Modeling and Simulation Analysis of Typical Series Parallel Hybrid Electric Vehicles

Aiming at the simulation modeling and analysis problem of a series-parallel hybrid vehicle, this paper establishes a series parallel hybrid vehicle model, and simulates and analyzes it from the aspects of economy, power and mode switching. Firstly, the vehicle power configuration and modes of series-parallel hybrid vehicles are analyzed and studied, and a series and parallel hybrid vehicle mode switching control model and torque distribution strategy of hybrid vehicles based on logic threshold values are further constructed in the MATLAB/Simulink platform. Through joint simulation with VPAT, the economic simulation test is carried out under WLTC working conditions, which verifies the accuracy of the established vehicle model and the reliability of vehicle mode switching.
