Description

technical field [0001] The present invention relates to virtual reality technology, mechanical transmission technology, computer graphics, three-dimensional real-time rendering technology, computer interface technology, data communication technology, etc., and particularly relates to an immersive virtual driving behavior intelligent evaluation method and simulation system. Background technique [0002] The high-speed rail driving simulator constructs a driver-virtual scene interactive driving environment through manipulation simulation, dynamics simulation, visual simulation and other systems. In the virtual scene simulation, in order to truly simulate the road traffic environment, it is necessary to add moving objects such as vehicles to the scene. These moving objects simulate the corresponding behavior in the real world, and can perceive the environment in real time, and plan, make decisions and operate by themselves. Such autonomous, reactive, and capable objects that ca...

Problems solved by technology

However, when the application environment changes over time and the agent system exhibits non-stationary characteristics, the decision control model constructed by the above modeling method is prone to distortion or failure

[0005] However, based on the existing technology, the object-oriented method cannot be applied more carefully in the analysis of the high-speed rail dynamic system. error, resulting in inaccurate results
