Abstract Some basic theories about hybrid electric vehicle (HEV) were introduced. The multiobjective optimal model for minimizing the fuel consumption, the sum emission of HC and NOx, and the CO emission was established. A multiobjective evolutionary algorithm for hybrid electrical vehicle based on Pareto optimality (HEVMOEA) was proposed. HEVMOEA uses real coding method to represent gene, and employs ADVISOR to simulate HEV to obtain the value of each objective of candidate solutions, and adopts the Pareto dominance principle to evaluate each solution. A method was put forward to specify the significant digits of variables to guarantee the realizability. A series of simulation results show that HEVMOEA is capable of solving the multiobjective optimization design of HEV, and is promising to provide a set of alternative Pareto optimal solutions characterized with better fuel economy and emission performance for designer.
