A method to estimate an amount of force in a clutch pack , comprising: providing a clutch actuation system , wherein said clutch actuation system comprises a control unit , an actuation motor , a force translational device and a clutch pack ; engaging said actuation motor with said force translational device to produce a motor torque to apply a set point force to said clutch pack ; monitoring a rotational position of said actuation motor and an amount of said motor torque being applied to said clutch pack by said actuation motor at said set point force; determining a clutch clamping curve, wherein said clutch clamping curve is determined based on a relationship between said rotational position of said actuation motor and said amount of motor torque applied by said actuation motor at said rotational position of said actuator motor ; determining a clutch releasing curve, wherein said clutch releasing curve is determined based on a relationship between said rotational position of said actuation motor and said amount of motor torque applied by said actuation motor at said rotational position of said actuator motor ; modeling frictional characteristics associated with said clamping and release of said clutch pack by said control unit and wherein said model of said frictional characteristic is used to update a kiss point for said clutch pack ; estimating a clamping force and a releasing force applied by said actuation motor using said control unit ; and characterised in maintaining said amount of motor torque applied to said clutch pack between said clutch clamping curve and said clutch releasing curve at said set point force. providing a clutch actuation system , wherein said clutch actuation system comprises a control unit , an actuation motor , a force translational device and a clutch pack ; engaging said actuation motor with said force translational device to produce a motor torque to apply a set point force to said clutch pack ; monitoring a rotational position of said actuation motor and an amount of said motor torque being applied to said clutch pack by said actuation motor at said set point force; determining a clutch clamping curve, wherein said clutch clamping curve is determined based on a relationship between said rotational position of said actuation motor and said amount of motor torque applied by said actuation motor at said rotational position of said actuator motor ; determining a clutch releasing curve, wherein said clutch releasing curve is determined based on a relationship between said rotational position of said actuation motor and said amount of motor torque applied by said actuation motor at said rotational position of said actuator motor ; modeling frictional characteristics associated with said clamping and release of said clutch pack by said control unit and wherein said model of said frictional characteristic is used to update a kiss point for said clutch pack ; estimating a clamping force and a releasing force applied by said actuation motor using said control unit ; and characterised in maintaining said amount of motor torque applied to said clutch pack between said clutch clamping curve and said clutch releasing curve at said set point force. <EOS>
