description Disclosed is an electronic braking force distribution system for a vehicle, comprising: a normal force ratio calculation module receiving an input of a normal force of each wheel and calculating a normal force ratio; a wheel braking torque determination module receiving an input of a required braking force of the whole vehicle, and determining a braking torque of each wheel based on the normal force ratio calculated by the normal force ratio calculation module by using the received required braking force; and a motor/hydraulic braking force distribution module distribution the braking force for each wheel by using a motor braking method and a hydraulic braking method in accordance with the braking torque determined by the wheel braking torque determination module. The wheel braking torque determination module is configured to determine whether a change volume of the normal force ratio in accordance with time is equal to or lower than a certain critical value, to maintain the braking torque between wheels, which is already determined, in a section where the change volume is lower than the certain critical value as a result of the determination, and to calculate the braking ratio between the relevant wheels in accordance with the normal force ratio in a section where the change volume is higher than the certain critical value as a result of the determination. As such, according to the electronic braking force distribution system for a vehicle, the system is configured to maintain a braking ratio between relevant wheels in a section with no great change in the normal force ratio between the relevant wheels from 0.5, thereby preventing the generation of a feel of difference in driving due to frequent changes in the braking ratio in a four-wheel independent motor system. 차량의 전자 제동 분배 시스템이 개시된다. 각 휠의 수직항력을 입력받아 수직항력비를 계산하는 수직항력비 계산 모듈; 차량 전체의 요구 제동력을 입력받고, 입력받은 요구 제동력을 이용하여 상기 수직항력비 계산 모듈에서 계산된 수직항력비를 기반으로 각 휠의 제동 토크를 결정하는 휠 제동 토크 결정 모듈; 상기 휠 제동 토크 결정 모듈에서 결정된 제동 토크에 따라 모터 제동 방식 및 유압 제동 방식을 이용하여 각 휠에 대한 제동력을 분배하는 모터/유압 제동 분배 모듈을 포함하고, 상기 휠 제동 토크 결정 모듈은, 상기 수직항력비의 시간에 따른 변화량이 소정 임계치 이하인지 판단하고, 판단 결과 소정 임계치보다 작은 구간에서는 이미 결정된 휠 간의 제동 토크를 그대로 유지하고, 판단 결과 소정 임계치보다 큰 구간에서는 상기 수직항력비에 따라 해당 휠간의 제동비를 계산하도록 구성된다. 상술한 차량의 전자 제동 분배 시스템에 의하면, 휠 간의 수직항력비가 0.5를 중심으로 크게 변화가 없는 구간에서는 해당 휠 간의 제동비에 변화를 주지 않고 그대로 유지하도록 구성됨으로써, 4륜 독립 모터 시스템에서 잦은 제동비 변화로 인한 주행 이질감이 발생하는 것을 방지할 수 있는 효과가 있다.
