Regenerative Braking System for a Hybrid Electric Vehicle and a Corresponding Method

Abstract

A method and system for controlling regenerative braking of a hybrid electric vehicle. The regenerative braking system has a driver-operable brake pedal, a hydraulically actuated friction brake for at least one front wheel, an anti-lock braking system hydraulically connected to said hydraulically actuated friction brake, and an electrically actuated friction brake for at least one rear wheel. The regenerative braking system further comprises an electric machine connected to said at least one rear wheel and capable of performing regenerative braking of said at least one rear wheel, and an electronic control unit that controls the stability of said hybrid electric vehicle, wherein said regenerative braking system is configured to provide increased braking torque of said front hydraulically actuated friction brake by means of said anti-lock braking system for compensating a decreased or limited rear wheel braking torque initiated by said electronic control unit.
