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.
