    摘要： Upon shifting control of differential mechanism 10, speed ratio γ0 of continuously-variable transmission portion 11 and speed ratio γ of automatic transmission portion 20 are determined by vehicle-output control device 82 on the basis of target engine output PE* and vehicle speed V, so as to establish an operating point of engine 8 which provides the target engine output PE* and which follows an optimum-fuel-economy curve, and the shifting control of the continuously-variable transmission portion 11 and the shifting control of the automatic transmission portion 20 are effected substantially concurrently, so that engine speed NE continuously changes, and the differential mechanism 10 is shifted with a reduced shifting shock. Further, the speed ratio γ0 of the continuously-variable transmission portion 11, in other words, the engine speed NE is changed by using first electric motor M1 and/or second electric motor M2, permitting an improvement in shifting response of the differential mechanism 10.

    摘要： With the automatic transmission 10-1 for vehicle according to the present embodiment, since multistage transmission of eight forward gear stages can be obtained by means of four sets of planetary gear sets 12, 16, 18 and 20, four clutches C1 through C4 and three brakes Bi through B3, the transmission can be fabricated to be light in weight and made compact, wherein the mountability thereof in a vehicle can be improved. Further, as has been made clear in FIG. 1 (b), since speed change in the respective gear stages can be carried out only by a shifting action of any two of the clutches C1 through C4 and brakes Bi through B3, the speed change control can be facilitated and it is possible to prevent a shock to the transmission from occurring.

    摘要： In a vehicular hydraulic control circuit equipped with a mechanically-operated oil pump and an electrically-operated oil pump, a hydraulic control device is provided for reducing a high load imposed on the electrically-operated oil pump, when the electrically-operated oil pump is started during stoppage of the mechanically-operated oil pump. When the electrically-operated oil pump (72) is started from a state in which both the mechanically-operated oil pump (70) and the electrically-operated oil pump (72) are stopped, the mechanically-operated oil pump (70) is pre-started, and then the electrically-operated oil pump (72) is started. Therefore, oil pressure pre-generated by the mechanically-operated oil pump (70) can reduce a load imposed on the electrically-operated oil pump (72). As a result, excessive current that may occur in a control circuit for the electrically-operated oil pump (72) can be prevented.
