Research on vehicle dynamics based on intelligent driving simulation test

In the process of intelligent driving simulation test, the vehicle dynamics model has a certain impact on the simulation results. In order to study how to calibrate the parameters of vehicle dynamics model based on intelligent driving simulation test, the vehicle dynamics model is built based on Carmaker dynamics software platform and real vehicle data. Select the typical test conditions, one is the test conditions for the longitudinal characteristics of the vehicle; The other is the test condition for vehicle lateral characteristics. Through the benchmarking analysis between the simulation analysis results and the field test results of the real vehicle, we can evaluate whether the longitudinal and transverse performance of the built dynamic model meets the requirements of intelligent driving simulation.
