A comparative study of fuzzy logic-based control strategies for a parallel mild Hybrid Electric Vehicle

In this paper, power distribution control strategies are applied to a mid-size parallel mild Hybrid Electric Vehicle (HEV) and the control performances are compared. The structure and the operation principle of a HEV are introduced, and it is shown that a conventional fuzzy logic-based power control strategy can be modified for fuel consumption optimization. Through simulation results, the fuel-optimized fuzzy logic-based power control method is shown to give better control performance than other methods especially for the urban driving conditions.
