Abstract With the rapid development of China in the field of automatic control technology, automation technology has been popularized and applied to various fields and industries in the country。 Intelligent car is also one of the important achievements in the development of automatic control technology。 In the increasingly serious air pollution, energy shortages, traffic jams of the environmental problems, people more and more need of lightweight, small, energy-saving means of transport。 Therefore, the research of the two wheeled balancing car has become a topic of concern。
In this paper, the STM32 is introduced to the development platform of two wheeled balancing car, and successfully developed a car model。 Firstly, the overall design scheme and the basic working principle of the vehicle system are studied, and the key equipment is selected, and the main hardware model is determined。 Then, the control flow of the software system of the two wheel balancing car is studied deeply, and the double closed-loop control of DC motor speed is adopted to realize the normal operation of the car。 Then in the debugging process, respectively, the car system virtual decomposition of the three links (vertical ring, speed ring, the steering ring) were carried out the parameters of the whole set and the actual state of the test, the results are good。 Finally, the prototype of the two wheeled balancing car is debugged, and the running test of the obstacle and the obstacle are carried out。 The experimental results show that the operation of the two wheel balancing trolley is stable, and the basic operation function can be achieved。
