摘要： A method for operating an engine includes defining a two-dimensional search region based upon an input power transmittable between the internal combustion engine and an electromechanical transmission. The method further includes iteratively dividing the two-dimensional search region into a plurality of subregions based upon one of the input power and the input speed, iteratively determining an engine operating point within each of the subregions, iteratively calculating an operating cost to operate the internal combustion engine and the electromechanical transmission to meet the operator torque request for each engine operating point within each of the subregions, and iteratively identifying the subregion having a minimum operating cost to meet the operator torque request. A preferred engine operating point is determined based upon the engine operating point within the identified subregion having the minimum operating cost to meet the operator torque request.

摘要： A method for controlling an input torque provided to a transmission includes executing a first iterative search within a first range of permissible torque values to determine a first torque value based on a first cost value. The first cost value is based on a first set of powertrain measurements measured at a first time. A second cost value based on a second torque value and the first set of powertrain measurements measured at the first time is calculated. The second torque value is determined using a second set of powertrain measurements measured at a second time prior to the first time. One of the first torque value and the second torque value is then selected based on the first cost value and the second cost value.

摘要： A method for controlling a hybrid powertrain system includes employing a system constraints function to identify a feasible solution for an objective variable that satisfies a plurality of independent and dependent constraints for an objective function. The objective variable is associated with a parameter of the hybrid powertrain system. Upon determining that the system constraints function fails to provide a feasible solution for the objective variable that satisfies all of the independent and dependent constraints, a problem recomposition scheme is executed to remove all of the dependent constraints and then reapply and adjust selected ones of the dependent constraints to obtain a feasible solution for the system constraints function that achieves a preferred state for the objective variable.

摘要： Methods and systems are provided for controlling an electrical system of a vehicle. Sensors are used to obtain first data for a first path of calculations and second data for a second path of calculations. The first path comprises a first plurality of calculations of generating a value of a parameter pertaining to the electrical system, and the second path comprises a second plurality of calculations of monitoring the electrical system with respect to the first path. A processor is coupled to the plurality of sensors, and is configured to determine whether a data frozen flag is active, perform the first plurality of calculations of the first path using the first data if the first data flag is inactive, and perform the second plurality of calculations of the second path if the first data flag is active.
