A method is disclosed for managing charging of an electrical storage unit of a motor vehicle at a wireless vehicle charging station. The method includes: receiving a sensor signal indicating detection of an obstruction within a predetermined proximity of the vehicle charging station; determining whether the detected obstruction is living or lifeless; initiating, via a vehicle controller responsive to the detected obstruction being a living object, a first remedial action strategy that commands the vehicle to generate a visual or audible cue to drive away the living object; and, initiating, via the vehicle controller responsive to the detected obstruction being a lifeless object, a second remedial action strategy that commands the motor vehicle to move and thereby avoid contact with the object. ## Claims ### Claim 1 A method for managing charging of an electrical storage unit of a motor vehicle at a wireless vehicle charging station, the method comprising: communicating, via a vehicle controller with the wireless vehicle charging station, to initiate charging of the electrical storage unit of the motor vehicle;

determining, via the vehicle controller, whether the detected obstruction is a living object or a lifeless object; initiating, via the vehicle controller responsive to a determination that the detected obstruction is a living object, a first remedial action strategy including commanding the motor vehicle to generate a visual or audible cue configured to drive away the living object; and initiating, via the vehicle controller responsive to a determination that the detected obstruction is a lifeless object, a second remedial action strategy including directing the motor vehicle to reposition such that the motor vehicle avoids contact with the lifeless object. ### Claim 2 (depends on 1) The method of claim 1, wherein the motor vehicle includes a sound-generating component, and wherein the first remedial action strategy includes commanding the sound-generating component to output the audible cue configured to drive away the living object. ### Claim 3 (depends on 1) The method of claim 1, wherein the motor vehicle includes a light-generating component, and wherein the first remedial action strategy includes commanding the light-generating component to output the visual cue configured to drive away the living object. ### Claim 4 (depends on 1) The method of claim 1, wherein the motor vehicle has autonomous driving capabilities, and wherein the first remedial action strategy includes autonomously rerouting the motor vehicle to evade the living object. ### Claim 5 (depends on 1) The method of claim 1, wherein the motor vehicle has autonomous driving capabilities, and wherein the second remedial action strategy includes autonomously repositioning the motor vehicle to a new location or a new position. ### Claim 6 (depends on 1) The method of claim 1, wherein the motor vehicle includes a light-generating component and a sound-generating component, wherein the lifeless object is a second motor vehicle, and wherein the second remedial action strategy includes commanding the light-generating component to output a visual prompt and/or commanding the sound-generating component to output an audible prompt, both configured to prompt the second motor vehicle to move. ### Claim 7 (depends on 1) The method of claim 1, further comprising: receiving, via the vehicle controller, a signal indicating that charging of the electrical storage unit has commenced; and continuously monitoring the predetermined proximity of the wireless vehicle charging station for the obstruction during charging of the electrical storage unit. ### Claim 8 (depends on 1) The method of claim 1, further comprising, upon completion of the first or second remedial action strategy, initiating a retry strategy, the retry strategy including a repeated loop of: communicating, via the vehicle controller with the sensor, to determine if the obstruction is still within the predetermined proximity of the wireless vehicle charging station; responsive to a determination that the obstruction is still within the predetermined proximity, re-executing a corresponding one of the initiating operations; and responsive to a determination that the obstruction is not within the predetermined proximity, concluding the retry strategy. ### Claim 9 (depends on 8) The method of claim 8, wherein the retry strategy further includes: determining, prior to the re-executing of the corresponding initiating operation, if a predetermined time period has expired or a maximum number of cycles of the repeated loop has been completed; and responsive to a determination that the predetermined time period has expired or the maximum number of cycles have been completed, concluding the retry strategy. ### Claim 10 (depends on 1) The method of claim 1, further comprising transmitting, via the vehicle controller to a user, a user prompt with an indication of the detected obstruction and a request for approval to initiate the first or the second remedial action strategy. ### Claim 11 (depends on 1) The method of claim 1, further comprising receiving, via the vehicle controller from a user input device of a user, one or more user parameters modifying the first remedial action strategy or the second remedial action strategy, or both. ### Claim 12 (depends on 1) The method of claim 1, further comprising: receiving, via the vehicle controller, an indication that charging of the electrical storage unit has commenced;
