The invention provides a braking method and system for automatic driving. The braking method comprises the steps that the target opening degree and the braking emergency level of a brake pedal are obtained; converting the target opening degree of the brake pedal into a brake pedal opening degree sequence according to the brake emergency level, wherein the brake pedal opening degree sequence comprises at least one brake pedal execution opening degree which is sequentially arranged from small to large; and determining and sequentially outputting a brake fluid pressure signal corresponding to each brake pedal execution opening in the brake pedal opening sequence according to preset pedal opening-brake fluid pressure data. The invention further provides a braking system for implementing the braking method. The braking system comprises a braking feeling simulation device and a control device. According to the braking method and system for automatic driving, the problems of sudden braking and sudden stop occurring in the braking process of the automatic driving vehicle can be solved, and comfortable riding experience is provided for passengers.

    本发明提供了一种用于自动驾驶的制动方法及系统。上述的制动方法包括:获取制动踏板目标开度和制动紧急等级;根据上述制动紧急等级将上述制动踏板目标开度转化为制动踏板开度序列,上述制动踏板开度序列包括由小到大依次排列的至少一个制动踏板执行开度;以及根据预设的踏板开度‑制动液压力数据确定并依次输出上述制动踏板开度序列中每一个制动踏板执行开度所对应的制动液压力信号。本发明还提供了实现上述制动方法的制动系统,包括制动感觉模拟装置和控制装置。根据本发明所提供的用于自动驾驶的制动方法及系统,能够解决自动驾驶车辆在制动过程中出现的“急刹、急停”问题,给乘员一种舒适的乘车体验。
