基于HCS12 单片机设计一种智能车系统。在该系统中,由红外光电传感器实现路径识别,通过对小车速度的控制,使小车能按照任意给定的黑色引导线平稳地寻迹。实验证明: 系统能很好地满足智能车对路径识别性能和抗干扰能力的要求,速度调节响应时间快,稳态误差小,具有较好的动态性能和良好的鲁棒性。-Based on the HCS12 MCU design an intelligent vehicle system. In this system, the path from the infrared photoelectric sensor to achieve recognition, through the car speed control, so that any given car in accordance with the black guide lines smooth tracing. Results show: The system can be well positioned to meet smart cars on the path to identify the requirements of performance and anti-jamming ability, speed adjustment quick response time, steady-state error is small, has good dynamic performance and good robustness.
