ABSTRACT:
A system for controlling the idle speed of an automotive engine selects a desired initial idle speed based on a sensed value of at least one engine operating parameter and operates an idle speed module to maintain the engine's idle speed at the desired initial speed. Thereafter, the system determines a desired total heat build for the engine as a function of at least one engine operating parameter and adjusts the idle speed according to a calculated actual heat build for the engine while the engine is operating.
