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 powertrain control apparatus that controls a powertrain including a lock-up clutch, which connects an engine, in which fuel supply may be cut off, directly to an automatic transmission. The control apparatus includes an output unit, a control unit, and a setting unit. The output unit outputs an instruction to lower engagement pressure for the lock-up clutch from a value at which the lock-up clutch is engaged to a value at which the lock-up clutch is disengaged. The control unit resumes the fuel supply to the engine when a predetermined lag time has elapsed since the instruction is output. The setting unit sets the lag time so that the lag time is shorter when a temperature of a combustion chamber of the engine is a first temperature than when the temperature of the combustion chamber of the engine is a second temperature which is higher than the first temperature.

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.
