The invention discloses a vehicle body posture semi-active leveling control method and system and an engineering vehicle, and belongs to the technical field of engineering machine.The manual control method comprises the steps that the vehicle state is adjusted to meet the selected posture adjustment requirement, and the vehicle body posture is adjusted according to preset vehicle body displacement information in the current posture adjustment mode; the active control method comprises the steps that when a vehicle is located on a horizontal road, the vehicle body posture is adjusted according to preset vehicle body displacement information in a neutral position returning mode, when the vehicle is located on a slope, the current vehicle state is adjusted to meet the leveling requirement, an adaptive vehicle body displacement action is executed according to the road environment where the vehicle is located to level the vehicle body, and meanwhile, the vehicle body posture is adjusted. And judging whether the vehicle is in a horizontal state or not, if yes, entering a judgment cycle, and/or if not, adjusting the current vehicle body posture according to preset vehicle body displacement information in the current posture adjustment mode, so that the engineering vehicle realizes automatic adjustment without site limitation in the driving process.

    本发明公开了一种车身姿态半主动调平控制方法、系统以及工程车辆,属于工程机械技术领域,其中,手动控制方法包括:将车辆状态调整至满足选择的姿态调整要求,根据当前姿态调整模式下预设的车身变位信息对车身姿态进行调整;主动控制方法包括:当车辆处于水平道路时,根据回中位模式下预设的车身变位信息对车身姿态进行调整,当车辆处于斜坡时,调整当前车辆状态至满足调平要求,根据车辆所处道路环境执行适应的车身变位动作对车身进行调平,同时,判断车辆是否处于水平状态,若是,进入判断循环,和/或,若否,根据当前姿态调整模式下预设的车身变位信息对当前车身姿态进行调整,使工程车辆在行驶过程中实现了不限场地的自动调整。
