Abstract
In a braking-force generator: a master cylinder generates first braking force corresponding to an operational input through a manipulator; a hydraulic-pressure generator connected to the master cylinder through a shutoff valve generates second braking force corresponding to the operational input through the manipulator when the shutoff valve is closed; an abnormality detector repeatedly determines whether or not an operational state of the hydraulic-pressure generator is abnormal; and a controller prohibits generation of the second braking force, opens the shutoff valve, and transmits the first braking force to the hydraulic-pressure generator, when the operational state is abnormal. In the case where the abnormality detector determines that the operational state changes from an abnormal state to a normal state while manipulation with the manipulator is being performed, the controller keeps prohibition of the generation of the second braking force and keeps the shutoff valve open until the manipulation is terminated.
