| 摘要 | A gear change control device is provided in which a feedback control level for making an actual gear ratio between input rotational speed and output rotational speed of a transmission coincide with a target gear ratio is calculated. A control level calculation device calculates the feedback control level based on a deviation of acceleration of change in the actual gear ratio with respect to acceleration of change in the target gear ratio thereby making it possible to enhance the control responsiveness compared with a case in which the feedback control level is calculated based on the deviation of the actual gear ratio with respect to the target gear ratio, and also to detect the occurrence of a deviation of the actual value from the target value at early stage and carry out feedback, thus enabling gear change control to be carried out more linearly than in a conventional manner. | ||

| 主权项 | 1. A gear change control device comprising: a control level calculation device that calculates a feedback control level for making an actual gear ratio between input rotational speed and output rotational speed of a transmission coincide with a target gear ratio, wherein the control level calculation device calculates the feedback control level for making a deviation of acceleration of change in the actual gear ratio with respect to acceleration of change in the target gear ratio converge to zero, wherein the transmission is a toroidal type continuously variable transmission that comprises an input disk, an output disk, a pair of power rollers held between the input disk and the output disk, a pair of trunnions supporting the pair of power rollers, and a pair of hydraulic actuators connected to the pair of trunnions, and that changes gear ratio by driving the pair of trunnions by means of the pair of hydraulic actuators in directions opposite to each other and swinging the pair of power rollers around a trunnion axis so as to change the positions of points of contact with the input disk and the output disk. | ||
