Patent ID: 8225915

Claim:
A system for controlling a dual clutch torque converter having a first clutch and a second clutch, the system comprising: a source of pressurized hydraulic fluid; a first valve assembly having a first valve moveable between at least three positions, the first valve assembly having an inlet port in communication with the source of pressurized hydraulic fluid and having an outlet port, wherein when the first valve is in a first position the inlet port is in communication with the outlet port, when the first valve is in a second position the inlet port is in partial communication with the outlet port, and when the first valve is in a third position the inlet port is not in communication with the outlet port; a second valve assembly having a second valve moveable between at least two positions, the second valve assembly having a first inlet port in communication with the outlet port of the first valve assembly, a second inlet port in communication with the source of pressurized hydraulic fluid, a first outlet port in communication with the first clutch, and a second outlet port in communication with the second clutch, wherein when the second valve is in a first position the second inlet port is in communication with the first outlet port and the first inlet port is in communication with the second outlet port, and when the second valve is in a second position the first inlet port is in communication with the first outlet port; a first solenoid in communication with the first valve assembly and operable to selectively communicate a fluid to the first valve assembly, wherein when the fluid is in contact with the first valve of the first valve assembly the fluid moves the first valve of the first valve assembly to at least two of the first, second, and third positions; and a second solenoid in communication with the second valve assembly and operable to selectively communicate a fluid to the second valve assembly, wherein when the fluid is in contact with the second valve of the second valve assembly the fluid moves the second valve of the second valve assembly to at least one of the first and second positions.
