Abstract

In a system and a method for controlling regenerative braking configured for maximizing vehicle energy efficiency by allowing an electrified vehicle to change a maximum regenerative braking allowance used for braking force distribution and regenerative braking control in the electrified vehicle, the method includes analyzing a driver's vehicle speed pattern based on data on a vehicle speed of a vehicle to obtain information on an energy efficiency according to a change in a maximum regenerative braking allowance, determining the maximum regenerative braking allowance in which the driver's vehicle speed pattern is considered based on the obtained information on the energy efficiency according to the change in the maximum regenerative braking allowance, and updating the previous maximum regenerative braking allowance.
