The embodiment of the invention provides a vehicle sinking early warning method and device, and engineering machinery, and relates to the technical field of engineering machinery. The vehicle sinkingearly warning method comprises the following steps: acquiring the slip rate of the engineering machinery; acquiring the descending speed of the gravity center of the engineering machinery in the moving process; judging whether the engineering machinery has a vehicle sinking risk or not according to the slip rate and the descending speed; and sending a first alarm signal if the engineering machinery has the vehicle sinking risk. The vehicle sinking early warning method provided by the invention is used for judging whether the engineering machinery has a vehicle sinking risk or not in the working process, and reminding an operator of cautious operation when the vehicle sinking risk exists, so that the vehicle sinking condition is avoided as much as possible, and the maintenance cost of the engineering machinery can be reduced.

    本发明的实施例提供了一种陷车预警方法、装置及工程机械,涉及工程机械技术领域。陷车预警方法包括获取工程机械的滑移率;获取工程机械在运动过程中的重心的下降速度;依据滑移率及下降速度判断工程机械是否有陷车风险;若工程机械有陷车风险则发送第一报警信号。本发明提供的陷车预警方法用于判断工程机械在工作过程中是否有陷车风险,并在存在陷车风险时提醒操驾驶员谨慎操作,尽可能避免出现陷车情况,能够减少工程机械的维修成本。
