The invention discloses a working condition information acquisition method for vehicle global energy management control. According to the uncertainty of information which can be known in advance, vehicle speed, slip rate and road gradient information can be obtained from three levels. When the running vehicle speed and road altitude of a vehicle under the whole working condition can be obtained, information of each working condition is obtained according to collected data; when the rule followed by the working condition information of the vehicle running under the whole working condition can be obtained, if a certain exact distribution function can be used for expressing the distribution rule, the information of each working condition is obtained according to the function, otherwise, a state transition probability matrix is constructed based on historical running data to obtain the information of each working condition; and when the constraint conditions applied to the running workingcondition information of the vehicle under the whole working condition can be obtained, the outer contour line of the vehicle is obtained according to the constraint conditions, and the information ofeach working condition is obtained based on the entropy maximum principle. Comprehensive and accurate working condition information can be provided for vehicle global energy management, and the possibility of globally optimizing real vehicle application is improved.

    本发明公开一种用于车辆全局能量管理控制的工况信息获取方法,根据可预先了解信息的不确定性,从三个层次实现车速、滑移率、道路坡度信息的获取:当车辆在整个工况下的行驶车速和道路海拔可获取时,根据采集的数据获取各工况信息;当车辆在整个工况下行驶的工况信息所遵循的规律可获取时,若能用某一确切的分布函数以表述其分布规律,根据此函数获取各工况信息,反之,基于历史行驶数据构建状态转移概率矩阵,获取各工况信息;当车辆在整个工况下针对行驶的工况信息所施加的约束条件可获取时,根据所述约束条件获取其外轮廓线,基于熵最大原理获取各工况信息。能够为车辆全局能量管理提供全面、准确的工况信息,提高全局优化实车应用的可能性。
