    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： A shift control system for shifting an automatic transmission from a predetermined gear stage to another by draining an oil pressure from predetermined frictional engagement element to release the same frictional engagement element and by feeding the oil pressure to another frictional engagement element to engage the same frictional engagement element while controlling the drain oil pressure of the frictional engagement element to be released and the engaging oil pressure to the frictional engagement element to be engaged. The shift control system includes an engine racing detector for detecting the racing of the engine while the transmission is being shifted in a clutch-to-clutch manner, and a hydraulic control circuit for controlling at least one of the drain oil pressure and the engaging oil pressure, on the basis of the degree of racing of the engine, as detected by the engine racing detector, such that the amount of racing of the engine falls within a predetermined range. Since the rotational state of the engine being shifted is controlled by hydraulic control of the frictional engagement elements participating in the clutch-to-clutch shift, it is possible to reliably prevent any excessive racing of the engine and to prevent reduction of output shaft torque due to the tie-up of the frictional engagement elements.

    摘要： A control system for an automatic transmission includes a first frictional engagement element and a second frictional engagement element; and a first hydraulic servo for controlling the application/release of the first frictional engagement element and a second hydraulic servo for controlling the application/release of the second frictional engagement element. A regulator valve regulates the oil pressure to the first hydraulic servo. A signal pressure is applied to the regulator valve to establish a predetermined gear stage by switching the applied/released states of the first frictional engagement element and the second frictional engagement element by feeding/releasing oil pressure to/from the first hydraulic servo and the second hydraulic servo. The regulator valve includes a valve member having: a first pressure receiving area to which is applied the feed pressure to the first hydraulic servo as a feedback pressure in a first direction; a second pressure receiving area to which is applied the signal pressure in a second direction opposite the first direction; a fourth pressure receiving area to which is applied the feed pressure to the second hydraulic servo in the first direction, in a shift wherein the first frictional engagement element is released while the second frictional-engagement element is applied; and a third pressure receiving area to which is applied the signal pressure in the second direction, for regulation of the oil pressure only during a shift.

    摘要： A shift timing detecting system for detecting the start of a shift of an automatic transmission A in terms of a change in the R.P.M. of a predetermined rotary member after a shift command has been outputted. The shift timing detecting system comprises: a detector for detecting a change in the output R.P.M. of the automatic transmission; an arithmetic processor for arithmetically processing the change in the output R.P.M. with different coefficients to determine two processed values: a comparator for comparing the two processed values: and a shift start decider 5 for deciding the start of the shift on the basis of the result of the comparison. Since the shifting situation can be grasped from the change in the output torque accompanying the start of the shift and the change in the output R.P.M. caused by the former change, the start of the shift can be accurately detected without any time delay.
