Abstract:
1. A brake pressure computing apparatus that acquires a target cylinder pressure, the target cylinder pressure being a target value of the pressure inside the brake cylinder of an air brake, the brake pressure computing apparatus comprising: a target cylinder pressure acquirer that acquires the target cylinder pressure on the basis of a required braking force and a target cylinder pressure correction value; a deceleration differential information acquirer that acquires deceleration differential information indicating a deceleration differential, the difference between the target value of the deceleration and the actual value of the deceleration; a pressure differential information acquirer that acquires pressure differential information indicating a cylinder pressure differential, the difference between the target cylinder pressure and the actual value of the pressure inside the brake cylinder; and a target cylinder pressure correction value acquirer that acquires the target cylinder pressure correction value on the basis of the deceleration differential information and the pressure differential information, wherein the target cylinder pressure correction value acquirer sets a sign of the target cylinder pressure correction value to positive or negative on the basis of the deceleration differential information, and sets an absolute value of the target cylinder pressure correction value on the basis of the pressure differential information.
