Integrated controller with sensors for electromechanical biasing member
An electromechanical biasing member for moving a closure panel between an open and a closed position relative to a motor vehicle body is provided. The electromechanical biasing member includes a housing having an inner cavity for housing an electric motor having a motor shaft and a rotary output member rotatable relative to the housing. An extension member within the housing and engageable with the rotary output member moves the closure panel between the open and closed positions in response to driving the electric motor. Also provided is a control unit positioned within the inner cavity and configured to drive the electric motor, the control unit including at least one controller board juxtaposed to the electric motor, and a plurality of control components mounted to the at least one controller board and configured to supply a drive signal to the electric motor and receive signals representative of operation of the electric motor.
