Focusing on the questiong that the information collection instability and poor realtime of the traditional intelligent tracing car, an automatic tracking system based on MK60DN512ZVLQ10 was proposed. The system consisted of the main control module, the sensor module, the motor and the steering gear control module etc. The metal sensors were used to collect complex track information. According to the SPI communication protocol, the collected data were back to the MK60DN512ZVLQ10.Then they were processed in the master chip to determine the body position and track information,to control the direction of the car.As a motor drive module,the BTS7970 could be used to achieve the stability of the motor.For the dualmotor characteristics of the car, the rear wheel respective drive mode was adopted in the design. Two encoders were used to measure speed.Incremental PID algorithm was used to achieve precise closedloop control of the power system,to allow the car to travel quickly along the wire.When the special track information collected,it was displayed through the OLED real-time. Through test, the system can accurately and steadily achieve the complex path tracking function.
