摘要： A shift control apparatus outputs a command transmission ratio to a continuously variable transmission (CVT) to control a real transmission ratio of the CVT. The shift control apparatus comprises a shift mode determining section determines whether an actually selected shift mode is an automatic upshift or a power-down upshift (foot-release upshift), on the basis of the result of a previously selected shift mode, a difference between a final objective transmission ratio and a transient objective transmission ratio and a rate of change in the transmission ratio per time. The dynamic characteristic selecting section determines the dynamic characteristic according to the determined shift mode.

摘要： A speed ratio controller for a continuously variable transmission of a vehicle is provided which sets a target speed ratio according to a vehicle speed and degree of accelerator pedal depression, sets a command speed ratio according to the target speed ratio and a predetermined dynamic characteristic, and controls the transmission so as to obtain the target speed ratio while a real speed ratio follows the command speed ratio. This speed ratio controller computes a deviation between the command speed ratio and target speed ratio, and determines whether an upshift characteristic is an auto upshift, foot release upshift or foot return upshift based on the speed ratio deviation, degree of accelerator pedal depression, and variation amount of the target input shaft rotation speed. The dynamic characteristic of the command speed ratio is set according to the determination result, and the response characteristics of the transmission are thereby modified.

摘要： A speed change ratio of a continuously variable transmission for converting the rotation of the output shaft of an engine in a stepless manner and transmitting it to a drive shaft of a vehicle is controlled to a target speed change ratio. A target vehicle speed at a predetermined future time is estimated based on a real vehicle speed, and the target speed change ratio is calculated based on the estimated vehicle speed. By controlling a real speed change ratio to this target speed change ratio, the response of the transmission is enhanced. Preferably, a feedback vehicle speed is calculated by processing the estimated vehicle speed with a predetermined lag element. By integrating a difference between the real vehicle speed and feedback speed so as to estimate the vehicle speed at the predetermined future time, hunting of the speed change ratio in the speed change ratio control is suppressed.
