Abstract
A vehicle includes an engine and a controller programmed to autostart and autostop the engine. In an autostopped state, engine autostarts are inhibited in the presence of transient currents caused by activation of electrical loads. Engine autostarts are inhibited for a predetermined duration after activation of the electrical load when a battery current is greater than an autostart current threshold.
