摘要： A shift control system for a continuously variable transmission, in which a road load on a vehicle is detected, the lower limit speed is set according to the detected road load, in which a target input speed, as set according to the running state of a vehicle, is restricted with the set lower limit speed, and in which the gear ratio of the continuously variable transmission is controlled so that the actual input speed may be equal to the target input speed restricted. The target input speed is restricted after the actual input speed is more than the lower limit value, when the road load is light, and said target input speed is restricted irrespective of the actual input speed when the road load is heavy.

摘要： An apparatus and a method control a belt-type continuously variable transmission of a vehicle having a continuously variable speed ratio, which is a ratio of a rotation speed of an input shaft to a rotation speed of an output shaft. The speed ratio of the transmission is controlled by changing a groove width of each of the pulleys, and a belt clamping pressure applied to at least one of the pulleys to clamp the torque transfer belt also is controlled. Furthermore, the speed ratio of the transmission is set to a low-load speed ratio when it is determined that control of the belt clamping pressure has failed and the belt clamping pressure is raised to a high level. The low-load speed ratio is predetermined so that a load applied to the torque transfer belt is substantially minimized.

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.
