Experimental Research on Dynamic Coordinated Control for PHEV

It is necessary for Parallel Hybrid Electric Vehicle (PHEV) to distribute energy between engine and motor and to control state-switch during work. Aimed at keeping the total torque unchanging under state-switch, the dynamic control strategy/algorithm, which can be expressed as motor torque compensation for engine after torque pre-distribution, engine speed regulation, and dynamic engine torque estimation, is put forward. The dynamic control algorithm is validated by steady and dynamic coordinated state-switch control experiments, respectively, which were achieved by means of building test-bench and getting help from the rapid control prototyping tool dSPACE. The results demonstrate that the dynamic control algorithm can effectively dampen torque fluctuations and ensures power transfer smoothly under various state-switches.
