本设计是基于自动控制的基本原理，以凌阳SPCE061A十六位单片机作为控制核心，通过灰度传感器、角度传感器分别对路面和跷跷板上的引导线以及跷跷板的平衡点进行检测，采用PWM 技术动态控制电机的转速和转向。以此为基本框架，实现了具有一定自适应能力的电动车，能完成题目要求的基本部分和发挥部分，并有创新。 LCD 实时动态显示行驶时间等相关信息以及语音实时播报，使得本设计更趋智能化、人性化。LCD显示路程和语音播报及采用PID算法是本设计的创新点。-The design is based on the basic principles of automatic control in order to Sunplus SPCE061A 16 microcontroller as the control core, through the gray-scale sensors, angle sensors, respectively and the see-saw on the road to guide lines and see-saw balance testing, using PWM Technical dynamic control motor speed and steering. This as a basic framework to achieve with a certain self-adaptive capabilities of electric cars, to complete the subject requirements of the basic part and serve as a partial, and innovative. LCD displays real-time dynamic travel time and other related information as well as real-time broadcast voice, making this design more intelligent and humane. LCD display distance and voice broadcast and the use of PID algorithm is the point of this design innovation.
