Abstract

Abstract: The preliminary design of the overall operation performance of diesel engines cannot be guided by actual vehicle driving tests, which hinders the improvement of the power development level and efficiency of special vehicles. By using the virtual visual simulation engine Unity3D, two virtual driving scenario models were established: a flat road scenario and an undulating road scenario. Based on the speed characteristic parameters of the engine, a diesel engine's operation performance output model was constructed. Combined with the transmission system model and the longitudinal dynamics model of the vehicle's center of mass, a straight vehicle driving dynamics model was established. By utilizing data communication technology between software platforms and setting physical quantities for bidirectional transmission, synchronous joint simulation of virtual driving scenario models and straight vehicle driving dynamics models was completed, achieving visual simulation of the virtual driving process of special vehicles in the set scenario environment. The comparison of the experimental data of actual vehicle driving shows that the straight vehicle driving dynamics model can effectively simulate the time history of calculating the speed and engine speed of special vehicles, verifying the rationality of using the model to simulate the vehicle's driving maneuverability in different scenarios.
