Electropneumatic braking is the most common braking method adopted by most urban rail trains. However, the disadvantages of poor controllability and slow response of air brakes result in inaccurate parking and poor comfort. In addition, there are issues, such as greater losses. The solution to address these issues is to replace existing air braking with electric braking, which is an ideal solution. Based on the development history of full electric braking, this study elaborates on the current situation and the main problems that must be overcome in the application of full electric braking. From the perspectives of high and low speeds, this paper provides a detailed introduction to the difficulties in achieving full electric braking and their corresponding solutions. Each difficulty is analyzed and summarized, and future development directions are discussed.
