Abstract

This paper mainly introduces the design of intelligent vehicle based on nxp. The intelligent vehicle is powered by nickel-cadmium batteries. MC9S12XS128 MCU is used as the controller. Photoelectric sensors are used to differentiate the track, steering control is carried out by steering gear, speed control is realized by adjusting the speed of DC motor, debugging is carried out by the software of the host computer, and the operation information of the intelligent vehicle is sent to the host computer by wireless data transmission module to monitor the running state in real time. This design completed the design of the system, physical production, system debugging and other work. Through debugging, the design can accurately identify the location of the black line, guide according to the black line, and drive quickly. In the course of driving, the speed and direction are precisely controlled by the PID control algorithm.
