The proposal of re-adhesion control method with the advantage of individual control system

摘要

The Chiyoda line train of Tokyo Metro had the problem of insufficient acceleration while running in rainy condition. We investigated the problem of conventional wheel slip control method and found the solution. We tested the new method in the mainline test with actual train and concluded that the new method works well with better torque performance. In this paper, we report the proposed new control method and the test result.
