Abstract

The invention provides a vehicle dynamics model and real-time scene joint simulation system and method. The system comprises vehicle scene real-time simulation software which operates road network information collected from a real map; a vehicle dynamics simulation software which comprises a vehicle dynamics model running in real time; a real-time simulation machine which comprises a signal conditioning board card and an interface, the vehicle scene real-time simulation software and the vehicle dynamics simulation software being jointly loaded to the signal conditioning board card; a global navigation satellite system simulator which is connected with the vehicle scene real-time simulation software and receives the longitude, latitude and altitude information transmitted by the vehicle scene real-time simulation software, performs GPS signal simulation on a current satellite signal according to the received information and sends an RF signal to a global navigation satellite system signal transponder; and the global navigation satellite system signal transponder which is used for forwarding the GPS signal of the global navigation satellite system simulator to a navigation display screen of a driving simulator through radio waves.

Description

technical field [0001] The invention relates to the technical field of vehicle simulation, in particular to a vehicle dynamics model and real-time scene joint simulation system and method. Background technique [0002] According to the characteristics of the existing development and verification test methods of ADAS, ADAS vehicle-in-the-loop simulation development platforms emerge in endlessly by using the combination of virtual reality and real-time simulation technology. In the same way, either because the vehicle dynamics model of the simulation software is not professional enough to truly represent the vehicle dynamics characteristics, or because of the difference in test hardware, it is impossible to completely simulate the real scene of the vehicle. Especially the application of vehicle-in-the-loop simulation in GPS positioning simulation is still lacking. Contents of the invention [0003] The purpose of the present invention is to provide a vehicle dynamics model ...
