基于电磁导航的两轮模型车设计

根据全国大学生"恩智浦"杯智能汽车竞赛的比赛要求,设计基于电磁导航的两轮直立模型车方案。主控芯片采用恩智浦公司生产的MKL26Z256VLL4,采用多个电感组成的回路传感器对赛道的磁场信息进行检测。单片机采用互补滤波算法获得模型车倾角信息,通过PID算法控制直流电机驱动模块来控制模型车的平衡及其前进的速度和方向,从而实现智能车稳定、准确、快速地行驶。

For NXP cup national college students intelligent car requirements,a two -wheeled self-balancing model car based on electromagnetic navigation is designed in this paper.The controller is MKL26Z256VLL4 produced by NXP and mul-tiple inductance circuit to detect the path information.The microcomputer uses complementary filter algorithm to obtain the car＇s inclination information,with PID algorithm to control dc motor driver module to control car＇s balance,speed and direc- tion,so that the car can be smooth,accurate and fast driving.
