The embodiment of the invention provides a method for detecting axle load, a controller and engineering machinery. The method comprises the following steps: acquiring stress information of each suspension bridge; determining the pressure axle load of each suspension bridge according to the stress information; obtaining the whole vehicle horizontal state information of the engineering machinery, and determining a first inclination angle and a second inclination angle according to the horizontal state information; determining an inclination axle load correction coefficient according to the first inclination angle and the second inclination angle; determining a suspension axle load correction coefficient of each suspension bridge according to the suspension oil cylinder position of each suspension bridge; and determining the axle load corresponding to each suspension bridge according to the pressure axle load and the inclined axle load correction coefficient. According to the scheme, the correction coefficient is determined, and the axle loads of the whole vehicle and each suspension bridge are detected in real time through the correction coefficient, so that the axle loads can be detected in real time on a flat road surface or a fluctuating road surface or a ramp road surface, the axle load detection data can be determined more accurately, and the method is more applicable to all road conditions.
本申请实施例提供一种用于检测轴荷的方法、控制器及工程机械。方法包括:获取每个悬架桥的受力信息;根据受力信息确定每个悬架桥的压力轴荷;获取工程机械的整车水平状态信息,并根据水平状态信息确定第一倾斜角度和第二倾斜角度;根据第一倾斜角度和第二倾斜角度确定倾斜轴荷校正系数;根据每个悬架桥的悬挂油缸位置确定每个悬架桥的悬挂轴荷校正系数;根据压力轴荷和倾斜轴荷校正系数确定每个悬架桥对应的轴荷。上述方案通过确定校正系数,并通过校正系数实时检测整车以及各个悬架桥的轴荷,从而在平整路面或起伏路面或坡道路面也能够对轴荷进行实时检测,并能更准确地确定轴荷检测数据,更具有全路况的适用性。
