REGENERATIVE BRAKING SYSTEM USING REFERENCE DECELERATION DURING VEHICLE COASTING DRIVE AND METHOD THEREOF

A regenerative braking system is provided. The regenerative braking system includes: a preceding vehicle recognition module installed in a vehicle, the preceding vehicle recognition module configured to determine whether a preceding vehicle is present and measure information on a relative distance and a relative velocity to the preceding vehicle; a vehicle sensor installed in the vehicle; and a controller configured to receive information generated from the preceding vehicle recognition module and a sensor signal generated form the vehicle sensor; to generate a reference deceleration to maintain a distance from the preceding vehicle within a safety distance; to generate a driving torque command for outputting regenerative braking torque for following the generated reference deceleration; and to transfer the generated driving torque command to a vehicular driving system.
