Abstract:
A hydraulic control system for a continuously variable transmission includes a pressure regulator subsystem, a ratio control subsystem, a torque converter control (TCC) subsystem, a variable lubrication control subsystem, a variator clamping subsystem, and a clutch control subsystem. The variable lubrication control subsystem allows for increased and decreased oil flow to components of the variable transmission based on demand. The pressure regulator subsystem provides binary line pressure control to the lubrication subsystem.
