    摘要: A method of controlling an electric vehicle including an internal combustion engine, a battery having a state of charge (SOC) and an open circuit voltage (OCV), includes establishing a system for estimating battery SOC. The system includes (i) a parameter estimation subsystem including a recursive parameter estimator for identifying battery parameters and (ii) an OCV estimation subsystem including a nonlinear adaptive observer for estimating battery OCV. Estimated battery OCV is related to estimated battery SOC by a mapping. An output is generated based on the estimated battery SOC.

    摘要: A method for determining a power capability for a battery includes the step of defining at least one equation based on a circuit model for the behavior of the battery. The equation includes a plurality of battery parameters, including a battery current. The value of at least one of the battery parameters is measured, and the battery current is solved-for from the at least one equation. A limiting battery current is defined based at least in part on the battery current. A limiting battery voltage is determined, and the power capability of the battery is determined based on the limiting battery current and the limiting battery voltage.

    摘要: A method for controlling a hybrid powertrain system includes the steps of determining a first power state of the hybrid powertrain system, limiting electrical power generated by a generator to the minimum of the rated power limit of the generator and the first power state, when the first power state is greater than zero, and limiting the electrical power generated by the generator to zero, and limiting the power limit of an electric machine during generating to a first operating condition of the hybrid powertrain system, when the first power state is less than or equal to zero, to provide over-charge protection to the battery. The method further includes steps that provide over-discharge protection to the battery.
