According to the smart car need charging by the solar panel as quickly as possible, through research and analysis of the direct solar radiation, scattered radiation and ground reflected radiation changes, combining the rotating system and the physical structure of the smart car, established the model of smart car instantaneous power. Based on the model, we propose a single-axis tracking program to track the sun shortest interval, so that the total generating capacity of solar panels is the largest. Through experiments by using MATLAB proved that the tracking program to track solar with shorest interval is more better than others, it gained more power, shorten the charging time and has achieved the anticipated effect.%针对于智能车完全需要由太阳能电池板尽可能快补充电能的需求,通过对太阳直接辐射、散射辐射和地面反射辐射变化量的研究分析,结合智能车自身的转动系统和实体结构,建立了智能车的瞬时发电模型.并据此模型提出一种最短跟踪间隔的太阳单轴跟踪方案,使得太阳能电池板总发电量最大.通过MATLAB仿真实验,证明了最短跟踪间隔的太阳跟踪方案一天的发电量要高于其他跟踪间隔的发电量,缩短了智能车充电时间,达到了预期效果.
