Control systems and methods for an electrified powertrain of an electrified vehicle include 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 and 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. The secondary monitoring system then attempts to rationalize each first output relative to its respective second output. Based on the rationalization, one of these outputs is used as an intermediary output in the sequence until a rationalized final output is obtained and used to generate control commands for torque actuators of the electrified powertrain.
