The improvement of adhesion characteristics is important in electric commuter train. The electric commuter train has both a slip phenomenon and a slide phenomenon. Slip-and-slide phenomena degrade the comfortable riding performance of electric commuter train. We have already proposed an antislip/ antislide readhesion control system based on disturbance observer and sensorless vector control. The effectiveness of the proposed method has been confirmed by the experiment and the numerical simulation using the tested bogie system of electric commuter train. Then, we apply the proposed method to the actual electric commuter train of series 205-5000 of the East Japan Railway Company. In the experimental results of series 205-5000, this paper demonstrates that the proposed antislip/slide readhesion control system has the desired driving wheel torque response. Moreover, this paper discusses the evaluation method of readhesion control test results.
