Patent ID: 8447480

Claim:
A transmission control method for a swash plate, hydraulic type continuously variable transmission having a plurality of transmission control modes comprising the following steps: wherein in a first transmission control mode, lowering an actual transmission gear ratio when a target engine speed calculated from vehicle velocity and throttle position is higher than an actual engine speed, and raising said actual transmission gear ratio when said target engine speed is lower than said actual engine speed; and in a second transmission control mode, calculating a target transmission gear ratio based on said target engine speed, which is calculated from said vehicle velocity and said throttle position, changing said actual transmission gear ratio toward said calculated target transmission gear ratio, said actual transmission gear ratio being changed by hydraulic pressure on a transmission movable member of the continuously variable transmission, and said transmission movable member is a motor swash plate or a movable member of a transmission actuator for controlling the angle of said motor swash plate.
