Based on the computer Internet of Things technology, this paper analyzes the engine model of new energy vehicles, the relationship between engine efficiency and speed, and the control scheme of the engine in hybrid power, and establishes the main operating state and control method of the engine in this paper. At the same time, this paper analyzes the mathematical model of FSPM motor voltage and torque and uses MATLAB/Simulink to establish a new energy vehicle drive system. The drive system includes a magnetic flux switching permanent magnet (FSPM) motor and a motor drive module, an internal combustion engine generator module, a battery module, and a control module. The starting characteristics, running characteristics at different speeds and engine shutdown running characteristics of new energy vehicles are analyzed through simulation. Through a large amount of data and images, it can be seen that the hybrid simulation model designed based on the computer Internet of Things technology can complete most of the basic principles to keep the engine running at the most efficient.
