Abstract: Disclosed is lateral pressure control of a continuously variable transmission (CVT) with a transmission ratio changed by changing groove widths of a drive pulley and a driven pulley, a drive force from a drive source being transmitted to a wheel. A control part controlling respective lateral pressures of the drive pulley and the driven pulley is provided. The control part sets an increase correction amount of the lateral pressure of the drive pulley to a first lateral pressure increase correction amount if the CVT is not in an in-gear state or a shift position is consistent with a traveling direction of the vehicle, and, sets said amount to a second lateral pressure increase correction amount smaller than the first lateral pressure increase correction amount if the CVT is in the in-gear state and the shift position is not consistent with the traveling direction of the vehicle.

Abstract: In a hydraulic control device switchable between a first state in which a first oil is supplied from a first pump to a hydraulic operation part via a bypass valve and a second state in which the first oil supplied from the first pump is pressurized by using the second pump and the pressurized first oil is supplied, as a second oil, to the hydraulic operation part, control that adds a correction hydraulic pressure of a predetermined amount to the hydraulic pressure of the oil discharged from a valve for adjusting the pressure of the oil supplied to the hydraulic operation part is performed when the second state is switched to the first state due to a stop or a low rotation state of the second pump.

Abstract: A hydraulic control device and hydraulic control method of a transmission are provided. The hydraulic control device of a transmission, which includes a forward clutch engaged in a Drive range, a reverse brake engaged in a Reverse range, and a switching valve that is able to selectively switch supply of a hydraulic pressure to the forward clutch and the reverse brake, wherein the hydraulic control device receives a shift position of a vehicle on which the transmission is mounted and idling stop information. When the range is switched to the Reverse range from the Drive range during idling stop, and the switching valve is positioned at a position at which a hydraulic pressure is able to be supplied to the reverse brake, rotational speed increase control with a rotational speed of an electric oil pump higher than a normal rotational speed is performed.

Abstract: Provided are a control device and a control method of a continuously variable transmission capable of preventing an endless member from slipping even when a parking lock is released. On a condition that a vehicle is in an idling stop state and a parking lock mechanism is in a parking lock state, rotation speed increase control configured to increase a rotation speed of an electric oil pump is executed so that the endless member can be prevented from slipping with respect to a driven pulley even when the parking lock mechanism is switched to a parking lock released state.
