Parameter Match and Simulation Analysis of a Parallel Hybrid Electric Vehicle

Design and simulation method for parallel hybrid powertrain used in 4WD vehicle was proposed. Computation models of main components in hybrid powertrain were established and simulated with the help of the modified ADVISOR, in which control strategy was improved to enhance regenerative efficiency. Simulation results were verified by field experiment results of the developed hybrid electric off-road vehicle. Experiment and simulation results show that the developed vehicle is practicable and match of different power sources is vey important to hybrid powertrain.
