用于自主车绕障的超声传感器线阵

A Linear Array of Ultrasonic Sensor for Obstacle-Bypassing Systems of Autonomous Vehicles

根据超声波的作用机理和两种类型回波的不同振幅模式，设计了一种便于工程实现的超声传感器线阵。由该线阵采集到的数据，经过一简洁的经验专家系统，可以确定自主车前方障碍物的距离和方位。实验表明该线阵能成功地引导自主车绕过障碍物。

A linear array of ultrasonic sensor which is easy to be practically realized is designed according to thescattering mechanism of ultrasonic wave and two different echo amplitude patterns.It can get the distanceand orientation of obstacle in front of autonomous vehicle after the data gethered is processed by a simpleexpert system. The operating result demonstrates that it can guide an autonomous vehicle through anobstacle placed environment.
