本文通过数字电路中集成芯片的综合应用，设计出了满足要求的小汽车遥控电路。在电路中，实现了小汽车的前进、后退、左转、右转四个单独功能的控制，在此基础上，实现了三种路径（前后、人字、8字）行驶的自动驾驶控制，并且，设计了速度适中，两档可控的转换电路，最后，电路中实现了暂停功能的控制。-In this paper, an integrated circuit chip digital integrated application designed to meet the requirements of car control circuit. In the circuit to achieve the car' s forward, backward, turn left, turn right to control four separate functions, in this based on the realization of three paths (before and after the word, 8 word) driving the automatic driving, Also, the design speed is moderate, two tranches of the conversion control circuit, and finally, the circuit is implemented in the control pause.
