Abstract: Braking torque is automatically applied based on requested deceleration and requested distance from a driving assistance device. Standard deceleration decreases in an “upwardly curved” form and then decreases in a “downwardly curved” form over time in a standard deceleration profile, and a standard speed profile corresponds to the standard deceleration profile. In the present calculation period, target deceleration and target speed profiles are set by adjusting the standard deceleration/standard speed profiles to satisfy the relationship between deceleration and vehicle body speed. The estimated distance from the reference speed to the vehicle stop is calculated based on the target speed profile. In a condition that the estimated distance is equal to/less than the requested distance is denied, braking torque is adjusted based on requested deceleration.

Abstract: A braking control device includes: a master cylinder having a master chamber defined by a master piston; and a first pressure regulation unit having a servo chamber located on an opposite side of the master chamber and supplying a servo pressure to the servo chamber to generate a master pressure in the master chamber. The first pressure regulation unit acquires the master pressure and servo pressure and determines bottoming out of the master piston based on a comparison between the master and servo pressures. The first pressure regulation unit may make the comparison based on pressure-receiving area of the servo chamber and a pressure-receiving area of the master chamber. If the servo chamber pressure-receiving area is equal to the master chamber pressure-receiving area, the first pressure regulation unit determines bottoming out occurs when a difference between the servo pressure and the master pressure equals or exceeds a predetermined pressure.
