Abstract

The invention discloses a lunar surface virtual driving somatosensory feedback method based on attitude tracking. In combination with a lunar surface working environment, a classic washout algorithm is optimized, a tilt coordination channel is added to simulate longitudinal and transverse linear accelerations, and an angular velocity amplitude limiting link is improved, so that a human body is difficult to perceive pose changes caused by tilt coordination. Washout operation is carried out based on the model, the motion displacement of the six-degree-of-freedom platform is calculated, driving signals of all rod pieces are obtained through conversion, and the motion platform is controlled to achieve posture following. According to the method, the vehicle motion simulation in the lunar surface environment can be realized, so that a driver has a vivid concept on the motion condition of the vehicle during actual driving in the ground training environment. The somatosensory feedback technology is optimized, the fidelity of motion simulation is improved, and the driving training effect is improved.

Description

technical field [0001] The invention belongs to the field of somatosensory feedback, and in particular relates to a somatosensory feedback method for virtual driving on a lunar surface based on posture tracking. Background technique [0002] In order to create a realistic working environment on the lunar surface, the common lunar surface driving simulation system simulates the movement state of the lunar rover by controlling the six-degree-of-freedom motion platform, and transmits the motion perception to the trainers in the simulated cockpit. [0003] The main mechanism that affects the authenticity of motion simulation is the six-degree-of-freedom motion platform. Due to the limitation of the mechanical structure, the translation range of the platform is limited. Therefore, in the process of simulating the actual movement of the vehicle, it is difficult for the platform to track the six-degree-of-freedom attitude of the vehicle, and corresponding processing is required. ...
