摘要： A control device for a continuously variable transmission performs transmission control so that an actual transmission control value becomes a target transmission control value. The control device includes a lead compensation unit, delay compensation unit, and a setting unit. The lead compensation unit performs lead compensation of the target transmission control value. The delay compensation unit performs delay compensation of the target transmission control value. The setting unit is configured to set as the target transmission control value a post-compensation target transmission control value for which compensation is performed by the lead compensation unit and the delay compensation unit according to at least one of an input side rotation speed of the continuously variable transmission, an input torque to a driven side rotation element of the continuously variable transmission, a transmission ratio of the continuously variable transmission, and a rate of change of the transmission ratio.

摘要： A continuously variable transmission capable of operating in a forward direction or reverse direction may be controlled in the reverse direction by providing an initial skew angle in a first skew direction, followed by a set or sequence of skew angle adjustments in an opposite direction to prevent runaway or other unintended consequences. A continuously variable transmission may include a timing plate to maintain all planets at an angle or within a range of an angle in forward and reverse operations.

摘要： A powertrain has a continuously variable transmission including a shaft rotatable about an axis. The CVT further comprises a variator assembly that includes a pulley supported on the shaft. The pulley has a movable sheave with a ramp surface. The movable sheave is axially movable on the shaft. The variator assembly also includes an endless rotatable device frictionally engaged with the movable sheave. An actuator mechanism includes a wedge component supported on the shaft. The wedge component has a wedge surface that automatically engages the ramp surface when torque on the shaft is in a first direction. The wedge surface applies a wedge force on the ramp surface. The actuator mechanism further includes an actuator that is operatively connected to the movable sheave and is activatable to apply a force on the movable sheave.

摘要： In a hydraulic control device, a hydraulic sensor is provided on an intake side of a second pump where first oil is taken in and a line pressure sensor is provided on a discharging side of the second pump where the second oil is discharged. A control unit controls driving of the second pump by controlling a motor on the basis of an output pressure detected by the output pressure sensor or a line pressure detected by the line pressure sensor.

摘要： An electronic continuously variable transmission (ECVT) system applicable to a motorcycle includes a first speed sensor, second speed sensor, continuously variable transmission (CVT) and control unit. The control unit receives a user control signal and accordingly controls a speed-changing state of the CVT. While the motorcycle is operating in a manual-operation mode, the control unit predicts, according to the user control signal, a first speed signal sent from the first speed sensor, and a second speed signal sent from the second speed sensor, whether the next gear indicated by the shift request signal will cause the motorcycle to move unsteadily. If so, the control unit ignores the shift request signal and refuses to perform gear shifting. If not, the control unit sends at least a shift control signal to the CVT so that the CVT performs gear shifting.

摘要： Disclosed is a control apparatus for a vehicular transmission comprising: a vehicle speed sensor; an accelerator opening angle sensor; and a gear-shift control section (8D) of a CVTECU 8. The vehicle speed sensor includes: an output shaft rotation speed sensor (90) configured to detect a rotation speed (rotation numbers) of an output shaft (41) of the automatic transmission; road wheel rotation speed sensors configured to detect rotation speeds (rotation numbers) of four road wheels (90B through 90E); and a vehicle speed calculating section (8B) of CVTECU 8 configured to calculate the vehicle speed from the information of the road wheel rotation speeds when a preset predetermined condition as a condition under which vertical variations of the rotation speed of the output shaft are generated is established and calculate the vehicle speed from the output shaft rotation speed information if the predetermined condition is not established.

摘要： A speed based axial force generation mechanism may generate axial force corresponding to a rotational speed of a speed based axial force generation system relative to a central axis. As the speed based axial force generation system rotates at increasing speeds, inertia causes a change in the configuration of a first rigid member and a second rigid member, resulting in a change in the axial force generated by the mechanism.
