Method for clutch kiss point characterization

A method for operating a clutch, comprising:

• actuating the clutch between two or more positions using one or more actuators, a first position of the clutch transferring torque between two components, and a second position of the clutch separating the two components;
• based on the actuating of the clutch, determining a reference position of a first actuator at which a rate of change of positions of the first actuator in relationship to electrical currents of the first actuator is equal to a first predetermined threshold;
• based on the actuating of the clutch, determining a reference position of a second actuator at which a rate of change of positions of the second actuator in relationship to electrical currents of the second actuator is equal to a second predetermined threshold;
• and
• determining a clutch kiss point based on the reference positions of the first actuator and the second actuator.

A system comprising:

• an actuator translatable to actuate a clutch between two or more positions, the actuator engaging a clutch plate of the clutch;
• the clutch translatable between the two or more positions, a first position of the clutch transferring torque between two components, a second position of the clutch disconnecting the two components;
• a controller comprising memory and instructions configured to:
• actuate the clutch,
• based on the actuating of the clutch, determine a reference position of the actuator at which a rate of change of positions of the actuator in relationship to electrical currents of the actuator is equal to a predetermined threshold;
• and
• operate the clutch using the determined reference position as a position where force begins to be applied to the clutch.
