Abstract:
1. A shift controlling apparatus for a continuously variable transmission for changing a rotation of an input side rotational element driven by an engine via a power transmission element to an output side rotational element, comprising; a rapid acceleration determination unit for determining whether or not a rapid acceleration demanding condition exists according to a depressed amount of an accelerator pedal; a basic shift mode setting unit for setting a rotating speed of the input side rotational element based on a basic shift mode according to operating conditions, an accelerating shift mode setting unit for increasing the vehicle speed based on an accelerating shift mode correspondingly to an increase in an engine speed, wherein a target rotating speed of the input side rotational element corresponding to a throttle opening degree in the accelerating shift mode is larger than the target rotating speed in the basic shift mode, and is set according to the running conditions correspondingly to the increase in the engine speed, and a control unit for switching from the basic shift mode to the accelerating shift mode when the rapid acceleration determination unit determines that a rapid acceleration demanding condition is decided, wherein a transition control is implemented that the rotational speed of the input side rotational element is moderately increased, by restricting a degree of increase in the rotating speed to be lower than the degree of increase in the rotating speed in the basic shift mode, after the rotating speed of the input side rotational element is increased to a predetermined value according to the running conditions of a vehicle when switching from the basic shift mode to the accelerating shift mode.
