1. A clutch control system for a vehicle, comprising:
a reset module configured to selectively start a reset operation of a clutch actuator of a clutch of the vehicle, the clutch engaging and disengaging an electric propulsion motor of the vehicle to and from a gearset of the vehicle;
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 a 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.
