摘要： A method of controlling an automatic transmission includes determining whether a coast-down control condition is met, and performing coast-down control if the condition is met. The coast-down control includes selectively downshifting, such that engine speed is maintained above a fuel-cut threshold speed. The coast-down control condition may include a throttle opening being below a threshold opening, a shift-speed being higher than or equal to a threshold shift-speed, and a road slope being smaller than a predetermined slope. The method may also include determining whether a deceleration lock-up control condition is met, and performing deceleration lock-up control, including engaging a lock-up clutch, if the condition is met. The deceleration lock-up control condition may include a throttle opening being below a threshold opening, a shift-speed being below a threshold shift-speed, a brake not being operated, and a difference between an engine speed and a turbine speed being smaller than a reference value.

摘要： A method for controlling slip of a direct-drive clutch of a torque converter during a gear change in an automated transmission, that includes sending, as a set point, values of a cyclic opening ratio to an electro-valve for adjusting hydraulic pressure of the direct-drive clutch, wherein the initial value is determined from parameters resulting from a mapping. The value of the initial cyclic opening ratio sent as a set point is the value of the nominal initial cyclic opening ratio determined by a mapping, that is corrected by a predetermined correction coefficient memorized at the end of a previous similar gear change, from a comparison between a value of a slip representative of the slip values measured during the previous change and that of a theoretical reference slip corresponding to a nominal engine speed and turbine speed.
