本文研发了一种安全车距智能预警系统.系统以AVR单片机为核心,利用超声波传感器发送和接收超声波,然后通过发送和接收的超声波信号的时间差,计算出前、后车辆之间的距离,并在车内的LCD显示器上显示出本车的车速以及与前、后车辆的距离,当与前、后车辆的车距小于安全车距时,发出报警信号,提醒本车驾车者采取相应措施,同时可给后车发出安全预警信号.
本文研髮瞭一種安全車距智能預警繫統.繫統以AVR單片機為覈心,利用超聲波傳感器髮送和接收超聲波,然後通過髮送和接收的超聲波信號的時間差,計算齣前、後車輛之間的距離,併在車內的LCD顯示器上顯示齣本車的車速以及與前、後車輛的距離,噹與前、後車輛的車距小于安全車距時,髮齣報警信號,提醒本車駕車者採取相應措施,同時可給後車髮齣安全預警信號.

This paper develops an intelligent warning system for safe distance vehicle.The system takes single chip microcomputer as the core,uses ultrasonic sensor to transmit and receive ultrasonic wave,then by the time difference between transiting and receiving the ultrasonic signals,the distance between the vehicles in front and behind can be calculated.The vehicle speed and the distance between the vehicles in front and behind can be displayed on the LCD installed inside the vehicle.When the distance between the vehicles in front and behind is less than the safe distance,the warning signals are sent,warning the driver to take corresponding measures,and also the vehicle can also send the signals to the driver in vehicle behind.
