Abstract: The vehicle braking control device adapted to a vehicle brake device having an electromagnetic valve which controls the brake fluid flow between the master cylinder and the wheel cylinders in response to the input electric energy. The vehicle braking control device includes a valve opening electric energy obtaining portion which obtains an input electric energy upon opening of the electromagnetic valve as a valve opening electric energy and an operation characteristic setting portion which sets an operation characteristic based on the valve opening electric energy obtained corresponding to the predetermined pressure differential. The opening valve electric energy obtaining portion changes the input electric energy at a valve closing side or a valve opening side with a change amount per unit of time larger than before valve opening in response to an obtaining of the valve opening electric energy.

Abstract: A brake control device for a vehicle which can prevent occurrence of hunting or stepping during braking control operation and includes a pressure increasing or decreasing characteristic selecting portion which selects a pressure increasing characteristic when a target wheel cylinder pressure increases continuously for a predetermined operation judgment period and selects a pressure decreasing characteristic when the target wheel cylinder pressure decreases continuously for a predetermined operation judgment period. The brake control device further includes an output servo pressure setting portion which sets a target servo pressure based on the pressure increasing or decreasing characteristic selected by the pressure increasing or decreasing characteristic selecting portion and a servo pressure generating device which generates a servo pressure based on the target servo pressure.

Abstract: A hydraulic brake system is configured such that a pressure of a working fluid from a high-pressure-source device is adjusted by electromagnetic pressure-increase and pressure-decrease linear valves and such that a brake device generates a braking force having a magnitude that depends on the pressure adjusted by the linear valves, wherein the following controls are selectively executable, as a control of the energizing currents supplied to the linear valves, a feedback control based on a difference between an actual braking-force index and a target braking-force index; and a feedforward control based on the target braking-force index executed by placing each valve in a valve equilibrium state, wherein, in the feedforward control, an energizing current is supplied to at least one of the two linear valves, the energizing current being larger than that according to a preset relationship between a braking-force index and an energizing current in the valve equilibrium state.
