Abstract: A vehicle brake controller is capable of executing limit control when a driver is performing a brake pedal operation during turning of a vehicle, to limit an increase in a braking force applied to an inner wheel that is a wheel positioned on the inner side of the turn. The vehicle brake controller is configured to start the limit control when a wheel state value that becomes greater as deceleration of the inner wheel becomes greater exceeds a start determination value that is set to a value greater than zero.

Abstract: A braking control device for a vehicle executes braking force distribution (BFD) biased to front wheel in a manner compatible with Anti-skid control. In BFD control, braking force on rear wheels is held at a holding braking force and braking force on the front wheels is incremented beyond braking force requested by a braking action of a driver. After the starting of BFD control, further increase in the braking action is reflected in the front wheel braking force. Upon starting anti-skid control for either of the wheels during the execution of BFD control, an increment of the front wheel braking forces to be requested by BFD control is gradually decreased. Simultaneously, the holding of the rear braking force is released so as to compensate for the shortage of braking force on the front wheel. The gradual decrease of the braking force increment prevents a conflict of BFD and Anti-skid control.

Abstract: A master cylinder device connected with a brake booster device of an input rod pulling type is disclosed. In the brake booster device, the interior of a brake booster is partitioned by a diaphragm with a piston secured thereto, into a constant pressure chamber and a variable pressure chamber. The piston incorporates therein a valve mechanism operated by a brake pedal for making the variable pressure chamber communicate selectively with the atmosphere and the constant pressure chamber. The brake booster device transmits the axial movement of the diaphragm generated based on the pressure difference between the both chambers, from the piston through a reaction mechanism to an output rod. The output rod pulls a piston rod of a master cylinder rearward for making the master cylinder generate a braking pressure. The output rod extends as the piston rod in the master cylinder of the master cylinder device, and a master piston is mounted on the forward end portion of the piston rod so that it is floatable relative to the piston rod, but is restrained from being moved forward relative to the piston rod in the axial direction of the same. Thus, the master piston can be prevented from scraping against the master cylinder.

Abstract: If a condition for starting a yaw control during an antiskid control is met while the antiskid control is being executed on one of right and left front wheels during braking on a uneven friction-coeffient road surface, the reference value for making the determination to start the antiskid control on the other one of the front wheels is reduced, and therefore the antiskid control is started at an earlier timing. If the antiskid control is executed on the wheel, the brake pressure of the wheel is controlled in a pre-set specific pattern.
