Abstract

A method for controlling braking of a regenerative braking co-operative control system for a vehicle may include detecting, by a controller, whether a brake pedal is manipulated, determining, by the controller, a driver demand braking force, a wheel deceleration, and wheel slip when the brake pedal is manipulated, comparing, by the controller, the determined wheel deceleration value and the wheel slip value with a predetermined threshold deceleration value and a predetermined first threshold slip value, respectively, and determining, by the controller, a maximum road frictional force when the wheel deceleration value is larger than the threshold deceleration value and the wheel slip value is larger than the first threshold slip value and determining a regenerative braking force of driving wheels in accordance with the determined maximum road frictional force.

Description

technical field [0001] The invention relates to a braking control method for a regenerative braking cooperative control system of a vehicle. And more particularly, the present invention relates to a method of controlling braking of a vehicle by distributing braking force in a regenerative braking cooperative control system of an environmentally friendly vehicle driven by an electric motor, such as a hybrid vehicle or an electric vehicle. Background technique [0002] As is well known, regenerative braking is performed when braking is performed using a motor-driven vehicle, ie, an environmentally friendly vehicle such as an electric vehicle (EV), a hybrid vehicle (HEV), or a fuel cell electric vehicle (FCEV). [0003] When the vehicle is driven, the regenerative braking system of the environment-friendly vehicle converts the kinetic energy of the vehicle into electric energy while braking the vehicle, so as to store the electric energy in the battery, and then reuse the elect...
