An actuator is installed between a vehicle body of a vehicle mounted with a bolsterless carriage, for example, and a carriage frame. A sensor is installed on at least one of the vehicle body, the carriage, and a wheelset. Based on a state quantity acquired by the sensor during travel, one or a plurality of parameters having a correlation with steady lateral pressure is computed, and a thrust command value for the actuator is determined by applying a predetermined transmission function to the computed value. At the same time, one or a plurality of parameters having a correlation with a variable lateral pressure is computed, and a thrust command value for the actuator is determined by applying a predetermined transmission function to the computed value. Thereafter, the two thrust command values are combined to determine a thrust that the actuator is caused to generate. Because the maximum lateral pressure generated during travel can be effectively decreased, an increase in the maximum travel speed can be achieved. |
