    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 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.
