The invention discloses an autonomous driving method of an extravehicular manned maneuvering device, which comprises the following steps: S1, determining a rendezvous target and rendezvous time, calculating a required speed increment by taking time as a constraint, and further driving a thruster of the extravehicular manned maneuvering device to move; s2, after the manned maneuvering device outside the driving cabin gets close to the rendezvous target, the manned maneuvering device slows down and is relatively static; and S3, approaching the rendezvous target at a low speed until reaching the rendezvous target. The system has an automatic driving function, so that astronauts can conveniently go to a predetermined area; in the operation process of the astronaut, the outboard manned maneuvering device is automatically kept, the two hands of the astronaut can be liberated, and meanwhile a stable posture is provided; the outboard manned maneuvering device has the anti-collision function and the propellant insufficiency warning function, meanwhile, the outboard manned maneuvering device can automatically return under the condition that the astronaut is coma or loses the operation function, and the safety of outboard activities of the astronaut is improved.

    本发明公开了一种舱外载人机动装置的自主驾驶方法,包括如下步骤:S1:确定交会目标和交会时间,以时间为约束计算所需速度增量,进而驱动舱外载人机动装置的推力器实现移动;S2:待所述驱动舱外载人机动装置靠近所述交会目标后减速并相对静止;S3:再低速接近所述交会目标,直至到达所述交会目标。本发明具备自动驾驶功能,方便宇航员到预定区域;在宇航员操作过程中,舱外载人机动装置自动保持,可解放宇航员双手,同时提供稳定的姿态;具备防碰撞、推进剂不足告警功能,同时可在宇航员发生昏迷或丧失操作功能条件下,舱外载人机动装置自动返回,增加宇航员出舱活动的安全性。
