    Abstract: A method for mitigating clunk in a driveline of a vehicle system during a declutch event includes determining a current torque request of a prime mover based on an accelerator pedal position of an accelerator pedal of the vehicle system. The method includes determining a clutch pedal position and determining, via a controller, a clutch pedal speed based on a change of the clutch pedal position over time. The method further includes modifying, via the controller, the current torque request to obtain a modified torque request based on the clutch pedal position and the clutch pedal speed such that a stored potential energy in the driveline is minimized by a time that the clutch pedal of the vehicle system is disengaged during the declutch event.

    Abstract: An active rev-matching system for a motor vehicle manual transmission includes an engine control module that monitors and adjusts an output speed of the motor vehicle's prime mover and at least one sensor that monitors movement of a shift linkage. When the at least one sensor determines the movement of the shift linkage is an in-gate downshift, the engine control module adjusts the available time for the engine control module to match the output speed of the prime mover to an input speed of the transmission.

    Abstract: A vehicle propulsion system includes a transmission having manually selectable gear ratios, a manually operable clutch for selectively connecting the transmission to an engine for receiving torque from the engine and transmitting that torque through the transmission for propelling the vehicle, a clutch position sensor that generates a clutch position signal and a controller that is programmed to receive the clutch position signal, determine an actual engine output torque, determine an actual clutch torque capacity value based upon the actual engine output torque and the clutch position signal, determine a difference between the actual clutch torque capacity value and a clutch torque capacity from a torque to position table corresponding to the clutch position signal, determine an adjusted clutch torque capacity based upon the determined difference, and control an operation of the engine based upon the adjusted clutch torque capacity.
