Control system and method for preventing engine stalls

A control system for an engine including a starter for starting said engine by cranking, the control system comprising:

• a speed determination module that determines a first rotational speed of said engine during a run period contiguously following a period of starting said engine using said starter;
• and
• a speed control module that, when said first rotational speed is less than a first predetermined speed during said run period,
• determines a difference between said first rotational speed and a second predetermined speed, wherein said first predetermined speed is greater than zero, and wherein said second predetermined speed is greater than said first predetermined speed,
• prevents said engine from stalling including selectively activating said starter when said difference is greater than a predetermined difference,
• activates said starter to increase said first rotational speed by selectively adjusting a second rotational speed of a motor drive of said starter, wherein said starter supplies torque for cranking said engine, and
• subsequent to said activating of said starter, selectively engages one of said motor drive and a first rotational member of said starter, wherein said first rotational member is rotationally driven by said motor drive and engages with a second rotational member of said engine.
