    摘要: A method of controlling a hybrid powertrain of a vehicle includes lowering a target voltage set point of a low voltage battery to a temporary voltage set point to reduce the overall power required by the accessory power module when a requested voltage from a vehicle accessory draws the voltage of the low voltage battery below the target voltage set point. The temporary voltage set point gradually increases over time until equal to the target voltage set point, allowing sufficient time for a high voltage battery to provide the required power for the accessory power module or for an electric motor/generator to generate the current required by the accessory power module.

    摘要: There is provided a method and an article of manufacture comprising a storage medium having machine-executable code stored therein for estimating a power loss for an internal combustion engine at a point in time. The code includes code to determine engine operating conditions. A nominal power loss is determined based upon an engine operating point. A power loss correction to the nominal power loss is determined based upon barometric pressure, engine temperature, air/fuel ratio, and catalyst temperature. The power loss correction is determinable for: an engine air/fuel ratio mode, an engine cylinder activation mode, and, an engine operating temperature mode.
