Research on a Novel Type of Hybrid Propulsion System and Control Strategy for Tracked Vehicle

In order to search after a new way for the propulsion system of the tracked vehicle, a novel type of power-split hybrid propulsion system is proposed. Its configuration and working mode are set down, and then its power distribution and control strategy are also analyzed. A collaborative simulation model is built to simulate the system, based on interface technology between AMESim Software and MATLAB/Simulink Software. The mechanical assembly is modeled by AMESim; meanwhile the control system model is built by MATLAB/Simulink. Finally, the simulation result shows that the performances of the new hybrid propulsion system are superior in many respects to the comprehensive hydraulic-mechanical gearbox and especially its acceleration time is only 7.9s from 0 to 32 km/h.
