    Abstract: A control system for an automatic transmission coupled to an engine by a torque converter includes a torque module and a first clutch control module. The torque module determines an input torque to the transmission based on an output torque of the engine. The first clutch control module adjusts an acceleration of a turbine of the torque converter during a down shift of the transmission based on the input torque. The first clutch control module adjusts the acceleration of the turbine by adjusting a first pressure of fluid supplied to an off-going clutch of the transmission based on the input torque. The first clutch control module adjusts the first pressure based on a mathematical model that relates a torque capacity of the off-going clutch, the input torque, and the acceleration. A method is also provided.

    Abstract: A control system includes a shift stage determination module and a clutch control module. The shift stage determination module determines a duration of a first power-on downshift when a second power-on downshift is requested, where a power-on downshift is a downshift of a transmission that occurs when an accelerator pedal is depressed. The clutch control module completes the first power-on downshift and selectively starts controlling the second power-on downshift before the first power-on downshift ends.

    Abstract: A vehicle includes an engine, transmission, and controller. The transmission includes a clutch pack, a clutch piston, and a position sensor. The sensor measures a changing magnetic field with respect to the piston, and encodes the measured magnetic field as a raw position signal. The controller receives the raw position signal and processes the raw position signal through a signal processing module to generate a filtered signal attenuating signal noise in the position signal. The controller determines a commanded position of the piston, and calculates separate proportional (P), derivative (D), and integral (I) control terms using the commanded position and filtered position signal. The controller also calculates a feed-forward control term using the commanded position, and a required flow rate for actuating the clutch pack as a function of the PID terms and the feed-forward commanded position term. The controller actuates the clutch pack using the commanded flow rate.
