On the basis of combined fuzzy logic scheme and PID strategy. The anticipative tor ue w as distributed betw een the internal combustion engine and electric w ith the fuzzy- logic controller and the PID motor charge sustaining strategy w as used to ensure a better balance of battery. s charging during the w hole driving cycle. Computer simulation w as car- ried out to evaluate the energy management system proposed. It w as found that significant improvement on fuel economy and vehicle. s pow er performance could be achieved w ith remarkable emission reduction.
