Abstract: This braking control device feeds by pressure a braking fluid from a master cylinder to a wheel cylinder, to generate a braking force in a wheel. The braking control device is provided with an input rod; an output rod; first and second electric motors; and first and second racks forming a differential mechanism. When the outputs of the first and second electric motors are controlled, the operation power of the input rod and the displacement of the output rod are controlled independently of each other. Here, in the second rack, the movement, in a backward direction, in response to decrease of a master cylinder fluid pressure is limited within a range of a predetermined displacement by means of two stoppers.

Abstract: This braking control device comprises a differential mechanism, a first electric motor that generates assisting force in a braking operation member, a second electric motor that adjusts output rod shift of the differential mechanism, and a controller that controls the first and second electric motors. In the controller, the first electric motor is controlled on the basis of an assistance map in which the assisting force is calculated, and the second electric motor is controlled on the basis of a displacement map in which the output rod shift is calculated. When the displacement map is changed, the assistance map is corrected as well.
