An actuator assembly of an actuation system for a closure member of a vehicle is provided. The actuator assembly includes an actuator housing including a sensor housing. The actuator assembly also includes an electric motor disposed in the actuator housing and configured to rotate a driven shaft operably coupled to an extensible member that is coupled to one of a body or the closure member for opening or closing the closure member. The actuator assembly also includes an actuator controller disposed in the sensor housing of the actuator housing and coupled to electric motor and an accelerometer configured to sense movement of the closure member. The actuator controller is configured to detect the movement of the closure member using the accelerometer. The actuator controller then controls the opening or closing of the closure member based on the movement of the closure member using the electric motor.

Distributed control system for servo controlled powered door actuator

A powered actuator for moving a motor vehicle closure panel from a closed position to an open position and method of construction thereof. Powered actuator includes an electric motor configured to rotate a driven shaft and a gearbox coupled to the driven shaft. An extensible member extends through the gearbox to a proximal end on one side of the gearbox for attachment to one of a vehicle body or the closure member and to a distal end on an opposite side of the gearbox. Extensible member is configured to move between retracted and extended positions in response to rotation of the driven shaft. A contamination cover enshrouds the extensible member between the gearbox and the distal end of the extensible member. Contamination cover moves between an axially extended state and an axially retracted state while the extensible member moves between the respective retracted position and the extended position.

An electromechanical strut and method of moving a closure member of a vehicle between an open position and a closed position is provided. The electromechanical strut includes a power drive unit including a motor, a leadscrew, a planetary gearset operably connecting the motor to the leadscrew, and an electromechanical brake assembly. The electromechanical strut further includes a telescoping unit including an extensible tube and a drive nut for converting rotary motion of the leadscrew into linear motion of the telescoping unit. The electromechanical brake assembly is selectively moveable between an engaged state, wherein the leadscrew is prevented from rotating to prevent relative axial movement between the power drive unit and the telescoping unit, and a disengaged state, wherein the leadscrew is permitted to rotate to allow relative axial movement between the power drive unit and the telescoping unit.

A swing door actuation system for moving a door about a pivot axis between open closed positions relative to a vehicle body. The system includes a power swing door actuator having a housing connectable to one of the swing door and the vehicle body, an extensible member that moves relative to the housing, and connects to the other of the swing door and the vehicle body, a motor connected to a gear train, and a normally engaged clutch. The motor is operatively connected to a clutch input end through the gear train. The output end is operatively connected to the extensible member. The clutch is disengageable to disconnect the motor from the extensible member. The clutch has a slip torque that is sufficiently high to prevent movement of the door when the door is exposed to less than a selected external torque and the motor is stopped.

A friction based counterbalance mechanism for coupling with a closure panel to assist in opening and closing of the closure panel for at least a portion of a path between a fully closed position and a fully open position of the closure panel, the counterbalance mechanism including: an elongate member positioned on a longitudinal axis extending between the proximal and distal ends of the counterbalance mechanism, the elongate member having a peripheral surface, the elongate member having a proximal end for coupling to one of the closure panel and a body of a vehicle; a travel member having a body and at least one friction member mounted on the body, the travel member positioned on the longitudinal axis for reciprocation there along and for providing contact between the at least one friction member and the peripheral surface, said contact for generating a friction force in a first region along the longitudinal axis and in a second region along the longitudinal axis; and a support member coupled to the travel element at a proximal end and for coupling at a distal end to the other of the closure panel and a body of a vehicle, the support member for guiding said reciprocation. The friction based counterbalance mechanism can be incorporated as part of a biasing strut such as a spring configured strut.

In an aspect, a swing door actuation system is provided for moving a door about a vertical axis between open closed positions relative to a vehicle body. The system includes a housing connectable to one of the swing door and the vehicle body, an extensible member that moves relative to the housing, and connects to the other of the swing door and the vehicle body, a motor connected to a gear train that is non-backdrivable, and a normally engaged clutch. The motor is operatively connected to a clutch input end through the gear train. The output end is operatively connected to the extensible member. The clutch is disengageable to disconnect the motor from the extensible member. The clutch has a slip torque that is sufficiently high to prevent movement of the door when the door is exposed to less than a selected external torque and the motor is stopped.

The present invention provides a variable ratio brake pedal actuating assembly with an early increase of geometric ratio or force ratio and a subsequent decrease. The actuating assembly comprises a mount, an arm, an input portion and an input connector. The input connector is operatively connected to the arm such that the ratio varies as the arm moves. The ratio reaches a maximum peak prior to moving 30% of the fully stroked position. Also provided is an actuating assembly that uses a cam guide structure with a contoured cam surface and a link member. A configuration of the contoured cam surface, a guide slot, and the link member are such that the ratio varies as the arm is moved. Yet another aspect of the present invention is to provide a cam guided booster pin linkage assembly that provides a variable pedal ratio.
