Abstract: A system includes a torque converter having a turbine, a transmission having friction clutches and an input member connected to the turbine, and a controller. The controller is programmed to control a change-of-mind shift maneuver of the transmission. By executing a method, the controller detects the change-of-mind shift maneuver, predicts an acceleration profile of the turbine for a next-requested shift of the detected shift maneuver as a function of a calibrated desired shift time and an output speed of the transmission, calculates a shift control value for a next-requested shift of the shift maneuver using the predicted acceleration profile, and executes the next-requested shift via the clutches using the calculated shift control value. The shift maneuver may be a skip-at-sync quick shift-to-quick shift or power downshift-to-power downshift. The shift value may be a clutch pressure for an offgoing holding clutch or a torque management level from an engine.

Abstract: Methods and systems are provided for controlling an automated exit of a vehicle from a parking spot that include sensors configured to obtain sensor data pertaining to the parking spot and lanes of a roadway in proximity to the parking spot, including a respective direction of flow of traffic; and processors coupled to the sensors and configured to at least facilitate selecting a lane for the vehicle to enter upon exiting the parking spot, based at least in part on the direction of flow of traffic; selecting a turn for the vehicle to make such that the vehicle is travelling in the same direction as the direction of flow of traffic; and executing the automated exit of the vehicle from the parking spot into the selected lane by making the selected turn of the vehicle into the selected lane.

Abstract: A method of controlling a transmission includes determining if the transmission is currently executing a first torque controlled shift from a first gear ratio to a second gear ratio. A torque controlled shift is defined as a shift control operation in which the speed of the engine is controlled to perform a shift operation. When a second torque controlled shift is detected while the transmission is currently executing the first torque controlled shift, a dual torque controlled shift strategy is executed, which merges a first shift control strategy for executing the first torque controlled shift with a second shift control strategy for executing the second torque controlled shift. The dual torque controlled shift strategy seamlessly executes the first torque controlled shift and the second torque controlled shift without a time delay and engine torque disruption therebetween.
