    摘要: A dual-clutch transmission (DCT) system includes a vehicle speed offset module that generates a vehicle speed offset signal based on a preselect time and a vehicle acceleration signal. A compensated vehicle speed module generates a compensated vehicle speed based on the vehicle speed offset signal and a vehicle speed. A preselect command module generates a predicted gear signal based on a comparison between the compensated vehicle speed and a shift point from a shift pattern module. The predicted gear signal, identifies a first predicted gear of a DCT. The preselect time is defined as at least an amount of time to disengage a second predicted gear and preengage the first predicted gear.

    摘要: A dual-clutch transmission (DCT) shift sequencing system includes a shift type module that determines a shift type based on a scheduled gear and a current attained gear of a DCT. A shift sequence module determines a sequence index based on the shift type. A sequencing module generates a fork command signal and a clutch command signal based on a first sequencing table corresponding to the sequence index. A shift abort module may be included to terminate an ongoing shift and to transition to an updated shift. A fork control module controls fork shifting in the DCT based on the fork command signal. A clutch control module controls clutch engagement in the DCT based on the clutch command signal.

    摘要: A control system includes a pressure control solenoid and a flow control solenoid having an input in fluid communication with the pressure control solenoid. A piston adjusts a position of a shift fork and includes a first area in fluid communication with the pressure control solenoid and a second area in fluid communication with the flow control solenoid. A fork sensor senses a position of a shift fork. A flow determining module determines a fork velocity for the shift fork, adjusts the fork velocity to generate an adjusted fork velocity based on the position, and generates a flow command for the flow control solenoid based on the adjusted fork velocity. A pressure determining module generates a pressure command for the pressure control solenoid. The shift fork is at least one of moved from a sync position to an engaged position and from an engaged position to a neutral position.

    摘要: 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.

    摘要: 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.
