the step 124, the user has entered the winch presets, the method moves to a step 132 which estimates energy potentially used by operating the winch in the desired way. The method, in the step 132, presents the estimate to the user for review.

The method then moves to the step 136, which requests that the user acknowledge the presets. If the user has acknowledged, the method moves to the step 140 where an electrical motor of the vehicle is engaged to provide pullout control for the winch.

The method then moves to the step 144 where operation of the winch is monitored utilizing various sensors and other devices. The method then moves to a step 148 which assesses, based on the monitoring in the step 144, the potential difference between operation of the winch and desired characteristics when the winch is operating.

If the monitoring information indicates that the winch has deviated substantially from the desired operating characteristics, the method moves to the step 152 where winch operation is stopped and the user is notified. Example situations that would lead to winch potentially stopping could include a tangled or knotted cable, obstructive blockage, etc.

The method then moves from a step 152 to a step 154 where recommendations are provided to remedy the issues provided to the user in the step 152. The method then returns to the step 148.

If the monitoring information in the step 148 indicates that the winch is operating as expected, the method moves from the step 148 to a step 158, which displays updates associated with operation of the winch on a cluster or, in other examples, a smart device.

The method moves from the step 158 to the step 162, which establishes whether or not the targets set by the user in the step 162 have been achieved. If yes, the method moves to the step 166 where the user is notified that the winch targets have been reached.

The method then moves to the step 170 where the user is asked (via a prompt on a smartphone, for example) whether or not operation of the winch should continue. If yes, the method moves from a step 170 back to the step 116 where the user is again prompted of the winch metric desired. If the user does not want to operate the winch any more at the step 170, the method moves to the step 174 where the winch is retracted.

Next, at a step 178, the method confirms whether the winch has been fully retracted. If yes, the method moves to the step 182 where the user is notified that the winch is retracted. The method then moves to the step 186, which logs energy usage associated with powering the winch from the, in this example, traction battery of the vehicle. The method then moves to the step 190, which transmits these measurements to a backend database. The measurements can be used within the database to update further preset estimations.

For example, the vehicle 10 may be able to estimate based on calculated use (e.g., customer inputs) with respect to state of charge of the traction battery pack 18. The vehicle 10 can then report to the user 68 the total time of available for usage of the winch 30A. For example, a preset of 100 pounds moving up a 30-foot tall ladder going at 40-feet/minute; repeating over 1-hour yields an estimated energy usage of 6.5 kW. By extension, the vehicle 10 can provide an estimation on number of times an operation can be supported based on the vehicle prognostics (e.g. number of times to pull a car out of a ditch vs uproot a bush or small tree or life materials (lumber/masonry) before charging is needed or a second vehicle would need to be deployed.

After operation of the winch, the estimated energy usage would be compared with actual and would be updated in next preset entry. Each “preset” entry/measurements would be transmitted to a database and will be cataloged/published for aggregated profile which could be shared to other users. This can further refine the estimations.

The method then ends at the step 194.

Features of the disclosed examples include a winch that can be powered by a traction battery, an external source of power, or both. Powering the winch in this way can avoid issues associated with powering the winch from a 12-Volt accessory battery. The winch can be driven with a DC motor powered by a DC power source. DC motors can be more efficient than AC motors. The winch allows for seamless connection while benefitting from larger battery reserves through the vehicle's HV power packs.

The preceding description is exemplary rather than limiting in nature. Variations and modifications to the disclosed examples may become apparent to those skilled in the art that do not necessarily depart from the essence of this disclosure.
