Abstract: A brake ECU of a vehicle braking control device, during execution of brake pressurization control, performs actuation restriction control that restricts actuation of a motor as an arbitrary upstream fluid pressure (M/C pressure) that is the brake pressure input from the M/C side of the brake fluid pressure control actuator becomes higher. The brake ECU has a threshold value changing unit that sets at least the starting threshold value at a high level when the upstream fluid pressure (M/C pressure) is high compared to when low, and as actuation restriction control actuates the motor to pump out the brake fluid from inside of the reservoirs when the reservoir fluid volume exceeds the starting threshold value, and stops the motor when the reservoir fluid volume equals the stop threshold value.

Abstract: A vehicle brake control device performs select-low anti-lock brake control. In the select-low anti-lock brake control, in a decrease period, in which braking force on a first wheel that is one of left and right wheels that has a lower wheel speed is decreased, braking force on a second wheel that is one of the left and right wheels that has a higher wheel speed is also decreased. In an increase period, in which the braking force on the first wheel is increased, the braking force on the second wheel is also increased. The vehicle brake control device is configured such that, when performing the anti-lock brake control, the vehicle brake device sets the braking force on the second wheel to be greater when the tendency for instability in the vehicle behavior is small than when such tendency is large.

Abstract: The present invention is provided with a power transmission member rotatably supported by a caliper, and a ratchet wheel fixed by the member. A first linear direction movement of a pawl member that engages with a mobile member of a solenoid is guided by a guide member fixed by the caliper. The pawl member is continuously pressed in a release direction by an elastic member. The interlocking force in an interlocking direction, imparted by mobile member of the solenoid mobile member to the pawl member, and the release force in the release direction, which is imparted by the elastic member to the pawl member oppose each other, and the interlocking force is larger than the release force. The pawl member and the mobile member move linearly together in one of the interlocking direction and the release direction.

Abstract: To enable control of vehicle speed according to the intentions of a driver by a simpler operation. When a vehicle body speed rapidly decreases and becomes lower than a brake target threshold speed, the brake target threshold speed is decreased in conformity with the vehicle body speed. This prevents the increase of the vehicle body speed toward the brake target threshold speed such that a vehicle accelerates regardless of a brake being in operation because the brake target threshold speed is set at a higher value than the vehicle body speed. Accordingly, the vehicle body speed decelerates by a simpler operation while being able to prevent the vehicle from accelerating against the intentions of a driver and being able to control the speed of the vehicle according to the intentions of the driver.

Abstract: A vehicular brake device that implements ESC/TRC control suppresses hydraulic pressure variations produced during open/close control of a brake actuator holding valve or depressurizing valve. While a brake operating member is not operated and a wheel cylinder pressure supplying control is executed to supply target wheel cylinder pressure to respective wheel cylinders, the target servo pressure is set to a first predetermined target servo pressure smaller than a maximum output pressure of the servo pressure generating device. When wheel cylinder pressure supplying control starts, the target servo pressure is set as the target wheel cylinder maximum value when a firstly occurred rising inclination of the target wheel cylinder maximum value is equal to or more than a minimum increment of an output of the servo pressure generating device per unit time and at the same time when the target wheel cylinder pressure is below the first determined target servo pressure.
