A system for preventing instability of a vehicle due to regenerative braking of a rear wheel are provided, which previously reduce a regenerative braking amount, thus securing vehicle stability and updating a regenerative brake map according to a braking situation, may include a first controller configured of distributing braking torque of front and rear wheels for a deceleration level according to a basic regenerative braking distribution ratio on a regenerative brake map on the basis of a driver demand braking amount, and configured of previously reducing a rear-wheel regenerative braking torque of the rear wheel to a first reference value or less than the first reference value in an adjustment section between first and second deceleration; and a second controller connected to the first controller and configured of further reducing the rear-wheel regenerative braking torque to transmit it to the first controller, if a wheel slip value is greater than a reference slip value according to vehicle driving information during braking of the vehicle.

    本发明提供一种用于预防后车轮的再生制动而导致的车辆的不稳定性的系统,其预先减小了再生制动量,从而根据制动情况保证车辆的稳定性并更新再生制动映射图,其可以包括:第一控制器以及第二控制器,所述第一控制器配置为基于驾驶员所需的制动量根据再生制动映射图上的基础再生制动分配比,针对减速度水平分配前车轮的制动扭矩和后车轮的制动扭矩,并且配置为在第一减速度与第二减速度之间的调节区间中将后车轮的后车轮再生制动扭矩预先减小到第一参考值或小于第一参考值;所述第二控制器连接至第一控制器,并且配置为根据车辆制动期间的车辆行驶信息,如果车轮滑动值大于参考滑动值,则进一步减小后车轮再生制动扭矩,以将其发送至第一控制器。
