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 null becomes relatively high before the vehicle stops. Therefore, even if the speed ratio-changing rate is low, the speed ratio null can be brought to or near a maximum value nullmax 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。根据车辆的行驶状态，例如加速器的运转量，车速等，计算目标输入转速Nint。如果目标输入转速低于下限值NinL，则目标输入转速复位为下限值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，也可以在车辆停止前使速度比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。

A controller of the apparatus detects slippage of the power transmitting member in a predetermined period of running of the vehicle, and increases a clamping pressure that is applied to the power transmitting member when slippage of the power transmitting member is detected. The controller also stores a state of increase of the clamping pressure in a memory, and increases the clamping pressure applied to the power transmitting member in accordance with a previous state of increase of the clamping pressure that was stored in the memory in a previous period of operation of the vehicle.

摘要： A method and apparatus control an automatic transmission. A controller prohibits a down-shift of the automatic transmission when the input rotation speed of the automatic transmission is determined to be equal to or greater than a predetermined value due to operating characteristics of a device or a plurality of devices installed in a vehicle equipped with the automatic transmission and an engine. Since the down-shift of the automatic transmission is prohibited, when the input rotation speed is determined to be equal to or greater than the predetermined value, the input rotation speed of the automatic transmission is prevented from being further increased. Consequently, overrun of the engine is effectively avoided.

摘要： A vehicle drive apparatus has a pump that supplies operating fluid for performing speed shift control of a power transfer apparatus, and a driving motor that drives the pump. If it is determined that the power transfer apparatus is in a neutral state (N range), it is then determined whether the vehicle is running. If the vehicle is running, it is determined whether the operation speed of the driving motor has reached a speed that allows the pump to produce a predetermined fluid pressure. If that speed has not been reached, the motor operation speed is controlled to the speed that allows the pump to produce the predetermined fluid pressure. The vehicle drive apparatus secures a pressure and a flow of fluid when the power transfer apparatus is operated to the neutral state during the running of the vehicle.

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.
