Abstract: In an automatic transmission control device of the invention configured to start an increase in engagement pressure of a start-up engagement element, when a determination threshold value for determining that a turbine rotational speed has reduced is reached or exceeded, the determination threshold value when a selection operation from a non-traveling range to a traveling range is made before a prescribed period of time from starting of an engine has elapsed, is increased and set greater than the determination threshold value when the selection operation is made after the prescribed period of time has elapsed. Accordingly, a reduction in the turbine rotational speed can be accurately determined, and thus it is possible to suppress torque fluctuations, occurring owing to engagement of a second brake, which is the start-up engagement element.

Abstract: A compact hub-embedded multi-stage transmission is provided which is implemented to achieve multi-stage shifting by using a multi-stage planetary gear set having a one stage or two or more stages and a double one-way clutch in order to impart an overrunning function during inertial travel, and at the same time, to allow rapid shifting to be made even with a small force for manipulating a shift lever by means of use of a forced shift function even in a driven travel state. Accordingly, product marketability can be maximized, and rapid shifting can be made even with a small force for manipulating a shift lever by means of use of a forced shift function even in a driven travel state, thereby considerably improving shifting accuracy.

Abstract: A transmitting torque limiting apparatus, used in a power transmitting apparatus, includes side gears (40) and side gears piece (42) one of which are axially shiftable. The side gears (40) and the side gear pieces (42) respectively have first engaging teeth (60a) and second engaging teeth (60b) each being provided with a pressure angle (Alpha). Due to such pressure angle, when an excessive torque is inputted into the power transmitting apparatus, a thrust force (F1) is generated for disengaging the engagement between the first engaging teeth (60a) and second engaging teeth (60b). Thus, inputting of the excessive torque into the power transmitting apparatus can be limited.
