Transmission with creep control intervention functionality

A transmission assembly for use with a vehicle having an engine, the transmission assembly comprising:

• an input member;
• an input clutch responsive to position control signals, wherein engagement of the input clutch connects a crankshaft of the engine to the input member;
• and
• a controller in communication with a brake pedal and having multiple control modules, each of which outputs a corresponding torque command, wherein the multiple control modules include a creep controller programmed to output a calibrated creep torque, and wherein the controller includes a processor and tangible, non-transitory memory on which is recorded intervention logic, the execution of which causes the controller to independently monitor the corresponding torque commands from each of the multiple control modules during a creep maneuver, and to execute a set of control actions when predetermined conditions are present, including:
• allowing only the torque command from the creep controller to determine the position control signals of the input clutch during the creep maneuver;
• and
• setting the creep torque to zero when the brake pedal is applied.

A method of independently monitoring, during a creep maneuver of a vehicle, torque commands from each of a plurality of control modules of a controller, wherein the vehicle includes a brake pedal and an input clutch, the method comprising:

• outputting a corresponding torque command from each of the control modules, including outputting a calibrated creep torque from a creep control module;
• monitoring the corresponding torque commands from each of the multiple control modules during the creep maneuver;
• and
• executing a set of control actions via the controller when predetermined conditions are present, including allowing only the torque command from the creep controller to determine a position control signal of the input clutch during the creep maneuver, and setting the creep torque to zero when the brake pedal is applied.
