Patent ID: 6909953

Claim:
A continuously-variable transmission shift control apparatus comprising: a toroidal continuously-variable transmission including a toroidal transmission unit including a power roller disposed between an input disk and an output disk, and a trunnion supporting the power roller; a shift actuating section to incline the power roller by offsetting the trunnion to achieve a shift control of the toroidal continuously-variable transmission in response to a control command; a target transmission ratio setting section to set a target transmission ratio; a transmission ratio sensing section ascertaining an actual transmission ratio of the toroidal continuously-variable transmission; a controlling section to control the actual transmission ratio toward the target transmission ratio by producing the control command in one of a forward traveling control mode for a forward vehicle traveling state, and a reverse traveling control mode for a reverse vehicle traveling state; and a control modifying section to select one of the forward traveling control mode and the reverse traveling control mode in accordance with a first parameter representing a driver's intention, to detect a change of a vehicle traveling direction in accordance with a second parameter which is the actual transmission ratio, and to modify the shift control of the toroidal continuously-variable transmission so as to shift the actual transmission ratio to a speed decreasing side upon detection of the change of the vehicle traveling direction.
