SYSTEM FOR CONTROLLING REGENERATIVE BRAKING TORQUE OF ECO-FRIENDLY VEHICLE AND METHOD OF CONTROLLING SAME

Proposed is a system and method of controlling regenerative braking torque of an eco-friendly vehicle, the system and method being configured to quickly reduce and maintain a wheel slip amount less than a reference value during coasting, and accordingly, being able to achieve coasting stability and stable regenerative braking, by controlling regenerative brake into zero when a wheel slip over a reference value is generated and an Anti-lock Brake System (ABS) is turned on while an eco-friendly vehicle coasts, and by gradually increasing regenerative braking torque of a motor with a predetermined inclination from zero using Proportional-Integral (PI) control when the ABS is turned off.
