一种基于激光测距的汽车安全报警装置研究

Vehicle Safety Alarm Device Based on Laser Range-finding

为防止汽车与前方物体发生碰撞,使汽车始终在安全车速下行驶,减少事故的发生,设计了一种基于激光测距的汽车安全报警装置,它采取激光探测技术,是一种声光电一体的高科技、高智能汽车防撞产品,在出现跟车距离小于安全距离等紧急情况时,发出警报,提醒驾驶员注意并采取减速或制动措施,从而达到有效预防追尾碰撞事故发生的目的,提高了汽车的主动安全性能。测试结果表明,在输入报警距离与制动距离时,均能实现不同方式的报警。

To prevent collision with the car in front of the car,so that the car being always in a safe driving speeds and reduce accidents,a vehicle safety alarm device was designed based on laser range-finding.It used laser detection technology and was a high-tech,high intelligent vehicle impact-proof,with voice,light and electical technology integrated.When the emergency situations that the distance was less than a safe distance happened,it could give the alarm and reminded drivers to pay attention to slow down or brake,so as to achieve effective prevention of rear-end collision and improve car＇s active safety performance.The test result showed that it could achieve different ways of warming,when inputting the data between warming distance and braking distance.
