Patent ID: 7618341

Claim:
A transmission control device for continuously variable transmission apparatus, comprising: a continuously variable transmission comprising: a toroidal continuously variable transmission; a differential mechanism having plurality of gears; and a clutch which switches power transmitting path among the toroidal continuously variable transmission and differential mechanism; and a control unit which adjusts a speed ratio of the continuously variable transmission, wherein a rotation state of an output shaft is capable of switching between a forward rotation state and a reverse rotation state via a stopping state, while continuously rotating an input shaft in one-way direction, by changing a relative speed of the gears of the differential mechanism based on an adjustment of a transmission ratio of the toroidal continuously variable transmission, and the control unit performs: obtaining a target speed ratio of the continuously variable transmission based on a running state of a vehicle which is obtained at least a running speed of the vehicle and an throttle position, and adjusting the speed ratio to the thus obtained target speed ratio; and when the vehicle is running and a select lever is operated to a select position which runs the vehicle in a reverse direction relative to a vehicle running direction, changing the speed ratio from a value corresponding to a current running state to zero which makes the vehicle stop along with a predetermined condition, while maintaining an engagement state of the clutch.
