Abstract
The paper introduced intelligent vehicle autonomous tracing the design and study of the infrared reflecting photoelectric sensor moduleas a path to the realization of automatic tracing of hardware and software。 This system design method to design the topic request, for the purpose of 89C51 microcontroller as control core, using infrared photoelectricity sensors to collect information, the automatic control of electric car obstacle-avoidance, speed, the system when the circuit is simple in structure, reliable performance. The test results, this paper introduces the hardware design method of system analysis and test results. Our main problem is: car intelligent control hardware circuit design, Cars run route and state control of the software design, Infrared sensor design of obstacle avoidance。 I'm responsible for using infrared sensor design of obstacle avoidance。The adoption of technique as:Reduce the speed by program the engine;Efficient application of the sensor;The adoption of the new display chip.
