Abstract

Provided is a slip / skid discrimination device (13) comprising a shaft speed determination unit (51), a reference shaft speed determination unit (52), and a discrimination unit (53). The shaft speed determination unit (51) determines a shaft speed for each axle, the speed changing in response to the rotation speed of a wheel. The reference shaft speed determination unit (52) determines a reference shaft speed in a railroad vehicle on the basis of the shaft speed and a physical quantity which changes during travel of the vehicle. The discrimination unit (53) discriminates absence and presence of slip or skid of the wheel from each other on the basis of comparison between the shaft speed and the reference shaft speed.
