<P>PROBLEM TO BE SOLVED: To suppress a load imparted to a fluid passage around a wheel cylinder. <P>SOLUTION: A braking control device 10 assists a step-on operation force of a brake pedal 12 by utilizing accumulator pressure. When the brake pedal 12 is stepped on, pressure in a booster chamber is boosted by the introduction of an operating fluid from an accumulator 48. A pressure-increasing valve 50RL for a left rear wheel and a pressure-increasing valve 50RR for a right rear wheel are interposed between the booster chamber and a wheel cylinder. A regulator pressure sensor 62 detects fluid pressure in the booster chamber. A wheel-cylinder pressure control part closes the pressure-increasing valve 50RL for the left rear wheel and the pressure-increasing valve 50RR for the right rear wheel when the fluid pressure in the booster chamber is boosted to reference fluid-pressure. <P>COPYRIGHT: (C)2010,JPO&INPIT |
