Abstract: A method of controlling a towing mode of an eco-friendly vehicle, may easily charge a battery of a towed vehicle by selecting one of a charge mode during traveling, a regenerative braking charge mode, and a coasting charge mode for charging the battery of the towed vehicle when a towing vehicle tows the towed vehicle so that a motor of the towed vehicle is driven by a negative charge torque for charging the battery when the towing vehicle accelerates or decelerates, and furthermore, may easily perform the assist of the traveling driving force of the towing vehicle by selecting a discharge mode during traveling in a state in which the towed vehicle does not need to be charged to the amount of charge of the battery of the towed vehicle greater than or equal to a reference value so that the motor of the towed vehicle is driven by a positive driving torque by discharging the battery of the towed vehicle.

Abstract: The present disclosure provides a method of controlling a towing mode of an vehicle, which may easily charge a battery of a towed vehicle by allowing a motor of the towed vehicle to output a charging torque for charging the battery and allowing a motor of the towed vehicle to output a creep torque or a regenerative braking torque capable of charging the battery even upon deceleration traveling together with a compensation control of increasing engine output power of a towing vehicle compared to default output power upon acceleration and constant speed traveling by selecting one of an eco-towing mode, a power towing mode, and a target charging towing mode for charging the battery of the towed vehicle when the towing vehicle, which is a hybrid electric vehicle, tows the towed vehicle, which is an electric vehicle or a hybrid electric vehicle.
