Patent ID: 7559872

Claim:
A controller for a continuously variable transmission capable of selecting plural drive modes, comprising: means for detecting a throttle opening; means for detecting a vehicle speed; means for detecting an engine speed; an actuator adapted to change a transmission gear ratio of the continuously variable transmission; target value output means adapted to output a target engine speed as a function of the throttle opening and the vehicle speed, the target value output means includes map means corresponding to each of the drive modes for calculating the target engine speed; and shift characteristic determination means adapted to determine a driving direction and a driving speed of the actuator based on a difference between the target engine speed and an actual engine speed, wherein the shift characteristic determination means includes shift characteristic changing means, the shift characteristic changing means being adapted to change the target engine speed on a stepwise basis from a former target engine speed calculated by former map means to a current target engine speed calculated by current map means, when the map means is changed in accordance with changing the drive mode and a difference between the former target engine speed and the current target engine speed exceeds a predetermined judgment amount.
