[Abstract]:With the rapid development of economy and the acceleration of urbanization, the number of vehicles and road traffic is increasing rapidly, and the problems of traffic congestion and traffic safety are becoming more and more serious. In the face of the increasing traffic demand, the intelligent transportation technology, as an effective way to solve traffic problems, has been greatly developed. The integrated use of wireless communication, control and other advanced technology of the vehicle networking system has become an important direction of development. Vehicle networking is a cross-disciplinary subject which is based on the intelligence of vehicles, including information collection, data transmission, big data processing and fusion, comprehensive application and release of information, intelligent travel services and other key technologies. It uses advanced sensor technology, wireless communication and new generation of Internet technology to realize dynamic real-time human-vehicle-environment information exchange. Based on the dynamic traffic information collection and integration, vehicle active safety control and road coordination management are carried out, which can fully realize the effective coordination between human and vehicle-environment, ensure traffic safety, improve traffic efficiency, and thus form safety. Efficient and environmentally friendly road traffic operating environment. Based on the theory and development method of HLA high level architecture, this paper designs the vehicle networking simulation platform to simulate the real vehicle networking system. The research contents of this paper mainly include: the design of vehicle networking simulation framework based on HLA; the vehicle warning simulation based on typical scene; the realization of vehicle networking simulation platform; the test and method verification. In this paper, the traffic environment generation method based on the secondary development of Q-Paramics and the simulation method of vehicle behavior control are studied. The requirements of different simulation purposes (such as function testing, scene verification, etc.) and the different stages of the whole life cycle of the system for the vehicle networking simulation system are analyzed in depth. Three simulation modules are developed: vehicle information interaction module, vehicle warning module and vehicle behavior control module. Under the support of HLA, the various modules are integrated by interface to form a multi-functional unified vehicle networking simulation platform. Through many experiments, the reliability of the simulation method of the platform and the effectiveness of the vehicle networking system are verified.
