Design and implementation of intelligent track seeking model vehicle based on MC9S12DG128B SCM

This paper studied the control system of a intelligent vehicle which uses the 16-bit Freescale microcontroller MC9S12DG128B SCM as the core control unit, complemented with Direct Current motor, servo motor, Photoelectric sensor, power supply circuit and other circuit. The position signal of the vehicle is collected by the laser sensors arranged regularly at the front of the vehicle body for the purpose of moving controlling decision. Based on the Photoelectric sensor path recognition state analysis and the approach of corner and curved route treatment for the intelligent vehicle, the intelligent vehicle can perform automatic black-line track seeking and complete the vehicle quick and smooth moving along the guide line.
