  • Control method to bias hybrid battery state-of-charge to improve autostop availability for light-electrification vehicles
    Patent number: 9126496
    Abstract: Method for adjusting a state-of-charge within an electrical energy storage device of a hybrid powertrain system includes monitoring a plurality of electrical energy storage device parameters and determining a discharge power capability of the electrical energy storage device based on the monitored plurality of electrical energy storage device parameters. If the discharge capability is less than a first threshold, a state-of charge adjustment mode is activated. The state-of-charge adjustment mode includes increasing a commanded state-of-charge to an elevated state-of-charge to increase the discharge capability to achieve the first threshold and maintaining the commanded state-of-charge at the elevated state-of-charge until the discharge capability achieves the first threshold.
