摘要： A maximum flow calculating unit calculates a maximum amount of hydraulic fluid that can flow into or out of an input-side hydraulic cylinder when a shift control command signal is set to a reference DUTY value, based on an estimated valve pressure difference calculated by an estimated pressure difference calculating unit, and a post-guard target sheave position setting unit performs a guard process for restricting the amount of change of the sheave position, using a guard value calculated by a guard value calculating unit based on the maximum flow amount, so as to set a post-guard target sheave position. Since the thus set target sheave position does not undergo excessive large changes nor excessively small changes during shifting, a target value for shifting is set so that a feedforward controlled variable determined based on the amount of change of the target sheave position becomes an appropriate value.

摘要： A controlling system for a vehicle with a continuously variable transmission, which can render a sufficient accelerating feeling in responsive to a driver's requirement. A controller, upon judgment of an acceleration requirement, sets a target drive force higher than the target drive force upon normal calculation upon normal operation of an accelerator pedal, and sets a target rotation speed for acceleration higher than the target rotation speed upon the normal operation and increasing with an increase of the vehicle speed by a predetermined gradient. The speed change ratio of the continuously variable transmission and the output torque of the engine are controlled such that the set target drive force is achieved, and an input shaft rotation speed of the continuously variable transmission coincides with the target rotation speed for the set acceleration. Thus, upon acceleration requirement by the driver, the target drive force increases and the output rotation speed of the drive source increases so that the sufficiently high accelerating feeling from the vehicle can be obtained.

摘要： In a shift control device for a vehicular continuously variable transmission with an arrangement in which a normal shift mode is switched to an acceleration shift mode in response to an acceleration demand, a shift control is performed to prevent deterioration to running performance due to a transition to the acceleration shift mode by increased running resistance such as ascending road running or the like against a driver will. An acceleration demand determining value PAPL is set depending on a road surface gradient Φ such that the shifting mode is more difficult to be switched to the acceleration shift mode in a larger road surface gradient Φ, than in a smaller road surface gradient Φ.

摘要： In a shift control device for a vehicular continuously variable transmission with an arrangement in which a normal shift mode is switched to an acceleration shift mode in response to an acceleration demand, a shift control is performed to prevent deterioration to running performance due to a transition to the acceleration shift mode by increased running resistance such as ascending road running or the like against a driver will.An acceleration demand determining value PAPL is set depending on a road surface gradient Φ such that the shifting mode is more difficult to be switched to the acceleration shift mode in a larger road surface gradient Φ, than in a smaller road surface gradient Φ. Such arrangement prevents the shift mode from being switched to the acceleration shift mode during ascending road running with an increase in an accelerator operation amount PAP against the driver will. During a flat road running with a small road surface gradient Φ, the shift mode is switched to the acceleration shift mode in response to the acceleration demand by the driver, thereby obtaining an excellent acceleration feeling. Meanwhile, the above arrangement prevents degradation of the ascending performance due to an inadequate drive force resulting from the shift mode switched to the acceleration shift mode during ascending road running against the driver will.
