The invention relates to the field of hybrid electric vehicles, in particular to a method for limiting the generated power of an extended-range hybrid electric vehicle, which specifically comprises the following steps of: judging whether a mode selected by a driver is an extended-range mode or not; the APU needs to calculate the real real-time power generation power value according to the real-time maximum capacity of the engine and the power generator, and when the power generation capacity of the engine or the power generator is limited by any module due to environmental factors, or the change of the running state of the module, part protection and the like, the APU needs to be combined with the actual part capacity, so that the power generation capacity of the engine or the power generator is limited. And according to a preset map, related correction is added to calculate an actual power generation capacity maximum value, and the problem that the whole vehicle operation safety and the whole vehicle performance can be influenced due to the fact that power limitation is not considered thoroughly or too strictly is solved.

    本发明涉及混合式动力汽车领域,具体地说,本发明涉及一种增程式混合动力电动汽车发电功率限制方法,具体包括以下步骤:判断驾驶员选择的模式是否为增程模式,APU需要根据发动机和发电机的实时最大能力计算出其真实的实时发电功率值,当任一模块因环境因素、或者自身运行状态改变以及出于零部件保护等限制了发动机或者发电机的发电能力时,APU需结合实际的零部件能力,根据预设的map增加相关修正计算出实际的发电能力最大值,解决了功率限制考虑不周或者过于严苛将会影响整车运行安全和整车性能的问题。
