The invention discloses an anti-overturning method for an electric forklift. The anti-overturning method comprises the steps that the cargo weight, the cargo lifting height, the transverse inclination angle, the longitudinal inclination angle and the cargo fork inclination angle of the electric forklift are obtained; the combined gravity center of the electric forklift and the goods is obtained according to the weight of the goods, the lifting height of the goods and the inclination angle of the fork; constructing a supporting plane; judging whether the electric forklift meets a supporting plane stability condition or not according to the transverse inclination angle, the longitudinal inclination angle, the gravity center and the supporting plane; if the pallet fork of the electric forklift faces the downhill direction and the longitudinal dip angle exceeds an alarm threshold value, the risk position 1 is set, and anti-overturning control is started; and if the electric forklift does not meet the supporting plane stability condition, the risk position 2 is started, and anti-overturning control is started. According to the invention, measures can be actively taken to prevent overturning.
本发明公开了一种电动叉车防倾覆方法包括:获取电动叉车的货物重量、货物起升高度、横向倾角、纵向倾角以及货叉倾斜角度;根据货物重量、货物起升高度、货叉倾斜角度、得到电动叉车和货物的联合重心;构建支撑平面;根据横向倾角、纵向倾角联合重心以及支撑平面判断电动叉车是否满足支撑平面稳定性条件;若电动叉车的货叉朝向下坡方向,且纵向倾角超过告警阈值,则将风险位置1,启动防倾覆控制;若电动叉车不满足支撑平面稳定性条件则将风险位置2,启动防倾覆控制。本发明能够主动采取措施防止倾覆发生。
