The invention discloses an operation machine control method and device and an operation machine. The method comprises the steps that firstly, working condition data including the opening degree of an operation machine handle and the actual current of a traveling pump are obtained; then determining a target current value of the driving pump based on the handle opening degree; and under the first working condition, based on the actual current value and the target current value, the current of the driving pump is gradually adjusted through multiple adjusting periods till the deviation between the current of the driving pump and the target current value is within a preset range, and the current adjusting value of each adjusting period is larger than or equal to the current adjusting value of the last adjusting period. Thus, under the first working condition, such as in the starting process, due to the fact that the adjustment amplitude is small in the early stage of adjustment, starting rushing can be effectively avoided; and the later-stage adjusting amplitude is large, it is guaranteed that the operation machine reaches the needed running speed as soon as possible, and the smoothness of the operation machine and the driving experience of a driver are greatly improved.
本申请公开一种作业机械控制方法、控制装置和作业机械,该方法包括:首先获取包括作业机械手柄开度和行驶泵实际电流的工况数据;然后基于手柄开度,确定行驶泵的目标电流值;在第一工况下,基于实际电流值和目标电流值,通过多个调节周期逐步调节行驶泵的电流,直至行驶泵的电流与目标电流值的偏差处于预设范围内,其中,每个调节周期的电流调节值均大于或等于上个调节周期的电流调节值。如此,在第一工况下,例如起步过程中,因为调节前期,调节幅度较小,可以有效避免起步较冲;而后期调节幅度较大,保证作业机械尽快达到需要的运行速度,大大提高了作业机械的平顺性以及驾驶员的驾驶体验。
