| Abstract: | In this paper an automatic path-finding intelligent vehicle based on laser sensor is designed,with Freescale 16-bit single-chip microcomputer MC9SXS128 as the core controller.An array of laser sensors is used to detect path and calculate lateral deviation between intelligent vehicles and vehicles’ path.A proportional control algorithm is introduced to control the steering engine.Incremental PID closed-loop regulation and control is designed to adjust the rotational speed of the DC motor,thus the intelligent vehicles is able to automatically track back-guide-line and run fast at a steady speed. |
