    摘要： The present invention has been made to eliminate a feeling of two-phase speed-change operations by causing a speed-change operation to proceed continuously when the speed-change operation is performed through two-phase control of engagement and release of four engagement elements. To accomplish this purpose, the present invention provides a control apparatus for an automatic transmission wherein a predetermined speed-change operation is achieved through a pre-phase speed-change operation in which a first engagement element and a third engagement element are released and engaged respectively and through a post-phase speed-change operation in which a second engagement element and a fourth engagement element are released and engaged respectively. The control apparatus sets a target rotational acceleration of an input shaft of the transmission, and controls release of the second engagement element for a transition to the post-phase speed-change operation in accordance with the target rotational acceleration. Thus, the input speed during the transition from the pre-phase speed-change operation to the post-phase speed-change operation changes continuously, so that bluntness is prevented from being caused between the pre-stage and post-stage speed-change operations.

    摘要： What is described is a control system (20) for controlling the coupling between a driveshaft (30) of a motor vehicle propulsion system (E) and a primary input shaft (34) of a gearbox (G) by means of a servo-assisted friction clutch (32).
    A control unit receives at its input signals indicating a command imparted by the driver of the motor vehicle by operating the accelerator pedal (P ACC ) in a driving-away or gear-changing manoeuvre, and generates - on the basis of a mathematical reference model - reference torque request signals (C MRif , C FRif ) indicating the reference torques requested from the driveshaft (30) and from the friction clutch (32), the said request signals or data varying in time in such a way as to cause synchronization between the angular velocities (ω MRif , ω PRif ) of the driveshaft (30) and of the primary gear shaft (34) to be reached at the same moment as the difference between the angular accelerations of the said shafts (30, 34) becomes zero.

    摘要： When an inertia phase has started while torque phase control is being executed, the torque phase control is ended, a target torque capacity of an engaging element in inertia phase control is corrected on the basis of a difference between the target torque capacity of the engaging element at the time when the inertia phase has started and the target torque capacity of the engaging element at the time when the torque phase control has completed (or a difference between the target torque capacity of the engaging element at the time when the inertia phase has started and the target torque capacity of the engaging element, which is set at the time when the inertia phase control has started), and the inertia phase control is started.
