    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: 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: 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.
