TRANSMISSION CONTROL DEVICE, TRANSMISSION CONTROL METHOD, AND PROGRAM

WIPO Patent Application WO/2023/176825

A1

[Problem] To suppress rotational vibration that induces longitudinal vibration in a vehicle, as a further measure against vibration. [Solution] This transmission control device is used for a transmission equipped with a continuously variable transmission mechanism that comprises: a primary pulley to which a drive force is inputted from a driving source mounted on a vehicle; a secondary pulley which transmits the drive force of the driving source to drive wheels; and an endless annular member which is wound around the primary pulley and the secondary pulley. This control device is equipped with a controller that performs speed change control for changing the transmission gear ratio of the continuously variable-transmission mechanism toward a high side in the case where, after rotational vibration has occurred to a rotary member of the continuously variable transmission mechanism, the rotation speed of the rotary member is being reduced by the rotational vibration.
