A powertrain assembly has multiple torque actuators. The assembly includes a first controller configured to control a first torque actuator and a second controller configured to control a second torque actuator. The first controller is configured to receive a signal from an input sensor and convert the signal into a torque demand. The second controller is configured to receive the torque demand from the first controller and determine respective optimal torque allocations for the first and second torque actuators based on the torque demand and a plurality of optimization factors. The first controller includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method of controlling the multiple torque actuators across the at least two controllers via a dynamic look-up table. The dynamic look-up table is populated by a plurality of stored torque production allocation values based on a respective plurality of torque requests.
