| Abstract: | A design of ultrasonic vehicle distance early warning system is presented in this paper.MCU control technology and ultrasonic ranging technology are adopted for the warning system.The system can measure distance between obstacles and vehicles,and warn the driver to slow down the speed of the vehicle in real time,when the driver doesn′t keep the safety braking distance with obstacles.A three-dimensional sensor receiving system was adopted in the design to solve two-dimensional locating problem of obstacles.The deviation of the vehicle distance early warning system is analyzed in this paper. |
