Vehicle transmission system for controlling clutch temperature

A method for controlling a vehicle transmission system, comprising:

• generating a shifting status that is indicative of an engagement and disengagement of a plurality of torque-transmitting devices;
• receiving said shifting status that is indicative of said engagement and disengagement of said plurality of torque-transmitting devices;
• calculating a temperature of said plurality of transmitting devices based at least in part upon said shifting status;
• conducting a first modification of the operation of said plurality of torque-transmitting devices if said temperature is at least substantially equal to a first predetermined temperature;
• and
• conducting a second modification of the operation of said plurality of torque-transmitting devices if said temperature is at least equal to a second predetermined temperature;
• and
• ceasing said second modification of the operation of said plurality of torque-transmitting devices if an engine parameter is less than a second predetermined temperature.

A vehicle transmission system, comprising:

• an input drive shaft configured to be driven by an engine;
• an output drive shaft configured to drive a drive mechanism;
• a plurality of torque-transmitting devices connecting said input drive shaft to said output drive shaft and configured to engage and disengage to provide a transition between a plurality of operating ratios of said input drive shaft and said output drive shaft;
• and
• a control module configured to calculate a temperature of said plurality of torque-transmitting devices based at least in part upon a downshift or upshift of said plurality of torque-transmitting devices, said control module further configured to conduct at least a first modification of the operation of said plurality of torque-transmitting devices if said temperature is at least equal to first predetermined temperature and a second modification of the operation of said plurality of torque-transmitting devices if said temperature is at least equal to a second predetermined temperature.
