摘要： A control apparatus for an automatic transmission mechanism including a continuously variable transmission having a drive pulley, a driven pulley, and a belt extending around the two pulleys. When beginning of the start of a drive source for driving a vehicle has been detected, a first command oil pressure as a command value of a first control oil pressure supplied to a cylinder chamber of the drive pulley is set to a first predetermined oil pressure substantially equal to 0, and a second command oil pressure as a command value of a second control pressure supplied to a cylinder chamber of the driven pulley is set to a second predetermined oil pressure higher than the first predetermined oil pressure. When the detected second control oil pressure has reached a predetermined threshold value, it is determined that filling of the cylinder chamber of the driven pulley has been completed. A control for increasing the first command oil pressure is performed from a time point when completion of the filling of the cylinder chamber of the driven pulley has been determined.

摘要： A hydraulic pressure supply apparatus, capable of quickly supplying hydraulic pressure to a power transmission apparatus and extending the service life of an accumulator for supplying hydraulic pressure to the power transmission apparatus, includes an oil pump which uses an internal combustion engine as a motive power source and is connected to the power transmission apparatus via an oil passage, for supplying operating hydraulic pressure to the power transmission apparatus, an accumulator connected to the oil passage and capable of accumulating hydraulic pressure, and a switching valve capable of effecting communication between the accumulator and the oil passage by opening during operation of the engine and cutting off the communication therebetween by closing during automatic stop of the engine. When it is determined that the engine is under manual stop caused by turn-off of an ignition switch of a vehicle, manual stop-time control for opening the switching valve is performed.
