主要研究基于磁导技术的飞思卡尔智能车传感器技术及调试方案,经过对磁导车的分析,把磁导车的控制系统分为两个大的子控制系统,它们分别为速度控制系统和方向控制系统。速度控制系统使小车在直道加速行驶在弯道刹车减速以尽量提高行驶速度和避免因速度过快而造成的小车冲出跑道,方向控制系统使小车沿着赛道中间的导线行驶而不偏移。在信号的采集方面我们通过加大前瞻实现小车的预见性,提高小车的转弯的灵活性。为调试出小车的最佳参数,同时还介绍NetUSBDemo软件用于寻找小车最佳参数。通过一系列的调试,最终得出这一套设计调试方案是可行的,能在保证小车稳定性的前提下提高小车速度。 Mainly based on the magnetic guidance technology Freescale smart car sensor technology and debugging programs, after the analysis of the car guide car, the car control system is divided into two large sub-control systems, which are speed control system and Direction control system. The speed control system enables the car to accelerate at the straight road and slow down the brakes at the corners so as to maximize the speed and prevent the car from running out of the runway caused by too fast speed. The direction control system enables the car to run along the wire in the middle of the track without deviation . In the signal acquisition we increase the foresight to achieve the predictability of the car to improve the car’s turning flexibility. To debug the best parameters of the car, but also introduced NetUSBDemo software used to find the best parameters car. Through a series of debugging, it is feasible to conclude that this design and debugging scheme can improve the speed of the car while ensuring the stability of the car.
