基于单片机微控制器的无人驾驶小车设计与实现

Design and Implementation of Driverless Cars based on Single-Chip Microcomputer

针对当前无人驾驶车逐步得到广泛应用的需求,同时考虑当前无人驾驶实现中存在的路线规划、障碍规避等较为棘手的问题,文章以STC89C52单片机作为控制核心,设计一辆能够实现黑线寻迹同时兼具避障功能的智能小车。设计采用了RPR220红外寻迹传感器和HC-SR04超声波测距传感器,实现了沿既定路线寻迹和避障功能。最后采用对比实验,验证了方法的合理性和结果正确性,具有较大的应用价值。

In order to meet the demand that driverless cars are gradually being widely used,and considering the thorny problems such as route planning and obstacle avoidance in the realization of driverless cars,this paper takes STC89 C52 single-chip microcomputer as the control core to design an intelligent car which can find black lines and avoid obstacles at the same time.RPR220 infrared tracking sensor and HC-SR04 ultrasonic ranging sensor are used in the design,and the functions of tracking and obstacle avoidance along the given route are realized.Finally,comparative experiments are used to verify the rationality of the method and the correctness of the results,which is of great application value.
