Establishing And Simulation Of The Engine Model On Driving Simulator

In recent years, system simulation technology is an unprecedented development, the simulator as the simulation technology and product expertise combined with a growing number of fields in the application. Car driving simulator as an effective tool has been widely used in driver training, traffic safety, scientific research and other fields.Driving simulator performance of the car needs, driving environment in the simulation, the vehicle dynamics, transportation engineering, computer simulation, graphics, digital audio, sensor, network communications, multi-disciplinary, multi-category comprehensive application of technology. Establish an efficient and accurate engine model is to achieve high performance, high-fidelity driving simulator car an important part.Relying on this "National Road Safety Action Plan for Science and Technology," the subject of five sub-topics, type of vehicle driving simulator to train in the engine simulation model for the study, according to the characteristics of the engine, use the appropriate method to establish the engine simulation model to study the The model of the solution method, and proven engine model used in Peixun cars driving simulator. The main thesis work and findings are as follows:first in-depth study of the modeling approach, combined with the external characteristics of the engine functions and proposed a mathematical model of the subject engine, using C++programming solver on the model. In comparison to the iterative method, based on the analysis, the choice of SOR method to determine the parameters. Gives the engine a complete mathematical model solution process, fitting step, linear interpolation procedure. Second, the use of VC++compiled run the simulation engine to achieve. Under the conditions of the limited measured data to achieve a continuous condition of the simulation engine. Concludes with the engine model validation methods, and experimental results and the measured experimental data is analyzed and compared, results showed that the accuracy and effectiveness of the engine model.This established engine simulation model has been in the car driving simulator (emulator) has been applied in the actual system, better able to simulate a certain type of vehicle engine characteristics. The results show that the proposed idea of the correct modeling of engine, built by the engine model type can be used for training simulators. Car driving simulator with the traditional model of the engine compared to the paper model has higher accuracy, higher fidelity driving simulator-based training is conducive to the promotion, to improve the quality and efficiency of our driver training will definitely help.
