Abstract
In recent years, electric vehicles by the governments and major car companies attach great importance, to the same time, with the electronic car, intelligent degree is getting higher and higher, the car needs to meet the more energy efficient, cleaner, more secure travel requirements, Electrical Parking Brake (EPB) is one of the active safety technologies of automobile. It is a research hotspot of modern automobile active safety technology. It is an important technology to realize modern automobile energy saving, environmental protection and safety. In the ABS, ESP and other technologies have been born, the major car companies began to develop this new type of electric control brake technology, a variety of high-tech applications to give electric vehicles a better energy saving effect. Its structure compared with the traditional mechanical parking system, easy to arrange, simple operation, small footprint, high efficiency.
In this paper, the research and design of electric parking system for electric vehicle are carried out. Firstly, the research status of parking system at home and abroad is analyzed, and the shortcomings of the current parking system are discussed. Then, according to the system requirements, The design and model analysis of the overall structure of the electronic parking brake system, the ADAMS modeling and simulation, and the calculation of the core components of the relevant implementing agencies are carried out, and the control of the vehicle electronic parking system is carried out. Strategy has been carried out to achieve the corresponding functions in different conditions, including conventional control strategies and intelligent control strategies and extended functions.
The simulation results show that the design of the electronic parking brake system meets the design requirements, can achieve the expected function, and achieved satisfactory results.
Keywords:electric vehicles ;Electrical Parking Brake (EPB);ADAMS; control Strategy
