Control system and method for preventing engine stalls

A control system for an engine including a starter may include a speed determination module that determines a first rotational speed of the engine during a run period contiguously following a period of starting the engine using the starter, and a speed control module that, when the first rotational speed falls below a predetermined speed greater than zero during the run period, selectively activates the starter to increase the first rotational speed. The speed control module may selectively activate the starter by selectively adjusting, based on the first rotational speed, a second rotational speed of a motor drive of the starter that supplies torque for cranking the engine and subsequently selectively engaging one of the motor drive and a first rotational member of the starter rotationally driven by the motor drive with a second rotational member of the engine. A related method is also provided.
