A method is disclosed for controlling the operation of a mild hybrid electric vehicle having an engine and high and low voltage power systems selectively connectable via a DC to DC converter. The method comprises whenever possible using only a low voltage battery forming part of the low voltage power system to power low voltage loads during an engine E-stop performed automatically to save fuel and reduce emissions and whenever possible using only a high voltage battery forming part of the high voltage power system to recharge the low voltage battery when the engine is restarted following the E-stop.
