1. A vehicle comprising:
- a secondary charge coil; and
a park assist system including a transceiver and at least one controller programmed toduring a parking mode, output instructions to assist a driver in avoiding contact with objects within a vicinity of the vehicle, and cause the secondary charge coil to periodically generate a field to excite a remote primary charge coil, andduring a charging mode initiated based on a response to the field, output instructions to assist the driver in positioning the secondary charge coil relative to the primary charge coil.

Abstract
A park assist system may, in response to receiving a signal indicating that a remote inductive charge source is within a vicinity of a vehicle, transition from a park assist mode to a wireless charging mode. During the wireless charging mode, the park assist system generates instructions to assist a driver in positioning the vehicle relative to the inductive charge source.
