The Design And Implementation Of Lane-changing Dring Assistance System Based On CVIS

As a common driving behavior in road traffic,Lane-changing can improve the driving efficiency of the vehicle effectively.Because of the complexity of the road,the driver is easy to make a mistake in judgment when crossing the road,which threaten the safety of people and vehicles.Vehicles can get the information about vehicles and road with the help of the CVIS,which improves the perception of the surrounding environment and enhances the vehicle's active safety performance.Based on the CVIS,this paper makes a depth study on the overall design scheme and the roadway safety assist model of the vehicle lane changing system,and realizes the lane changing system under the environment of the CVIS.Firstly,on the basis of analyzing the requirements of the CVIS and lane changing system,the frame structure and function of vehicle lane changing system are designed,and the working principle of lane changing system is established.Secondly,based on the analysis of the track behavior,a trajectory model based on comfort is proposed based on the analysis of the sine function trajectory model,and the minimum safe distance model of the vehicle in front of the lane and the original lane and the target lane is deduced and calculated.Thirdly,the hardware system architecture of system communication,vehicle information collection and terminal processing is established,and the system is completed by designing MK5 and Android terminal.Finally,the auxiliary test scenario is established in the CVIS,and the relevant modules and the overall function of the lane aided system are tested and analyzed.The result shows that the system modules are running well and can get information precisely,and the communication is meets the needs of the system.The track path model can reflect the road driving under natural driving.The system has high accuracy and stability in the roadway proposal,and meets the system functional design requirements and the actual traffic environment in the vehicle lane aided application requirements.which improves the active safety of vehicle.
