摘要： PROBLEM TO BE SOLVED: To effectively prevent repetition of slip by regulating a lower limit of a clamping force when no slip is detected.
SOLUTION: The clamping force operating so as to make contact a transmission member for transmitting torque between an input member and an output member with the input member and the output member is increased when a relative slip between the input member or the output member and the transmission member. The controller of a continuously variable transmission decreases the clamping force when the slip is not detected over a predetermined period. The controller has a clamping-force decrease limiting means (steps S9 and S10) for setting the lower limit of the decreased clamping force at a pressure higher than the clamping force at the slip detection time.

摘要： PROBLEM TO BE SOLVED: To quickly reduce internally enclosed pressure in a variable transmission mechanism without generating a slip in the variable transmission mechanism. SOLUTION: The internally enclosed pressure control device reduces the internally enclosed pressure for the variable transmission mechanism from designated pressure to pressure lower than the designated pressure within a range having no slip. A load for a power source of a vehicle mounting the variable transmission mechanism or a physical value varied in proportion to the load for any rotary member for forming a driving system including the variable transmission mechanism are controlled within a designated range. The internally enclosed pressure control device comprises the steps (Steps S1 and S2) of: permitting the internally enclosed pressure for reducing toward the lower pressure if a permission condition, in which rotary acceleration of any rotary member for forming the driving system is within a predetermined range, is effected; and prohibiting the internally enclosed pressure for reducing toward the lower pressure if the permission condition is not effected.

摘要： PROBLEM TO BE SOLVED: To correctly determine the ratio of the thrust in each pulley clasping a belt without causing slipping of the belt.
SOLUTION: In a pulley thrust control device, the belt is wound around a drive pulley and a driven pulley, and the thrust of the drive pulley for clasping the belt or the thrust of the driven pulley for clasping the belt can be controlled. The pulley thrust control device comprises a motion state determining means (Steps S7-S11), a thrust reducing means (Step S13), and a thrust ratio determining means (Step S14). The motion state determining means determines the situation in which the torque or the transmission gear ratio acting on the belt- type non-stage transmission hardly varies. The thrust reducing means reduces the thrust when the motion state determining means determine the situation in which the torque or the transmission gear ratio hardly varies. The thrust ratio determining means determines the value of the ratio of the thrust of the drive pulley to that of the driven pulley by reducing the thrust.
