    摘要: A transmission clutch control method includes defining a transfer function relating clutch torque to a control signal under transmission operating conditions; determining a target clutch torque for current operating conditions; determining the target control signal from the transfer function to produce target torque at the clutch; correcting clutch torque on the basis of a difference between the target clutch torque and the actual torque at the clutch by adjusting the control signal; calculating actual clutch torque with reference to transmission input torque and transmission output torque; computing a clutch torque error as a difference between calculated clutch torque and the target clutch torque; and repetitively adjusting the transfer function on the basis of the clutch torque error.

    摘要: A method of downshifting an automotive transmission. An on-coming transmission element is stroked while pressure for an off-going element is reduced. Pressure for the stroked on-coming element is increased to be sufficient to carry torque. Pressure for the off-going element is reduced below a torque transmitting amount once the stroked on-coming element has a sufficient torque carrying capacity. Torque capacities for the elements are determined from transmission output torque and acceleration and transmission input torque and acceleration. Feed forward or feedback terms for off-going and on-coming element torque capacities may be calculated using the transmission output torque, transmission input acceleration, and transmission input torque.
