The invention discloses a power safety guarantee control method and system for automatic driving of an electric automobile, multiple groups of Gaussian pulse devices are mounted on the surface of the electric automobile, and each group of Gaussian pulse device is composed of a transmitting unit, a reference unit, a beam splitting unit and a coupling unit; the method comprises the following steps: starting an emission unit to emit Gaussian pulses, vertically emitting the Gaussian pulses to a beam splitting unit to perform beam splitting processing to obtain two groups of Gaussian split beams, performing spectral interference by using the two groups of Gaussian split beams to obtain an interference beam, and solving the dynamic driving distance between the electric vehicle and the obstacle according to the phase change of the interference beam. And the driving speed of the electric vehicle is adjusted in real time according to the dynamic driving distance. In this way, the calculation efficiency of the distance between the intelligent automobile and the front object can be improved, and therefore the braking effect of the electric automobile on power during automatic driving is improved.

    本申请公开了一种用于电动汽车自动驾驶的动力安全保障控制方法及系统,其在电动汽车的表面安装多组高斯脉冲装置,每组高斯脉冲装置由发射单元、参考单元、分束单元及耦合单元构成,当电动汽车开始行驶时,启动发射单元发射高斯脉冲,并将高斯脉冲垂直入射至分束单元执行分束处理,得到两组高斯分束,利用两组高斯分束执行光谱干涉,得到干涉光束,根据所述干涉光束的相位变化,求解得到电动汽车距离所述障碍物的动态行驶距离,根据动态行驶距离实时调整电动汽车的行驶速度。这样,可以提高对智能汽车与前方物体的距离计算效率,从而提高电动汽车在自动驾驶时对动力的制动效果。
