人机结合型节能助力车研究
|
摘要
分析了目前市场上常见的推车、拉车、拖车的驱动方式,设计提出了一种区别于传统的纯人力型车或纯动力型车的人机结合型节能助力车。该助力车以飞思卡尔单片机(汽车级别)为核心处理器,通过实时检测操作者施力信号大小,由有刷直流电动机适当提供助力辅助操作者工作。由于只是助力辅助,可有效节省蓄电池的电能消耗,减少蓄电池的充电次数,一方面有利于节能,另一方面有利于延长蓄电池的使用寿命。对该助力车控制系统放电情况进行测试分析,结果证明,数据曲线较其他助力车数据曲线光滑,即其助力效果更佳,因此所研究的人机结合型节能助力车符合设计要求。
This paper analyzes the common driving modes of trolleys, carts and trailers in the market at present, and proposes a man-machine integrated energy-saving auxiliary vehicle which is different from the traditional pure manpower vehicle or pure power vehicle. With Freescale MCU as the core processor, the auxiliary electric vehicle can detect the magnitude of the operator′s power signal in real time and properly provide assistance to the operator through the brush dc motor. As it is only the power assist, it can save power consumption of the battery effectively and reduce the number of charging times of the battery. On one hand, it is conducive to energy saving. On the other hand, it is conducive to extend the service life of the battery. The discharge of the control system of this auxiliary electric vehicle is tested and analyzed. The results show that the data curve is smoother than that of other auxiliary electric vehicles, that is, its power effect is better. Therefore, the research of man-machine integrated energy-saving auxiliary vehicle meets the design requirements.
