Abstract:
1. A braking-force generator comprising: a master cylinder which generates first braking force corresponding to an operational input through a manipulator; a hydraulic-pressure generating means which is connected to the master cylinder through a shutoff valve in such a manner that the hydraulic-pressure generating means can be shut off from the master cylinder, and generates second braking force corresponding to the operational input through the manipulator when the hydraulic-pressure generating means is shut off from the master cylinder; an abnormality determination means which repeatedly determines whether or not an operational state of the hydraulic-pressure generating means is abnormal; and a control means which opens the shutoff valve and controls to prohibit generation of the second braking force by the hydraulic-pressure generating means so as to transmit to the hydraulic-pressure generating means the first braking force generated by the master cylinder, when the operational state is determined to be abnormal; wherein in the case where the abnormality determination means determines that the operational state changes from an abnormal state to a normal state while manipulation with the manipulator is being performed, the control means keeps to control the shut off valve open and controls to keep prohibition of generation of the second braking force by the hydraulic-pressure generating means until the manipulation is terminated.
