System and method for obtaining subjective vehicle dynamics based on Internet of Things

The invention belongs to the technical field of vehicle dynamics, and discloses a system and a method for obtaining subjective vehicle dynamics based on the Internet of Things. The system for acquiring subjective vehicle dynamics based on the Internet of Things comprises a vehicle speed acquisition module, an oil quantity acquisition module, a mileage acquisition module, a main control module, a network communication module, a parameter import module, a power optimization distribution module, a data storage module and a display module. The parameter importing module has the advantages of convenience and rapidness in importing vehicle parameter data, high parameter data importing accuracy and the like. Meanwhile, the optimal distribution relation between the vehicle dynamics virtual controlquantity and the wheel slip rate and the sideslip angle is established through the power optimal distribution module on the basis of a quadratic programming method, the nonlinear coupling constraintof the tire side longitudi
