摘要： A method of controlling a downshift in a transmission (10) having a main box (12) and a compounder (14) that has at least one gearset (36) and at least one friction element (38,40) separate from the main box (12) includes initiating an upshift in the compounder (14) including application of at least one friction element (e.g. a clutch) (38,40) in the compounder (14), and releasing a friction element (e.g. a clutch) (22,24,26,28,30) in the main box (12) providing a swap shift. The speed phase in the compounder (14) may trigger the speed phase in the main box (12), and vice versa. Target fluid volumes in one or both of a clutch (22,24,26,28,30) being released in the main box (12) and a clutch (38,40) being applied in the compounder (14) may be controlled and adjusted, if necessary, as a function of specific event timing in prior shifts.

摘要： A speed change control method and apparatus for a vehicular automatic transmission having a first-speed clutch for establishing a first speed and a second-speed clutch for establishing a second speed, includes subjection of at least a duty ratio Dr of a second-speed solenoid valve for supplying oil pressure to the second-speed clutch to feedback control, so that the first-speed clutch is engaged while disengaging the second-speed clutch. This thereby increases a turbine rotational speed Nt toward the first-speed synchronous rotational speed. Further, an upper limit value Dmax of the duty ratio Dr is set, and the duty ratio Dr is subject to feedback control within a resultant duty ratio range, thereby preventing the duty ratio Dr from being set at an excessive value caused by a delay in the rise of the oil pressure. As a result, even if a depression of an accelerator pedal is suddenly increased during a downshifting process, an interlock problem can be prevented, thereby ensuring smooth speed change.

摘要： A method for controlling shifting of a powershift transmission (10) of an agricultural or other off-road vehicle which uses the boost pressure developed by turbocharger of the vehicle's engine (19). This boost pressure corresponds closely to the torque produced the engine, and is monitored by a sensor (20) to generate a corresponding turbo boost pressure signal. This signal is modified in accordance with the sensed engine speed to produce a compensated turbo boost signal, which is then compared against predetermined full-load and no-load turbo boost values to determine the percentage value of full-load boost pressure, which corresponds to the present load on the engine (19). This percentage value is used to help generate appropriate duty cycle and time values for a PWM drive signal used to modulate the on-coming directional clutch into engagement at a desired rate dependent upon vehicle load.

The opening degree of the engine throttle valve is sensed and the level of the line pressure increased according to a correction schedule in the event that the throttle valve is opened beyond a predetermined amount.
