This paper introduces the design of intelligent car control system based on ultrasonic ranging technology for indoor wireless precise positioning.. The system with MSP430F149 microcontroller as the main control chip, using the stepper motor drives the ultrasonic sensor group positioning data collection, through the electronic compass angle detection control car orientation. By nRF905 wireless module duplex radio communication and data exchange is realized. The collected data plotted coordinates display in the control side touch screen, touch screen of trolley position display, and by clicking on the touch screen to achieve control of the car to ifnd corresponding to the position of the function.
