摘要： Construction of a continuously variable transmission device for a vehicle is achieved that, when a shift lever is shifted to a selection position for a direction opposite the traveling direction at that time, it is capable of preventing the vehicle from continuing to travel at high speed in a direction opposite the direction intended by the operator. When the shift lever is shifted to a selection position of a direction opposite the traveling direction at that time, and the vehicle speed is faster than a specified speed (V1), the connection of a clutch device that transmits power between a continuously variable transmission mechanism and a differential gear mechanism is disconnected, and the drive force from the drive source is prevented from being further transmitted to the wheels. As a result, it is possible to cause the vehicle to decelerate without accelerating even when the operator tries to move faster in the opposite direction, or when the operator steps on the accelerator pedal with the intention of accelerating in the opposite direction, and thus it is possible to prevent the vehicle from continuing to travel at high speed in the direction opposite the intended direction of the operator.

摘要： Construction is achieved that is capable of ensuring reliability of a learned value for a position of an adjustment member 24 which becomes the criterion for the transmission gear ratio control of a toroidal continuously variable transmission 4. As conditions for allowing learning of a controller 11 that controls the adjustment member 24, in which the controller 11 adjusts the transmission gear ratio of the toroidal continuously variable transmission 4 to a state in which the rotation speed of an output shaft 14 becomes “0”, learns and saves in memory the position of the adjustment member 24 in this state as the position in which the output shaft 14 is stopped while an input shaft 3 is rotated as is, the controller 11 determining whether or not the engine 1 rpm is unstable, and prohibiting execution of this learning control if the engine 1 rpm is determined as being unstable due to the engine 1 rpm fluctuating greater than the normal amount of fluctuation during idling or the like, are included.

摘要： Construction is achieved that is capable of ensuring reliability of a learned value for a step position of a stepping motor 24 which becomes the criterion for the transmission gear ratio control of a toroidal continuously variable transmission 4 without losing opportunities for learning more than necessary even when the ignition switch is turned OFF during learning of the step position. The controller 11 determines the ON/OFF state of the ignition switch 33, and when it is determined that the ignition switch 33 is in the OFF state, the controller 11 prevents learning control from being executed. The state in which the rpm of the engine 1 is dropping from after the ignition switch 33 is turned OFF is eliminated from being an object of learning control for learning the step position, such that erroneous learning is prevented, while the state in which the rpm of the engine 1 becomes stable after the ignition switch 33 is turned ON is not eliminated.
