Abstract: A control method for an electrified powertrain of an electrified vehicle having a first electric motor before a transmission and a second electric motor after the transmission includes receiving, by a control system and from a set of sensors, a set of operating parameters of the electrified powertrain, each operating parameter of the set of operating parameters relating to a torque split between the first and second electric motors, determining, by the control system, first and second optimal torque splits between the first and second electric motors for a transmission shift event by solving a torque split optimization problem based on the set of operating parameters, and controlling, by the control system, the first and second electric motors based on the first optimal torque split followed by the second optimal torque split relative to the transmission shift event.

Abstract: An optimized control system for a multi-motor propulsion system of an electrified vehicle is configured to access a calibrated surface that defines operating points corresponding to different torque requests and for enabling/disabling first and second electric traction motors of an electrified powertrain, determine an operating mode for the electrified powertrain based on the torque request and the calibrated surface, wherein the operating mode is one of (i) enabling the first electric traction motor and disabling the second electric traction motor, (ii) enabling the second electric traction motor and disabling the first electric traction motor, and (iii) enabling both the first and second electric traction motors, and control the electrified powertrain according to the determined operating mode such that the one or more enabled electric traction motors satisfies the torque request and thereby improves an efficiency of the electrified powertrain.
