Abstract
A parking brake control apparatus 20 drives an electric motor 43B to advance a piston 39 according to an application request signal from a parking brake switch 19. The parking brake control apparatus 20 includes a running state detection portion that calculates a running state about whether a vehicle is running or stopped based on a wheel signal from a wheel speed sensor 18. When the running state cannot be calculated by the running state detection portion, the parking brake control apparatus 20 controls the electric motor 43B in such a manner that the thrust force of the piston 39 changes at a lower time rate of change than when the running state can be calculated.
