The present invention relates to a parking brake fail-safe control system for a vehicle having an electric vehicle axle and a method thereof. The system and the method control the torque of a first motor disposed on a first electric vehicle axle of a rear wheel and the torque of a second motor disposed on a second electric vehicle axle of the rear wheel to have the same magnitude in opposite directions, and increase/decrease the torque of the first motor and the torque of the second motor according to a change in wheel speed. Safe parking braking can be achieved on flat ground, slopes and the like.

    本发明涉及用于具有电动车轴的车辆的驻车制动器故障安全控制系统及其方法,当驻车制动器发生故障时,所述系统和方法通过将配置于后轮的第一电动车轴的第一电机的扭矩和配置于后轮的第二电动车轴的第二电机的扭矩控制为在相反方向上具有相同的大小并且通过根据车轮速度的变化,增大/减小第一电机的扭矩和第二电机的扭矩,可以在平地、斜坡等上实现安全驻车制动。
