摘要

Based on the hierarchical structure, a hybrid control strategy is designed for PSHEV. The strategy divides the hybrid control logic into decision-making layer, the middle layer and the servo layer. The decision-making layer determines the total request power and the system control mode, the middle layer distributes the power to components and determines the static control objectives, and the servo layer determines the transient control objectives according to the requirement of control quality. The ECU software and hardware of the hybrid control unit is developed and the typical situation tests are carried out by the Hardware-In-the-Loop (HIL) simulation platform. The results indicate that the designed hybrid control strategy for PSHEV can realize the energy management and control well, and the fuel economy is increased by the optimal configuration of engine working state. The hierarchical structure designed method for control strategy makes the control logic much more concise and legible, and gives attention to the optimal configuration of the power and the requirement of control quality in transient process meanwhile.
