The invention belongs to the technical field of vehicle control, and particularly relates to a recommended vehicle speed calculation method and device, a medium and an ECU. In the linearly changing vehicle speed, a plurality of points are selected as references, the energy consumption of each reference point is calculated, the reference point with the lowest energy consumption and the highest efficiency can be compared to serve as the recommended vehicle speed, and the working efficiency of the power assembly can be remarkably improved by combining reasonable economical vehicle speed suggestions proposed for a driver within the allowable vehicle speed range. According to the method, the energy consumption matrix is processed in a rolling mode, after new sample data enters, original data bits are sequentially moved backwards, the last bit of sample data is directly abandoned, the sample storage number can be kept, and the data storage pressure is reduced; the energy consumption evaluation index is calculated by adopting sample data which is similar to an attention mechanism and is influenced by recent time, so that the influence of other factors such as different road conditions and different tire pressures on the energy consumption evaluation index can be reduced.
本发明属于车辆控制技术领域,特别涉及一种推荐车速计算方法、装置、介质及ECU。在线性变化的车速中,选择若干点作为参考,分别计算每个参考点的能耗,即可比较出能耗最低、效率最高的参考点作为推荐车速,结合允许车速范围内对驾驶员提出合理的经济性车速建议,可显著提高动力总成的工作效率。本发明采用滚动的方式处理能耗矩阵,新的样本数据进入后原有数据位次依次向后挪动,最后一位样本数据直接舍弃,可以保持样本存储数量,减小数据存储压力;计算能耗评价指标采用类似于注意力机制,受近期时间影响的样本数据对能耗评价指标影响更大,因此可以淡化能耗评价指标受到不同路况、不同胎压等其它因素影响。
