Research On Some Driving With Car-following Model Based On Sensor

Driving car-following model based on multi-sensor fusion,driving data is obtained by combining hardware and software,according to dry pavement ? wet pavement,icy and snowy pavement to judge whether the car has safety problems in driving.Thus,it can prevent traffic accidents and improve road safety to intervene the driving alarm or emergency braking.In view of the existing car-following model,the conneetion between the systems is not close enough,and the research and analysis of the road condition is not enough,which can cause the problems of high efficiency false alarm rate and false alarm rate,therefore,it is of important significance to build a car-following model according to different road conditions?exiting model strengths and weakness.System hardware circuit uses master-slave control system,Single-chip microcomputer controls the whole hardware circuit,which mainly contains distance and speed measuring module with ultrasonic sensor and infrared sensor?multi-terrain select module,liquid crystal display module,audio and video voice alarm module,brake modules.Using C language as the programming language,the software design is accomplished by using the module analysis method in combination with the hardware circuit to realize the function of the system.keil-u Vision4 and Proteus software jointly complete the simulation of software and hardware system,the system key circuit information and liquid crystal display parts are simulated on SCM development board.According to different road condition established the driving car-following model which is simulated by MATLAB software,and design the driving car-following model system simulation software.Finally,a set of information collection,display,sound and light alarm,active braking,mode selection as an integrated vehicle driving and vehicle model.Simulation results show that driving car-following model can set up different model according to different road conditions.In the simulation,the system can make corresponding responses according to the different speed of the car,Alarm display control panel is simple,friendly interface.The system has high environmental adaptability and can improve the safety of car driving.
