REGENERATIVE BRAKING CONTROL SYSTEM AND A METHOD FOR ECO-FRIENDLY VEHICLES IN A TOW MODE

A regenerative braking control system and method for eco-friendly vehicles in a tow mode adjusts a regenerative braking torque of a towed vehicle depending on the driving situation of a towing vehicle based. The adjustment is determined using a tension detection signal from a load cell on a tow bar. In other words, the regenerative braking torque of the towed vehicle is decreased when the towing vehicle is accelerating or is driving uphill, or increased when the towing vehicle is decelerating or is driving downhill, thereby being capable of preventing an insufficient sense of acceleration of the towing vehicle. In addition, when the tension applied to the tow bar is greater than or equal to a reference durability tension, a driving torque to drive the towed vehicle is increased, thereby being capable of preventing the tow bar from being detached or damaged due to excessive tension.
