The invention discloses an anti-collision method and system for an electric vehicle door, and relates to the technical field of electric vehicle door protection.The anti-collision method comprises the steps that an ultrasonic radar is installed on the lower edge of the electric vehicle door, and before the electric vehicle door is opened, the radar emits ultrasonic waves and detects the distance between an obstacle and the radar; based on the distance between the detected obstacle and the radar, collision risk analysis is carried out, and the collision risk probability is calculated; and based on the collision risk probability, recommending countermeasures. The ultrasonic radar technology is utilized, the ultrasonic radar is installed on the lower edge of the electric vehicle door, surrounding obstacles can be actively detected before the electric vehicle door is opened, the ultrasonic radar monitors the distance between the obstacles and the radar in real time by transmitting ultrasonic signals, and therefore the distance between the obstacles and the electric vehicle door is obtained; the system can carry out collision risk analysis, calculate the collision risk probability and recommend corresponding countermeasures according to the calculation result, so that the safety of the electric vehicle in the using process is higher.
本发明公开了一种电动车门防碰撞方法及系统,涉及电动车门防护技术领域,防碰撞方法包括:在电动车门的下边缘安装超声波雷达,在电动车门开启之前,雷达发射超声波,检测障碍物与雷达的距离;基于检测障碍物与雷达的距离,进行碰撞风险分析,对碰撞风险概率进行计算;基于碰撞风险概率,推荐应对措施。本发明提出利用超声波雷达技术,在电动车门的下边缘安装超声波雷达,能在电动车门开启之前主动探测周围障碍物,超声波雷达通过发射超声波信号,实时监测障碍物与雷达的距离,从而获取障碍物到电动车门的距离,基于此数据,系统可以进行碰撞风险分析,计算碰撞风险概率,并根据计算结果推荐相应的应对措施,使电动车在使用过程中的安全性更高。
