Controller for variable transmission

A control system for a variable ratio transmission in a drivetrain comprising a variator and a range box, the drivetrain having a pressurized hydraulic fluid in a control path with at least one passage in the control path associated with the variator, the control system comprising:

• a plurality of sensors, each of the plurality of sensors configured to communicate a signal representing a measurement or a control state;
• a variator solenoid configured to control hydraulic pressure to the variator;
• a range clutch solenoid configured to control hydraulic pressure to a range clutch;
• a forward clutch solenoid configured to control hydraulic pressure to a forward clutch;
• a reverse clutch solenoid configured to control hydraulic pressure to a reverse clutch;
• and
• an electronic controller communicatively coupled to the variator solenoid, the range clutch solenoid, the forward clutch solenoid, the reverse clutch solenoid, the plurality of sensors, and the range box, the electronic controller configured to send a command to the variator solenoid to enable the variator, the electronic controller comprising:
• a plurality of modules configured to receive input from the plurality of sensors, the plurality of modules comprising:
• a shift logic module configured to send a command to one or more of a torque converter clutch solenoid, the range clutch solenoid, the forward clutch solenoid, and the reverse clutch solenoid to apply one or more of a torque converter clutch, the range clutch, the forward clutch, and the reverse clutch;
• and
• a shift quality control module configured to determine a rate at which each of the torque converter clutch, the range clutch, the forward clutch, and the reverse clutch is applied.
