Abstract:
A hydraulic control device that includes a second solenoid valve that is capable of supplying a resisting pressure that maintains the switching valve in the non-reverse state against the reverse range pressure, wherein the switching valve is maintained in the non-reverse state by supplying the resisting pressure from the second solenoid valve while a travel range is switched to at least a reverse range during forward travel.

Claim (Index 1):
A hydraulic control device for an automatic transmission which includes:\n an input shaft drivably coupled to a drive source of a vehicle; an output shaft drivably coupled to wheels; a power transfer path that couples the input shaft and the output shaft to each other; a meshing clutch with a synchronization mesh mechanism that is provided in the power transfer path and that allows power transfer when supplied with a hydraulic pressure; and an engagement element that is provided in the power transfer path and that allows power transfer with rotation from the input shaft reversed when supplied with a hydraulic pressure, the automatic transmission being configured to transfer rotation by connecting the input shaft and the output shaft to each other through the power transfer path when the meshing clutch and the engagement element are brought into an engaged state, and the hydraulic control device being configured to supply and discharge a hydraulic pressure to and from the meshing clutch and the engagement element, the hydraulic control device comprising: a source pressure generator that generates a source pressure; a range pressure supplier that supplies a reverse range pressure in the case where a shift speed is a reverse speed; a first solenoid valve that is capable of supplying an engagement pressure for engagement of the meshing clutch or the engagement element; a switching valve that is switchable in accordance with the reverse range pressure, the switching valve being switched to a non-reverse state in which the engagement pressure which is supplied from the first solenoid valve is supplied to the meshing clutch and a hydraulic pressure in the engagement element is drained in the case where the reverse range pressure is not supplied, and switched to a reverse state in which the engagement pressure which is supplied from the first solenoid valve is supplied to the engagement element and the source pressure is supplied to the meshing clutch in the case where the reverse range pressure is supplied; and a second solenoid valve that is capable of supplying a resisting pressure that maintains the switching valve in the non-reverse state against the reverse range pressure, wherein the switching valve is maintained in the non-reverse state by supplying the resisting pressure from the second solenoid valve while a travel range is switched to at least a reverse range during forward travel.
