    Abstract: A vehicle includes torque sources, a transmission, and a controller programmed to execute a method. In executing the associated method, the controller determines whether continuous output torque is required through a torque exchange. When continuous output torque is required, the controller synchronizes and fills the oncoming clutch, estimates capacity of the oncoming clutch, and expands a short-term torque capacity of the oncoming clutch during the torque exchange, doing so in response to a control objective having a threshold priority. Onset of the torque exchange delays until the short-term torque capacity is sufficient for receiving all torque load from the offgoing clutch without affecting output torque. The controller asynchronously controls the offgoing clutch and synchronously controls the oncoming clutch through the torque exchange, and loads the synchronous oncoming clutch via an expanding set of long-control torque capacity limits as a function of a simultaneously exhausting of the offgoing clutch load.

    Abstract: A vehicle includes a transmission, an electrically-driven fluid pump which supplies pressure to a hydraulically-actuated clutch of the transmission, and pump motor sensors positioned with respect to a pump motor of the fluid pump. The sensors are configured to measure electrical properties of the pump motor, and to output the measured electrical properties as input signals. A controller detects when the hydraulic circuit is fully charged by determining an actual speed of the pump motor. The controller calculates an average pump torque and a slope of the average pump torque for the pump motor using the input signals. A flag is set via the controller indicating that a calibrated line pressure has been attained in the hydraulic circuit when the slope of the average pump torque reaches zero and the speed of the pump motor reaches a calibrated speed.

    Abstract: A method to monitor a torque transfer device configured to transfer torque within an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and at least one electric machine includes executing a failure detection strategy in response to a detected slip condition of the torque transfer device. The failure detection strategy includes monitoring a magnitude of energy loss of the torque transfer device. A failure condition in the torque transfer device is detected when the magnitude of energy loss achieves a predetermined energy threshold.
