摘要： A controlling system of 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 upon 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 upon the set acceleration. Thus upon acceleration, the target drive force and the output rotation speed of the drive source increase.

摘要： A vehicle start control device executes a neutral control and a hill hold control, wherein, in the neutral control, a clutch provided in a power transmission path is brought into a slipping state or a released state to reduce the engine idling load and in the hill hold control, a brake force is generated to hold the vehicle against movement on a hill. A neutral release mode controller is employed to increase a torque transfer capacity of the clutch so that the clutch is engaged more gently when the neutral control is released under the hill hold control than in case of releasing the neutral control when the hill hold control is not executed. This suppresses generation of a shock that would be caused by engagement of the clutch when the neutral control is released under the hill hold control.

摘要： When the temperature of operating fluid of an actuator is low, a target input rotation speed lower limit value (NinL) is set. The lower limit value (NinL) is greater than a lower limit value set for a normal temperature of operating fluid. A target input rotation speed (Nint) is calculated from the state of running of a vehicle, such as the amount of operation of an accelerator, the vehicle speed, etc. If the target input rotation speed is lower than the lower limit value (NinL), the target input rotation speed is reset to the lower limit value (NinL). As a result of a control that includes the above-described steps, the speed ratio &ggr; becomes relatively high before the vehicle stops. Therefore, even if the speed ratio-changing rate is low, the speed ratio (&ggr;) can be brought to or near a maximum value (&ggr;max) before the vehicle stops. Thus, reductions in the speed ratio-changing rate caused by low temperature of the operating fluid of the actuator can be curbed.

摘要翻译： 当致动器的工作流体的温度低时，设定目标输入转速下限值（NinL）。 下限值（NinL）大于对工作流体的常温设定的下限值。 从车辆的行驶状态（例如加速器的运转量，车速等）算出目标输入转速（Nint）。如果目标输入转速低于下限值（NinL ），将目标输入转速重新设定为下限值（NinL）。 作为包括上述步骤的控制的结果，在车辆停止之前，速比γ变得相对较高。 因此，即使速比变化率低，在车辆停止前也可以使速比（γ）达到或接近最大值（gammamax）。 因此，可以抑制由致动器的工作流体的低温引起的速度比变化率的降低。

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 method and apparatus for controlling a continuously variable transmission of a motor vehicle includes a controller that controls the speed ratio of the continuously variable transmission in accordance with a predetermined shift condition. The method and apparatus perform shift control in a specific manner during an operation of an anti-lock brake system, for example, by smoothing at least one of the rotational speed of the input shaft and the rotational speed of the output shaft, reducing a rate of change in the speed ratio during down shifting, restricting upshifting of the CVT, increasing an amount of hydraulic oil delivered from an oil pump, and/or increasing belt clamping force.
