Electric motor clutch actuator control systems and methods

Abstract

A clutch control system for a vehicle includes: a reset module configured to selectively start a reset operation of a clutch actuator of a clutch that engages and disengages an electric propulsion motor to and from a gearset; a target position module configured to perform the reset operation by setting a target position of the clutch actuator to follow a predetermined position profile for the reset operation, the reset operation including (a) opening an orifice between a hydraulic fluid reservoir and an pressure chamber of the clutch actuator (b) closing the orifice after the opening; and a clutch control module configured to actuate the clutch actuator based on the target position thereby performing the reset operation.
