The system comprises an adaptive charge sustaining controller (31); at least one internal data source (34) connected to the adaptive charge sustaining controller; and a memory (36) connected to the adaptive charge sustaining controller for storing data generated by the at least one internal data source. The adaptive charge sustaining controller (31) is operable to select an operating mode of the vehicle's powertrain along a given route based on programming generated from data stored in the memory (36) associated with that route. Further described is a method of adaptively controlling operation of a plugin hybrid electric vehicle powertrain comprising identifying a route being traveled, activating stored adaptive charge sustaining mode programming for the identified route and controlling operation of the powertrain along the identified route by selecting from a plurality of operational modes based on the stored adaptive charge sustaining mode programming.

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.
