Generally, under a wet railway track condition, the axle adhesion coefficient of a train gradually increases from the head of a rolling stock. The improvement of adhesion characteristics is important in an electric motor coach. In order to suppress the slip/skid phenomenon, we have already proposed an anti-slip/skid re-adhesion control system based on a disturbance observer and sensor-less vector control. Moreover, we have confirmed that this system drives the train with the high adhesion force utilization ratio.This paper discusses the theoretical characteristic of the axle adhesion coefficient distribution of a rolling stock, which is based on the axle adhesion coefficient data of Shinkansen. In order to maintain the desired driving force performance, this paper proposes a new planning torque distribution control based on the axle adhesion coefficient distribution. This paper points out that the proposed method well maintains the desired driving force performance by the numerical simulation results.
