Patent ID: 8485931

Claim:
A vehicle comprising: an electric traction motor; an engine having an output shaft; a damper bypass clutch (DBC) assembly connected to the output shaft; a transmission having first and second clutches, wherein the clutches and the DBC assembly are selectively engaged and disengaged to select between only eight transmission operating states, and wherein the DBC assembly selectively connects the output shaft to the transmission; a fluid pump that circulates fluid for cooling the motor and for actuating the clutches; a multiplexed fluid control circuit having a variable force solenoid (VFS) and three on/off solenoid valves, including first, second, and third on/off solenoid valves, wherein the three on/off solenoid valves are multiplexed together to control flow of the fluid to the DBC assembly and to the first and second clutches, and wherein the VFS valve is operable to control line pressure to the on/off solenoids; and a controller in communication with the multiplexed fluid control circuit, wherein the controller transmits signals to the VFS solenoid and to the on/off solenoid valves to thereby select between the eight different transmission operating states.
