Virtual Reality Based Vehicle Simulation Driver Development

In traditional training and military parade training,no matter the wind,rain,or bad weather conditions,the drivers have to train in this cruel environment.Moreover,on the one hand,this large-scale training method will cause certain wear on the real car,on the other hand,it will also consume more oil and manpower and material resources.In order to solve these practical problems,and in response to the demand of the military,the subject,with the virtual reality as the background,developing a new type of simulator based on virtual reality technology in cooperation with Beijing Raytheon Bo Feng Information Technology Co.This paper firstly analyzes the research status and development trend of analog driver simulator based on virtual reality,and puts forward a new design and implementation method of simulation driving training system based on the current development trend of analog driver simulator at home and abroad.The application of the design to the parade training can not only improve the driving level of the drivers,but also reduce the training time of the drivers,and the simulated scene is realistic,the operation is simple safe and reliability,which greatly saves the wear of the real car and the consumption of ammunition and oil.The main work of this article is as follows:First,it analyzes the development status of simulation driving training at home and abroad as well as the research significance of this subject,then introduces the main technical indexes of the simulation driving system based on virtual reality,and introduces the basic composition of the simulation driving system and complete the overall scheme design of the system from the whole.Secondly,using Unity3D as the system development software platform,the 3D simulation driving scene is built and rendered,including the model and building construction,the setting of the body collision body and the establishment of the collision model,and the dynamic control model is set up from the transmission system,the rotation system and the brake system,from the physics and mechanics.The influence of each parameter in the simulator on the system output is analyzed.Then through the military support of the military parade village in Beijing,the actual data from the car movement in the actual environment is compared with the data from the dynamic model.The accuracy of the model is verified,and the software is designed with the C#language.And implemented in Unity,so that the simulation effect is more real and stable.In order to enhance the real touch of the virtual reality system,the communication between the G27 steering wheel assembly and the three degree of freedom platform and the software system is increased.Starting from the overall realization of the system,wecompleted the construction of 3D display system and multi network communication,and ultimately realized the goal of sharing virtual reality.From the realization and performance of the system function,the calibration experiment of the key equipment and the whole system test are completed,and the form and the form of the fold line are expressed in the form of the system.Finally,the whole research content of the war chariot based simulation driving system based on virtual reality is summarized,and the main work in the system development is summarized.The analog driver simulator,designed by Beijing thunder god Bo Feng Information Technology Co.,Ltd.,has been widely used in the army,and has achieved very good results,and has been greatly praised by the military leaders.
