Research And Development Of Vehicle Speed Limit System Based On Vehicle Networking

In the present stage of our country with the growing number of family cars,road traffic conditions are getting worse,some speeding driver bring great risks to road safety,in order to prevent such security risks,this paper aims to vehicle speed system and vehicle network system integration,establishing the vehicle speed system based on vehicle networking,for the real-time control of vehicle speed,avoid speeding behavior,so as to guarantee the safety of the vehicle.By installing the vehicle terminal on the vehicle,the vehicle speed limit system based on the car network can realize the collection,storage and transmission of the information about the various working conditions of the vehicle.It combines the vehicle network system with the general speed limit system,The server obtains real-time changes in the external environment and determines a speed limit to achieve an active limit on the speed of the vehicle to ensure that the vehicle in the encounter special sections and bad weather environment can also be guaranteed to travel in the safe speed,so as to avoid speeding Of traffic accidents.In order to further verify the reliability and validity of the vehicle speed limit system based on the car network,this paper uses MATLAB simulation software to design and control the simulation model of vehicle speed control system based on PID control,and analyzes and studies the systematically.The main work and achievements of this paper are as follows:1.Aiming at vehicle speed limit system,vehicle networking technology is adopted to establish vehicle speed limit system based on vehicle networking;2.A calculation algorithm of speed limit is proposed;3.Build the basic model of vehicle speed control system,designs two kinds of mechanical type throttle control speed limiting device,establish a feedback control system based on PID,MATLAB and Simulink toolbox in the establishment of model and simulation analysis by using.Finally,this paper summarizes the work,and further analyzes and forecasts the hardware and software of the vehicle terminal based on the vehicle network speed limit system.
