[0004] Existing technical deficiencies: ①Generally, the development is not based on traffic accidents or dangerous driving events that occur in the real traffic environment, and it cannot realize the model construction from multi-sample traffic accidents or dangerous driving event characteristics research to typical dangerous driving simulation scenarios; ②Have Most of the driving simulators with the customization function of the vehicle-level dynamic model are car dynamic model simulators, which do not have the simulation function of truck dynamics simulation, let alone realize the simulation of the influence of liquid sloshing in the tank on the motion characteristics of the vehicle during the driving process of the liquid tank truck

[0008] Vehicle dynamics simulation software (such as carsim, trucksim, etc.) can realize vehicle dynamics simulation at the vehicle level, but it can only perform simple road traffic environment modeling, and cannot conduct highly customized driving simulations based on real road traffic environments scene development
