<p>Provided is a vehicle braking system which includes a master cylinder (M/C) for producing an upstream fluid pressure (Pup) associated with a manipulation of a brake control portion (3); a shut-off valve (MCV 1) or the like which is disposed between the master cylinder (M/C) and a wheel cylinder (4a) or the like; a fluid pressure source (S/C) for producing a downstream fluid pressure (Pdown) between the shut-off valve (MCV 1) and the wheel cylinder (4a) or the like when a command for closing the shut-off valve (MCV 1) has been received; and a control means (11) for setting a target value for the downstream fluid pressure (Pdown) on the basis of the amount of the manipulation and controlling the downstream fluid pressure (Pdown) on the basis of the target value. The control means (11) includes an upstream fluid pressure detecting and estimating means (12) for detecting and estimating the upstream fluid pressure (Pup), and a restricting means (13) for restricting the difference in pressure between the upstream fluid pressure (Pup) and the target value. This allows for providing the vehicle braking system which can prevent an unfamiliar feeling, which the vehicle operator would otherwise experience while manipulating the brake, without an increase in power consumption of the shut-off valve that is disposed between the master cylinder and the wheel cylinder.</p> |
