The invention discloses an agricultural machine leveling method and system. The method comprises the steps that the vehicle body inclination angle of an agricultural machine and the height of each suspension point in three-point suspension are obtained; the leveling threshold angle is used as a target inclination angle, PID control is conducted on the vehicle body inclination angle, and the vehicle body inclination angle after PID control is obtained; determining a displacement adjustment target of each suspension point according to the vehicle body inclination angle after PID control; and performing PID control on the displacement adjustment amount of each suspension point according to the displacement adjustment target of each suspension point. And the leveling effect of the agricultural machinery can be improved.

    本发明公开的一种农业机械调平方法及系统,包括:获取农业机械的车身倾角和三点悬挂中每个悬挂点的高度;以调平阈值角为目标倾角,对车身倾角进行PID控制,获得PID控制后的车身倾角;根据PID控制后的车身倾角,确定每个悬挂点的位移调整目标;根据每个悬挂点的位移调整目标,对每个悬挂点的位移调整量进行PID控制。能够提升农业机械的调平效果。
