The invention belongs to the technical field of three-axis unmanned vehicles, discloses a three-axis unmanned vehicle hydraulic driving system and a comprehensive energy-saving control strategy thereof, and aims at solving the problems that an existing three-axis unmanned vehicle is complex in oil path structure and poor in posture stability. The device comprises a six-wheel drive hydraulic system; the steering hydraulic system is used for providing independent steering for front wheels and rear wheels of the three-axle unmanned vehicle; the suspension system is at least used for adjusting the suspension height of each wheel, so that the working modes of the suspension system comprise but are not limited to the following modes: a passive suspension mode, a semi-active suspension mode, an active suspension mode, a rigid locking mode and a vehicle height adjusting mode; and the power system is used for providing hydraulic power for actions of the six-wheel drive hydraulic system, the steering hydraulic system and the suspension system. According to the invention, all hydraulic valves can be conveniently integrated into a valve block, so that the oil path structure is reduced, and the requirement of the field unmanned vehicle for executing a specific task can be met.

    本发明属于三轴无人车技术领域,公开了一种三轴无人车液压驱动系统及其综合节能控制策略,为了解决现有三轴无人车油路结构复杂以及姿态稳定性差的问题。本发明包括六轮驱动液压系统;转向液压系统,用于为三轴无人车的前轮和后轮提供独立转向;悬架系统,至少用于对每个车轮的悬架高度进行调节,以使得悬架系统的工作模式包括但不限于如下模式:被动悬架模式、半主动悬架模式、主动悬架模式、刚性闭锁模式和车高调节模式;动力系统,用于为六轮驱动液压系统、转向液压系统和悬架系统的动作提供液压动力。本发明便于将各个液压阀集成阀块,以减少油路结构,能满足对于野外无人车的执行特定任务的需求。
