随着我国私家车的数量不断增加,以及驾驶技能,路况等复杂因素的影响,交通事故也在逐年递增,因此就汽车新技术的研究面临着更多的汽车安全问题。为了保证驾车更加安全,有必要研究新型自动刹车系统,该系统可以利用单片机作为其主控制模块,附以超声波与霍尔传感器设计相应的硬件电路,可以实现在突发状况下的自动刹车,设计原理比较简便,且满足实时性与稳定性的要求,可更好的降低车辆损伤及保证驾驶员的生命安全。
With the increasing number of private cars in our country, as well as the impact of driving skills, traffic conditions and other complicated factors, traffic accidents are also increasing year by year. Therefore, the research on new automobile technologies faces more problems of automobile safety. In order to ensure driving safer, it is necessary to study a new type of automatic brake system. The system can use the single chip microcomputer as its main control module, with the hardware circuit corresponding to the design of the ultrasonic sensor and the Hall sensor, so as to realize the automatic brake under unexpected conditions and the design The principle is relatively simple, and meet the requirements of real-time and stability, can better reduce vehicle damage and ensure driver’s life safety.
