The invention discloses a hybrid power bus energy management optimization method based on probability working conditions, and the method comprises the steps: dividing a bus route into a plurality of road sections, and obtaining the vehicle speed data of each road section; calculating a vehicle speed change range at each moment according to the distribution of the vehicle speed at each moment in each road section, and dispersing the vehicle speed change range into a plurality of vehicle speed states; calculating an offline transition probability that the current vehicle speed state is transferred to the next vehicle speed state at each moment; for each road section, a transfer path is constructed from the initial moment, all vehicle speed states in the transfer path meet the condition that the sum of offline transfer probabilities is 1, the sum of all the vehicle speed states is the journey of the road section, and a set of all the vehicle speed states in the transfer path is a probability working condition set; and calculating an optimal equivalent factor under the probability working condition set for the probability working condition set of each road section. The invention also discloses an optimization device for realizing the method. According to the invention, the accuracy of the optimization result is improved.

    本发明公开了一种基于概率工况的混合动力公交能量管理优化方法,包括步骤:将公交路线划分为若干路段,获取每个路段的车速数据;根据每个路段中每一时刻车速的分布计算每一时刻的车速变化范围,将车速变化范围离散为若干车速状态;计算每个时刻的当前车速状态转移至下一车速状态的离线转移概率;针对每个路段,从初始时刻开始构建一个转移路径,使转移路径中的所有车速状态满足离线转移概率之和为1且各车速状态之和为路段的路程,转移路径中各个车速状态的集合即为概率工况集合;对每个路段的概率工况集合计算概率工况集合下的最优等效因子。本发明还公开了实现该方法的优化装置。本发明提升了优化结果的准确度。
