A liftgate force control assembly ( 20 ) adjusts the force required to move a liftgate ( 12 ) that is pivotally secured to a motor vehicle ( 10 ) using a hinge ( 14 ). The liftgate force control assembly includes a track ( 42 ) that is fixedly secured to the motor vehicle. A follower ( 46 ) is movably secured to the track. A strut ( 34, 36 ) has a movable end ( 26, 28 ) and a secured end ( 30, 32 ). The secured end ( 30, 32 ) is pivotally secured to the liftgate ( 12 ) and the movable end ( 26, 28 ) is pivotally secured to the follower ( 46 ). The strut ( 34, 36 ) defines a moment with respect to the hinge that secures the liftgate to the motor vehicle. A motor ( 50 ) is connected to the follower ( 46 ) to move the follower ( 46 ) along the track ( 42 ) changing the moment of the strut such that the force required to move the liftgate ( 12 ) changes as the moment changes.

1. A liftgate force control assembly for adjusting the force required to mov a liftgate pivotally secured to a motor vehicle by a hinge, said liftgate force control assembly comprising:a strut having a moving end and a secured end, said secured end being pivotally secured to one of the liftgate and

1. A liftgate force control assembly for adjusting the force required to mov a liftgate pivotally secured to a motor vehicle by a hinge, said liftgate force control assembly comprising:a strut having a moving end and a secured end, said secured end being pivotally secured to one of the liftgate and the vehicle and said moving end slidably secured to the other of the liftgate and the vehicle, said strut defining a moment with respect to the hinge;a motor operably connected to the moving end, said motor effecting reciprocating movement of said moving end changing said moment of said strut such that a force required to move the liftgate changes as said moment changes;an electronic control unit electrically connected to said motor for controlling said motor, said electronic control unit including a temperature sensor electrically connected to said electronic control unit for providing a temperature input signal of ambient temperature at said follower such that said electronic control unit changes the position of said moving and responsive to said temperature signal; anda manual switch electrically connected to said electronic control unit for providing a force level signal to said electronic control unit to manually adjust said moment of said strut wherein said force level is modified by said electronic control unit based upon said temperature input signal such that the liftgate moves based on said force level signal in a manner identical to when said manual switch was set. 2. A liftgate force control assembly as set forth in claim 1 wherein said moving end has a follower slidably engaging a track, said track having a channel for guiding said follower therealong. 3. A liftgate force control assembly as set forth in claim 2 including a drive screw extending through said track and threadably engaging said follower wherein said drive screw is driven by said motor and rotation of said drive screw drives said follower therealong. 4. A liftgate force control assembly as set forth in claim 3 wherein said moving end has a follower slidably engaging a track, said track having a channel for guiding said follower therealong. 5. A liftgate force control assembly as set forth in claim 4 including a drive screw extending through said track and threadably engaging said follower wherein said drive screw is driven by said motor and rotation of said drive screw drives said follower therealong. 6. A method adjusting a force required to move a liftgate secured to a motor vehicle by a hinge and supported by a strut connected between the motor vehicle at a connection position and the liftgate, the method comprises the steps of:receiving a signal indicating the liftgate is unlatched;receiving a signal generated by a manual switch indicative of a parameter for opening the liftgate;measuring ambient temperature;determining whether a condition for adjusting the force required to open the liftgate exists based on the signal from the manual switch and the ambient temperature; andadjusting the force required to open the liftgate by adjusting the connection position of the strut to the motor vehicle. 7. A method as set forth in claim 6 wherein the step of receiving a signal includes receiving a signal that the liftgate is ajar. 8. A method as set forth in claim 7 including the step of adjusting the connection position of the strut to the motor vehicle in a manner commensurate with the manual changes made to the switch. 9. A method as set forth in claim 8 including the step of generating a temperature signal for the measured ambient temperature. 10. A method as set forth in claim 9 wherein the step of adjusting the connection position between the strut and the motor vehicle when the temperature signal indicates a change in position is required to maintain the force required to move the liftgate constant. 11. A method as set forth in claim 10 including the step of moving the connection position beyond the position calculated using the temperature signal to prev ent continuous adjustment of the connection position due to changes in measurements of the temperature to prevent continuous movement of the strut made by the motor. 12. A vehicle havinga liftgate mounted thereon by hinges, said liftgate pivotally movable to open and clos an opening in said vehicle,a pair of struts operably connected between said liftgate and said vehicle to effect a lifting force on said liftgate, each of said struts pivotally mounted at one end to one of said liftgate and said vehicle and slidably mounted for reciprocating movement at an opposite end to the other of liftgate and said vehicle, said reciprocating movement changing a magnitude of said lifting force being transferred to said liftgate;a drive motor operably engaging said slidable end of each of said struts and operable to effect said reciprocating movement;an electronic control unit electrically connected to said motor for controlling said motor, said electronic control unit including a temperature sensor electrically connected to said electronic control unit for providing a temperature input signal of ambient temperature at said follower such that said electronic control unit changes the position of said moving and responsive to said temperature signal; anda manual switch electrically connected to said electronic control unit for providing a force level signal to said electronic control unit to manually adjust said moment of said strut wherein said force level is modified by said electronic control unit based upon said temperature input signal such that the liftgate moves based on said force level signal in a manner identical to when said manual switch was set.
