Abstract: The vehicle braking device performs a control which makes an actual value of physical quantity associated with a braking force follow a target value thereof when the actual value is outside a dead zone and a control which suppresses a change of the actual value when the actual value is within the dead zone and includes a judging portion which judges whether or not the actual value passes through the dead zone with a value beyond the upper limit threshold value and a setting portion which sets a second upper limit threshold value more closely approximated than a first upper limit threshold value when the actual value is judged not to pass through the dead zone, as the upper limit threshold value, when the actual value is judged to pass through the dead zone by the judging portion.

Abstract: Brake fluid inside a first wheel cylinder is pressurized by using a first pressure-regulating mechanism and brake fluid inside a second wheel cylinder is pressurized by using a second pressure-regulating mechanism. If a determination means determines that the first pressure-regulating mechanism action is in an unsuitable state and the second pressure-regulating mechanism action is in a suitable state, the control means pressurizes the brake fluid inside the first wheel cylinder by using a master cylinder and pressurizes the brake fluid inside the second wheel cylinder by using the second pressure-regulating mechanism, when an operation volume is less than a value. When the operation volume has reached the value, the control means pressurizes the brake fluid inside the first and second wheel cylinders by using the second pressure-regulating mechanism.

Abstract: When braking force is applied to a vehicle by the operation of a brake actuator, this control device, which is a vehicle brake control device, calculates the time to stop TTS on the basis of the relationship between the vehicle speed VS and the vehicle deceleration DVS. In addition, when the calculated time to stop TTS becomes less than a restriction determination time TTSTH, the control device stops the operation of the supply pumps of the brake actuator.

Abstract: This electric braking device uses drive torque of an electric motor to push a friction member against a rotating member secured to a vehicle wheel and produce braking torque in the vehicle wheel. This device comprises a body power source for electric motor power supply secured to a body of the vehicle, and a vehicle wheel power source for electric motor power supply secured to the vehicle wheel. The body power source supplies power to the vehicle wheel power source via a first electric path, and the vehicle wheel power source supplies power to the electric motor via a second electric path. When braking torque is produced in the vehicle wheel, the electric motor is normally driven using the vehicle wheel power source. An electric braking device is thereby provided in which a power line electrically connecting the body side and the vehicle wheel side bends readily.

Abstract: In the present invention, when a first protrusion of a shaft abuts on a guide face thereby pressing a first valve element toward the top as seen in the drawing, the guide face is separated from a cylinder seat face, and a large-diameter oil passage is opened. At this time, when the first protrusion abuts on the guide face thereby driving the first valve element to the position where the valve opens, the first valve element is also pressed in a direction perpendicular to the reciprocating direction of the first valve element because the guide face has a spherical surface or a tapered surface. Thus, the first valve element is supported at two points, point E and point F or G, thereby dampening vibrations.
