| Abstract: | 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. |
