These demands not only include acceleration, economy and safety, but also include many elements such as intelligence and humanity. For this purpose, the electronic parking brake system replaces the original mechanical structure to make the parking control more convenient and safe, and can work together with other electronic control systems on the vehicle. In this paper, the electronic parking brake system is discussed and studied, which provides a certain method, theoretical basis and design requirements for the development of the electronic parking brake system. This paper first introduces the research status of the electronic parking brake system at home and abroad, expounds the basic principle of the electronic parking brake system, designs the structure of the electronic parking brake system, analyzes the national standard of the parking brake system and the specific requirements of the electronic parking brake system, carries out the overall scheme design and feasibility analysis, and then designs the electronic parking brake system from the aspects of hardware and software Finally, the mathematical model of the electric motor and screw drive mechanism in the electronic parking brake system is established, and the simulation platform is built in MATLAB for simulation analysis.
