Door system with door presenter control

Abstract

A door system, a presenter assembly and a method for controlling movement of a motor vehicle closure panel between a closed position, a presented position and an open position are provided. The presenter assembly includes an electric motor having a drive shaft that extends along a drive shaft axis. A clutch assembly has an engaged state when electric motor is energized and a disengaged state when electric motor is de-energized. A presenter unit has a presenter lead screw and an extensible member configured for movement between a retracted position corresponding to the closed position and an extended position corresponding to the presented position. Extensible member is biased toward the retracted position by a presenter biasing member. The presenter lead screw is rotatably driven by the output member when electric motor is energized and when clutch assembly is in the engaged state to move the extensible member against the bias of the presenter biasing member to the extended position. The extensible member is automatically biased from the extended position to the retracted position by the presenter biasing member when the electric motor is de-energized and when the clutch assembly is in the disengaged state.

Problems solved by technology

While the above opener assemblies may prove effective in moving a vehicle closure panel to the open position, such opener assemblies have some potential disadvantages

[0009] Another disadvantage of known opener assemblies relates to the high reduction gearing required in conjunction with generating sufficient force to move the vehicle closure panel to the open position, especially when ice is expected to restrict the vehicle closure panel from the fully closed position of the vehicle closure panel areas of movement in combination with the high reduction gear

Although high reduction gears are generally effective at generating the high forces required to move a vehicle closure panel to the open position, high reduction gears cannot be driven back quickly

In this way, in the event that the vehicle closure panel is suddenly and quickly moved back from the open position towards the fully closed position, such as by a user slamming the door or in windy conditions, while the opener is still in the open position or not fully returned to the opener High reduction gears and components associated with high reduction gears can be highly stressed and damaged when in the non-deployed position
