The invention discloses an automobile front obstacle detection and early warning device which comprises a bumper, a grid net is connected to the middle of the bumper, detection assemblies parallel to each other are arranged on the two sides of the grid net, and a plurality of distance measuring sensors arranged in parallel in the vertical direction are arranged in the detection assemblies. According to the invention, the plurality of distance measuring sensors continuously generate pulse signals, so that the plurality of distance measuring sensors can form a plurality of parallel detection planes from top to bottom, the distance measuring sensors transmit received reflected waves to the early warning display, and the early warning display classifies wavelength data through a preset data processing program; the wavelength is bound with the height of the distance measuring sensor, a virtual plane of the distance measuring sensor relative to the ground is constructed through a data processing program, and the reflecting surface of an obstacle in the range of the plane is constructed through multiple times of acquisition, so that the outline of the reflecting surface of the obstacle is displayed on the early warning display; and the early warning display gives an alarm.
本发明公开了一种汽车前方障碍物检测及预警装置,包括保险杠,保险杠中部连接有栅格网,栅格网两侧均设有相互平行的检测组件,检测组件内设有若干延竖直方向平行设置的测距传感器。本发明中若干测距传感器持续发生脉冲信号,使若干测距传感器可以在从上至下构成若干个平行的检测平面,测距传感器将接受到的反射波发射给预警显示器,预警显示器通过预设的数据处理程序对波长数据进行分类,波长和测距传感器的高度绑定,通过数据处理程序构建一个该测距传感器相对地面的虚拟的平面,通过多次获取使该平面范围内的障碍物的反射面被构建出来,从而在预警显示器上显示出障碍物的反射面轮廓,当障碍物很近时,预警显示器报警。
