Research On The Design Of Driving Vehavior Evaluation And Visual Simulation Evaluation Of Practical Driving Simulator

The promotion and use of the training driving simulator is of great significance to the standardization of driving operation,the improvement of the efficiency of real vehicle training and the cultivation of driving safety awareness.In order to further improve and optimize the training effect of the practical driving simulator,this paper evaluates and designs the driving operation behavior,realizes the effective feedback of driving training,cultivates the driving safety awareness,and improves the efficiency and quality of driving training.Through the driving experience,the driving scene of the simulator is evaluated to improve the visual modeling and simulation,improve the driving reality of the simulator,and enhance the interaction between the driver and the driving simulator.In this paper,Multigen Creator and Vega Prime are selected for joint simulation to realize the establishment of driving road,environment and vehicle model required for driving training and driving experience.Under the MFC application framework of Visual Studio 2010 integrated development environment,the API library and self-defined program of Vega Prime are called to realize the dynamic driving and control of visual scene.The tripod terrain detection algorithm in Vega Prime is analyzed and selected to detect the terrain of driving scene,so as to realize the normal driving of vehicle with the change of terrain in virtual scene.Based on the multi-source information collection and fusion of serial port transmission information and userdefined detection algorithm detection information,a decision model of driving operation behavior is established.Based on the driving test standard,the deduction score of driving problems is divided into 5 points,10 points and 100 points according to the degree of error,and 25 driving behavior evaluation indexes are established respectively.The logical and modular processing of the evaluation indexes,the setting of voice response to driving errors,and the generation of final results.The higher the driving age,the less points will be deducted in the training scene,which shows that the driving training of driving simulator can achieve good training effect on the evaluation of driving operation behavior;the performance of men and women in different driving ages is at the same level,which shows that gender has little impact on driving operation behavior.In the visual simulation,six aspects,such as city,high-speed,mountain area,road scene model element analysis,interface simulation design and interactive experience evaluation,are selected to establish the evaluation index system of six first level indexes and 21 second level indexes.The weight of the index is determined by the analytic hierarchy process based on group decision theory,and the driver’s driving is adopted Driving experience,83.3% of the people think that the driving scene is very good or good,women’s scores on the driving scene model are lower than men’s,and the requirements on environmental integrity,coordination and other aspects are higher.The simulation score in bad weather is lower than other indexes,and the simulation effect in this scene still needs to be further improved.
