Abstract: In an embodiment, a method is provided for controlling a plurality of converters that are coupled to a plurality of cells of a rechargeable energy storage system (RESS) and configured to supply electric current to other systems that require the electric current, the method including obtaining, via one or more sensors, cell data as to the plurality of cells, the cell data including a state-of-charge for each of the plurality of cells; obtaining other system data as to the other systems, including an amount of electric current required by the other systems; and controlling the plurality of converters, in accordance with instructions provided by a processor, based on both: the cell data, including the state-of-charge for each of the plurality of cells; and the other system data, including the amount of electric current by the other systems.

Abstract: A powertrain includes a propulsion system having first and second torque sources, and first and second drive axles respectively connected to and independently driven by the first and second torque sources. A permissible range of torque contribution from the torque sources to the respective first and second drive axles is defined by a component torque window. The powertrain includes sensors for detecting a dynamic driving maneuver of a vehicle having the powertrain. A controller executes a method to adjust a size and/or orientation of a chassis torque window during the detected dynamic driving maneuver, determine an optimally efficient axle torque operating point that falls on a torque line within the component torque window in proximity to the chassis torque window, and command the torque contribution via transmission of torque control signals to the first and second torque sources to achieve the optimally efficient axle torque operating point.

Abstract: A controller for an electric vehicle having an electric motor is provided. The controller includes a motor control processor (MCP) module configured to control torque output of the electric motor. The controller also includes a first main processor monitor (MPM) module and a second MPM module. The first MPM module and the second MPM module are configured to separately determine a state of health of the MCP module, and to generate a first fault signal and a second fault signal, respectively, after determining the MCP module is not functional. The controller further includes a voting control module configured to receive at least one of the first fault signal from the first MPM module, and the second fault signal from the second MPM module, and to generate an override command when it receives both the first fault signal and the second fault signal. The override command overrides the MCP module.
