Abstract: A method for controlling a powertrain includes the following steps: (a) determining whether a vehicle is coasting to a stop based on an accelerator pedal position; (b) determining whether an automatic transmission is in first gear; (c) shifting an input clutch from an engaged state to a disengaged state in order to operatively disconnect the automatic transmission from an internal combustion engine if the vehicle is coasting to a stop and the automatic transmission is not in first gear; and (d) shifting the automatic transmission to the first gear in order to allow the internal combustion engine to be shut down while the vehicle is coasting to a stop.

Abstract: A method of adjusting deceleration dependent shift points to maintain a target minimum turbine speed includes calculating a vehicle speed offset based on vehicle acceleration rate a predicted downshift delay for the target minimum turbine speed and converting the target minimum turbine speed to a target vehicle speed based on the deceleration condition. Thereafter, the method continues with determining a target gear based on the vehicle speed offset and the target vehicle speed, and downshifting to the target gear having vehicle speed less than or equal to a vehicle speed corresponding to the current turbine speed. The method ends with maintaining the target gear until a shift delay period is greater than a predetermined delay threshold.

Abstract: A control system is provided for shifting an automatic transmission of a motor vehicle, which includes, but is not limited to a speed controller, and an electronic control device. Through the electronic control device the parameters vehicle speed, position of the speed controller and acceleration of the speed controller can be captured. Through the electronic control device and through comparison of the captured values of the parameters with predetermined reference values a shifting time is determined for shifting the automatic transmission.
