置が得られる効果を有している。As described above, according to the present invention, the brake cylinder pressure rapid release device operated by the brake rapid release command is provided to rapidly attenuate the brake cylinder pressure of the fluid mobile vehicle. Braking can be released or suppressed, thus increasing the brake release speed of a fluid mobile vehicle where the braking force is released slowly to the same or close to the brake release speed of an electric brake vehicle where the braking force is released rapidly. As a result, even when an electric brake vehicle and a fluid mobile vehicle are connected, there is no impulse between the two vehicles when the brakes are released, improving riding comfort and preventing passengers from falling over. This has the effect that a braking device can provide.
