A power retractable trailer hitch for a vehicle can include a hitch assembly movably coupled to an external case or support member, and a power actuator engaging the hitch assembly. The power actuator can be operable to move the hitch assembly between a retracted position and an extended position. A controller can be operable to control activation of the power actuator. An interlock can be provided requiring a transmission of the vehicle to be in a parked position before the controller can be operable to move the hitch assembly between the retracted position and the extended position. A locking member can be operable by the controller to move between a locked position and a released position with respect to the hitch assembly. The locking member can be operable to be in a locked position, when the hitch assembly is in at least one of the extended position and the retracted position, and in a released position, when the hitch assembly is in transition between the extended position and the retracted position.

What is claimed is: 1. A retractable hitch assembly for connecting a vehicle to a trailer, comprising: a support member having a rearward edge; a hitch assembly movably coupled to the support member, the hitch assembly having a receiver with a hitch ball, the receiver configured and arranged to be selectively coupled to the trailer; a power actuator engaging the hitch assembly, the power actuator operable to move the hitch assembly between a retracted position, wherein the hitch ball is located on a first side of the rearward edge of the support member and an extended position, wherein the hitch ball is located on a second side of the rearward edge of the support member that is opposite the first side of the rearward edge of the support member; and an interlock requiring a transmission of the vehicle to be in a park position before the controller is operable to move the hitch assembly between the retracted position and the extended position. 2. The retractable hitch assembly of claim 1, wherein the hitch assembly further comprises: a carrier block assembly that is selectively attachable to the receiver of the hitch assembly, the carrier block assembly movably received within the support member. 3. The retractable hitch assembly of claim 1, wherein the power actuator further comprises: a transport mechanism operable to move the hitch assembly with respect to the support member. 4. The retractable hitch assembly of claim 1 further comprising: a mechanism operable to move a locking member between a locked position and a released position with respect to the hitch assembly. 5. The retractable hitch assembly of claim 1 further comprising: a rolling mechanism operable to slide the hitch assembly with respect to the support member. 6. The retractable hitch assembly of claim 1 further comprising: a controller operable to control the power actuator. 7. The retractable hitch assembly of claim 6 further comprising: a locking member operable by the controller to move between a locked position and a released position with respect to the hitch assembly. 8. The retractable hitch assembly of claim 1 further comprising: a user switch having at least a retracted position and an extended position, the user switch operable to control power actuator movement of the hitch assembly. 9. The retractable hitch assembly of claim 1 further comprising: an adjustable mechanical stop located adjacent at least one end of the support member operable to limit travel of the hitch assembly with respect to the support member. 10. The retractable hitch assembly of claim 1 further comprising: a locking member operable to be in a locked position when the hitch assembly is in at least one of the extended position and the retracted position. 11. The retractable hitch assembly of claim 1 further comprising: a locking member operable to be in a released position when the hitch assembly is in transition between the extended position and the retracted position. 12. The retractable hitch assembly of claim 1 further comprising: an end-of-travel sensor adjacent each end of the support member corresponding to the retracted position and the extended position of the hitch assembly, each end-of-travel sensor operable to electrically control the power actuator. 13. A retractable hitch assembly for connecting a vehicle to a trailer, comprising: a hitch assembly; a power actuator engaging the hitch assembly, the power actuator operable to move the hitch assembly between a retracted position, wherein the hitch assembly is prevented from being coupled to the trailer, and an extended position, wherein the hitch assembly is configured and arranged to be coupled to the trailer; a controller operable to control the power actuator; and an interlock requiring a transmission of the vehicle to be in a park position before the controller is operable to move the hitch assembly between the retracted position and the extended position. 14. The retractable hitch of claim 13, wherein the hitch assembly further comprises: a support member including a slot to accommodate different receiver heights of the hitch assembly. 15. The retractable hitch of claim 14, wherein the hitch assembly further comprises: a carrier block assembly that is selectively attachable to a receiver of the hitch assembly, the carrier block assembly movably received within the support member. 16. The retractable hitch of claim 15 further comprising: a rolling mechanism operable to slide the carrier block assembly with respect to the support member. 17. The retractable hitch of claim 13, wherein the power actuator further comprises: a transport mechanism operable to move the hitch assembly between the extended position and the retracted position. 18. The retractable hitch of claim 13 further comprising: a mechanism operable to move a locking member between a locked position and a released position with respect to the hitch assembly, the locking member operable to be in a locked position when the hitch assembly is in at least one of the extended position and the retracted position, and to be in a released position when the hitch assembly is in transition between the extended position and the retracted position. 19. The retractable hitch of claim 13 further comprising: an end-of-travel sensor adjacent at least one of the retracted position and the extended position of the hitch assembly, each of the at least one end-of-travel sensor operable to electrically control the power actuator. 20. A retractable hitch for a vehicle, comprising: a hitch assembly; a power actuator engaging the hitch assembly, the power actuator operable to move the hitch assembly between a retracted position and an extended position; a controller operable to control the power actuator; and an interlock requiring a transmission of the vehicle to be in a park position before the controller is operable to move the hitch assembly between the retracted position and the extended position. 21. The retractable hitch assembly of claim 13 further comprising: a locking member operable by the controller to move between a locked position and a released position with respect to the hitch assembly. 22. A method for controlling a retractable hitch for connecting a vehicle to a trailer, comprising: providing a controller operable to control a power actuator; actuating the power actuator operable to move a hitch assembly between a retracted position, wherein the hitch assembly is prevented from being coupled to the trailer, and a extended position, wherein the hitch assembly is prevented from being coupled to the trailer, in response to operation of the controller; and providing an interlock requiring a transmission of the vehicle to be in a park position before the controller is operable to move the hitch assembly between the retracted position and the extended position. 23. The method of claim 22 further comprising: actuating a mechanism operable to move a locking member between a locked position when the hitch assembly is in at least one of the extended position and the retracted position, and a released position when the hitch assembly is in transition between the extended position and the retracted position.
