Abstract
A method of controlling an idle speed of an engine of a vehicle, includes the steps of determining that the engine is decelerating to or is operating at a nominal idle speed, determining that a vehicle brake is applied, determining an actual or projected electrical load of at least part of a vehicle electrical system is beyond an electrical load threshold, and increasing the engine speed to or maintaining the speed of the engine at a speed greater than the nominal idle speed range as a function of the electrical load to increase the electrical output of a generator coupled to the engine. The method may include determining that the brake is ceasing to be applied and then decreasing the engine speed to or toward the nominal idle speed.
