Abstract
A method for controlling a locking differential includes determining a temperature-dependent reference voltage at which a coil locks the differentia, determining an electric potential of a battery, using the battery to energize the coil and lock the differential, if the electric potential is equal to or greater than the reference voltage for a current temperature, and maintaining the differential unlocked, if the electric potential is less than the reference voltage.
