摘　　要：针对功率车在使用过程中骑行体验感较差的问题,提出了一种具有人机交互功能的功率车训练系统。该系统的下位机由功率车、霍尔传感器、单片机和伺服电机等模块组成,功率车的阻力通过设计的新型磁阻装置进行无级连续调节。基于贝塞尔曲线对上位机的骑行路径进行优化,结合实时插值、等距插值和非等距插值算法,提升了场景跟踪效果。实验结果表明,基于贝塞尔曲线的实时插值算法生成的路径能够满足体感一致性,确保人机交互过程中场景的流畅性与稳定性。Aiming at the problem of poor riding experience in the use of power vehicle,a power vehicle training system with human-computer interaction function was proposed.The lower computer of this system was composed of power vehicle,Hall sensor,single chip microcomputer,servo motor and other modules.The resistance of power vehicle could be continuously adjusted by the newly designed magnetic resistance device.The riding path of the host computer was optimized by using Bezier curve,and the scene tracking effect was improved by combining with real-time interpolation,equidistant interpolation and non-equidistant interpolation algorithms.The experimental results show that the path generated by the real-time interpolation algorithm based on Bezier curve can satisfy the somatosensory consistency and warrant the fluency and stability of riding scene during the process of human-computer interaction.
