Abstract: A transmission control module for a vehicle transmission includes a gear determination module, a predictive shift module, and a validation module. The gear determination module commands a first shift configuration based on an actual pedal position. The predictive shift module calculates a predicted pedal position based on the actual pedal position and commands a second shift configuration based on the predicted pedal position. The validation module validates the predicted pedal position and selectively cancels the second shift configuration based on the validation.

Abstract: A control system for determining a desired gear ratio of an automatic transmission includes a pedal rate module that determines a pedal rate of an accelerator pedal, and a shift module that determines the desired gear ratio of the transmission based on a position of the accelerator pedal and the pedal rate. The shift module determines the desired gear ratio based on a comparison of the pedal rate and a predetermined rate. The predetermined rate is based on a first period since the transmission shifted into a current gear. The shift module also determines the desired gear ratio based on one of a second period the pedal rate remains less than a positive rate and a third period the pedal rate remains greater than a negative rate. A related control method is also provided.

Abstract: A method for controlling trapped air in a clutch of an automatic clutch-to-clutch transmission includes, calculating a pulse on time based on a clutch volume and adaptive convergence. A pulse off time is calculated based on a temperature of transmission fluid. A pulse number is calculated based on the temperature of transmission fluid. A maximum pressure is commanded to the clutch based on the pulse on time and a minimum pressure is then commanded to the clutch based on the pulse off time. A pulse counter is incremented when the pulse off time expires. The steps of commanding maximum pressure, then commanding minimum pressure, and incrementing the pulse counter are repeated until the pulse counter equals a desired pulse number.
