Techniques for segmented monitoring of powertrain propulsive torque in electrified vehicles

A control method for an electrified powertrain of an electrified vehicle, the control method comprising:

• performing, by a main control system, a sequence of first processes based on an initial input including a set of signals indicative of at least one of a driver torque request and expected vehicle behavior and other intermediary inputs to generate a sequence of first outputs;
• performing, by a secondary monitoring system distinct from the main control system, a sequence of second processes based on the initial input and other intermediary inputs to generate a sequence of second outputs;
• rationalizing, by the secondary monitoring system, each first output by comparing it to its respective second output;
• when rationalized, using, by the secondary monitoring system, the particular first output as a subsequent intermediary input for both the main control system and the secondary monitoring system;
• when not rationalized, using, by the secondary monitoring system, the particular second output as the subsequent intermediary input;
• and
• using, by the secondary monitoring system, a rationalized final first output or a final second output to generate control commands for torque actuators of the electrified powertrain,
• wherein the rationalizing of the first outputs during the sequences of first and second processes is configured to reduce or eliminate false positive malfunction detections in the main control system.
