电动自行车避碰预警及制动系统的设计研究

Electric Bicycle Collision Alert and Braking System Design Research

本文对目前汽车上碰撞预警以及主动制动功能的深入分析与研究,针对现有电动自行车在该功能上的研究空白,根据电动自行车自身的特性运用通讯技术、控制技术和交通流理论,提出一种基于超声波测距和单片机控制的电动自行车碰撞预警及主动制动系统设计方案。通过运用超声波测距原理,声光报警原理以及STC12C5A60S2单片机,设计声光报警和主动制动模块,实现电动自行车碰撞预警及主动制动的功能。本文研究在降低电动自行车的交通事故发生率,减少人民的财产损失,保障人民的安全出行等方面具有重要现实意义。

This paper analyses and studies the current vehicle collision warning and active braking functions. Considering the existing functional blank of electric bicycle and the characteristics of electric bicycle, this paper puts forward a method based on ultrasonic distance measurement with single chip microcomputer controlling the system of electric bicycle collision warning and active braking, which also rues the technology of communication and control and theory of traffic flow. By applying the principle of ultrasonic distance measurement and sound and light alarm and STC12C5A60S2, the module ofsoun＇fl and light alarm and active braking can realize the function of electric bicycle collision warning and active braking with single chip microcomputer. To reduce the electric bicycle accidents and the damage to people＇s property, the design of this essay is of great significance for ensuring safe travel.
