DRIFT DRIVING CONTROL METHOD AND SYSTEM OF ELECTRONIC LIMITED SLIP DIFFERENTIAL

A drift driving control method and system of an electronic limited slip differential (e-LSD). The method and the system enable drift driving by controlling an e-LSD differential when drift driving is intended by a driver. Whether or not drift mode conditions are met on the basis of a driver’s vehicle operating state and an output value reflecting a driving state of a vehicle is determined. When the drift mode conditions are met, control is performed so that drift driving is performed by causing the vehicle to be oversteered by increasing driving force of a turning outer wheel using the electronic limited slip differential and then maintaining simultaneous slipping of right and left wheels.
