The invention relates to the technical field of automobile braking, and discloses a brake control method and system for an electronic hand brake motor, and the method comprises the steps: obtaining obstacle detection data based on a preset sampling frequency, recognizing the types of a plurality of obstacles around a vehicle based on the obstacle detection data, and creating an obstacle three-dimensional model; acquiring vehicle speed data based on a preset sampling frequency, generating vehicle speed-time relation information, and generating a brake triggering judgment instruction when the vehicle speed data is smaller than a preset brake triggering speed; creating a collision warning area based on the vehicle contour, and generating a parking suppression condition signal when there is no moving obstacle in the collision warning area and the braking acceleration in the previous preset speed change observation period is smaller than a preset deceleration threshold; generating a parking suppression instruction based on the parking suppression condition signal; the method has the effect that the intelligent level of parking triggering of the automobile under the low-speed running working condition is improved.

    本申请涉及汽车制动的技术领域,公开了一种用于电子手刹电机的刹车控制方法及系统,所述方法包括基于预设的采样频率获取障碍检测数据,基于障碍检测数据识别车辆周边若干障碍物的障碍类型,并创建障碍三维模型;基于预设的采样频率获取车速数据,生成车速‑时间关系信息,当车速数据小于预设的制动触发速度时,生成制动触发判断指令;基于车辆轮廓创建碰撞警示区域,当碰撞警示区域内无移动障碍物,且在此前预设的变速观测时段内的制动加速度小于预设的减速阈值时,生成驻车抑制条件信号;基于驻车抑制条件信号生成驻车抑制指令;本申请具有提高汽车在低速行驶工况下驻车触发的智能化水平的效果。
