大型车辆超声波过弯雷达

Ultrasonic Radar for Large Vehicle Turning

利用超声波测距原理,设计大型车辆过弯雷达,在大型车辆转弯时,对车辆转弯半径内侧物体进行测距,并与设定的安全距离进行比较,做出判断。能直观地发现车辆在过弯时的安全问题,提示司机注意转弯以避免事故的发生。试验结果表明,所建立的模型能够在虚拟弯道下做出正确的判断,起到预警作用。

We design a large vehicle cornering radar base on uhrasonic ranging principle. The radar measures the distance between vehicle and the object in the inner vehicle turning radius when the large vehicle is cornering, and compares it with the safety distance. It finds the vehicle cornering safety issues intuitively and prompts driver to turn to avoid accidents. The test results show that the device could make the right judgments in virtual cornering and play a role in early warning.
