| ABSTRACT |
|
In this paper, we propose a new control logic for hybrid vehicle control technology using predictable real road information. The newly proposed control logic is implemented in real time by applying the shifting map of the engine and transmission applied to the hybrid vehicle and the mode conversion map extracted from various driving modes. The proposed control logic has the advantage of minimizing the loss compared to the theoretical maximum fuel consumption implemented in the backward simulation and achieving more stable shifting and mode conversion. As a result of applying the proposed control algorithm to the omnidirectional simulation, the result showed better fuel efficiency improvement than the existing rule base control method. The newly proposed control algorithm can be used as a hybrid control algorithm that can solve the computation time problems required for the optimization process through the conventional reverse simulation and can perform stable shift and mode conversion in real time. |
