摘要： A transmission system includes a first clutch, a second clutch, and a controller. The controller communicates with the first and second clutches and commands a gear shift. The controller calculates a torque phase time for the gear shift and determines a desired torque trajectory within said torque phase time. The controller determines on-coming torque values for the second clutch and off-going torque values for the first clutch to achieve the desired torque trajectory within the torque phase time. The controller calculates an on-coming clutch pressure based on the on-coming torque value, and an off-going clutch pressure based on the off-going torque value. The controller delays actuation of the first and second clutches to compensate for hydraulic delays.

摘要： A power transmission for a motor vehicle. The transmission includes a plurality of transmission ratio steps defined by pairs of gear carried on parallel shafts, and final output mechanisms for engaging desired transmission ratio steps. The final output mechanisms are operable for controlling the engagement of respective transmission ratio steps to minimize tractive force interruption by allowing rapid gear changes to be effected to reduce the times between shifts of gears. By sensing accelerator pedal position and vehicle speed a new transmission ratio step to be subsequently engaged can be pre-selected while an engaged gear remains engaged.

摘要： A shift control apparatus for a vehicular automatic transmission provided with a fuel cut apparatus which cuts off fuel supplied to an engine when an engine speed exceeds a predetermined value during deceleration of a vehicle, and an automatic transmission in which a gearshift is achieved with a clutch-to-clutch downshift in which a hydraulic friction device to be released is released and a hydraulic friction device to be applied is applied, further includes a controller. The controller corrects, through learning control, an apply pressure of at least one of the hydraulic friction devices to be operated for the clutch-to-clutch downshift such that an amount of drop in a rotational speed of an input shaft of the automatic transmission increases when that amount of drop is less than a predetermined value during the clutch-to-clutch downshift.

摘要： A hydraulic control system for a continuously variable transmission (CVT) includes a ratio control valve for distributing fluid to components in the CVT. The ratio control valve receives a system controlled pressure and distributes both a high pressure control fluid and a low pressure control fluid. A variable bypass valve distributes excess fluid pressure back to the inlet of a control pump. The bypass valve is responsive to the pressure differential between the high pressure control fluid and the system pressure controlled fluid to establish the operating point at which the excess fluid is bypassed. The system pressure controlled fluid is the highest pressure in the system. During operation of the CVT, the high pressure control fluid operates on one variable sheave of the CVT and the low pressure control fluid operates on another variable sheave of the CVT. The ratio control valve is responsive to a feedback control that is effective to determine the required ratio for the CVT and therefore the desired levels of the high and low pressure control fluids.
