Abstract
A stop/start system of a vehicle autostops and autostarts an engine and, in response to an identification of a drive cycle destination indicating that the vehicle will remain parked for at least a predefined period of time, prevents autostopping of the engine during the drive cycle to increase a state of charge of the battery above a nominal target state of charge.
Claims11
A stop/start vehicle comprising:
- an engine;
- a battery having a nominal target state of charge;
- and
- a stop/start system programmed to, in response to an identification of a drive cycle destination for the vehicle, increase the target state of charge for the battery above the nominal and control, during the drive cycle, an automatic stopping and starting of the engine to charge the battery to the increased target state of charge.

A method for controlling a stop/start vehicle comprising:
- in response to identifying a drive cycle destination indicating that the vehicle will remain parked for at least a predefined period of time,
- increasing a target state of charge for a battery above a nominal value generally maintained in the absence of identifying a drive cycle destination indicating that the vehicle will remain parked for at least a predefined period of time,
- inhibiting automatic stopping of an engine until a state of charge of the battery achieves the increased target state of charge, and
- automatically stopping and starting the engine to generally maintain the state of charge of the battery at the increased target state of charge.

A stop/start vehicle comprising:
- an engine;
- a battery having a nominal target state of charge;
- and
- a stop/start system programmed to autostop and autostart the engine and to, in response to an identification of a drive cycle destination indicating that the vehicle will remain parked for at least a predefined period of time, prevent autostopping of the engine during the drive cycle to increase a state of charge of the battery above the nominal.
