The invention relates to the technical field of agricultural machinery, and discloses an agricultural machinery power control method comprising the following steps: estimating the initial demand generation power of the agricultural machinery according to the current complete machine operation condition of the agricultural machinery; on the basis of the power difference between the power generation request power of the agricultural machine at the previous moment and the actual power generation power at the current moment, a compensation correction value associated with the power generation efficiency is obtained; and based on the compensation correction value and a correction coefficient associated with atmospheric pressure, correcting the initial demand generation power to obtain final demand generation power. According to the embodiment of the invention, the influence of the power generation efficiency and the atmospheric pressure on the power generation power following precision is fully considered, and a corresponding compensation correction scheme is provided, so that the actual power generation power infinitely approaches the target power generation power, and the driving and operation requirements of agricultural machinery are met.

    本申请涉及农用机械技术领域,公开了一种农用机械的功率控制方法,包括:根据所述农用机械的当前整机运行工况,估算所述农用机械的初始需求发电功率;基于所述农用机械在上一时刻的发电请求功率和当前时刻的实际发电功率之间的功率差,获取关联于发电效率的补偿修正值;基于所述补偿修正值和关联于大气压力的修正系数,修正所述初始需求发电功率,以得到最终需求发电功率。本申请实施例充分考虑了发电效率和大气压力对发电功率跟随精度的影响,提出了相应的补偿修正方案,使得实际的发电功率无限逼近目标发电功率,满足农用机械的驾驶及运行需求。
