At present, the enterprise production technology constantly improving, the deepening environment to automation technology requirement, intelligent vehicle, and on the basis of intelligent vehicle developed products have become automated logistics transportation, flexible production organization system of key equipment. Many countries in the world are actively in research and development of intelligent vehicle design. The purpose is to apply artificial intelligence technology in complex environment, complete robot autonomous reasoning, planning and control system. From then on, the mobile robot from scratch, increasing number of intelligent vehicle as an important branch of mobile robot has been more and more attention. Smart car is a collection of environment awareness, planning decision and automatic drive, and other functions in an integrated system, the use of concentrated in the automatic control, pattern recognition, sensor technology, automotive electronics, electrical, computer, machinery, and many other disciplines, is a typical combination of new and high technology, has the important value of military and civilian. This article tells the story of the FREESCALE MC9S12XS128 as microprocessor designed a can listen to the voice of the smart car.
This article mainly USES the LD3320 as speech recognition, through the writing of the program, make it can output signal, and then to MC9S12XS128 microprocessor processing the received data, and then make the car we want to achieve.
