摘要： A shift control apparatus of a continuously variable transmission for a vehicle comprises sensors for detecting operating conditions of the transmission and a motor connected to the transmission. A controller of the shift control apparatus stores different shift maps and employs one of them according to a driver's command or vehicle driving condition. The controller decides a target value of an input rotation speed of the transmission from an output rotation speed of the transmission and the load condition of a motor on the basis of the shift map and continuously changes a gear ratio of the transmission so that the transmission input rotation speed is adjusted to the target value. The controller can change the rate of the shift speed indicative of a time period of a gear ratio changing operation according to a driver's command.

摘要： In a toroidal continuously variable transmission for a vehicle, either of an automatic operation mode and a manual operation mode is selected by a driver via a selector lever (59). A speed ratio grade in the manual operation mode is also designated via the selector lever (59) by the driver. A controller (61) is programmed to control a speed ratio of the transmission to a target speed ratio corresponding to the designated speed ratio grade. The controller (61) is further programmed to prevent the speed ratio from varying after an input torque to the transmission has changed. This control may be realized by setting different target speed ratios for an identical speed ratio grade according to the input torque of the transmission.
