Validation of a hybrid electric vehicle dynamics model for energy management and vehicle stability control

摘要

A Simulink Hybrid Electric Vehicle dynamics model for the control of energy management and vehicle stability is developed. The model encompasses a transitional vehicle speed input parameterized by the New European Driving Cycle. Internal combustion engine torque, motor torque and varying corner radii are set to the same time constraints as the drive cycle. Lateral acceleration, yaw rate and tyre data are validated against measured car data, resulting in a simulation model that can be utilised (with modifications) as a tool to determine stability control and power deployment for front-wheel, rear-wheel or all-wheel drive hybrid vehicles. The model yields similar outputs to a driven vehicle’s normal measured responses.
