    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 control apparatus is provided in a vehicle equipped with a power source and a continuously variable transmission. The continuously variable transmission is connected to the power source. The control apparatus includes a target power determinator, a target revolutions determinator, a determining device, a setting device and a target torque determinator. The target power determinator determines a target power of the power source. The target revolutions determinator determines target revolutions on the basis of the target power. The determining device determines whether the vehicle is a transient driving condition or not. The setting device sets the target revolutions as setting revolutions when the determining device determines that the vehicle is not in the transient driving condition. The setting device sets revolutions different from the target revolutions as the setting revolutions when the determining device determines that the vehicle is in a transient driving condition. The target torque determinator determines a target output torque of the power source on the basis of the target power and the setting revolutions. Since the vehicle is controlled in accordance with the driving condition of the vehicle, a jerky feeling can be avoided and ride quality or drivability of the vehicle is prevented from being deteriorated, even when the vehicle is in a transient driving condition.

    摘要翻译： 在配备有电源和无级变速器的车辆中设置有控制装置。 无级变速器连接到电源。 控制装置包括目标功率确定器，目标转速确定器，确定装置，设定装置和目标转矩确定器。 目标功率确定器确定电源的目标功率。 目标革命决定者根据目标力确定目标转速。 确定装置确定车辆是否是暂时驾驶状况。 当确定装置确定车辆不处于暂时驾驶状态时，设定装置将目标转数设定为设定转速。 当确定装置确定车辆处于暂时驾驶状态时，设定装置将与目标转数不同的转数设定为设定转速。 目标转矩确定器基于目标功率和设定转数来确定电源的目标输出转矩。 由于根据车辆的驾驶状况来控制车辆，所以即使在车辆处于暂时驾驶状态的情况下，也可以避免抖动的感觉，并且防止车辆的乘坐质量或驾驶性能劣化。

    摘要： A belt-driven continuously variable transmission adapted to prevent a tilting motion of a sheave under high temperature.The belt-driven continuously variable transmission is comprised of a pair of pulleys individually comprised of a fixed sheave rotated integrally with a rotary shaft and a movable sheave fitted onto the rotary shaft while being allowed to reciprocate thereon, and a driving belt applied to the pulleys to transmit power therebetween. a stopper member is disposed on an outer circumferential side and in a side where the driving belt is not contacted with the movable sheave so as to prevent the movable sheave from being tilted to widen a width between the fixed sheave and the movable sheave holding the driving belt by a load from the driving belt.
