The invention discloses an efficient control method for a full-power fuel cell hybrid power system, and belongs to the technical field of control. Comprising the following steps that current operation parameters of a vehicle and operation parameters of a hydrogen fuel cell are obtained, demand information of the vehicle and operation information of the hydrogen fuel cell are calculated according to the obtained demand information, and then the current operation state of the vehicle and the current working state of the hydrogen fuel cell are judged; under different vehicle running states, according to the vehicle demand information obtained through calculation and the working state of the hydrogen fuel cell, whether the working state of the hydrogen fuel cell is switched or not is judged; and switching the working state of the hydrogen fuel cell according to the judgment result, so that the hydrogen fuel cell works in the most efficient region. According to the invention, the hydrogen fuel cell can be in an optimal working area as far as possible when participating in working, so that the performance of the hydrogen fuel cell is in a relatively high area, and the overall efficiency of the vehicle is effectively improved; the control strategy is simple, and the real-time performance is good.

    本发明公开了一种全功率燃料电池混合动力系统高效控制方法,属于控制技术领域;包括如下步骤:获取车辆目前的运行参数,以及氢燃料电池运行参数,根据所获取的需求信息计算车辆的需求信息以及氢燃料电池运行信息,进而判定车辆当前运行状态与氢燃料电池当前工作状态;在不同的车辆运行状态下,根据计算得到的车辆需求信息以及氢燃料电池工作状态,判定是否切换氢燃料电池的工作状态;根据判定结果,切换氢燃料电池的工作状态,使得氢燃料电池工作在最高效区域。本发明可以使得氢燃料电池在参与工作的情况下尽可能处于最佳工作区,使得氢燃料电池的性能处于较高区域,有效提升车辆整体效率;控制策略简单,实时性好。
