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: An oil pressure control system of an automatic transmission for a vehicle includes a lock-up clutch, a TC regulator valve, an LC control valve, an LC shift valve, an oil cooler, a control area determination device, a torque transmission capacity calculator, a high load state determination device, and an oil pressure controller. The oil pressure controller is configured to control a TC regulator pressure outputted by a TC regulator valve, so that a torque transmission capacity of a lock-up clutch is greater than a reference torque transmission capacity calculated by the torque transmission capacity calculator, if a control area determined by the control area determination device is a complete engagement area and the high load state determination device determines that an operational state is in a high load state.
