1 飞思卡尔智能车介绍

全国大学生飞思卡尔智能车竞赛是半导体公司飞思卡尔举办的比赛。

恩智浦公司收购了飞思卡尔公司,所以第十一届比赛更名为恩智浦杯智能车竞赛。

飞思卡尔智能车有多种,包括摄像头组、光电组、电磁组等等。

这个仓库中的程序是光电组智能车的程序。

飞思卡尔智能车竞赛,光电组,采用两侧黑线,中间白线的跑道

光电组智能车使用光电传感器CCD,检测跑道两侧的黑线,并使用特定算法处理,得到跑道的数据。

智能车需要使用舵机转向,来适应跑道,防止冲出跑道,使用改进的PID控制算法,来控制舵机。

智能车的速度也需要精确的控制。电机的转速,会受到电池电压,阻力等因素的影响,因此需要自动控制算法,电机的自动控制算法使用位置式PID。
