SOLUTION: An actuator is installed between a vehicle body of a vehicle on which a bolsterless bogie is mounted and a truck frame. A sensor is installed on at least any one of the vehicle body, bogie and wheel shaft. One or plural parameters having correlation with steady lateral pressure are calculated on the basis of a state amount acquired in travel, by the sensor, and a thrust command value to the actuator is determined by applying a prescribed transmission function to the calculation value. At the same time, one or plural parameters having correlation with variation lateral pressure are calculated, and a thrust command value to the actuator is determined by applying a prescribed transmission function to the calculation value. Then, the two thrust command values are combined for determining thrust generated on the actuator.EFFECT: As a result, maximum lateral pressure generated in travel can be efficiently reduced, so that travel maximum speed can be improved.SELECTED DRAWING: Figure 1

    【解決手段】例えばボルスタレス台車を搭載した車両の車体と台車枠間にアクチュエータを設置する。車体・台車・輪軸の少なくとも何れか一つにセンサーを設置する。センサーを用いて走行中に取得した状態量に基づき、定常横圧と相関を有する一つ又は複数のパラメータを演算して、当該演算値に所定の伝達関数を適用してアクチュエータへの推力指令値を決定する。同時に、変動横圧と相関を有する一つ又は複数のパラメータを演算して、当該演算値に所定の伝達関数を適用してアクチュエータへの推力指令値を決定する。その後、これら2つの推力指令値を合成してアクチュエータに発生させる推力を決定する。【効果】走行中に発生する最大横圧を効果的に低減できるので、走行最高速度の向上が可能となる。【選択図】図1
