| description | PROBLEM TO BE SOLVED: To improve the operation feeling of a brake pedal by restricting a sudden change of the reaction force to the operation of the brake pedal in an electric booster.SOLUTION: A master pressure control device 3 controls an electric motor 20 based on the amount of movement of an input rod 7, and a primary piston 40 is propelled through a ball and screw mechanism 25 so as to generate the brake hydraulic pressure in a master cylinder 9. The brake hydraulic pressure of the master cylinder 9 is fed back to the brake pedal 100 by an input piston 16 through the input rod 7. When the amount of movement of the input rod 7 achieved a predetermined threshold value, a ratio of the amount of movement of the primary piston 40 to the amount of movement of the input rod 7 is reduced. Fluctuations of the pedal effort when the only input piston 16 moves forward with the pedal effort by a driver after the electric motor 20 achieved a full-load condition and the primary piston 40 stopped is thereby reduced, and the operation feeling of the brake pedal 100 is improved. |
