Method and system for alternator load modeling for internal combustion engine idle speed control

A computer readable medium storing a computer program comprising:

• computer readable code for monitoring a plurality of vehicle system signal inputs;
• computer readable code for determining a baseline load control signal based on the vehicle system signal inputs;
• computer readable code for determining a maximum load control signal based on the vehicle system signal inputs;
• computer readable code for determining an anticipated load control signal based on the vehicle system signal inputs;
• computer readable code for determining an idle speed control signal based on the baseline control signal and the anticipated control signal;
• computer readable code for modifying the idle speed control signal based on vehicle system signal inputs;
• and
• computer readable code for controlling the idle speed based on the modified idle speed control signal.
