To enhance the computational speed of the hybrid transmission clutch and hydraulic system model, this paper employs the Neural Ordinary Differential Equations (NODEs) to reduce the order of the physical model. Initially, a pseudo-random number method is utilized to generate model inputs and obtain simulation results. Subsequently, the time-series data of system state variables are extracted as samples to train the NODEs model. The comparison between the physical model and the NODEs model reveals that the latter possesses excellent precision and generalization capabilities, significantly enhancing computational speed.
