The Intelligent Vehicle Navigation System Based on Photoelectric Sensor

Abstract

This paper describes the intelligent vehicle navigation system based on 16 bits MCU MC9S12XS128. The system uses MC9S12XS128 as control core, realizing path recognition through the laser sensor, using PWM signals to control the actuator steering and motor speed, making the intelligent vehicle tracing along the black line of 25mm wide placidly. This technology can be widely used in automatic warehouse, robot vehicle and unmanned factory, etc. In this case, we designed and developed this intelligent vehicle navigation system, among it the PID algorithm is applied to the control structure. And the photoelectric sensing technology is also applied into the system. This system is of important reference significance for the research on unpiloted system.
