A system of intelligent car is controlled by MSP430F169 microcontroller to realize the car automatic tracking function, inductive sensors are used for data acquisition. The car is made up of coupling isolation motor drive module, geared motor modules, buzzer sound module, LCD module, encoder module, Bluetooth module, battery module. It is a four-wheel driven vehicle, driven by microcontroller which outputs variable pulse signal, and can change steering and speed by DC motor, Microcontroller can continually scan four-channel data outputted by LDC1314 and control the car to complete tracing action. If an obstacle is detected, buzzer module yields voice prompt. It uses timer module fo
