Hydraulic control system with etrs for a continuously variable transmission

A hydraulic control system for a continuously variable transmission, the transmission having a parking mechanism, a first torque transmitting device, a second torque transmitting device, a primary moveable pulley, and a secondary moveable pulley, the hydraulic control system comprising:

• a pressure regulator subsystem providing a pressurized hydraulic fluid;
• a pulley ratio control subsystem in downstream fluid communication with the pressure regulator subsystem and configured to control the pressurized hydraulic fluid to the primary moveable pulley and the secondary moveable pulley;
• an enablement valve assembly in downstream communication with the pressure regulator subsystem;
• a range feed line connected to the enablement valve assembly, wherein the enablement valve assembly selective communicates the pressurized hydraulic fluid to the range feed line;
• a first mode valve assembly having at least one input connected to the range feed line, a first outlet port, and a second outlet port, the first mode valve assembly having a first mode valve moveable between a first position and a second position, wherein the range feed line communicates with the second outlet port when in the first position and wherein the range feed line communicates with the first outlet port when in the second position;
• a second mode valve assembly having a first inlet port in communication with the first outlet port of the first mode valve assembly, a second inlet port in communication with the second outlet port of the first mode valve assembly, a Park feed port, a Reverse feed port, and a Drive feed port, the second mode valve assembly having a second mode valve moveable between a first position and a second position, wherein the first inlet port communicates with the Park feed port when the second mode valve is in the first position and wherein the first inlet port communicates with the Reverse feed port and the second inlet port communicates with the Drive feed port when the second mode valve is in the second position;
• a first clutch actuator for selectively engaging the first torque transmitting device, the first clutch actuator in downstream fluid communication with Drive feed port of the second mode valve assembly;
• a second clutch actuator for selectively engaging the second torque transmitting device, the second clutch actuator in downstream fluid communication with the Reverse feed actuator of the second mode valve assembly;
• a park servo in communication with the Park feed port of the second mode valve assembly, the Reverse feed port of the second mode valve assembly, and the second outlet port of the first mode valve assembly, the park servo mechanically connected to the parking mechanism.
